Swanson Premium Brand Keratin delivers 50 mg of food-grade hydrolysed keratin per capsule, sourced from Tibetan wool. Keratin is a tough, fibrous structural protein that contains a notably high concentration of the amino acid cysteine — a sulphur-rich compound that forms strong molecular bonds known as cysteine bridges within connective tissue. Each bottle contains 60 capsules.
The keratin used in this formula is hydrolysed, meaning it has been broken down into a more readily absorbed form. Sourcing from Tibetan wool is considered by Swanson to be a marker of quality, and the product is manufactured to the brand’s Premium standards with a food-grade specification.
These capsules are well suited to those who prefer a straightforward, single-ingredient supplement — particularly people who already follow a multi-supplement routine and want to add keratin as a standalone addition. The unflavoured capsule format requires no mixing and is easy to take alongside food or drink.
