Are multivitamins necessary for optimal health. Who benefits most from multivitamin supplementation. What are the potential risks and benefits of taking a daily multivitamin. How do multivitamins impact specific populations and health conditions. When should you consider taking a multivitamin supplement.

The Prevalence of Multivitamin Use in Modern Society

In today’s health-conscious world, multivitamin supplements have become a staple in many households. Recent studies indicate that nearly half of all adults in the United States regularly consume vitamin supplements, with this figure rising to a staggering 70% among adults over 71 years of age. Approximately one-third of these individuals opt for comprehensive multivitamin pills, which typically contain around 26 different vitamins and minerals, often providing 100% of the Recommended Daily Allowance (RDA) for these micronutrients.

This widespread use raises an important question: Are multivitamins truly necessary for maintaining optimal health? To answer this, we must first understand the role of vitamins and minerals in our bodies and examine the circumstances under which supplementation may be beneficial or even essential.

Understanding Nutrient Deficiencies and Their Consequences

Historically, severe nutrient deficiencies have led to devastating health conditions. Scurvy, caused by vitamin C deficiency, beri-beri from lack of vitamin B1, pellagra due to insufficient vitamin B3, and rickets resulting from vitamin D deficiency are prime examples of such diseases. However, these conditions have become increasingly rare in developed countries, where access to a diverse range of foods, including fortified options, is generally more prevalent.

Despite this progress, nutrient deficiencies still persist in modern society. According to criteria set by the National Academy of Medicine, many Americans fall short of adequate intake for certain vitamins and minerals. For instance, more than 90% of the U.S. population fails to meet the Estimated Average Requirement for vitamin D and vitamin E from food sources alone.

Common Nutrient Deficiencies in Modern Diets

• Vitamin D
• Vitamin E
• Folate (especially important for women of childbearing age)
• Vitamin B12 (particularly in older adults)
• Iron (common in women and vegetarians)
• Magnesium
• Calcium

Understanding these common deficiencies can help individuals make informed decisions about their nutritional needs and whether multivitamin supplementation might be beneficial.

Identifying High-Risk Groups for Nutrient Deficiencies

While a balanced diet should provide most essential nutrients, certain groups are at higher risk for nutrient deficiencies and may benefit from multivitamin supplementation. These include:

Older Adults

As we age, our bodies face unique challenges in obtaining and absorbing nutrients. Older adults may experience difficulties in chewing and swallowing food, altered taste perceptions due to medication use, or reduced appetite stemming from isolation and loneliness. Additionally, the ability to absorb vitamin B12 from food sources often diminishes with age.

The National Academy of Medicine recommends that individuals over 50 years old consume foods fortified with vitamin B12 or take vitamin B12 supplements, as these forms are more easily absorbed than those found in natural food sources.

Pregnant Women and Women of Childbearing Age

Folate, a B vitamin, plays a crucial role in fetal development. Adequate folate intake can significantly reduce the risk of neural tube defects such as spina bifida and anencephaly. To be effective, folate must be present in sufficient quantities during the early weeks of pregnancy, often before a woman is aware she is pregnant.

Given that approximately half of all pregnancies in the U.S. are unplanned, the Centers for Disease Control and Prevention recommend that all women of childbearing age (15-45 years) consume 600 micrograms of folic acid daily. Prenatal multivitamins typically contain this amount of folate along with other essential nutrients for pregnancy, including iron, calcium, vitamin D, and DHA.

Individuals with Malabsorption Conditions

Various medical conditions can interfere with normal digestion and nutrient absorption, increasing the risk of deficiencies. These include:

• Celiac disease
• Ulcerative colitis
• Cystic fibrosis
• Gastric bypass surgery
• Whipple procedure
• Chronic illnesses causing excessive vomiting or diarrhea
• Alcoholism

Individuals with these conditions may require targeted supplementation to address specific nutrient deficiencies.

