What are the benefits of Vitamin C 500mg. How does it affect your health. What are the potential side effects of taking Vitamin C supplements. When should you consult a doctor before taking Vitamin C.

The Importance of Vitamin C in Your Diet

Vitamin C, also known as ascorbic acid, is an essential nutrient that plays a crucial role in maintaining overall health. Our bodies cannot produce this vitamin on their own, making it necessary to obtain it through diet or supplementation. But why is Vitamin C so important?

Vitamin C is a powerful antioxidant that helps protect cells from damage caused by free radicals. It also supports the immune system, promotes the production of collagen, and aids in the absorption of iron from plant-based foods. These functions make Vitamin C vital for various bodily processes, including wound healing, maintaining healthy skin, and supporting cardiovascular health.

Natural Sources of Vitamin C

While supplements like Vitamin C 500mg tablets are readily available, it’s generally recommended to obtain this nutrient from dietary sources. Some excellent natural sources of Vitamin C include:

• Citrus fruits (oranges, lemons, grapefruits)
• Berries (strawberries, blueberries, raspberries)
• Kiwi fruit
• Bell peppers
• Broccoli
• Brussels sprouts
• Potatoes
• Tomatoes

Incorporating these foods into your daily diet can help ensure you’re meeting your Vitamin C needs without relying solely on supplements.

Understanding Vitamin C 500mg Supplements

Vitamin C 500mg supplements are a popular choice for those looking to boost their intake of this essential nutrient. But what exactly does the “500mg” designation mean?

The 500mg refers to the dosage of Vitamin C in each tablet or capsule. This amount is significantly higher than the recommended daily intake, which is 65-90mg for adults. The higher dosage in supplements is designed to provide a more concentrated source of Vitamin C, especially for those who may have difficulty obtaining enough from their diet alone.

Are Vitamin C 500mg Supplements Necessary?

For most healthy individuals consuming a balanced diet rich in fruits and vegetables, Vitamin C 500mg supplements may not be necessary. However, certain groups of people might benefit from supplementation:

• Smokers
• People with limited access to fresh fruits and vegetables
• Individuals with certain medical conditions that affect nutrient absorption
• Those under significant physical stress (e.g., athletes, manual laborers)

It’s always best to consult with a healthcare professional before starting any new supplement regimen, including Vitamin C 500mg.

Potential Benefits of Vitamin C Supplementation

While obtaining Vitamin C from dietary sources is ideal, supplementation can offer several potential benefits. Research has shown that Vitamin C supplements may help in various health aspects:

Immune System Support

Can Vitamin C really boost your immune system? While it’s not a miracle cure, studies have shown that Vitamin C plays a crucial role in supporting immune function. It helps stimulate the production and function of white blood cells, which are essential for fighting off infections and diseases.

Cardiovascular Health

Some research suggests that Vitamin C supplementation may have positive effects on heart health. It may help reduce high blood pressure and lower the risk of heart disease by improving the function of blood vessels.

Skin Health

Vitamin C is essential for the production of collagen, a protein that gives structure to skin, bones, and blood vessels. Supplementation may help improve skin texture and reduce the appearance of wrinkles.

Iron Absorption

Vitamin C enhances the absorption of non-heme iron, the type of iron found in plant-based foods. This can be particularly beneficial for vegetarians and vegans who rely on plant sources for their iron intake.

Potential Side Effects of Vitamin C 500mg

While Vitamin C is generally considered safe, high doses such as those found in 500mg supplements can sometimes cause side effects. It’s important to be aware of these potential issues:

Digestive Discomfort

The most common side effects of high-dose Vitamin C supplements are related to the digestive system. These may include:

• Nausea
• Abdominal cramps
• Diarrhea
• Bloating

These symptoms are typically mild and can often be alleviated by taking the supplement with food or reducing the dosage.

Increased Risk of Kidney Stones

Does Vitamin C supplementation increase the risk of kidney stones? Some studies suggest that high doses of Vitamin C may increase the risk of kidney stone formation in susceptible individuals. This is because Vitamin C can be converted to oxalate in the body, a compound that can contribute to kidney stone formation.

Interference with Medical Tests

High doses of Vitamin C can interfere with certain medical tests, potentially leading to false results. These may include tests for blood sugar, cholesterol, and occult blood in stool samples.

Iron Overload

While Vitamin C enhances iron absorption, this can be problematic for individuals with conditions that cause iron accumulation, such as hemochromatosis. In these cases, excessive Vitamin C intake could lead to iron overload.

