The Fundamentals of Collagen and Its Role in the Body
Collagen is the most abundant protein in the body, serving as a key structural component in various tissues, including skin. Despite its popularity, collagen supplements lack essential amino acids, specifically tryptophan, making them an incomplete protein source. When consumed, collagen does not get directly incorporated into new collagen in the body; studies show only small fragments of collagen may enter the bloodstream and potentially influence collagen deposition indirectly. This brings into question the effectiveness of collagen supplements, as they might not provide the expected benefits of boosting collagen levels in the skin.