People Taking Certain Medications

Some medications can interfere with nutrient absorption or increase the body’s nutrient requirements. Examples include:

• Diuretics: May deplete magnesium, potassium, and calcium
• Proton pump inhibitors: Can impair vitamin B12, calcium, and magnesium absorption
• Levodopa and carbidopa: May reduce absorption of B vitamins, including folate, B6, and B12

Patients taking these medications should consult with their healthcare providers about potential nutrient deficiencies and appropriate supplementation strategies.

The Case for Vitamin D Supplementation

Vitamin D deserves special attention in the context of multivitamin supplementation. Unlike most other nutrients, it’s challenging to obtain adequate vitamin D solely through diet. Few foods naturally contain vitamin D, although some are fortified with it.

The primary natural source of vitamin D is sunlight exposure, which triggers its production in the skin. However, many people have insufficient levels due to limited sun exposure, use of sunscreen, or living in areas with less intense sunlight.

Forms of Vitamin D Supplements

Vitamin D supplements are available in two forms:

1. Vitamin D2 (ergocalciferol): Produced in plants and fungi
2. Vitamin D3 (cholecalciferol): Produced in animals, including humans

Both forms are effective in raising blood levels of vitamin D, but some studies suggest that D3 may be more potent and longer-lasting.

Given the widespread deficiency and the importance of vitamin D for bone health, immune function, and other bodily processes, many health professionals recommend vitamin D supplementation for most individuals, especially those with limited sun exposure or at high risk for deficiency.

Potential Benefits of Multivitamin Supplementation

While the necessity of multivitamins for everyone remains debatable, research has identified several potential benefits associated with their use:

Filling Nutritional Gaps

For individuals who struggle to maintain a balanced diet, multivitamins can help bridge nutritional gaps. This is particularly relevant for those with restricted diets, such as vegetarians or vegans, who may be at risk for specific nutrient deficiencies.

Supporting Healthy Aging

Some studies suggest that multivitamin use may support healthy aging by improving cognitive function and reducing the risk of age-related eye diseases like cataracts and macular degeneration.

Enhancing Mood and Mental Well-being

Research has indicated a potential link between multivitamin use and improved mood and mental well-being. This may be particularly relevant for individuals with suboptimal nutrient intake or those experiencing stress-related depletion of certain vitamins and minerals.

Promoting Cardiovascular Health

While evidence is mixed, some studies have found associations between long-term multivitamin use and a reduced risk of cardiovascular events, particularly in women.

Supporting Immune Function

Adequate intake of vitamins and minerals is crucial for maintaining a robust immune system. Multivitamins may help ensure that the body has the necessary nutrients to support optimal immune function.

Potential Risks and Considerations of Multivitamin Use

While multivitamins are generally considered safe for most people, there are some potential risks and considerations to keep in mind:

Interactions with Medications

Some vitamins and minerals can interact with certain medications, potentially altering their effectiveness or causing adverse effects. For example, vitamin K can interfere with blood-thinning medications, while calcium and iron supplements may reduce the absorption of some antibiotics.

Risk of Overconsumption

Taking multivitamins in addition to a nutrient-rich diet or alongside other supplements may lead to excessive intake of certain nutrients. This is particularly concerning for fat-soluble vitamins (A, D, E, and K), which can accumulate in the body and potentially reach toxic levels.

Quality and Regulation Concerns

The supplement industry is not as tightly regulated as the pharmaceutical industry. This means that the quality, purity, and potency of multivitamin products can vary significantly between brands. Choosing reputable brands and looking for third-party certifications can help mitigate this risk.

Potential for False Sense of Security

Some individuals may view multivitamins as a substitute for a healthy diet, potentially neglecting the importance of consuming a variety of whole foods. It’s crucial to remember that multivitamins should complement, not replace, a balanced diet.

Maximizing the Benefits of Multivitamin Supplementation

If you decide to take a multivitamin, consider the following tips to maximize its benefits and minimize potential risks:

Choose the Right Formulation

Select a multivitamin tailored to your age, gender, and life stage. For example, prenatal vitamins for pregnant women, or formulations designed for seniors that contain higher levels of certain nutrients like vitamin B12.

Timing Matters

Take your multivitamin at the optimal time for absorption. Many nutrients are best absorbed when taken with food, while others may be better absorbed on an empty stomach. Consult the product label or a healthcare professional for guidance.

