Dietitian Sammi Brondo, MS, RD, adds that the protein can support bone health, as well as nail and hair growth.But as is true with all supplements, not all collagen is made equally. Dermatologist Michele J. Farber, MD, of Schweiger Dermatology Group, says that while more research is needed to substantiate the potential benefits of collagen supplement, some options are better than others.
