Biotin; Vitamin H (Biotin)

Although there is no evidence that biotin interacts with any medication, there are some medications that may deplete biotin levels. If you are being treated with any of the following medications, you should not use biotin without first talking to your health care provider.

Antibiotics
— Long-term antibiotic use may lower biotin levels by destroying the bacteria in the gut that produces biotin.

Anticonvulsant Medications
— Long-term use of anticonvulsant medications can reduce the body’s stores of biotin. Valproic acid can cause biotinidase deficiency, which may be helped by biotin supplements. Anticonvulsant medications include:

What is biotin?

Biotin is a form of vitamin B found in foods. Biotin helps the body break down fats, carbohydrates, and proteins.

Biotin has been used in alternative medicine as a likely effective aid in treating or preventing biotin deficiency. Biotin deficiency can be caused by malnutrition, rapid weight loss, long-term tube feeding, and other medical conditions.

Biotin has also been used to treat seborrhea (skin rash) in babies. However, research has shown that biotin may not be effective in treating this condition.

Other uses not proven with research have included treating brittle nails or thinning hair, diabetes, nerve pain, and other conditions.

It is not certain whether biotin is effective in treating any medical condition. Medicinal use of this product has not been approved by the FDA. Biotin should not be used in place of medication prescribed for you by your doctor.

Biotin is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

Biotin may also be used for purposes not listed in this product guide.

Learn about the importance of Biotin B7 in the human body and how to take it correctly. Tips and advice from experts in the article on our website.

Vitamins and minerals are essential elements for the life of the human body. Biotin b7, also known as vitamin H or coenzyme R, is one such essential nutrient. This vitamin is key for the proper metabolism of carbohydrates, fats and proteins, as well as the protection of skin, hair and nails.

Unfortunately, like many other vitamins, our body cannot produce it on its own. As a result, it must be obtained from external sources such as food or additional intake of natural or synthetic drugs. However, as with any vitamin, you need to know how to properly take biotin b7 for best results.

In this article, we will talk about the important role that biotin b7 plays in the human body and how to take it correctly to get the most benefit from this vitamin.

The role of biotin b7 in human health

Functions of biotin b7 in the human body

Biotin b7 is an essential B vitamin that plays a key role in the metabolism of carbohydrates, proteins and fats. It is necessary for the correct functioning of several enzymes, including adenosine triphosphate, which regulate the conversion of food into energy.

Biotin b7 also helps improve skin, hair and nail health by supporting cell regeneration and maintaining the health of keratin, the protein that forms the basis of skin, hair and nails. It also plays an important role in fetal development as it helps regulate the production and use of glucose in both mother and baby.

Intakes for biotin b7

The optimal level of biotin b7 intake for a healthy person is between 30 and 100 micrograms per day. Although deficiency of this vitamin is rare, people who consume large amounts of raw egg protein foods may need additional doses. Also, people with digestive disorders, such as chronic diarrhea or malabsorption disorders, may need large doses of biotin b7.

How to take biotin b7 correctly

Biotin b7 can be obtained exclusively through food or as a supplement to food. It is perfectly absorbed by the body, and therefore does not require special conditions for its intake. In order to get enough biotin b7, it is recommended to consume foods such as eggs, meat, oatmeal, peas, peanuts, onions, mushrooms, whole grain bread, seeds and nuts. If you think you may need an extra serving of this vitamin, talk to your doctor, who may recommend an additional food supplement.

Importance of biotin b7 for the human body

Biotin b7 is a vitamin that the human body needs for the proper functioning of cells and metabolic processes. It is involved in the formation of structural components of cells, such as keratin, the main protein in hair, nails and skin, and generates energy in the body. Biotin b7 is also necessary for the formation of glucose and the synthesis of fatty acids necessary for the functioning of the nervous system.

Biotin b7 can be obtained from foods such as eggs, animal organs, fish and nuts, but some people may be deficient in this vitamin. Inadequate intake of b7 biotin can lead to nail, hair, and skin problems such as brittle nails, hair loss, and skin rashes. Also, a deficiency of biotin b7 can lead to digestive and nervous system problems.

If biotin b7 is deficient, it is recommended to increase its intake through food or supplements. However, it should be remembered that excess biotin b7 can also be harmful to the body, so it is important to follow the instructions for taking the dosage, and it is better to consult a doctor or nutritionist.

Where is biotin b7 found in nature?

