Overview

Sports Research Collagen Peptides 41oz provides 11g of hydrolyzed collagen peptides (Types I & III) per scoop from grass-fed, pasture-raised bovine sources. The 41oz bulk tub provides 56 servings — nearly double the standard 16oz container. The hydrolyzed peptides dissolve easily in hot or cold liquids without gelling, making them versatile for coffee, smoothies, soups, and baking. Types I and III collagen are the primary structural proteins in skin (80% of skin collagen is Type I), hair, nails, bones, tendons, and ligaments. Clinical studies show 10g+ daily collagen supplementation improves skin elasticity, reduces wrinkles, and supports joint comfort within 8-12 weeks.
