Introduction to Collagen and Its Supplements
Collagen is the most abundant protein in the human body, making up approximately 25% to 35% of all proteins. It is a key component of connective tissue, providing strength, structure, and elasticity to skin, bones, tendons, and ligaments. As people age, their natural collagen production slows down, leading to wrinkles, joint pain, and other signs of aging. Collagen supplements, typically derived from animal sources such as bovine, marine, or porcine collagen, are marketed as a way to replenish collagen levels, thereby improving skin health, reducing joint pain, and supporting overall wellness.
How Collagen Supplements Are Metabolized
When collagen supplements are ingested, they are broken down into amino acids, which are then absorbed into the bloodstream. These amino acids can be used by the body to build new collagen or other proteins. The liver plays a crucial role in this process, as it is responsible for filtering the blood, metabolizing nutrients, and eliminating waste products. The kidneys also play a vital role, as they filter waste and excess fluids from the blood.