Be Consistent

To reap the full benefits of multivitamin supplementation, consistency is key. Establish a routine that works for you and stick to it.

Monitor Your Overall Nutrient Intake

Keep track of the nutrients you’re getting from your diet and other supplements to avoid excessive intake. This is particularly important if you consume fortified foods or take additional individual supplements.

Regular Health Check-ups

Schedule regular check-ups with your healthcare provider to monitor your overall health and nutrient status. This can help identify any deficiencies or excesses and allow for adjustments to your supplementation regimen as needed.

The Future of Multivitamin Research and Personalized Nutrition

As our understanding of nutrition and individual variability grows, the field of multivitamin supplementation is likely to evolve. Several emerging trends and areas of research may shape the future of multivitamin use:

Nutrigenomics and Personalized Supplementation

Advances in genetic testing and nutrigenomics (the study of how genes interact with nutrients) may lead to more personalized multivitamin formulations. These tailored supplements could be designed to address an individual’s specific genetic predispositions and nutritional needs.

Improved Bioavailability and Delivery Systems

Ongoing research into nutrient absorption and delivery mechanisms may result in more effective multivitamin formulations. This could include the development of novel delivery systems that enhance nutrient bioavailability or targeted release technologies that optimize absorption in specific areas of the digestive tract.

Integration with Digital Health Technologies

The rise of digital health technologies, such as wearable devices and smartphone apps, may facilitate more accurate tracking of nutrient intake and nutritional status. This could lead to more precise and dynamic recommendations for multivitamin supplementation based on real-time data.

Focus on Synergistic Effects

Future research may delve deeper into the synergistic effects of various nutrients when consumed together. This could lead to the development of multivitamin formulations that optimize these beneficial interactions while minimizing potential antagonistic effects.

Exploration of Novel Nutrients

As our understanding of nutrition expands, researchers may identify new compounds with potential health benefits. These could be incorporated into future multivitamin formulations to provide a more comprehensive spectrum of nutritional support.

In conclusion, while the debate over the universal necessity of multivitamins continues, their potential benefits for certain populations and individuals with specific nutritional needs are well-established. As research progresses and our understanding of personalized nutrition deepens, the role of multivitamins in promoting health and preventing disease is likely to become increasingly nuanced and tailored to individual needs. Whether you choose to take a multivitamin or not, maintaining a balanced diet rich in fruits, vegetables, whole grains, and lean proteins remains the cornerstone of good nutrition and overall health.

Should I Take a Daily Multivitamin? | The Nutrition Source

Nearly half of adults in the U.S. and 70% of older adults ages 71+ take a vitamin; about one-third of them use a comprehensive multivitamin pill. [1] But is this truly a necessity?

There are certainly diseases caused by a lack of specific nutrients in the diet. Classic examples include scurvy (from a lack of vitamin C), beri-beri (vitamin B1), pellagra (vitamin B3), and rickets (vitamin D). But these conditions are rare in the U.S. and other developed countries where there is generally more access to a wide range of foods, some of which are fortified with vitamins. Individual vitamin supplementation may also be essential in certain cases, such as a deficiency caused by long-term poor nutrition or malabsorption caused by the body’s digestive system not functioning properly.

This page specifically discusses the use of multivitamins, which typically contain about 26 different vitamins and minerals, and often provide 100% of the Recommended Daily Allowance of these micronutrients. We will explore situations that a multivitamin may be health-promoting, as well as if there is a benefit or harm in taking extra nutrients from a pill if the diet is already adequate.

Who May be at Risk for a Nutrient Deficiency?

