Dermatologist Dr. Michelle Henry has advised that a healthy, well-rounded diet is the best way to prevent the natural loss of collagen, but not immediately taking supplements. She suggests that superfoods, such as superfood, contain many of the same building blocks for collagen and antioxidants as supplements. Starting with food, Henry recommends starting with protein-rich foods, which also provide other nutritional benefits such as protecting collagen from oxidative stress. The best collagen-boosting foods include lean meats, eggs, Greek yogurt, fish, and bone broth. However, supplements contain marine collagen derived from fish or shellfish, which can cause reactions in some people with seafood allergies.
