DOES IT WORK?
Good pick. Good evidence for skin and joint benefits at proper doses. Bovine collagen is rich in types I and III, which are the main structural proteins in skin, tendons, and bones. Multiple RCTs show improvements in skin hydration and elasticity at 2.5-10g daily. Joint benefits take longer but are real.