For those who eat a healthful diet, a multivitamin may have little or no benefit. A diet that includes plenty of fruits, vegetables, whole grains, good protein sources, and healthful fats should provide most of the nutrients needed for good health. But not everyone manages to eat a healthful diet. When it comes to specific vitamins and minerals, some Americans get less than adequate amounts, according to criteria set by the National Academy of Medicine. For example, more than 90% of Americans get less than the Estimated Average Requirement for vitamin D and vitamin E from food sources alone. [2]

Certain groups are at higher risk for a nutrient deficiency:

• Older age. The elderly are at risk for poor food intake for various reasons: difficulty chewing and swallowing food, experiencing unpleasant taste changes caused by multiple medications, or isolation and loneliness that can depress appetite. They also have trouble absorbing vitamin B12 from food. The National Academy of Medicine, in fact, recommends that people over the age of 50 eat foods fortified with vitamin B12 or take vitamin B12 pills that are better absorbed than from food sources. [3]
• Pregnancy. Getting enough folate, a B vitamin, is especially important for women who may become pregnant, since adequate folate can help lower the risk of having a baby with spina bifida or anencephaly. For the folate to be effective, it must be taken in the first few weeks of conception, often before a woman knows she is pregnant. Yet in the U.S., half of all pregnancies are unplanned. That’s why the Centers for Disease Control and Prevention recommend that all women of childbearing age (ages 15 to 45) consume 600 micrograms a day of folic acid. [3] This amount and other important nutrients for pregnancy—iron, calcium, vitamin D, and DHA—are available in a prenatal multivitamin.
• Malabsorption conditions. Any condition that interferes with normal digestion can increase the risk of poor absorption of one or several nutrients. Examples:
  • Diseases like celiac, ulcerative colitis, or cystic fibrosis.
  • Surgeries that remove parts of digestive organs such as having a gastric bypass for weight loss or a Whipple procedure that involves many digestive organs.
  • Illnesses that cause excess vomiting or diarrhea can prevent nutrients from being absorbed.
  • Alcoholism can prevent nutrients, including several B vitamins and vitamin C, from being absorbed.
• Certain medications. Some diuretics commonly prescribed to lower blood pressure can deplete the body’s stores of magnesium, potassium, and calcium. Proton pump inhibitors prescribed for acid reflux and heartburn can prevent the absorption of vitamin B12 and possibly calcium and magnesium. Levodopa and carbidopa prescribed for Parkinson’s disease can reduce the absorption of B vitamins including folate, B6, and B12.

A note on vitamin D

For most people, the best way to get enough vitamin D is taking a supplement because it is hard to get enough through food. Although some foods are fortified with vitamin D, few foods contain it naturally. Vitamin D supplements are available in two forms: vitamin D2 (“ergocalciferol” or pre-vitamin D) and vitamin D3 (“cholecalciferol”). Both are also naturally occurring forms that are produced in the presence of the sun’s ultraviolet-B (UVB) rays, but D2 is produced in plants and fungi and D3 in animals, including humans. Vitamin D production in the skin is the primary natural source of vitamin D, but many people have insufficient levels because they live in places where sunlight is limited in winter, or because they have limited sun exposure. Also, people with darker skin tend to have lower blood levels of vitamin D because the pigment (melanin) acts like a shade, reducing production of vitamin D.

Which Multivitamin Should I Choose?  

Multivitamins come in various forms (tablets, capsules, liquids, powders) and are packaged as a specific combination of nutrients (B-complex, calcium with vitamin D) or as a comprehensive multivitamin.  

Supplements are a multibillion-dollar industry, with endless designer labels of brands from which to choose. However, an expensive brand name is not necessary as even standard generic brands will deliver results. Look for one that contains the Recommended Daily Allowance amounts and that bears the United States Pharmacopeia (USP) seal of approval on the label. This seal ensures that the ingredients and amounts of that ingredient listed on the label are contained in the pill. The USP also runs several tests that confirm the pill to be free of contaminants like heavy metals and pesticides and has been manufactured under sanitary and regulated conditions. 

That said, you may wish to consider the following factors before starting a multivitamin or any supplemental vitamin. 

Reasons to use a multivitamin:

• I am eating a limited diet or my appetite is poor so that I am eating less than usual.
• I am following a restricted diet for longer than one week. This could be prescribed such as a liquid diet after a surgical procedure, or a self-imposed diet such as on with the goal of weight loss.
• I have a condition that reduces my body’s ability to absorb nutrients (celiac disease, ulcerative colitis) or have undergone surgery that interferes with the normal absorption of nutrients (gastric bypass surgery, Whipple procedure).
• I temporarily have increased nutrient needs, such as being pregnant.
• I’m very busy and just can’t eat a balanced diet every day.

