Biotin is often added to multivitamins and hair/nail/skin supplements. An RDA (Recommended Dietary Allowance) does not exist for biotin because there is not enough evidence to suggest a daily amount needed by most healthy people. It is a water-soluble B vitamin found naturally in some foods and also in supplements. Results after 4–6 months from supplementing biotin at 20 mg/day into daily diet reduces the risk of lameness. A review of the fingernails literature reported brittle nail improvement as evidence from two pre-1990 clinical trials that had administered an oral dietary supplement of 2.5 mg/day for several months, without a placebo control comparison group.
Some evidence shows blood biotin levels may be lower in people with diabetes. A biotin deficiency may disrupt blood sugar, or glucose, regulation. That said, it is important to consult a healthcare professional before taking supplements during pregnancy or breastfeeding.
What happens if you don’t meet your daily vitamin B7 needs?
There is no established upper limit or toxic level for biotin. High doses have produced either falsely elevated or decreased blood levels, depending on the test. Between 1999 and 2016, the proportion of supplement users increased by nearly thirtyfold. Lactating women need 35 micrograms daily. Instead, there is an AI (Adequate Intake) level, which is assumed to ensure nutritional adequacy. Biotin plays a vital role in assisting enzymes to break down fats, carbohydrates, and proteins in food.

Since it is water-soluble, excess amounts are not stored in the body and are instead flushed out through the urine. Moreover, so far no research has shown the possibility of overdosing on vitamin B7. Some amount of vitamin B7 can also be synthesized by the bacteria living in the gut. Since biotin is an important factor in the synthesis of glucose, it may help maintain an appropriate blood sugar level in patients suffering from type 2 diabetes. It is suggested that biotin aids cell growth and the maintenance of mucous membranes. It acts as a coenzyme in a number of metabolic pathways involving fatty acids and essential amino acids, as well as in gluconeogenesis – the synthesis of glucose from non-carbohydrates.

The enzyme dethiobiotin synthetase catalyzes the formation of the ureido ring via a DAPA carbamate activated with ATP, creating dethiobiotin with the help of the enzyme, BioD, which is then converted into biotin which is catalyzed by BioB. KAPA is transported from plant peroxisomes to mitochondria where it is converted to 7,8-diaminopelargonic acid (DAPA) with the help of the enzyme, BioA. Bacteria also synthesize biotin, and it is thought that bacteria resident in the large intestine may synthesize biotin that is absorbed and utilized by the host organism. In pregnancy, this may be due to a possible acceleration of biotin catabolism, whereas, in lactation, the higher demand has yet to be elucidated. Relatively low levels of biotin have also been reported in the urine or plasma of patients who have had a partial gastrectomy or have other causes of achlorhydria, as well as burn patients, elderly individuals, and athletes. Intestinal biotin uptake also appears to be sensitive to the effect of the anti-epilepsy drugs carbamazepine and primidone.
Metabolic function relies on the conversion of glucose (sugar) from carbohydrates and fatty acids into energy. Vitamin B7 has been linked to the production of stronger keratin molecules, which can help strengthen hair and nails. When the skin barrier is strong, your risk of developing skin conditions like acne or eczema is also lower. These components are essential for maintaining a strong skin barrier — the outer layer of your skin that guards against environmental damage.

For profound deficiency, treatment is oral dosing with 5 to 20 mg per day. It is also important in freeing biotin from dietary protein-bound biotin. Urinary excretion of this compound is an early and sensitive indicator of biotin deficiency. Subclinical deficiency can cause mild symptoms, such as hair thinning, brittle fingernails, or skin rash, typically on the face. SMVT also binds pantothenic acid, so high intakes of either of these vitamins can interfere with the transport of the other. The large intestine microbiota synthesizes amounts of biotin estimated to be similar to the amount taken in the diet, and a significant portion of this biotin exists in the free (protein-unbound) form and, thus, is available for absorption.
It is also known as vitamin B-7 or vitamin H, in which case the H stands for “Haar und Haut,” the German words for “hair and skin.” Discover how vitamin E affects your health and learn to manage your intake to properly care for your health. Discover which supplements can support women during menopause, from evidence-backed options like soy and omega-3s to those still being studied for their efficacy. However, extremely high doses of vitamin B7 may interfere with some medical procedures — such as lab tests, leading to incorrect results. Elderly individuals should speak to their healthcare provider about an adequate intake of vitamin B7 for their circumstances.
Factors that affect biotin requirements
Studies have shown that people with MS respond positively to daily biotin doses of up to 300 milligrams (mg). This process is important for maintaining healthy skin, and it may be impaired in people with low levels of biotin. Researchers have also studied how biotin supplements affect blood sugar levels in people with type 2 diabetes.
Symptoms of deficiency
Lifelong treatment with supplemental biotin is recommended for both profound and partial biotinidase deficiency. For biotin labeling purposes, 100% of the daily value was 300 μg/day, but as of May 27, 2016, it was revised to 30 μg/day to agree with the adequate intake. Biotin (also known as vitamin B7) is one of the B vitamins – a group of essential dietary micronutrients. Like all of the 8 B vitamins, biotin is necessary for the body to convert food into glucose, which is used to produce energy. According to the Mayo Clinic, a daily intake of biotin of up to 10 milligrams has no adverse effects to the body.
However, since biotin deficiency is rare and the amounts needed by the body are small, many countries do not actually provide a recommended daily intake of biotin. Biotin is known to promote cell growth and is often a component of dietary supplements used for strengthening hair and nails, as well as those marketed for skin care.

It’s also easy to add eggs to your diet, enjoying them as a breakfast food or nutrient-rich addition to salads. Vitamin B7 plays a significant role in maintaining the health of your skin by supporting the production of fatty acids, amino acids, and fat metabolism..}
In a few small studies, some people with thin and brittle nails who took high doses of biotin had harder nails. Symptoms of biotin deficiency in infants include weak muscle tone, sluggishness, and delayed development. If you take vitamin B12 supplements, do not take too much as this could be harmful. But as vitamin B12 is not found naturally in foods such as fruit, vegetables and grains, vegans may not get enough of it.
