Nutricost Creatine Monohydrate Powder vs Optimum Nutrition Micronized Creatine Monohydrate Powder
Both are plain micronized creatine monohydrate, so the choice comes down to price per serving and format. Nutricost sells 300 g, about 60 servings at 5 g, while Optimum Nutrition's 120-serving tub is roughly twice the size. Check the live price per serving on both before buying; the cheaper one per gram is the better buy, since the active ingredient is the same.

Questions and answers
- Which is better for a first-time creatine user?
- Nutricost's 300 g tub is the easier starting size at about 60 servings. If you already know you will stick with it, the 120-serving Optimum Nutrition tub costs less per serving.
- Do they work the same?
- Yes. Both are micronized creatine monohydrate at the standard 5 g dose. Strength and recovery effects come from the creatine itself, not the brand.
- Is the flavored Optimum Nutrition version worth it?
- Only if you dislike the taste of plain creatine in water. Unflavored powder mixes into juice or a shake with no taste at all, and usually costs less.
- Which lasts longer?
- Optimum Nutrition, at 120 servings versus about 60 for the 300 g Nutricost tub. At one 5 g serving a day, that is roughly four months versus two.
- Should I worry about the lead warning on the Nutricost listing?
- That is California's Proposition 65 warning, which appears on many supplement listings. If it concerns you, the Optimum Nutrition listing does not carry one.