Precautions and Interactions with Vitamin C 500mg

When considering Vitamin C 500mg supplements, it’s crucial to be aware of potential interactions with medications and certain health conditions:

Medication Interactions

Vitamin C can interact with several types of medications, including:

• Blood thinners (e.g., warfarin)
• Chemotherapy drugs
• Estrogen-containing medications
• Statins

If you’re taking any medications, it’s essential to consult with your healthcare provider before starting Vitamin C supplementation.

Health Conditions

Certain health conditions may require caution when taking high-dose Vitamin C supplements:

• Diabetes: High doses of Vitamin C may interfere with blood sugar tests.
• Kidney disease: Impaired kidney function can affect Vitamin C metabolism.
• G6PD deficiency: A genetic condition that can lead to hemolytic anemia with high Vitamin C intake.

Always discuss your medical history with a healthcare professional before starting any new supplement regimen.

Proper Dosage and Administration of Vitamin C 500mg

While Vitamin C 500mg supplements are widely available, it’s important to understand proper dosage and administration to maximize benefits and minimize potential side effects.

Recommended Dosage

The recommended dietary allowance (RDA) for Vitamin C varies by age and gender:

• Adult men: 90mg per day
• Adult women: 75mg per day
• Pregnant women: 85mg per day
• Breastfeeding women: 120mg per day

However, the 500mg dosage in supplements is generally considered safe for most adults. The tolerable upper intake level is set at 2000mg per day for adults.

Timing and Administration

When is the best time to take Vitamin C 500mg supplements? Vitamin C can be taken at any time of day, but taking it with meals may help reduce the risk of digestive side effects. If you’re using Vitamin C to enhance iron absorption, it’s best to take it along with iron-rich foods.

For those new to Vitamin C supplementation, it may be advisable to start with a lower dose and gradually increase to 500mg to assess tolerance.

Reviews and Effectiveness of Vitamin C 500mg Supplements

The effectiveness of Vitamin C 500mg supplements can vary depending on individual factors and specific health conditions. While many users report positive experiences, it’s important to approach supplement use with realistic expectations.

User Reviews

Many users of Vitamin C 500mg supplements report benefits such as:

• Improved immune function and fewer colds
• Better skin health and appearance
• Increased energy levels
• Faster wound healing

However, it’s important to note that individual experiences can vary, and these reports are anecdotal.

Scientific Evidence

Scientific research on the effectiveness of Vitamin C supplementation has shown mixed results. While some studies support its use for certain conditions, others have found no significant benefit.

For example, research has shown that Vitamin C supplementation may reduce the duration of common colds, but it does not appear to prevent them in the general population. Studies on its effectiveness for other conditions, such as cardiovascular disease and cancer prevention, have been inconclusive.

Choosing the Right Vitamin C 500mg Supplement

With numerous Vitamin C 500mg supplements available on the market, choosing the right one can be overwhelming. Here are some factors to consider:

Form of Vitamin C

Vitamin C supplements come in various forms, including:

• Ascorbic acid (the most common and typically least expensive form)
• Sodium ascorbate
• Calcium ascorbate
• Liposomal Vitamin C

Some people find that certain forms are gentler on the stomach or more easily absorbed. Experimenting with different forms may help you find the one that works best for you.

Additional Ingredients

Some Vitamin C supplements include additional ingredients such as bioflavonoids or rose hips, which are thought to enhance absorption and effectiveness. However, scientific evidence supporting these claims is limited.

Quality and Purity

Look for supplements that have been third-party tested for purity and potency. Certifications from organizations like USP (United States Pharmacopeia) or NSF International can provide assurance of quality.

Cost

While cost shouldn’t be the only factor, it’s worth comparing prices among reputable brands. Remember that the most expensive option isn’t necessarily the best.

By considering these factors and consulting with a healthcare professional, you can make an informed decision about which Vitamin C 500mg supplement is right for you.

Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Overview

Vitamin C is an essential vitamin that must be consumed in the diet. Good sources include fresh fruits and vegetables, especially citrus fruits.

Vitamin C is needed for the body to develop and function properly. It plays an important role in immune function. Most experts recommend getting vitamin C from the diet rather than taking supplements. Fresh oranges and fresh-squeezed orange juice are good sources.

Historically, vitamin C was used for preventing and treating scurvy. Today, people most commonly use vitamin C for preventing and treating the common cold. It’s also used for autism, breast cancer, heart disease and many other conditions, but there is no good scientific evidence to support many of these uses. There is also no good evidence to support using vitamin C for COVID-19.

Uses & Effectiveness ?

Effective for

• Vitamin C deficiency. Taking vitamin C by mouth or injecting it as a shot prevents and treats vitamin C deficiency, including scurvy. Also, taking vitamin C can reverse problems associated with scurvy. Only a healthcare provider can inject vitamin C as a shot.

