Vitamin C is required to build collagen.

Vitamin C is a required cofactor for the enzymes that cross-link collagen, so without enough of it your body cannot build collagen properly no matter how much you supplement. Pairing them supports skin, joints, tendons, and bone.

What to do

Take collagen (typically 10 to 15 g) together with vitamin C, either as a supplement or a vitamin-C-rich food. Consistent daily use over 8 to 12 weeks is what tends to show results in skin and joint studies.
