Biotin is the formula’s primary active for hair and nail support. It is a required cofactor for carboxylase enzymes involved in keratin protein synthesis, the structural protein that forms both hair and nails. At 5,000 mcg, this delivers the dose most commonly used in hair and nail support studies.*

Iron deficiency is one of the most common nutritional causes of hair thinning in women. Ferrous fumarate is a well-absorbed iron form that supports red blood cell production and oxygen delivery to hair follicles, which are among the most metabolically active cells in the body. See iron overdose warning below.*

This B-vitamin and Vitamin C matrix supports the cellular machinery of hair growth: Vitamin C supports collagen synthesis and iron absorption; Folate and B12 support red blood cell production and cell division in hair follicles; B6 is involved in amino acid metabolism relevant to keratin production; Pantothenic Acid at 30 mg (600% DV) supports the energy production pathways that fuel rapid cell turnover.*

Zinc at 7 mg (64% DV) supports sebum regulation, wound healing, and the inhibition of hair follicle regression. Manganese at 4 mg (174% DV) as amino acid chelate supports connective tissue formation. Magnesium and Potassium contribute to cellular hydration and enzymatic function across the skin and hair follicle environment.*
