Does Collagen Count As Protein? Here's What You Should Know

There are plenty of reasons to focus on protein intake besides the most obvious muscle gain potential. See, protein plays a role in keeping your bones, skin, muscles, and even more essential body functions in their best shape. 

The short answer: not quite. "What makes proteins different is their amino acid content," registered dietitian Albert Matheny, R.D., CSCS, previously told mbg. "Collagen has a very different set of amino acids than a typical animal- or plant-based protein powder."

They provide very different benefits as well. So while protein powder may be helpful for muscle gains or staying full throughout the day, collagen can't exactly check those boxes. (Although, one small clinical study found those who took collagen daily while participating in an exercise program gained more muscle mass1 than those who only did the exercise program.)

What's more, collagen peptides support skin health, joint health, and bone health. In terms of the former, studies show that hydrolyzed collagen peptides are able to support skin elasticity and dermal collagen density2.

How? Well, hydrolyzed collagen peptides have been shown to help promote the body's natural production of collagen3, which makes them extra helpful in preventing wrinkles and sagging.
