Who would have thought that a substance found in bones and skin could become the need-to-have supplement? We’re talking collagen.
“Collagen is a type of protein that plays an important role in building and supporting many tissues, from bones and cartilage to skin, hair, eyes, and the digestive system,” says Sonya Angelone, RDN, who practices in San Francisco and is a spokesperson for the Academy of Nutrition and Dietetics.
When you take a collagen supplement or eat foods rich in collagen, you are consuming collagen that comes from an animal, explains Ryanne Lachman, RDN, a functional medicine dietitian at Cleveland Clinic in Ohio. Collagen peptides are often sold in powdered or capsule form, and collagen can also be consumed in bone broth.
As with any supplement, there are potential side effects.
