Collagen is a protein that your body makes and uses to form vital structures like skin, bones, muscles and tendons. Collagen production drops off as you get older, leading to various age-related issues like wrinkled skin, decreased flexibility, joint pain and thinning hair.
The most reliable way to replenish your body's collagen supply is through the foods you eat. Yet, taking dietary supplements can also boost your body's collagen availability. Collagen supplements are sold in multiple forms, including powders, liquids, pills and gummies.
