Oral collagen supplements are products that contain collagen, a protein that makes up a significant portion of our hair and connective tissues. These supplements are typically derived from animal sources such as bovine, porcine, or marine collagen, and are consumed in the form of pills, powders, or drinks. The idea behind taking oral collagen is that it can be broken down into amino acids in the digestive system, absorbed into the bloodstream, and then used by the body to support the structure and health of various tissues, including hair.

While some studies and anecdotal evidence suggest that oral collagen supplements may help improve hair health by promoting hair growth, thickness, and strength, the scientific support is not yet robust. Collagen provides the amino acids needed to produce keratin, the protein that makes up hair, which may explain potential benefits. However, more rigorous research is needed to conclusively determine its effectiveness. As for safety, oral collagen supplements are generally considered safe for most people, with few reported side effects. However, individuals with allergies to the source of collagen or those with specific health conditions should consult a healthcare provider before starting supplementation.
