Collagen

What it does

Collagen is the most abundant protein in your body, the structural glue in skin, joints, and connective tissue, and we make less of it as we age. Hydrolyzed collagen is broken into small peptides that absorb easily and appear to signal the body to build more of its own. Meta-analyses show real improvements in skin hydration and elasticity over about 90 days.

The science

Most relevant for
