Keratin is the fibrous structural protein that forms the foundation of your hair, the outer layer of your skin and the hard matrix of your nails. Producing keratin requires substantial metabolic energy, and B-complex vitamins are central to that energy supply.
Keratin synthesis demands amino acids (particularly cysteine), ATP energy and functional enzymes. B-vitamins serve as coenzymes in the metabolic pathways that generate all three. Without adequate B-vitamin supply, keratin production slows.
Biotin (B7) at 5000mcg: the most direct connection. Biotin serves as a cofactor for carboxylase enzymes involved in amino acid metabolism essential for keratin assembly.
B6 at 2mg: involved in over 100 enzyme reactions including the amino acid conversions that feed keratin synthesis.
B12 at 6mcg: supports DNA synthesis required for the rapid cell division in hair follicles and nail beds.
Folate at 442mcg DFE: works with B12 in DNA synthesis and cell division.
Pantothenic Acid at 5.2mg: powers coenzyme A production, essential for fatty acid metabolism that maintains skin barrier lipids.
B-vitamins work synergistically. Taking biotin alone without adequate B6, B12 and folate is like running one cylinder of a five-cylinder engine. Our formula includes all five relevant B-vitamins at disclosed doses so the full metabolic pathway functions efficiently.
