Collagen is made naturally in the body from amino acids. It is the most abundant structural protein in the body, found in connective tissues, bones, skin and tendons. However, as we get older, our collagen production starts to diminish. Animal products containing collagen or collagen supplements can help support joint health, skin elasticity and recovery times. They may also help to fight the signs of aging. Marine collagen in Australia is sourced from ocean-based origins, such as the skin and bones of fish. Some consider this a healthier alternative to collagen from cows or pigs. Fit Nutrition stocks a wide range of collagens to meet your requirements.
