The Best Creatine Supplements (2026): Five Tested Monohydrates Compared

The best creatine is plain creatine monohydrate, 3 to 5 g per serving, from a brand that has its product checked by an independent lab. That's it. Every other form, blend and flavor costs more without working better (Antonio et al., 2021).

Our top pick is Thorne Creatine: 5 g of micronized monohydrate, NSF Certified for Sport, at under 50 cents a serving. If you'd rather spend half that, Optimum Nutrition Micronized Creatine is the same monohydrate used in the research, with lighter testing.

How we chose

Every product here passed the same four checks, in this order. You can read the full method in how we choose products.

1. Form and dose. Creatine monohydrate only, with a full 3–5 g in one serving. That's the form and dose behind almost all the research. See the best form of creatine for why.
2. Independent testing. Supplements aren't checked by regulators before they go on sale. We favored products in the NSF Certified for Sport or Informed Sport databases, where an outside lab tests for label accuracy, contaminants and substances banned in sport.
3. Price per 5 g serving. Not per tub, which hides how many servings you get.
4. Nothing extra. No proprietary blends, added stimulants or "fat-burning" ingredients.

We didn't rank on taste or mixing. Plain monohydrate tastes of almost nothing, and the differences in how it dissolves are small. We haven't lab-tested these products ourselves; the testing we rely on comes from the certification programs, whose databases you can search.

Prices were checked in October 2026 and change often. Check the current price before you buy. We last checked every product's certification against the brand's own page and the certifier's listings on 1 November 2026.

Comparison table

All five are unflavored creatine monohydrate with 5 g per serving.

Which one should you buy?

If you want one answer: Thorne. NSF Certified for Sport, for around 50 cents a day, and stocked in stores as well as online. It doesn't work better than cheaper monohydrate, but you know exactly what's in the tub.

If Thorne is out of stock or Momentous is cheaper that day: Momentous is also NSF certified. It relaunched in June 2026 as "Signature Spec", made to its own specification instead of from Creapure.

If you compete in a drug-tested sport: buy only NSF Certified for Sport or Informed Sport products, and check the exact product and lot number on the certifier's website. Thorne, Momentous and Klean all have NSF Certified for Sport. Your federation may specify which certification it accepts.

If price matters most: Optimum Nutrition or NOW. Both are the same monohydrate used in the research, at roughly half the price of the certified picks. You're giving up batch-level independent testing, not effectiveness.

If you want to buy in a store: Thorne is widely stocked.

If you're trying creatine for the first time: Klean Athlete's smaller tub costs less up front, so you're not committing to a big tub before you know you'll stick with it.

If you're a woman: the same picks apply. Creatine sold "for women" is almost always the same monohydrate at a higher price. Our best creatine for women guide covers that in detail.

If you're vegetarian or vegan: creatine monohydrate is made synthetically, not from animal products. Vegetarians often notice the biggest effect, because a plant-based diet supplies almost no creatine. See creatine for vegetarians and vegans.

What we'd skip

A 30-second label check

Whatever you buy, turn the tub around and check:

1. The ingredient line says "creatine monohydrate" and nothing else, or close to it.
2. A serving is 3–5 g of creatine. Some scoops hold less than you'd expect.
3. There's a certification seal you can look up: NSF Certified for Sport, Informed Sport or USP Verified. "Made in a GMP facility" is about the factory, not the product.
4. No proprietary blend. If the amounts aren't listed, skip it.

Our creatine checker runs through these questions for any tub and gives you a verdict, and the label glossary explains every term you'll see.

How to take it

3 to 5 g a day, every day, at whatever time you'll remember. A loading phase is optional. Our creatine calculator works out your dose and how long your tub will last, and our dosage guide covers timing, mixing and missed days.

Questions people ask

What is the best creatine to buy?

Plain creatine monohydrate with independent testing. Our top pick is Thorne Creatine; Optimum Nutrition Micronized is the best value.

Is expensive creatine better?

No. Pricier products may have stronger testing or Creapure raw material, but monohydrate works the same whichever brand makes it.

Is creatine HCl better than monohydrate?

No. It dissolves better but hasn't worked better in head-to-head trials, and it costs more per gram.
