Is Biotin Safe?

Biotin is not only safe, it is vital to overall health and in treating certain medical ailments, according to WebMD. Biotin supports a person's nerves, skin, digestive tract and cells. It also contributes to a healthy metabolism. Some research suggests that, in combination with other nutrients, biotin helps with diabetes.

Recommended daily intake levels of biotin vary by age and health conditions. Some people take more than the daily allowance for health purposes. While there may be risks for excessive doses, notes WebMD, they aren't clear as of 2014. Adequate biotin is typically found in a well-balanced diet, though some pregnant women take supplements.
