Keratin is the structural protein of hair and nails, and in supplements it is used as a solubilized or hydrolyzed keratin so it can be formulated and absorbed. It is a hair-and-nail active often paired with biotin and collagen. Because supplement keratin is animal-sourced, it is not vegan, which shapes the product’s claims. HBM manufactures keratin into gummies and liquid formats in Tampa Bay, FL, formulating around the branded or generic keratin the brand specifies.

Solubilized and hydrolyzed forms

Raw keratin is insoluble, so supplement keratin is processed into a solubilized or hydrolyzed form that disperses and absorbs. Branded solubilized keratin ingredients carry their own studied dose and spec, while generic hydrolyzed keratin is a lower-cost option. HBM formulates around the form and brand the customer specifies and confirms it against the incoming COA.

Sourcing and claims

Supplement keratin is animal-sourced, typically from wool, so a keratin product is not vegan and that shapes the label and positioning. It does fit vegetarian and other clean-label claims depending on the full formula. HBM flags these constraints at pilot batch so the label claims match the actual formula.

Beauty-from-within stacks and formats

Keratin is usually stacked with biotin, collagen, zinc, and vitamin C in a hair, skin, and nail formula. It carries a modest dose, often around 500 mg of a solubilized keratin, which fits a gummy or a liquid. HBM makes it at a gummy MOQ of 300,000 units and a liquid MOQ of 3,000 units or 150L, with the flavor built around the full stack.
