Keratin is one of the most important structural proteins in the body and is an essential building block for hair, skin, and nails. Recent studies have shown that supplementing with keratin can help keep skin moisturized and smooth, encourage hair growth, and improve nail strength.*

Hair health

Participants ingesting keratin (500mg) plus vitamins and minerals, per day in a randomized, double-blind, placebo-controlled clinical trial experienced a significant improvement (46%) in hair fallout compared to baseline, 5.9% increase in hair strength, and a 47% improvement in appearance after 90 days. Overall, the keratin blend showed a 12.5% reduction in hair loss over placebo at Day 30 and a 34.5% and 34.4% reduction at Days 60 and 90, respectively (1).

Nail strength

Data from a randomized, double-blind, placebo-controlled trial giving healthy subjects an oral supplement of keratin (500mg) plus vitamins and minerals found that women taking keratin showed statistically significant improvement in all 5 parameters for nail health (breakage, strength, resistant, smoothness, color) at 90 days (1).

Skin moisture and elasticity

In a 90-day randomized, double-blind, placebo-controlled clinical trial, healthy subjects with visible signs of skin aging were given an oral supplement of 500mg solubilized keratin plus vitamins and minerals to assess the effects on skin parameters such as moisture, elasticity, wrinkles, protein content and appearance. Results showed significant improvements in skin moisture, skin elasticity, wrinkle reduction, skin compactness and skin appearance compared to placebo after 90 days. After 90 days, skin moisture was significantly increased by 11% with almost 80% of subjects taking keratin showing an increase in skin moisture. Skin elasticity also significantly increased after 90 days of supplementation, with participants showing a 7.2% improvement and 87% overall saw an increase in skin elasticity. Appearance of wrinkles were measured quantitatively and also qualitatively by a certified Dermatologist. Using a quantitative measure, wrinkle depth decreased by about 12% from baseline after 90 days, and the dermatologist evaluation showed a 58% improvement in the appearance of wrinkles after 90s of supplementation (1).
