Consumer advice
If you want collagen for skin health, this product is reasonable—clinical trials support skin improvements at 2.5-10g daily. However, skip the joint, brain, and liver claims; those lack strong human evidence. You can save 50-70% by buying generic collagen peptides from Amazon or Costco. If you're taking this for anything other than skin, consider whether you actually need it. Third-party testing is a green flag, but don't let it override the fact that most claims are marketing hype."
