Overview
Thorne's Collagen Fit is an unflavored powder combining 15g of collagen peptides with 14g of protein per serving, plus nicotinamide riboside, in a 17.8 oz tub good for 30 servings. It carries NSF Certified for Sport status, a third party screen for banned substances.
Thorne has built its reputation on supplements tested to that NSF Certified for Sport standard, which matters specifically to competitive athletes who must avoid contaminated products. Being unflavored keeps it neutral for mixing into coffee, smoothies or other recipes instead of locking buyers into one taste.
