Collagen is the predominant form of protein throughout the body. It’s part of connective tissues, bones, cartilage, and supports red blood cells and tissue integrity. With aging, the body’s production of collagen decreases which results in many health issues. Supplementing with collagen boosts the body’s metabolic processes and can help offset the decline in collagen due to aging. Collagen is the predominant form of protein throughout the body.
