What Does Collagen Do?

Vanessa Gibbs’ 20 August 2026 post explains collagen and promotes Blueprint Collagen Peptides. The article says collagen production falls about 1% per year after age 25 and lists possible roles in skin, joints, connective tissue, muscle recovery, bone, hair, and nails. It recommends a broad-spectrum product containing collagen Types I, II, and III, 20 g of protein, 0 g of sugar, and third-party testing. The page says Bryan Johnson takes the product every morning before and after his workout. It gives no dose beyond the 20 g product criterion, no duration, no comparator, no participant count, no standardized skin or joint endpoint, and no adverse-event table. The “study-level support” wording is not matched to identified studies on the page. The factual update is a new product-specific educational page and a stated routine. The article’s claims should not be read as evidence that this product improves skin, muscle, or bone outcomes. Collagen research is product- and endpoint-specific; a consumer explainer cannot substitute for a randomized trial. The page also includes the standard FDA disclaimer that the claims have not been evaluated for diagnosis, treatment, cure, or prevention of disease. This is a product communication with protocol-adjacent n=1 use, not a self-experiment report.
