Frequently asked
Common questions.
Does collagen actually work?
Some evidence supports daily use over 6+ months. Effects are subtle but real.
Marine vs bovine?
Marine is closer to human collagen (better-absorbed). Bovine is cheaper. Both work.
How much collagen daily?
10-20g daily for clinical effect. Most under-dosed products are 2-5g.