Biotin B7 is a B-vitamin found primarily in plant foods. These foods include green vegetables such as spinach or broccoli, as well as nuts, seeds, and grains, including rice, wheat, and oats.

Biotin is also found in various types of meat products such as chicken, beef and pork. Fish like mackerel and salmon also contain biotin.

In addition, biotin can be obtained from other sources. For example, biotin is often added to various vitamin complexes and dietary supplements, and is also used as a food additive to improve the quality of food.

• Spinach
• Nuts and seeds
• Cereals
• Chicken, beef and pork
• Mackerel and salmon

It is recommended to obtain biotin from natural sources, but in case of deficiency, it can be additionally taken in the form of special supplements. In any case, it is always recommended to consult your doctor before starting dietary supplements.

Biotin b7 indications

Healthy hair, skin and nails

Biotin b7 plays an important role in the formation of keratin, the main component of hair, skin and nails. With a lack of biotin, baldness can occur, dryness and irritation of the skin will appear, hair can become brittle and dull, and nails can become brittle and easily broken.

Biotin, aka vitamin B7: benefit to the body or harm?

Biotin (vitamin H, B7, coenzyme R, coenzyme R) is one of the B vitamins that performs many functions in the body. This compound is part of the enzymes that regulate the metabolism of proteins, fats and carbohydrates, is a source of sulfur necessary for the synthesis of collagen, participates in the activation and transfer of CO ₂ . Biotin is necessary for the nervous system and beneficial intestinal microflora, and is also important for the health of hair, nails and skin, which is why it was called the “beauty vitamin”.

The name of the compound comes from the ancient Greek word “biotos”, which means “life”. Vitamin b7 is produced by the intestinal microflora, but it does not accumulate well in the body. It needs a lot of magnesium to be absorbed. In addition, biotin metabolism is inhibited by saccharin, raw egg protein (avidin), foods with preservatives E221 – E228, cooked oils, alcohol, antibiotics, drugs containing sulfur, etc.

Health benefits of biotin

Vitamin biotin is necessary for the metabolism of fats, carbohydrates and proteins, is a coenzyme for enzymes from the lyase class, is involved in the synthesis of amino acids (isoleucine and valine) and fatty acids, as well as in the production of glucose.

Vitamin H is important for healthy nails, hair and skin. Deficiency of this compound has been linked to seborrheic dermatitis and red, scaly skin rashes. It is necessary for pregnant and lactating women, both for themselves and for the fetus: animal studies have shown that its deficiency during pregnancy can cause birth defects in offspring.

Due to its ability to reduce glucose levels, vitamin B7 is useful for diabetics. Some placebo-controlled studies have shown that glucose concentrations in people with type 2 diabetes are significantly lower with sufficient amounts of biotin in the blood. A study of this topic has shown the ability of the vitamin to prevent kidney damage in people with insulin-dependent type 1 diabetes.

The beneficial effect of high doses of coenzyme in the treatment of progressive multiple sclerosis has been experimentally proven.

Daily value for the body

The recommended daily dose of biotin, in principle, does not exist, since there is no exact evidence to establish its amount in the body. However, the American National Academy of Medicine (IOM) considers an adequate intake of 30 to 100 micrograms per day for adolescents and adults 19 years of age and older.

Most people can take biotin supplements in sufficient doses, and few report mild side effects such as nausea and digestive problems. Since biotin is soluble in water, the excess amount will leave the body during urination.

Who needs biotin

Biotin is a “native” substance for the body. With a good microflora, intestinal bacteria are able to produce it in more than sufficient quantities. In addition, it is available in a wide range of foods, so deficiency is not common in humans. However, with irrational nutrition, certain diseases, genetic characteristics, disturbed intestinal microflora, as well as alcohol abuse, which prevents the absorption of vitamins, there may be a lack of coenzyme R.

Additional intake of vitamin B7 may be required in the following cases:

Pregnancy . During this period, a woman needs an increased intake of all vitamins. Deficiency of the h vitamin can lead to abnormal fetal development. Doctors recommend taking 30 micrograms of biotin per day in addition to folic acid.

Type 1 and 2 diabetes . Research published in 2016 showed that vitamin B7 may help with glycemic control in people with diabetes by lowering blood glucose levels. Animal experiments have shown that it stimulates insulin secretion from the pancreas and subsequently lowers blood glucose levels. The results are promising, but more research is needed before a definitive effect of biotin on blood sugar levels can be confirmed.

