Optimum Nutrition Creatine

“The creatine your gym bro swears by — turns out he's actually right for once.”

8/10Trust Score

76%Confidence

At ~$39.99 for a standard tub, ON Creatine runs about $0.66/serving — more than 3x the cost of Nutricost ($0.21/serving) and about double Sports Research ($0.31–$0.33/serving). You're paying for brand trust and wide availability, not a superior molecule. The underlying ingredient is identical across all creatine monohydrate products.

Why We Said BUY

Our analysis found Optimum Nutrition Creatine to be a genuinely solid product — creatine monohydrate is one of the most well-researched performance supplements on the planet, and ON delivers it cleanly at 5g per serving with no filler. It scores the highest rating (4.65/5) in a head-to-head comparison of 6 creatine products by Garage Gym Reviews. The main caveat: at ~$0.66/serving, you're paying a brand premium — budget options like Nutricost deliver the exact same molecule at ~$0.21/serving. If the ON name gives you peace of mind and the price doesn't sting, this is a BUY. If you're optimizing for pure cost-efficiency, the cheaper alternatives are doing the same job.
