The good and bad about biotin supplements (Vitamin B7)

New research has found that some cosmetic products can contain enough biotin to interfere with several laboratory test results, including those of thyroid function,

Study coauthor Saleh Aldasouqi, MD, of Michigan State University, told Medscape Medical News: “We know people take biotin as a hair product, a skin product, and as an energy supplement… The biotin dose found in vitamin supplements, about 50 µg, is roughly the daily requirement for the human body and doesn’t typically interfere with lab results. The problem comes with the far higher doses used in cosmetic products. The typical beauty tablet has 5 to 10 mg, so taken twice a day, that’s 10,000 µg. That is what would interfere with the labs.”

As a result, those using such products are advised to stop doing so for a week before laboratory tests are done.