Biotinidase deficiency . Another cause of vitamin H deficiency is an autosomal recessive metabolic disorder. In people with this disease, the body does not produce enough of the enzyme needed to release biotin from proteins in the diet during digestion or due to normal protein metabolism in the cell. Profound or partial biotinidase deficiency occurs in 1 in 60,000 newborns when the enzymatic activity is between 10% and 30%.

Control of neuropathy . Vitamin B7 supplementation may help reduce nerve damage in people on dialysis for kidney disease. In 1990, scientists found that three patients who took a large dose of biotin for 1-2 years improved their symptoms. Vitamin H is essential for pyruvate carboxylase activity, without which high levels of pyruvate and aspartate can occur, negatively affecting the functioning of the nervous system. However, further evidence is needed to confirm this.

R assay sclerosis . Studies have shown that treatment with high doses of vitamin B7 can help improve symptoms in people with multiple sclerosis, an autoimmune disease that affects the nervous system and leads to muscle weakness and a range of other problems.

Results published in 2016 showed that biotin is a safe therapy. In some participants, a high dose taken three times a day improved symptoms after 9months of use.

Skin, hair, nails . Statistics say that about 20% of the world’s population suffers from brittle nails. An experiment was conducted in which 35 people with brittle nails received 2.5 mg of biotin per day for 1.5–7 months, after which 67% of the participants had a 25% increase in the thickness of the nail plate and a significant decrease in brittle nails. There is also evidence that vitamin H can improve nail strength and longevity, and improve hair and skin health.

Research published in 2015 showed that women with thinning hair experienced some reduction in shedding after taking an oral marine protein supplement with biotin for 90 days. However, the US Office of Dietary Supplements (ODS) considers there is insufficient evidence that biotin supplements can strengthen nails and promote healthy hair.

In addition to these cases, biotin deficiency can occur in patients on long-term intravenous feeding, in infants who consume breast milk with a low biotin content, in patients with impaired absorption of the vitamin due to inflammatory bowel disease, dysbacteriosis and other disorders of the gastrointestinal tract as well as in smokers and those taking epilepsy medications such as phenobarbital, phenytoin, or carbamazepine.

The effects of long-term deficiency of biotin vitamin may be manifested by the following symptoms:

• increased cholesterol and blood sugar levels;
• general weakness, fatigue, deterioration in general well-being;
• rapid hair loss and alopecia;
• scaly red rash around the eyes, nose, mouth and genitals;
• hallucinations and seizures;
• numbness and tingling sensation in arms and legs;
• loss of control of body movements, known as ataxia;
• immunosuppression;
• frequent bacterial and fungal infections;
• certain types of liver disease.

Skin and hair benefits

Studies show that increasing your biotin intake can improve overall hair quality, including body and shine. Taking biotin supplements also helps for their growth.

Vitamin B7 deficiency is expressed by the following symptoms in relation to hair and skin:

• dull appearance and hair loss;
• poor complexion, dry and flaky skin;
• red rash around eyes, nose, mouth.

“Beauty Vitamin” saturates hair follicles with sulfur, which normalizes the functioning of the sebaceous glands, provides elasticity and silkiness to curls, and effectively fights seborrhea.

The effect of vitamin H on hair is expressed as follows:

• supporting red blood cells, provide hair follicles with oxygen;
• stimulating insulin metabolism, contributes to the saturation of each bulb with glucose;
• maintains the balance of keratin for hair elasticity, and the ability to withstand negative environmental influences.

In order to determine the benefits of vitamin B7 for hair, studies were conducted in which 30 women took biotin for three months, and a second company of the same number took a placebo. The structure of the hair in all women was damaged due to stress, poor diet, hormonal problems, etc. After a course of biotin supplements, there was a noticeable improvement in the condition of the hair in women in the first group, while nothing changed in the placebo group.

Thus, all the studies known today confirm the effectiveness of biotin for hair, which is recommended to be obtained from food or nutritional supplements.

Benefits for women

As a “beauty vitamin”, coenzyme R is beneficial for women. It improves the structure of the skin, heals the hair and strengthens the nail plate. Sometimes there may be a deficiency of this element during pregnancy and lactation. This is especially true if a woman experiences toxicosis of pregnant women, in which all vitamins are absorbed very poorly. However, in order not to harm the fetus, the additional intake of biotin supplements during pregnancy must be agreed with the doctor.