Possibly Effective for

• Low levels of red blood cells in people with a long-term illness (anemia of chronic disease). Taking vitamin C supplements by mouth might help manage anemia in people undergoing dialysis.
• Irregular heartbeat (atrial fibrillation). Taking vitamin C by mouth or by IV before and after heart surgery helps prevent irregular heartbeat after heart surgery. IV products can only be given by a healthcare provider.
• Emptying the colon before a colonoscopy. A specific fluid containing vitamin C (MoviPrep, Salix Pharmaceuticals, Inc.) has been approved by the FDA for bowel preparation before a colonoscopy. Some bowel preparations involve drinking 4 liters of medicated fluid. If vitamin C is included in the fluid, only 2 liters are needed.
• Common cold. Taking 1-3 grams of vitamin C by mouth might shorten the course of a cold by 1 to 1.5 days. But taking vitamin C does not appear to prevent colds.
• Limb pain that usually occurs after an injury (complex regional pain syndrome). Taking vitamin C by mouth after surgery or injury seems to prevent complex regional pain syndrome from developing.
• Recovery from laser skin therapy. Applying a skin cream containing vitamin C might decrease skin redness after laser skin therapy for scar and wrinkle removal.
• Airway infections caused by exercise. Taking vitamin C by mouth before heavy physical exercise, such as a marathon or army training, might prevent upper airway infections that can occur after heavy exercise.
• High cholesterol. Taking vitamin C by mouth might reduce low-density lipoprotein (LDL or “bad”) cholesterol in people with high cholesterol.
• High blood pressure. Taking vitamin C by mouth might help lower systolic blood pressure (the top number in a blood pressure reading) by a small amount. But it does not seem to lower diastolic pressure (the bottom number).
• Lead poisoning. Consuming vitamin C in the diet seems to lower blood levels of lead.
• Reduced benefit of nitrate therapy that happens when nitrates are used all day (nitrate tolerance). Taking vitamin C by mouth seems to help drugs for chest pain, such as nitroglycerin, to work longer.
• Pain after surgery. Taking vitamin C by mouth or by IV might reduce pain during the first 24 hours after surgery. But it’s unclear if taking vitamin C by mouth can reduce pain during the first 6 weeks after surgery. IV products can only be given by a healthcare provider.
• Wrinkled skin. Applying skin creams containing vitamin C seems to improve the appearance of wrinkled skin. Apply a vitamin C patch also seems to help reduce wrinkles.

Possibly Ineffective for

• Short-term swelling (inflammation) of the airways in the lungs (acute bronchitis). Taking vitamin C by mouth does not seem to have any effect on bronchitis.
• Asthma. Taking vitamin C by mouth doesn’t seem to prevent asthma or improve symptoms in people who already have asthma.
• Hardening of the arteries (atherosclerosis). Taking vitamin C by mouth does not seem to prevent atherosclerosis from becoming worse in most people with this condition.
• Bladder cancer. Taking vitamin C by mouth does not seem to prevent bladder cancer or reduce bladder cancer-related deaths.
• Heart disease. Taking vitamin C by mouth does not prevent heart disease or reduce death due to heart disease.
• Colon cancer, rectal cancer. Taking vitamin C by mouth does not seem to prevent cancer in the colon or rectum.
• Coronavirus disease 2019 (COVID-19). Taking high-dose vitamin C by mouth does not seem to speed up recovery from COVID-19 in people who aren’t in the hospital. Giving vitamin C by mouth or IV to people who are in the hospital with severe COVID-19 might have some benefit, but more studies are needed to say for sure.
• Death of an unborn or premature baby. Taking vitamin C by mouth, alone or with other supplements, during pregnancy doesn’t prevent death of an unborn or premature baby.
• Fractures. Taking vitamin C by mouth does not seem to improve function, symptoms, or healing rates in people with a wrist fracture.
• A digestive tract infection that can lead to ulcers (Helicobacter pylori or H. pylori). Taking vitamin C by mouth along with medicines used to treat H. pylori infection doesn’t seem to get rid of H. pylori faster than taking the medicines alone.
• A group of inherited disorders that leads to muscle weakness and numbness in the arms and legs. Taking vitamin C by mouth for one or two years does not seem to prevent nerve damage in people with these disorders.
• Eye damage in people taking drugs called interferons (interferon-related retinopathy). Taking vitamin C by mouth does not seem to prevent eye damage in people receiving interferon therapy for liver disease.
• Cancer of the white blood cells (leukemia). Taking vitamin C by mouth doesn’t seem to prevent leukemia or death due to leukemia.
• Lung cancer. Taking vitamin C by mouth, alone or with vitamin E, doesn’t seem to prevent lung cancer or death due to lung cancer.
• The most serious type of skin cancer (melanoma). Taking vitamin C by mouth, alone or with vitamin E, doesn’t prevent melanoma or death due to melanoma.
• Miscarriage. Taking vitamin C by mouth, alone or with other supplements, during pregnancy does not prevent miscarriage.
• Death from any cause. Taking vitamin C by mouth along with other antioxidants does not seem to prevent death.
• Pancreatic cancer. Taking vitamin C by mouth together with beta-carotene plus vitamin E does not seem to prevent pancreatic cancer.
• A pregnancy complication marked by high blood pressure and protein in the urine (pre-eclampsia). Taking vitamin C by mouth with vitamin E during pregnancy does not prevent high blood pressure and protein in the urine during pregnancy.
• Preterm birth. Taking vitamin C by mouth, alone or with other supplements, during pregnancy does not prevent preterm birth.
• Prostate cancer. Taking vitamin C by mouth does not seem to prevent prostate cancer.
• Skin damage caused by radiation therapy (radiation dermatitis). Applying a vitamin C solution to the skin does not prevent skin problems caused by radiation treatments.
• Blood infection (sepsis). Giving vitamin C by IV with or without thiamine does not reduce the risk of dying or the need for supportive treatment in people with sepsis. IV products can only be given by a healthcare provider.
• Infants with birth weight below the 10^th percentile. Taking vitamin C by mouth, alone or with other supplements, during pregnancy does not reduce the chance of giving birth to an infant with a low birth weight.
• Stillbirth. Taking vitamin C by mouth, alone or with other supplements, during pregnancy does not reduce the chance of having a stillbirth.

