What is the recommended dosage for Keratin?

General: 250-500 mg/day solubilized keratin

What are the side effects of Keratin?

Potential side effects include: Generally well-tolerated, Rare gastrointestinal discomfort.

What is keratin and how may it support skin and hair health?

Keratin is the primary structural protein in skin, hair, and nails. Solubilized keratin supplements (Cynatine HNS) have been studied in clinical trials showing improvements in hair strength, nail appearance, and skin smoothness. Keratin provides bioavailable amino acids including cysteine, essential for disulfide bonds in skin and hair.

What dosage of keratin has been studied for skin and hair benefits?

Clinical trials have used 500 mg of solubilized keratin (Cynatine HNS) per day for 90 days. Studies measured outcomes including skin moisture, elasticity, hair strength, and nail appearance. The evidence base is smaller compared to collagen peptides, with fewer independent RCTs available.

What are the potential side effects of keratin supplements?

Oral keratin supplements are generally well tolerated. Mild gastrointestinal discomfort has been reported. Individuals with allergies to wool or feathers should exercise caution, as some keratin supplements are derived from these sources. Formaldehyde, which is a concern in topical keratin hair treatments, is not present in oral supplements.

About

Keratin is a structural protein providing mechanical strength to hair, skin, and nails. Solubilized keratin supplements provide cysteine-rich peptides that may support endogenous keratin synthesis. A 90-day RCT found 500 mg/day of solubilized keratin improved skin moisture and elasticity, though the evidence base is limited.

How It Works

Structural protein providing mechanical strength to hair, skin, and nails; solubilized keratin supplements provide cysteine-rich peptides that may support endogenous keratin synthesis and disulfide bond formation in epidermal cells.