Vitamins with biotin for women helps to maintain normal weight, as it takes part in the breakdown of fats. In addition, it maintains stable blood sugar levels, which is important during pregnancy and breastfeeding. Sugar also plays an important role in normalizing the emotional state of a woman. It is known that the female body accumulates sugar by about 25% less than the male. A rapid drop in glucose leads to irritability, depression, reduced performance and sleep problems.

Deficiency in children

Congenital deficiency of the biotinidase enzyme is quite rare, affecting only one in 20-40,000 newborns and is detected by special screening.

Testing is indicated for symptoms such as seizures, hearing and vision loss, skin problems, hair loss or absence (alopecia), and frequent infections. Usually, the diagnosis is made between the ages of 1 and 6 months. The appointment of biotin preparations brings everything back to normal, however, in order to prevent mental retardation, treatment should be started as early as possible. Late therapy may resolve skin and hair problems, but may not affect neurological changes. Reception of biotin in this case is necessary throughout life. World Health Organization recommends inclusion of biotinidase deficiency test in newborn screening

Nutritionists and physicians recommend getting all vitamins and minerals from natural sources in the most absorbable form. Fortunately, vitamin b7 is found in varying doses in many foods. Otherwise, they can be obtained from vitamin complexes.

Anyone who regularly consumes tomatoes, eggs, spinach, nuts, cauliflower, legumes and organ meats may not be afraid to face a biotin deficiency. However, it must be taken into account that food processing leads to a decrease in the activity and effectiveness of vitamin B7.

How to take it right

Deficiency of coenzyme R in the body can be replenished in two ways: by eating foods rich in this compound, and by taking special biotin supplements. Consider the cumulative effect of receiving a connection. Taking the supplement daily, noticeable improvements occur around the 60th to 90th day from the start of the intake.

Vitamin H preparations available without a prescription. They very rarely cause side effects, which are expressed by nausea, diarrhea, stomach cramps. Before buying, you should consult a doctor who will inform you about potential risks, give advice on choosing a manufacturer brand and doses.

Be aware that biotin supplements can interact with certain drugs that are broken down by the liver, including clozapine (Closaril), haloperidol (Haldol), olanzapine (Zyprexa), etc.

How much to drink and how to drink

There is no consensus on the daily requirement of the body for vitamin B7. With the right diet, a person receives about 40 mcg of it with food. Additional intake depends on many factors (age, gender, weight, purpose of intake, lifestyle) and ranges from 50 to 300 mcg.

Pregnant and lactating women need a higher dose, but before buying the drug, you should consult your doctor.

Recommended doses depend on age and are:

• up to 3 years: 10-20 mcg,
• from 4 to 6 years: 25 mcg,
• from 6 to 10 years: 30 mcg,

9000 5 from 10 years and for adults: 30 – 100 mcg.

In congenital biotinidase deficiency, the initial dose is 5 to 10 micrograms per day.

Dosage of b7 vitamin for hair health:

• for support in winter or after hair coloring, no more than 1000 mcg per day.
• for dryness and brittleness, to stimulate growth – up to 5000 mgc per day.
• at the first signs of baldness, skin diseases – at least 10,000 mcg per day.

Vitamin b7 is available in the form of capsules and tablets, and less often a course of injections can be prescribed. You need to take (drink) biotin for at least 1 month, for hair treatment – at least 3 months, simultaneously with meals or immediately before meals, drinking plenty of water. It is important to understand that for a visible effect, especially in the treatment of hair, it will take time. In the case of treatment, the duration of the course and dosage should preferably be agreed with the attending physician.

Side effects

Biotin is considered a safe vitamin, it is easily excreted from the body in urine and feces, however, taking it much higher than normal can cause some side effects in the form of rashes and nausea. In order to avoid individual intolerance, it is worth consulting with your doctor before buying dietary supplements.

It is undesirable to combine vitamin B7 intake with anticonvulsants, as they reduce the bioavailability of the coenzyme. If such treatment is necessary, it is worth diluting the medication and biotin for different times.

Contraindications

Consumption of food rich in biotin does not pose a significant threat to the body. Large doses of biotin have no known toxic effects, but certain medications, herbs, and supplements may interact.

Abnormal indicators are low levels of vitamins C and B6, high blood sugar levels, and reduced insulin production.
