Consumer advice
If you want collagen, buy generic collagen peptides from Sports Research, Orgain, or Vital Proteins at $10-14 for the same quantity. The active ingredient (hydrolyzed collagen tripeptides) is identical across brands. If skin health is your goal, consistency matters more than brand—take 10g daily for 8+ weeks. Don't expect dramatic results; clinical trials show modest improvements in skin elasticity and hydration, not transformation. Check that any collagen product specifies 'hydrolyzed' or 'peptides' to ensure absorption.
