Collagen supplements have become increasingly popular with their touted health benefits of improving skin health, alleviating joint pain, increasing muscle mass, and even promoting weight loss. But is there evidence to support these claims?
What is Collagen?
Collagen is the most abundant protein in the body. It is a structural protein naturally occurring within connective tissues, such as skin, bone, cartilage, and tendons. As you age, your body produces less collagen.
Collagen, like all proteins, is made from amino acids. Tryptophan is one amino acid that the body cannot produce; you have to get it from your diet. Since collagen does not contain the amino acid tryptophan, it is not considered a complete source of protein.
Collagen is found naturally in food sources such as bone broth, fish, egg whites, and spirulina. Eating foods high in vitamin C and zinc can help the body to produce collagen. Some dietary and lifestyle factors, such as high sugar intake and smoking, can damage your body’s collagen. In its whole form, collagen is not easily absorbed by the body. Many supplements contain collagen peptides which have been broken down to make them easier to digest.