There is interest in using vitamin C for a number of other purposes, but there isn’t enough reliable information to say whether it might be helpful.

Side Effects

When taken by mouth: Vitamin C is likely safe for most people. In some people, vitamin C might cause side effects such as stomach cramps, nausea, heartburn, and headache. The chance of getting these side effects increases with higher doses. Taking more than 2000 mg daily is possibly unsafe and may cause kidney stones and severe diarrhea. In people who have had a kidney stone, taking amounts greater than 1000 mg daily increases the risk of getting more kidney stones.

When applied to the skin: Vitamin C is likely safe for most people. It might cause irritation and tingling.

Special Precautions and Warnings

Pregnancy and breast-feeding: Vitamin C is likely safe to take by mouth during pregnancy in amounts no greater than 2000 mg daily for those 19 years and older and 1800 mg daily for those 14-18 years old. Taking too much vitamin C during pregnancy can cause problems for the newborn baby. Vitamin C is possibly unsafe when taken by mouth in excessive amounts.

Infants and children: Vitamin C is likely safe when taken by mouth appropriately. Vitamin C is possibly unsafe when taken by mouth in amounts higher than 400 mg daily for children 1-3 years, 650 mg daily for children 4-8 years, 1200 mg daily for children 9-13 years, and 1800 mg daily for adolescents 14-18 years.

Alcohol use disorder: People who regularly use alcohol, especially those who have other illnesses, often have vitamin C deficiency. These people might need to be treated for a longer time than normal to restore vitamin C levels to normal.

Cancer: Cancerous cells collect high concentrations of vitamin C. Until more is known, only use high doses of vitamin C under the direction of your oncologist.

Chronic kidney disease: Long-term kidney disease might increase the risk of vitamin C deficiency. Vitamin C supplements might also increase the amount of oxalate in the urine in some people. Too much oxalate in the urine can increase the risk of kidney failure in people with kidney disease.

A metabolic deficiency called “glucose-6-phosphate dehydrogenase” (G6PD) deficiency: Large amounts of vitamin C can cause red blood cells to break in people with this condition. Avoid excessive amounts of vitamin C.

Kidney stones: Large amounts of vitamin C can increase the chance of getting kidney stones. Do not take vitamin C in amounts greater than those found in basic multivitamins.

Smoking and chewing tobacco: Smoking and chewing tobacco lowers vitamin C levels. People who smoke or chew tobacco should consume more vitamin C in the diet.

Interactions ?

Moderate Interaction

Be cautious with this combination

• Aluminum is found in most antacids. Vitamin C can increase how much aluminum the body absorbs. However, it is not clear if this interaction is a big concern. Take vitamin C two hours before or four hours after antacids.

• Vitamin C might decrease how quickly the body gets rid of estrogens. Taking vitamin C along with estrogens might increase the effects and side effects of estrogens.

