Insufficient

evidence for biotin

Our honest take

A low-cost vegan biotin capsule from Osavi, in three tub sizes. Adults need only about 40 µg of biotin a day and most diets provide it, and there is no good evidence that extra biotin improves hair or nails unless you are deficient. Biotin-only products are usually thousands of micrograms per capsule, and doses like that can distort some blood tests. We could not verify the dose, so check the label and tell your doctor you take it.

A health professional has told you that you are low in biotin
You want a vegan, low-cost biotin and understand the evidence for hair and nails is weak
You are hoping for thicker hair or stronger nails: the evidence does not support biotin for this unless you are deficient
You have blood tests coming up: tell your doctor, as biotin can distort thyroid, hormone and heart test results
You are pregnant or breastfeeding: check with your GP or midwife first

The science

Biotin· evidence: Insufficient

Biotin (vitamin B7) helps the body turn food into energy. Adults need only about 40 to 50 µg a day, and it is found in eggs, nuts, seeds, meat and many other foods. Deficiency is rare and is mostly seen with rare genetic conditions, long-term raw egg white intake or some medicines.

Biotin is heavily marketed for hair and nails. In people who are actually short of biotin, hair and skin problems improve when it is replaced. In healthy people who are not deficient, there is no good evidence that high-dose biotin makes hair grow faster or thicker, or nails stronger.

Most hair-and-nail products use 2,500 to 10,000 µg, which is 50 to 200 times the daily need. The body excretes the excess, so it is not known to be harmful, but you are paying for an amount you do not need.

Authorised health claim
Biotin contributes to normal energy-yielding metabolism. Biotin contributes to normal functioning of the nervous system. Biotin contributes to normal macronutrient metabolism. Biotin contributes to normal psychological function. Biotin contributes to the maintenance of normal hair. Biotin contributes to the maintenance of normal mucous membranes. Biotin contributes to the maintenance of normal skin. (Applies where a daily dose gives at least 15% of the NRV, i.e. 7.5 µg.)

Typical dose: Adults need about 40 µg a day (NRV on labels: 50 µg). Most diets provide this.

Safety: High-dose biotin can make some blood tests give false results, including thyroid tests and the troponin test used to diagnose heart attacks. Tell your doctor and the lab that you take biotin, and ask whether you should stop it for a few days before a blood test. The UK Expert Group on Vitamins and Minerals considered 970 µg a day from supplements unlikely to cause harm; there is limited safety data above that.
