As it naturally occurs, collagen acts as a kind of scaffolding that keeps our faces looking nice and plump. But collagen production naturally declines as we age, slowly robbing us of these perks. The good news is, supplementing with collagen helps support this process.
Animal research has found that consuming marine collagen helps maintain dermal thickness by promoting the number and activity of skin fibroblasts, or cells in the dermis that produce collagen and other fibers.
In one study, women who took a supplement containing hydrolyzed Type I collagen derived from tilapia had better supported skin with diminished appearance of lines, photo-aging, and better maintained moisture levels.*
Marine collagen contains Types I collagen. Type I collagen, specifically, is found all over the body and is most highly concentrated in bone, ligaments, tendons, skin, hair, nails, and the gut lining.
