The Active Ingredient Is: Biotin

Biotin, a water-soluble B vitamin, is an essential nutrient involved in normal metabolic processes that support energy production and protein synthesis.

This formula features biotin as the sole active ingredient and uses vegetarian capsules with plant-derived excipients, consistent with vegan and non-GMO specifications.

What Does Biotin Do?

Biotin helps support normal protein metabolism and DNA activity through its role in biotinylation, a biochemical process important for cellular function. The nutrient functions within the body to maintain healthy maintenance of tissues and supports normal skin, hair and nails as part of a balanced diet.

Dr. Patel of University of Manchester found that biotin participates in biotinylation which is essential for protein metabolism, aligning with EFSA-supported roles for this vitamin.
