Specific collagen consumption, thanks to a precise ratio of amino acids (glycine, proline, hydroxyproline), could potentially slow biological aging and improve longevity.

The debate centers on a study suggesting that a specific ratio of amino acids derived from collagen extends lifespan in animal models and improves cellular markers. Current research, particularly on glycine alone, shows encouraging results for metabolic health and cellular aging (in animal models and in vitro studies). However, evidence in humans remains very limited and is often based on correlations. A critical point highlighted by the community is the significant conflict of interest of the authors, who are linked to the company marketing the studied product, which suggests caution. Furthermore, critics note the absence of protein-balanced control groups, making it difficult to distinguish between a specific effect of collagen and a simple increase in protein intake. The community is divided between enthusiasm for these new longevity markers and rigorous scientific skepticism regarding the methodology and the associated marketing.
