The most abundant protein in the human body, collagen is found in skin, joints, teeth and bones. When heat is applied to collagen, it can degrade and turn into gelatin. Gelatin has practically the same nutritional profile as collagen. Health wise, both can improve skin, joints, bones and the gut. Chemically, however, there are differences. This is why collagen dissolves in cold water and gelatin doesn’t, and also why cooled gelatin forms into a gel, and collagen doesn’t. In terms of usage, collagen is popular as a nutritional supplement, while gelatin is used in cooking.
- Collagen and gelatin supply nearly identical amounts of calories and protein, and have no carbs or fat.
- Both collagen and gelatin may limit signs of aging and reduce joint pain and stiffness.
- Unlike collagen, gelatin cannot dissolve in cold water, though it can turn into a gel.