Reasons that may not need a multivitamin:

• I eat well but am feeling tired all the time (discuss first with your doctor so they can investigate other possible causes).
• I eat a pretty good diet but want to improve my health as much as possible, so it couldn’t hurt to get some extra nutrition from a vitamin.
• I have osteoporosis and need more calcium, or I have iron-deficiency anemia and need more iron (in both scenarios, you may only need to take those individual nutrients rather than a comprehensive multivitamin).

If you are unsure about taking a multivitamin, you may wish to consult with a registered dietitian who can evaluate your current diet to determine any missing nutrients. At that time, suggestions to improve your food intake of those nutrients will be provided, or one or more supplemental vitamins may be prescribed if that is not possible. Always inform your doctor of all supplements you are taking in case of potential interactions with medications.   

Mega-doses (many times the Recommended Daily Allowance) of vitamins are not recommended. This can potentially interfere with the absorption of other nutrients or medications, or can even become toxic if too much is taken for a long period.  

Finally, be wary of supplemental vitamin labels that bait you with promises of “supporting brain health or energy production or healthy skin and hair.” These are general statements about a vitamin that are included for marketing purposes only, but are not specific to the supplement itself.  Also be wary of vitamins that contain extras, like herbs and botanicals, which are typically lacking in research about long-term effects and potential adverse effects. 

Multivitamins and Health 

Knowledge about the optimal intakes of vitamins and minerals to prevent chronic diseases is not set in stone. More long-term studies looking at this relationship are needed.   

There is no arguing that multivitamins are important when nutritional requirements are not met through diet alone. [4] The debate is whether vitamins are needed when the diet is adequate to prevent deficiency in nutrients, as some research has shown no benefit or even harmful effects when taking supplemental vitamins and minerals.  

• After a review of 26 clinical and cohort studies, the U.S. Preventive Services Task Force concluded there was insufficient evidence to support any benefits of multivitamins or individual vitamins for the primary prevention of cardiovascular disease or cancer among healthy, nutrient-sufficient adults. [5]  

For many diseases, but especially for cancer, only long-term trials are informative. The following studies looked at the effect of multivitamins on specific diseases and included healthy people as well as those with chronic diseases at the start of the study: 

Cancer

A randomized double-blind placebo-controlled trial provided a multivitamin or placebo to more than 14,000 male physicians, some with a history of cancer. After 11 years, the men taking a MVI had a significant 8% reduction in total cancers, compared with men taking a placebo. The results did not differ among men who had a history of cancer at the start of the study and men who were healthy at baseline. [6]

Cardiovascular disease

The Physicians’ Health Study II, a randomized double-blind placebo-controlled trial, provided a multivitamin or placebo to more than 14,000 male physicians, some with a history of cardiovascular disease. After 11 years, compared with the placebo, there was no significant effect of a daily MVI on cardiovascular events. [7]

Mortality

Some research has suggested that the rates of death appear higher in people using multivitamins. However, one major flaw in these studies was that many of the participants had already developed some type of serious illness. They may have started using vitamins after their health deteriorated, hoping for a benefit. But in those cases, taking a multivitamin might have been too late.

• The Iowa Women’s Health Study looked at the use of 15 vitamins and minerals, including multivitamins, at three different intervals and identified the numbers of women who died over a 19-year period. It showed that women over the age of 55 who took multivitamins were at higher risk for dying than those who did not. [8] A similar risk was found for other vitamins and minerals, including folate, vitamin B6, iron, magnesium, and zinc.
  • The Iowa study, however, didn’t exclude women who were sick or take into account how long they were using the vitamins. As a result, it is unknown whether the women were already taking vitamins when they became ill, or if they became ill and then started taking vitamins. In women who were already sick, taking vitamins was unlikely to lower their risk of dying.