• Large amounts of vitamin C might decrease how much fluphenazine is in the body. Taking vitamin C along with fluphenazine might decrease the effectiveness of fluphenazine.

• Vitamin C is an antioxidant. There is some concern that antioxidants might decrease the effects of some medications used for cancer. If you are taking medications for cancer, check with your healthcare provider before taking vitamin C.

• Taking niacin with vitamin C and other antioxidants can decrease the effects of niacin on good cholesterol levels. It is unknown if vitamin C alone decreases the effects of niacin on good cholesterol levels.

• Warfarin is used to slow blood clotting. Large amounts of vitamin C might decrease the effects of warfarin. Decreasing the effects of warfarin might increase the risk of clotting. Be sure to have your blood checked regularly. The dose of your warfarin might need to be changed.

• Taking large amounts of vitamin C along with indinavir might decrease how much indinavir stays in the body. It’s not clear if this interaction is a big concern.

• Vitamin C is an antioxidant. There is some concern that antioxidants might decrease the effects of medications used for cancer. If you are taking medications for cancer, check with your healthcare provider before taking vitamin C.

• Taking vitamin C along with levothyroxine might increase how much levothyroxine the body absorbs. This can increase the amount of levothyroxine in the body and increase its effects and side effects.

Minor Interaction

Be watchful with this combination

• The body breaks down acetaminophen to get rid of it. Large amounts of vitamin C can decrease how quickly the body breaks down acetaminophen. It is not clear if this interaction is a big concern.

• Aspirin is removed by the body through the kidneys and in the urine. Vitamin C might decrease how the body removes aspirin and could potentially increase the amount of aspirin in the body. But it’s not clear if this is a big concern.

• Vitamin C might decrease how quickly the body gets rid of choline magnesium trisalicylate. It is not clear if this interaction is a big concern.

• Vitamin C might decrease how quickly the body gets rid of salsalate. Taking vitamin C along with salsalate might cause too much salsalate in the body, and increase the effects and side effects of salsalate.

Dosing

Vitamin C is an important nutrient. Fresh fruits and vegetables, especially citrus fruits, are good sources of vitamin C. The amount that should be consumed on a daily basis is called the recommended dietary allowance (RDA). For adult males, the RDA is 90 mg daily. For females 19 years and older, the RDA is 75 mg daily. While pregnant and breastfeeding, the RDA is 120 mg daily for people 19-50 years old. In children, the RDA depends on age.

Vitamin C is also available in supplements, combination products, liquids, lotions, creams, serums, sprays, and patches. Supplements have been used safely by adults in doses up to 2000 mg daily. Speak with a healthcare provider to find out what type of product and dose might be best for a specific condition.

Vitamin C for colds and flu – benefits and properties

Vitamin C (ascorbic acid) is useful for metabolism, hormone production, protection against free radicals. It also helps the body fight infections – doctors prescribe vitamin C for colds and flu. Means based on it are used to prevent frequent SARS.

Ascorbic acid is needed by all organs and tissues. But the human body does not produce it and does not accumulate. Therefore, foods and preparations with a high vitamin content should be consumed daily. We will tell you where ascorbic acid is contained, how to choose and take the drug correctly.

General properties of vitamin C

Ascorbic acid is involved in the most important processes of the body:

● Synthesizes collagen – fibers that strengthen connective tissue. If there is enough vitamin C, the walls of blood vessels retain elasticity, and the skin remains youthful.

● Produces sex and adrenal hormones.

● It has an antioxidant effect – protects against reactive oxygen compounds that provoke aging and the development of malignant tumors.

● Strengthens the immune system. ¹

The lack of ascorbic acid (hypovitaminosis C) leads to fatigue, decreased performance, constant colds. And its pronounced deficiency (avitaminosis C) causes scurvy, which leads to anemia, affects the joints and gums. Vitamin deficiency is rare in developed countries, and hypovitaminosis is a common problem.

Vitamin C benefits for colds and flu

Ascorbic acid is often prescribed for the treatment and prevention of colds. It works in several directions at once:

● Increases immunity. Resistance to viruses cannot depend only on drugs – the body must be able to resist infections. Ascorbic acid affects all parts of the immune response: it promotes the production of antiviral interferons and antibodies.

● Reduces the impact of adverse factors leading to colds. Bad ecology creates an additional burden on the immune system. Vitamin C supports it by neutralizing the harmful effects of free radicals and reduces the risk of developing diseases and exacerbations.

● Helps to bear the disease more easily.
Ascorbic acid for colds and flu has an anti-inflammatory effect, reduces intoxication of the body.

