4. Supports Hair and Nail Health

Collagen doesn’t just benefit the skin—studies show it also plays a significant role in strengthening hair and nails. Research published in the Journal of Drugs in Dermatology indicates that collagen supplementation can reduce nail brittleness and improve hair growth.
Compared to popular supplements like biotin, collagen offers comprehensive structural support because it is a primary building block for keratin, the protein found in hair and nails. Experts suggest collagen as a holistic alternative or complement to biotin, making it a go-to for those seeking healthier, more resilient hair and nails.