The Bottom Line

It is important to remember that a multivitamin cannot in any way replace a healthful well-balanced diet. The main purpose of a multivitamin is to fill in nutritional gaps, and provides only a hint of the vast array of healthful nutrients and chemicals naturally found in food. It cannot offer fiber or the flavor and enjoyment of foods so key to an optimal diet. However, multivitamins can play an important role when nutritional requirements are not met through diet alone. When this is the case, an expensive brand name is not necessary, as even standard store brands will deliver results. Look for one that contains the Recommended Daily Allowance amounts and that bears the United States Pharmacopeia (USP) seal of approval on the label.

Medically reviewed by Drugs.com on Jan 12, 2023. Written by Cerner Multum.

What is a multivitamin?

Multivitamins are a combination of many different vitamins that are normally found in foods and other natural sources.

Multivitamins are used to provide vitamins that are not taken in through the diet. Multivitamins are also used to treat vitamin deficiencies (lack of vitamins) caused by illness, pregnancy, poor nutrition, digestive disorders, and many other conditions.

Multivitamins may also be used for purposes not listed in this medication guide.

Warnings

Seek emergency medical attention if you think you have used too much of multivitamins. An overdose of vitamins A, D, E, or K can cause serious or life-threatening side effects. Certain minerals contained in a multivitamin may also cause serious overdose symptoms if you take too much.

Before taking this medicine

Many vitamins can cause serious or life-threatening side effects if taken in large doses. Do not take more of this medicine than directed on the label or prescribed by your doctor.

Before you use multivitamins, tell your doctor about all your medical conditions and allergies.

Ask a doctor before using this medicine if you are pregnant or breastfeeding.

Your dose needs may be different during pregnancy. Some vitamins and minerals can harm an unborn baby if taken in large doses. You may need to use a prenatal vitamin specially formulated for pregnant women.

How should I take multivitamins?

Use exactly as directed on the label, or as prescribed by your doctor.

Never take more than the recommended dose of a multivitamin. Avoid taking more than one multivitamin product at the same time unless your doctor tells you to. Taking similar vitamin products together can result in a vitamin overdose or serious side effects.

Many multivitamin products also contain minerals such as calcium, iron, magnesium, potassium, and zinc. Minerals (especially taken in large doses) can cause side effects such as tooth staining, increased urination, stomach bleeding, uneven heart rate, confusion, and muscle weakness or limp feeling. Read the label of any multivitamin product you take to make sure you are aware of what it contains.

Take your multivitamin with a full glass of water.

You must chew the chewable tablet before you swallow it.

Place the sublingual tablet under your tongue and allow it to dissolve completely. Do not chew a sublingual tablet or swallow it whole.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Use multivitamins regularly to get the most benefit.

Store at room temperature away from moisture and heat. Do not freeze.

Store multivitamins in their original container. Storing multivitamins in a glass container can ruin the medication.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of vitamins A, D, E, or K can cause serious or life-threatening side effects. Certain minerals may also cause serious overdose symptoms if you take too much.

Overdose symptoms may include stomach pain, vomiting, diarrhea, constipation, loss of appetite, hair loss, peeling skin, tingly feeling in or around your mouth, changes in menstrual periods, weight loss, severe headache, muscle or joint pain, severe back pain, blood in your urine, pale skin, and easy bruising or bleeding.

What should I avoid while taking multivitamins?

Avoid taking more than one multivitamin product at the same time unless your doctor tells you to. Taking similar vitamin products together can result in a vitamin overdose or serious side effects.

Avoid the regular use of salt substitutes in your diet if your multivitamin contains potassium. If you are on a low-salt diet, ask your doctor before taking a vitamin or mineral supplement.

Do not take multivitamins with milk, other dairy products, calcium supplements, or antacids that contain calcium. Calcium may make it harder for your body to absorb certain ingredients of the multivitamin.

Multivitamins side effects

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

When taken as directed, multivitamins are not expected to cause serious side effects. Common side effects may include:

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect multivitamins?

Multivitamins can interact with certain medications, or affect how medications work in your body. Ask a doctor or pharmacist if it is safe for you to use multivitamins if you are also using:

• tretinoin or isotretinoin;

• an antacid;

• an antibiotic;

• a diuretic or “water pill”;

• heart or blood pressure medications;

Spring and well-being: why do we need multivitamins?

