1. Type of Collagen
Look for Type I & III hydrolysed bovine collagen. These types are highly bioavailable and support joint strength, skin elasticity, and muscular recovery. Marine vs Bovine shows why bovine remains the gold standard for men’s performance.
2. Protein Content
Aim for products offering at least 10g of collagen per serving. Many UK brands underdose — Revayo Prime delivers 14g of collagen plus Vitamin C to support real results, especially for active men.
3. Supporting Nutrients
Vitamin C is critical for collagen synthesis. Additional ingredients like zinc, hyaluronic acid, and biotin (found in Revayo Boost) enhance skin health, joint resilience, and overall absorption.
4. Clean Label & Quality
Opt for UK-made supplements that are non-GMO, free from artificial sweeteners, and third-party tested. Revayo is produced with strict quality standards and a clean formula you can trust.
5. Designed for Men
Collagen isn’t just for beauty. Men need joint protection, muscle recovery, and long-term mobility. Choose a product that’s formulated with these goals in mind — not just skin health. Our Prime + Boost Stack is built for exactly that.