Unlike many prescription drugs, vitamin C is safe. It dissolves in water, is absorbed into the intestinal wall, and the excess is easily excreted from the body. The use of ascorbic acid practically does not cause side effects and overdose. ²

How to take vitamin C for a cold

Vitamin C must be taken daily. The daily dose is about 30–120 mg, but the exact dosage depends on the individual characteristics of the body, lifestyle, and medication. The maximum safe dose is 2-3 g.

Average daily requirement for ascorbic acid (mg): ^3.4.5

● Children – 30-60.

● Teenagers – 80.

● Adults – 70-100. The minimum dose of vitamin C required by pregnant women is 60 mg, while nursing mothers need 80 mg.

In higher doses of ascorbic acid need:

● smokers and people who drink alcohol;

● everyone who is on mono-diets;

● women taking combined hormonal contraceptives or undergoing estrogen therapy for menopause;

● patients who are treated for a long time with corticosteroids, acetylsalicylic acid, antibiotics, calcium preparations;

● Patients exposed to influenza and ARVI viruses;

● residents of latitudes with extremely cold or hot climates and those who are constantly exposed to hypothermia/overheating;

● Elderly – The dose depends on chronic diseases and their treatment.

To determine if you have hypovitaminosis and calculate an individual dose, take a blood test for vitamin C.

During the outbreak of SARS, vitamin C increases the body’s resistance. Studies have shown that a daily intake of 200 mg of ascorbic acid reduces the incidence of acute respiratory viral infections by 50%, and in those who are sick, it speeds up recovery. ⁶

For a quick recovery from a cold, symptomatic treatment or taking vitamins is not enough. It is important to use drugs directed specifically against the causative agent of the disease. With the viral nature of the disease – influenza, SARS – the patient is shown broad-spectrum antiviral drugs. An effective new agent that helps to suppress the action of a variety of pathogens that cause viral infections is Nobasit ^® Forte (INN enisamia iodide). Taking enisamium iodide in combination with ascorbic acid, the daily dosage of which is determined by the relevant instructions for medical use, increases the body’s resistance to SARS and influenza. ⁷

Vitamin C sources

Our body can get ascorbic acid from food and from vitamin preparations. Some people believe that pharmacy forms are less useful and less digestible, but this is not so.

What foods contain vitamin C

Vitamin C is rich in plant foods – fruits, berries, vegetables. Main sources of vitamin C (per 100 g of product): ⁸

● Sea buckthorn, currant – 200 mg;

● Kiwi – 180 mg;

● Dill – 100 mg;

● Cauliflower – 70 mg;

● Oranges, bell peppers – 60 m;

● Spinach – 55 mg;

● White cabbage, grapefruits – 45 mg;

● Sorrel – 43 mg;

● Lemons – 40 mg;

● Mandarin – 38 mg;

● Garlic – 30 mg;

● Radishes, tomatoes, onions, raspberries – 25 mg.

In order for the body to receive enough ascorbic acid, you can eat a lemon, or an orange, or 4-5 apples daily. A good source of the vitamin is freshly squeezed juices. To close the daily need for vitamin C, it is enough to drink 116 ml of lemon juice, 150 ml of orange, or 1 liter of apple. ⁹

Vitamin C is destroyed during heat treatment and long-term storage of fruits. In addition, with many diseases of the gastrointestinal tract, the use of raw fruits and vegetables is not recommended. An alternative is ready-made preparations with ascorbic acid.

How to choose a vitamin C supplement

In pharmacy vitamin preparations, the concentration of ascorbic acid is higher than in products.

Natural preparations are made from natural raw materials – rose hips, currant leaves, rowan berries. They are dried and crushed to make syrups. Dried fruits and leaves have a lower concentration of vitamin C, but do not contain auxiliary substances – sweeteners, dyes. Such components may have contraindications – allergies, some metabolic diseases.

Tablets and powders are synthesized artificially. However, they are just as safe and effective as natural ones – they repeat the processes of natural synthesis in the laboratory. They are more convenient to take and dose, but they also contain excipients that cause individual intolerance. Contraindications are indicated in the instructions for each drug.

Vitamin C is produced in tablets with glucose, as part of multivitamin complexes. Pure synthetic ascorbic acid without additives is also on sale – powder in sachets with a dosage of 2.5 g. Monopreparations (containing only ascorbic acid) are better to choose if you need an increased intake of vitamin C. Complex preparations contain the daily norm of all essential vitamins.

Precautions for use

Ascorbic acid is not recommended to be taken together or sequentially with certain antibiotics, warfarin, estrogens, vitamin B12, preparations with copper, selenium. Keep an interval of at least 2-3 hours between them.

