January 2012 in “Journal of nutrition & food sciences” This study found that a nutritional supplement containing peptides, lipids, hyaluronic acid, and collagen improved skin, hair, and nail dryness, with significant benefits noted for those with severe symptoms.
March 2024 in “Journal of functional foods” This study found that both marine and bovine collagen peptides may help prevent hair loss by supporting epithelial hair follicle stem cell functions, with marine peptides maintaining hair in the growth phase and bovine peptides increasing stem cell presence in hair follicle regions.
January 2017 in “OPAL (Open@LaTrobe) (La Trobe University)” This study found that oral collagen peptides increased the expression of genes related to epidermal and hair cycle development in hairless mouse skin.
This study found that oral collagen peptides increased expression of genes associated with epidermis development and the hair cycle in hairless mice, providing insights into their potential skin benefits.
This review reports that oral collagen peptide supplements may improve skin elasticity, hydration, and wrinkle appearance while also supporting hair and nail health and wound healing, but emphasizes the need for longer, high-quality studies due to current research limitations and variability in findings.
