                                Collagen, the body's most abundant protein, naturally has a half-life of 30-60 days but can be much longer depending on the tissue and various external factors. The duration of collagen's benefits, particularly from supplements, is a common question, and the answer depends on whether you're considering the short-term presence of peptides or the long-term biological effects.
