The Active Ingredient Is: Biotin (Vitamin B7)

Biotin is a water-soluble B vitamin involved in energy metabolism and in the synthesis of keratin, a protein important for hair and nails. This ingredient supports normal skin and hair health as part of its biological roles.

Biotin functions as a coenzyme in carboxylase reactions, aiding in the metabolism of fats, proteins and carbohydrates. It contributes to keratin production and to the maintenance of normal skin and hair, aligning with nutritional guidance on healthy integumentary function.

What Does Biotin Do?

Biotin participates in energy metabolism and keratin synthesis, which supports the structural integrity of hair and nails and overall vitality. These roles are described in high-level nutritional guidance as part of normal skin, hair and energy metabolism processes.

This formula also has included other ingredients to support biotin's role in healthy keratin and energy metabolism, enhancing overall nutrient function within normal body processes.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
