Overview
Biotin, with a clear purpose. Biotin Max delivers one active ingredient in a focused formula. Best known for its role in hair and skin health, biotin also helps enzymes process fats, amino acids, and carbohydrates. That makes it important for energy metabolism and normal nervous system function, too.

This EFSA scientific opinion evaluates biotin's physiological functions and provides the basis for European health claims relating to healthy hair and skin, normal nervous system function, and energy and macronutrient metabolism. It connects the biological evidence with claims that can be communicated accurately to consumers.

A crossover study in healthy adults compared oral and intravenous biotin at several doses, including amounts well above typical dietary intake. Results indicated very high bioavailability of orally administered free biotin, even at higher amounts. The study examined biotin as an ingredient and showed that it is efficiently absorbed through the digestive tract.

People with brittle nails received 2.5 mg of biotin daily, the same amount provided by one capsule of Biotin Max. In the group assessed before and after supplementation, nail plate thickness increased by an average of 25%, and microscopy showed a more regular structure. The study examined biotin as an ingredient, not the finished Doctor Life product.