Brittle nails, burrs, faded skin, hair loss and depressed mood, we are accustomed to attribute to a lack of vitamins. “This is beriberi,” we say and sigh heavily, throwing handfuls of multi-colored vitamin capsules into ourselves. In fact, beriberi is not to blame for anything, few people are familiar with it at all.

Roskachestvo, together with Doctor of Medical Sciences, nutritionist, reflexologist Mariyat Mukhina, is seriously dealing with the issue of spring ailments.

Spring blues

In the spring, diseases are exacerbated. Tired of flu epidemics and cloudy days, the body asks for rest. In early spring, you especially want to sleep, people become lethargic, depression and apathy even come to someone. Meteorologically dependent suffer from pressure surges and headaches, aching joints and mood swings. Flashes in the sun provoke emotional outbursts, and weather changes – frequent colds.

It turns out that it’s not just about vitamins. Although their lack affects many processes inside the body.

Let’s get acquainted: vitamins

Vitaminoses can be divided into several types. Here are the main ones:

• Avitaminosis is a serious pathology in which one or more vitamins are not supplied to the body. It is very rare, in Russia among the peoples of the Far North, where the food is of the same type, and the diet is not balanced.

• Hypervitaminosis – an excess of vitamins, in which they are more than normal by 9-10 times. Moreover, we are talking about fat-soluble vitamins A, D, E, F and K. For example, in order to earn an excess of vitamin A, you need to eat 1.5 kg of carrots every day, and for quite a long time, or chew vitamin complexes instead of breakfast, lunch and dinner.

• Hypovitaminosis – lack of vitamins in the body. It occurs in 85% of the population, especially in people who eat processed foods, canned foods, fast food lovers living in ecologically disadvantaged areas.

The risk group also includes workers in hazardous industries, smokers, fans of “therapeutic” starvation and uncontrolled medication. Corrected by changing the diet. But to know for sure whether you have enough vitamins, you can only by a blood test.

If our poor health can be attributed to a lack of vitamins, then it is worth calling it hypovitaminosis. Here we’ll talk about it.

Vitamins are not enough only in spring?

If you forbid yourself to eat vegetables and fruits in the summer, then the sun, fresh air and a minimum of viruses will still help the body feel good. And, in comparison with summer well-being, spring seems terrible to us. By the way, things are no better in autumn and winter. You need to monitor your diet almost all year round.

Reference:

It is naive to believe that vegetables and fruits have all the necessary vitamins. In fact, they contain a sufficient amount of only folic acid, carotene and vitamin C. To get B vitamins, you need to eat wholemeal bread, bran, eggs, nuts, cereals, meat and dairy products

Is it worth it to overeat with “vitamins” from the garden in summer?

Fresh vegetables and fruits are needed all year round. Hoping that in the summer you can gain nutrients for the future, unfortunately, is useless.

It will be possible to stock up only with vitamins A, D and E, which are deposited in the fatty cells of the liver.

Vitamin B1 is stored in the body for 4 to 10 days.

B2 and B6, as well as vitamins C and K – about 1.5 months.

It turns out that until winter, and even more so until spring, summer stocks will not be preserved in any way. And the body itself can only produce vitamins D, PP and K, and even then a little.

Therefore, in the spring it is important to take a multivitamin for good health.

Is it possible to do without multivitamins?

It seems that with the current abundance of products in stores, this is not so difficult. You build a balanced diet, where there are products of different composition – and be healthy!

Each vitamin has its own daily requirement. We used to think that it is enough to eat an orange and a carrot a day to get the right amount of vitamin C and vitamin A. A piece of meat to replenish the reserves of vitamins B1 and B2 …

But we forget that, for example, 2-3 cups of coffee a day lead to the fact that thiamine (vitamin B1) is completely decomposed in the body. That during the heat treatment of the product, more than half of the vitamins are lost. After all, it is unlikely that most of you are able to eat three raw carrots every day.

It turns out that you can live without vitamin complexes in tablets, but who can withstand such a diet? Otherwise, we again come to hypovitaminosis.

