11 g hydrolyzed bovine per serving, Informed Protein certified, IGEN non-GMO tested. The best price per serving of the certified powders.
The obvious first choice for most people buying collagen: 11 g of hydrolyzed bovine type I and III per serving at roughly ninety cents, the lowest price of any third-party-tested powder we rank. Informed Protein verifies protein content, IGEN covers non-GMO, and the company publishes heavy-metal testing. The serving lands in the dose range of the trial literature (around 10 g per day in Clark 2008). If you want a tested, trial-relevant dose at the best price, buy this.
Hydrolyzed collagen is the rare supplement-aisle product with randomized human trials behind specific claims: a 2021 meta-analysis of 19 RCTs found improved skin hydration and elasticity after roughly 90 days, and a 24-week randomized trial reported less activity-related joint pain at 10 g per day. The effects are modest, many trials are industry-funded, and the hair, gut and weight claims on most tubs outrun the data. We grade the full evidence file in our collagen peptides review; the short version is that skin and active-joint endpoints are earned, the rest is marketing.
The published trials used 2.5 to 10 g daily for skin endpoints, 10 g for joint comfort, and 15 g in the muscle protocols paired with resistance training, taken for 8 to 24 weeks; nothing in the literature supports week-one effects. Timing is unstudied except for one pre-exercise protocol, so consistency beats clock-watching, and hot coffee does not degrade the peptides. Vitamin C is a genuine cofactor in collagen synthesis, so taking your scoop with a meal that includes some costs nothing. This is reported from the trials, not a prescription.
