Ingredient
Collagen Peptides: Skin, Joint & Connective Tissue Support
Collagen is the most abundant protein in the human body, forming the scaffolding of skin, tendons, ligaments, and cartilage. Endogenous collagen synthesis drops sharply after age 30, and hydrolyzed collagen peptides provide the specific amino acid triads that stimulate fibroblast activity.
How oral collagen works
Hydrolyzed peptides (typically 2–10 kDa) survive digestion and reach circulation, where they signal fibroblasts to produce new collagen and hyaluronic acid. Bioactive di- and tri-peptides such as Pro-Hyp are the active messengers.
Skin, hair, and nail results
Randomized trials report improvements in skin elasticity (up to 15%), hydration, and reduced wrinkle depth after 8–12 weeks at 5–10 g daily. Hair thickness and nail growth also improve in most participants.
Joints, tendons, and bone
Studies in athletes show reduced joint pain and improved recovery when 10–15 g of collagen is taken 30–60 minutes pre-exercise, likely by concentrating amino acids at connective-tissue synthesis sites.

Frequently asked questions
How much collagen should I take?
5–10 g daily is the clinical range for skin outcomes. 10–15 g pre-exercise is used in joint and tendon research.
Does collagen actually work?
Yes — a growing body of double-blind trials confirms measurable improvements in skin elasticity, wrinkle depth, and joint comfort with 8–12 weeks of consistent use.
Marine vs bovine collagen?
Both are effective. Marine collagen (Type I) is highly bioavailable and favored for skin; bovine collagen (Types I and III) supports skin, joints, and gut lining.
