What It Actually Is
Biotin (vitamin B7) is a water-soluble vitamin essential for converting food — carbohydrates, fats, and proteins — into usable energy.
What Research Generally Shows
Biotin plays a role in glucose metabolism and has been studied in combination with chromium for blood sugar support in some research.
Why 1050% DV Isn't Alarming
Because biotin is water-soluble and has a wide margin of safety, supplements commonly include it at many multiples of the daily value — excess is generally excreted rather than stored.
