In the United States, biotin is promoted as a dietary supplement for strengthening hair and fingernails, though scientific data supporting these outcomes in humans are very weak. However, serum testing can be useful for confirmation of consumption of biotin-containing dietary supplements, and whether a period of refraining from supplement use is long enough to eliminate the potential for interfering with drug tests. When consumed as a biotin dietary supplement, absorption is nonsaturable, meaning that even very high amounts are absorbed effectively.
You should be able to get all the vitamin B6 you need from your daily diet. Pantothenic acid cannot be stored in the body, so you need it in your diet every day. Taking 40mg or less a day of riboflavin supplements is unlikely to cause any harm. Taking 100mg or less a day of thiamin supplements is unlikely to cause any harm. No evidence in humans has shown a toxicity of biotin even with high intakes.
Food sources
The dietary biotin intake in Western populations has been estimated to be in the range of 35 to 70 μg/day. For US food and dietary supplement labeling purposes, the amount in a serving is expressed as a percent of daily value. Biotin is obtained from foods, particularly meats and liver, and is sold as a dietary supplement. Different amounts may be recommended to treat vitamin B7 deficiency and will be advised by a proper health professional. Studies have shown that people consume on average 36 micrograms of biotin daily, meeting the average intake recommended above.
That’s why it’s important to discuss biotin supplementation with your doctor, especially if you have to undergo any clinical tests. For adults, the RDI is about 30 micrograms (mcg) of vitamin B7 per day. Supplements may be useful for individuals who struggle to meet their vitamin B7 requirement through diet alone.
In the US, biotin as a non-prescription dietary supplement is sold in amounts of 1 to 10 mg per serving, with claims for supporting hair and nail health, and as 300 mg per day as a possibly effective treatment for multiple sclerosis (see § Research). Anyone who has a deficiency can increase their biotin intake by consuming foods rich in the vitamin or taking biotin supplements. It is important to note that no evidence shows that biotin improves skin health in people who do not have a deficiency of the vitamin. In some cases, fortified foods and dietary supplements are useful when it is not possible to meet needs for one or more nutrients (for example, during specific life stages such as pregnancy). Dietary supplements that contain biotin are often promoted to improve the health of your hair, skin, and nails, but there is little scientific evidence to support these claims.
Does biotin interact with medications or other dietary supplements?
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.
Improves hair and nail health
The vitamin’s influence on the skin may stem from its effect on fat metabolism. Some people also believe that biotin may help improve psoriasis. This level of deficiency may affect a person’s health, but not enough to cause noticeable symptoms. Changing the diet and other lifestyle factors can help improve nail health, as can some commercial products.
Vitamin B7 can act as a coenzyme for certain amino acids — the building blocks of proteins — that help the body function properly.

Benefits and function
Also known as vitamin B7, biotin is a powerful compound that offers many health benefits beyond clearing your skin and helping your nails grow. Foods contain vitamins, minerals, dietary fiber, and other components that benefit health. However, supplements that contain biotin above recommended amounts may cause false results in some lab tests, including those that measure levels of certain hormones, like thyroid hormone.
