Cynatine HNS (Solubilized Keratin)
Also known as: Cynatine HNS, Cynatine, solubilized keratin, keratin peptides, bioactive keratin
Cynatine HNS is a branded, solubilized keratin produced from New Zealand sheep's wool by a patented process that keeps the protein bioavailable. Keratin is the structural protein of hair and nails, and the ingredient is marketed for hair strength, luster, and nail quality. A 90-day randomized, double-blind, placebo-controlled trial in 50 women taking 500 mg of Cynatine keratin per day, with vitamins and minerals, reported improvements in hair loss, strength, and nail measures compared with placebo.
Research summary
Supplies bioavailable keratin peptides and cysteine-rich amino acids as building blocks for hair and nail keratin.
Dosage
Daily amounts, of compound.
| Lowest studied | Typical range | Highest studied | Upper limit |
|---|---|---|---|
| 500 mg | 500 mg | 500 mg | — |
500 mg per day, taken as two capsules, is the studied dose. The trial formulation also included vitamins and minerals, so the keratin's stand-alone effect is not isolated. Benefits were assessed at 90 days.
Standardization: solubilized keratin (Cynatine brand)
Source material: sheep's wool keratin, solubilized
