Frequently Asked Questions

Does collagen actually work for skin or is it just hype?

Clinical evidence supports it. A 2019 meta-analysis of 11 RCTs (805 participants) found collagen peptides significantly improved skin hydration, elasticity, and wrinkles compared to placebo. Benefits appear within 4-8 weeks and increase with continued use. Look for hydrolyzed Type I collagen peptides at 5-10 g daily for best skin results.

What type of collagen should I take?

Type I and III (typically from bovine or marine sources) are best for skin, hair, nails, and tendons. Type II (undenatured, UC-II) at just 40 mg/day works differently — it modulates the immune response in joints and is specifically for joint health. For general wellness, hydrolyzed Type I & III peptides at 10-15 g daily cover most applications.

Should I take collagen with vitamin C?

Yes. Vitamin C is a required cofactor for collagen synthesis — without it, your body cannot properly incorporate collagen building blocks into new tissue. The Shaw et al. (2017) study showed that 15 g collagen + 50 mg vitamin C before exercise doubled collagen synthesis markers in tendons. Even for skin benefits, pairing collagen with at least 50-100 mg vitamin C is recommended.
