Buying Guide: What to Look For
Hydrolysed collagen peptides absorb better than gelatin. Marine collagen is best for skin (Type I), bovine for joints and gut (Types I and III). Always take with vitamin C to support collagen synthesis. Minimum effective dose is around 5g daily, with 10-15g optimal. Results take 4-12 weeks of consistent use.
Frequently Asked Questions
Does collagen supplementation actually work?
Yes. Multiple studies show hydrolysed collagen peptides improve skin elasticity, reduce wrinkles, and support joint health. Results are typically visible after 4-8 weeks of daily use at 5-15g.
Which type of collagen is best?
Type I (from marine or bovine) is best for skin, hair, and nails. Type II is best for cartilage and joint health. Type III supports gut lining and blood vessels. Many supplements combine types.
Can vegans take collagen?
Traditional collagen comes from animal sources. Vegan collagen boosters contain vitamin C, silica, and amino acids that support your body own collagen production, but they are not actual collagen.
