Collagen
Types & Sources
Collagen comes in multiple types: Type I (skin, bones, tendons), Type II (cartilage, joints), Type III (skin, blood vessels). Hydrolyzed collagen peptides absorb best. Bovine collagen (grass-fed) provides Types I & III. Marine collagen (wild-caught fish) offers Type I with smaller peptides for better absorption. Chicken collagen provides Type II for joint health. Take with Vitamin C for optimal synthesis.