Taking vitamin C reduces the effectiveness of:

● drugs against thrombosis – heparin, indirect anticoagulants;

● psychotropic drugs – neuroleptics;

● means based on alkaloids – some antitumor, antitussive, lowering blood pressure;

● biologically active additives – copper and selenium.

If you are taking these medications, talk to your doctor about taking vitamin C.

Refrain from high doses of vitamin C if you need to take a biochemical blood test. Ascorbic acid can distort the result of liver parameters, blood glucose ⁴ .

Contraindications

Vitamin C in doses greater than the daily dose is contraindicated in case of individual intolerance, thrombophlebitis and a tendency to thrombosis. To assess the risk of thrombotic complications, do a blood coagulogram.

Consultation with a doctor is required if the patient:

● diabetes mellitus;

● hereditary diseases – sideroblastic anemia, thalassemia, deficiency of glucose-6-phosphate dehydrogenase, hemochromatosis;

● tendency to form stones in the urinary system;

● increased secretion of the stomach – hyperacid gastritis, peptic ulcer;

● long-term treatment with anticoagulants;

● salt-free diet.

In these cases, taking vitamin C may worsen the condition.

Briefly about the main

➢ Vitamin C increases the body’s resistance to colds, supports immunity, helps prevent illness and alleviate its course.

Vitamin C is not synthesized or stored by the body, so it must be taken daily.

➢ To prevent deficiency of ascorbic acid, eat fresh fruits, vegetables and greens in summer, drink freshly squeezed juices, and from the beginning of autumn to the end of spring, include vitamin supplements in your diet.

➢ Canned juices and long-term storage fruits contain significantly less vitamin C than fresh foods.

➢ In the treatment of colds, increased dosages of vitamin C are needed. However, like any treatment, vitamin therapy requires consultation with a doctor.

for what it is needed, and instructions for the use of ascorbic acid

Published: 11.08.2021

Vitamin C (ascorbic acid) was first synthesized about a hundred years ago – at 1932 year. At the same time, it was found that it was the lack of vitamin C that was the main cause of scurvy, which claimed the lives of a huge number of sailors. Later, many more discoveries were made related to ascorbic acid, and today this vitamin is prescribed for the prevention and treatment of a variety of diseases.

Signs of vitamin C deficiency

To maintain health, we need various vitamins, but ascorbic acid can rightfully be called one of the key micronutrients, since its deficiency often leads to negative consequences. Meanwhile, you can determine whether you have enough vitamin C, even by external signs. The main manifestations of ascorbic acid deficiency are ² :

• malaise, weakness, lethargy;
• dryness and pallor of the skin;
• the appearance of hematomas and abrasions, even with minor injuries due to increased fragility of blood vessels;
• slow wound healing;
• fragility of nails and hair;
• joint pain;
• frequent colds due to a decrease in the overall resistance of the body;
• soreness, swelling, bleeding of gums, in severe cases loosening and loss of teeth;
• low mood, tearfulness, tendency to depression.

A slight lack of ascorbic acid is called hypovitaminosis, but if you do not see a doctor in time, hypovitaminosis can turn into beriberi – an acute lack of vitamin C.

Causes of vitamin C deficiency

There are not so many reasons why ascorbic acid deficiency occurs. We list the main ones ³ :

1. Nutrition low in micronutrients. A meager low-calorie diet, mono-diets, eating disorders are the main causes of ascorbic acid deficiency. Residents of the northern regions are also at risk of vitamin deficiency, where there are interruptions in the supply of fresh vegetables and fruits.
2. Smoking. Smokers are deficient in many micronutrients, but especially vitamin C. They require higher doses of the vitamin than non-smokers to meet their need for ascorbic acid. In order to prevent hypovitaminosis, smokers are advised to take this micronutrient constantly – several courses a year with short breaks.
3. Tendency to colds. Ascorbic acid belongs to anti-infectious vitamins: it is involved in phagocytosis and the production of antibodies, increases the protective properties of the epithelium of the respiratory tract. With frequent colds, the body consumes more vitamin C than usual, which can lead to a deficiency of this micronutrient.
4. Taking certain medications. Ascorbic acid deficiency can develop with long-term use of certain drugs that prevent its absorption.
5. Diseases of the gastrointestinal tract. In chronic diseases of the digestive system, the absorption of vitamin C from food may be impaired. If you do not consult a doctor in time and do not monitor the level of ascorbic acid, hypovitaminosis may develop.

According to the Ministry of Health, pregnant and lactating women are also at risk for hypovitaminosis of ascorbic acid. To prevent vitamin deficiency states, they need to be constantly monitored by a doctor and take vitamin-mineral complexes for pregnant and lactating women.

