A 2006 review determined that collagen supplements improve joint function and substantially reduce painful osteoarthritis symptoms, explains Medical News Today. This research demonstrated that supplemental collagen hydrolysate provides pain relief benefits by activating joint chondrocytes to produce extracellular matrix and also increases collagen concentration in the cartilage. However, some research trials have not proven collagen supplements to provide these benefits.

A placebo-controlled, double-blind research study involving 69 women found that taking a collagen hydrolysate supplement improves skin health, reports National Institutes of Health. The skin elasticity and skin texture of women taking a daily dose of either 2.5 or 5 grams of supplemental collagen improved compared to a placebo group. Although not statistically significant results, improvements in level of skin moisture and the skin’s ability to remain hydrated were additional benefits noted in participants who took collagen supplements.

An animal study using rabbits demonstrated that supplemental collagen encourages the growth of collagen fibrils in the Achilles tendon and potentially improves tendon function, according to National Institutes of Health. This research suggests that hydrolyzed collagen supplements also offer benefits for the skin because both skin and tendons are predominantly composed of type 1 collagen.
