Consumer advice
If you want collagen peptides for skin health, this product will work—but you're likely overpaying. Buy a basic collagen peptide powder from Vital Proteins or a generic brand for 50-70% less. If you're interested in nicotinamide riboside or betaine, buy them separately at therapeutic doses (250mg+ NR, 6-10g betaine) rather than relying on the token amounts here. The practitioner-gated distribution doesn't add value—it's just a sales channel. Ask Fullscript or Thorne for the actual retail price before committing, and compare it to Amazon or iHerb prices for equivalent collagen products.
