B7 · HIGH-DOSE
Biotin,
at clinical strength.
5,000 mcg of D-Biotin per capsule — the B-vitamin that drives carboxylase enzymes behind fatty acid, amino acid, and glucose metabolism. Structural support for hair, skin, and nails follows the same chemistry.

The form that works.
D-Biotin is the biologically active stereoisomer — the form your carboxylase enzymes actually use. Clinical-level dosing supports macronutrient metabolism and keratin-dependent tissue turnover.
A cofactor, not a fad.
Biotin is the required cofactor for five carboxylase enzymes that sit at the junction of carbohydrate, fat, and amino-acid metabolism. Low biotin quietly disrupts all three pathways at once.
Simple, steady, specific.
One capsule with a meal. Biotin is water-soluble and well-tolerated, making it easy to layer into a methylation or hair-and-skin protocol without stacking bulk on the rest of the regimen.
MAY BENEFIT
One cofactor,
many pathways.
Formula
One vitamin. Clinical dose. No filler story.