Which vitamin C to choose?

Vitamin C is available in two forms: natural and synthetic. We get a natural micronutrient from vegetables, fruits, berries, herbs, a synthetic micronutrient – from dietary supplements. In the summer, when we consume enough foods rich in vitamin C, there is no point in taking it extra. However, starting from late autumn until the end of spring, supplementation with vitamin C is highly recommended ⁴ . There are few fresh vegetables and fruits at this time of the year, and thermally processed foods lose most of the micronutrients.

Dietary supplements with vitamin C can be divided into two large groups: some do not cause irritation of the gastric mucosa (potassium, calcium, sodium ascorbates), others can adversely affect the gastric epithelium (L-ascorbic acid). L-ascorbic acid is as close as possible to the natural form of vitamin C, but it is better not to take it for people with hypersensitivity of the stomach.

If we talk about the forms of release, then vitamin C is best absorbed in the form of powders and effervescent tablets. However, if for some reason these forms do not suit you, you can choose another one, for example, in capsules or tablets.

What are the best vitamin C supplements and how to choose them?

Evalar offers a wide range of dietary supplements with vitamin C. You can choose a single micronutrient in the form of effervescent tablets with a dosage of 250 to 2000 mg or choose one of the complex products, which we will discuss later.

Zinc with vitamin C is perhaps the best solution for increasing the body’s resistance to infections. These micronutrients not only work well together, but also complement each other’s action.

Zinc in this combination prevents the reproduction of the virus in the cell ⁵ , protects lymphocytes from destruction ⁶ . In addition, it has a positive effect on the functioning of the thymus gland, which is called the “heart of the immune system.” Vitamin C enhances the synthesis of interferon proteins, which are the first to fight back against viruses, and has anti-inflammatory properties.

Effervescent tablets with beta-carotene, vitamins C and D can be an excellent immune support during the cold season and improve skin condition.

As we noted above, dry skin can be one of the signs of a lack of ascorbic acid. When the micronutrient deficiency is replenished, the condition of the skin is also normalized. Beta-carotene, or provitamin A, will also be helpful for those with skin problems, and it can also be a great aid in achieving an even tan. About the properties of vitamin D and its importance for the body, we also wrote repeatedly. Want to know more? Read the article “Vitamin D – the king of micronutrients.”

This amazing quartet will appeal to those who prefer complex products. Effervescent tablets with two trace elements and two vitamins can strengthen the immune system and reduce the risk of developing colds. Also, the course intake of dietary supplements can improve the condition of the reproductive system, skin, nails and hair, maintain the health of the heart and blood vessels, which is especially important during the coronavirus pandemic.

Please note that biologically active complexes with beta-carotene and selenium have no analogues and are produced only by Evalar.

To compensate for the deficiency of micronutrients, it is enough for adults to take 1 effervescent tablet per day, after dissolving it in a glass of water. The duration of the prophylactic course is at least 1 month. If necessary, after a short break, the course can be repeated.

Other Evalar complexes with vitamin C

Vitamin C is also present in many other products of the Evalar company, for example, as part of the dietary supplement Elder Immunity, which, in addition to vitamin C, includes zinc and black elderberry juice, a natural activator of the immune system. By the way, dietary supplements with elderberry are very popular in the West, but in Russia they are produced only by the Evalar company.

Also, ascorbic acid is part of the complex of effervescent vitamins of group B, here it contributes to a better absorption of these micronutrients and enhances their effect.

The whole series of Evalar effervescent vitamins has excellent taste properties, includes only natural ingredients, has a high dissolution rate, and is easily digested. Products are made from high quality raw materials, do not contain preservatives and gluten.

How to take vitamin C correctly?

If you prefer to take your micronutrients in a single form, look no further than vitamin C in the form of calcium ascorbate, which is available in two dosages of 100mg and 900mg.

The product with a dosage of 100 mg is recommended for those who do not experience major problems with immunity, but want to compensate for vitamin C deficiency and protect themselves from hypovitaminosis. Dosage variant 900 mg will be relevant during the cold season, especially when the first symptoms of malaise appear or for quick recovery after an illness.

Products with a dosage of 1000 mg and above are best chosen after consultation with your doctor. For complete assimilation, it is desirable to divide the daily dose into three doses. It is highly undesirable to exceed the recommended daily allowances of vitamin C on a regular or long-term basis. The negative consequences of an overdose of vitamin C can be expressed in allergic reactions, impaired renal function, and thrombosis.

You will find detailed information about the composition, indications, contraindications and use of effervescent vitamins in the card of the corresponding product. Choose micronutrients only from reliable and trusted companies. Take vitamins and be healthy!
