Collagen production declines roughly 1% per year starting in your mid-20s — and by midlife that loss shows up in skin elasticity, joint comfort, and hair density. A 12-week randomized controlled trial found that adults taking low-molecular-weight collagen peptides daily showed improved skin hydration, increased elasticity, and fewer wrinkles versus placebo, with gains building through weeks eight and twelve. Thorne's Collagen Plus delivers 13g of grass-fed, hormone-free type I and III collagen peptides alongside three supporting ingredients: HydroPeach® white peach ceramide extract, a patented MitoHeal® currant polyphenol blend, and nicotinamide riboside (NR), a direct NAD+ precursor that supports cellular repair from within. Thorne is the #1 recommended clinical brand by healthcare practitioners, based on the results of a 2023 survey, and partner to 100+ professional sports teams. Every product is third-party tested across a minimum of four rounds in an NSF International-approved, GMP-certified facility. The collagen peptide evidence here is solid. The NR-for-skin mechanism is promising but still largely preclinical — we recommend this product for the strength of its collagen formulation and Thorne's manufacturing standard.