So you need a multivitamin. They can be drunk for a long time, but, like any medication, multivitamins should be prescribed by a doctor, taking into account the region of residence, individual health characteristics, the amount of physical activity and the current composition of the blood.

Regular intake of properly selected multivitamins is reflected not only in the general well-being and freshness of the skin. About a third improves short-term memory, facilitates the course of many chronic diseases, even if taken 50% of the recommended dose.

Reference:

Remember, taking vitamin complexes will not make junk food healthy. Do you still eat chips and drink beer? Get a disturbed metabolism, obesity and other troubles.

You still need to keep an eye on your diet. If you really want to eat something forbidden and useless, you can afford it, of course. But only occasionally, otherwise no vitamins will help.

Why do we need multivitamins, if our ancestors got along just fine without them?

Many people have a natural question. For some reason, before people did not take any vitamin complexes and felt great, but now, even if you adhere to a healthy diet, you cannot do without multivitamins.

Indeed, vitamin intake rates have changed dramatically in the past 50 years for several reasons.

1. Environmental background. Now, going out on any street in a large city, we get more free radicals in 15 minutes than our grandparents in a lifetime. And to neutralize them, antioxidants are needed, which are vitamins.
2. Breeding of horticultural fruits and vegetables . It goes to the needs of the tastes of buyers towards an increase in sugars, sizes and a decrease in acid, which means a decrease in vitamins. When they say that before “the grass was greener, and the apples were tastier” – so it was! There are much fewer vitamins in greenhouse vegetables than in those grown in the summer in the garden.
3. Alcohol, smoking. Many people lead an unhealthy lifestyle – they smoke, drink … Nicotine and alcohol lead to the fact that the body loses useful substances at a catastrophic rate.

Reference:

By the way, our ancestors constantly used sauerkraut, pickled berries as a source of vitamins. These are fermented foods, in which, as a result of the activity of lactobacilli, the amount of vitamins increases several times.

However, along with taking a multivitamin, proper nutrition is very important.

Top 10 products that will allow you to cope with hypovitaminosis in the spring:

1. Sauerkraut
2. Carrot
3. Frozen blackcurrant
4. Frozen sea buckthorn
5. Fresh herbs
6. Honey
7. Nuts
8. Fish
9. Lean meat
10. Dairy products

Add them to your diet and be healthy!

Why take a multivitamin every day: doctors named 6 reasons

Why take a multivitamin every day: doctors named 6 reasons

Shared: Internet Publications

Other version

A multivitamin is a medical product that contains a group of vitamins designed for one dose. But after all, we consume the necessary nutrients with food, why else should we take synthetic ones every day?

In response to this, doctors name 6 reasons, especially highlighting vitamins for women.

Why vitamins from food are not enough

Yes, we get a lot of nutrients from fruits and vegetables, but not enough. Why is this happening? Medical studies have shown that 76% of adults do not eat enough fruits, and 87% of people do not eat enough vegetables. This is due to different eating habits, seasonality of products and not knowing which vitamin is contained in what. But this is not a sentence.

To make up for the deficiency, multivitamin complexes are needed, and that’s why we need them every day.

Beauty Maintenance

For women, vitamins are of particular importance. Vitamin B ₃ , C and biotin are needed for beautiful and thick hair; A, C, D improve skin quality, promote the production of natural collagen.

But one vitamin complex may not be enough if a woman has a history of problems with internal organs. For example, yellowing skin is not a signal from the body about beriberi, but that you should immediately pay attention to the liver.

Age changes

There is a process of natural aging of the body. With age, it becomes more difficult for him to absorb nutrients from food. Various factors are superimposed on this: stress, digestive problems, a limited diet. Multivitamins solve these problems by adding the right vitamins to the norm.

Heart Support

Taking multivitamins has a good effect on the heart – it needs B 9 for its normal functioning0177 1 , B ₂ , B ₆ , K ₁ , niacin (B ₃ ), CoQ10 and magnesium. There are special B-complexes that contain them.

While B vitamins are chemically distinct, they often work together in a variety of biochemical processes in the body, such as cellular energy production, healthy red blood cell synthesis, and neurological processes.
