Collagen is the most abundant protein in the human body, found in muscles, bones, skin, blood vessels, tendons, and the digestive system. It acts as the "glue" that helps hold the body together, providing structure, strength, and elasticity to connective tissues. Collagen production naturally declines with age, which can lead to wrinkles, joint discomfort, and other signs of aging. Supplementing with collagen can help support the body's structural integrity and promote overall health and wellness.
