Wool keratin as a novel alternative protein: A comprehensive review of extraction, purification, nutrition, safety, and food applications

“…Clinical trials also demonstrated that Cynatine R FLX1 (Beer et al, 2013b) and Cynatine R HNS (500 mg/day; Roxlor LLC, Delaware, USA; Beer et al, 2014) could supplement bioactive peptides and amino acids responsible for protecting and rebuilding damaged joints and improving the growth and strength of hair and nails. Other product claims include boosting body protein supply and promoting healing on injury or vigorous activity (Beer et al, 2013a(Beer et al, , 2014Kelly et al, 2007;. Wool-derived keratin hydrogels can accelerate wound healing by stimulating tissue regeneration (i.e., new capillaries and collagen synthesis) and hair follicle development (Moore et al, 2016).…”

“…Another study showed improvement in skin and nail health in a randomized 90‐day administration of Cynatine® (500 mg keratin/day) to 50 females ( n = 25 per group) compared with a placebo control group ( n = 25; Beer et al., 2013a). The oral ingestion of keratin tablets showed improved skin hydration, elasticity, wrinkle reduction and increased compactness.…”
