Here is the whole secret of this category, and the reason the ranking is tight: creatine monohydrate is the proven form, and it’s the cheapest. Decades of research use monohydrate; the “advanced” forms — HCl, buffered, ethyl ester — have never been shown to beat it, and usually cost more. Every product in this list is monohydrate. So none of them wins or loses on the molecule. They win or lose on whether the dose is a real 5 grams, whether an independent lab has actually checked the tub, and what you pay per gram of creatine. Our full reasoning is in the creatine explainer; this page applies it to what’s on the shelf.

Our picks
Best overall — Thorne Creatine
- A clean 5 g of monohydrate, single ingredient, nothing else
- NSF Certified for Sport — the gold-standard independent check, verified on the NSF database
- ~$0.49 a serving: premium, but you’re paying for the certification, not better creatine
Best value — Optimum Nutrition (or Nutricost if you want the cheapest)
- The same 5 g of pure monohydrate for roughly a quarter of the price (~$0.23, or ~$0.17 for Nutricost)
- ON carries Informed Choice banned-substance testing; Nutricost is a tested-claim budget champion at ~3–4¢ a gram
- If you don’t need NSF Certified for Sport, this is where the smart money goes
The field, ranked and honest
Thorne Creatine
If you want to remove all doubt about what’s in the tub, this is it. Thorne’s creatine is one plain ingredient — micronized monohydrate, 5 grams a scoop — and it’s NSF Certified for Sport, which we confirmed on the public NSF database rather than taking on faith. That certification tests the finished product for banned substances and label accuracy, and very few creatines carry it. The catch is price: at about $0.49 a serving it’s roughly double the mainstream options. You’re not getting better creatine for that — you’re getting the strongest independent guarantee that the creatine is clean, which for tested athletes (and the peace-of-mind buyer) is worth it. Nothing here is a red flag; it’s simply the premium done right.
Momentous Creatine
A near-twin of Thorne on the things that matter: a clean 5 g of monohydrate and NSF Certified for Sport, at essentially the same per-serving price. Momentous leans hard on purity marketing — screening for heavy metals, PFAS and microplastics — and as of mid-2026 it moved off the branded Creapure raw material to its own in-house “Signature Spec” standard. That’s the one thing to keep an eye on: “Signature Spec” purity is defined by the brand rather than by an outside standard the way Creapure is, so treat the glossier claims with mild skepticism. The NSF certification, though, is real and verifiable — which is what earns it a spot right behind Thorne. Heavy influencer promotion is doing some of the price-justifying work here.
Optimum Nutrition Micronized Creatine
The mainstream bestseller, and it earns the value crown: the identical 5 g of pure micronized monohydrate as the premium tubs, for about half the price a serving. It carries Informed Choice banned-substance testing — a legitimate batch program, though a step below NSF Certified for Sport — and the unflavored version is a single ingredient. The only nits are small: newer tubs ship without a scoop (an eco decision that annoys some buyers), and it’s not the gold-standard cert. For the overwhelming majority of people who just want proven, clean creatine without overpaying, this is the honest default. Between this and Thorne, you’re choosing whether NSF Certified for Sport is worth roughly $0.26 more per serving.
Nutricost Creatine Monohydrate
The budget champion, and genuinely good: a full 5 g of micronized monohydrate, no fillers, at roughly 3–4 cents per gram of creatine — the best value in the field by a wide margin. It’s made in a GMP-compliant, FDA-registered, NSF-registered facility and carries a generic third-party-tested claim. Read that carefully: an NSF-registered facility is not the same as the per-batch NSF Certified for Sport mark that Thorne and Momentous carry, and Nutricost doesn’t hold a named athlete certification — so competitive athletes who get drug-tested should step up to a certified option. There’s also a California Prop 65 lead notice, which is common for creatine and mineral powders. For everyone else watching their wallet, this delivers the exact same molecule as the top of the list for a fraction of the cost.
Create Creatine Gummies
The most interesting product here, and the clearest case of paying for format. Credit first: Create uses Creapure monohydrate and is NSF Certified for Sport — a serious certification that most gummies don’t bother with, plus an “anti-melting” formula aimed at the real concern that creatine can degrade in a gummy. But the math is unforgiving. Each serving is three gummies delivering 4.5 g, not the standard 5 g — a genuine under-dose — with about 2 g of added sugar, and it costs roughly six to eight times more per gram of creatine than powder. If chewing a gummy is the difference between taking creatine daily and forgetting, that convenience may be worth it, and the NSF certification means you’re at least getting a clean product. Just know exactly what the premium buys: less dose, more sugar, far higher cost — in a nicer wrapper.
Transparent Labs Creatine HMB
Transparent Labs has a strong “clean label” reputation, and the creatine itself is fine — a real 5 g of monohydrate. The problem is everything bolted onto it. This product adds 1.5 g of HMB, vitamin D3 and BioPerine and charges roughly $1.67 a serving — three to four times the value picks — on the strength of a “synergistic” formula. But HMB’s benefit in already-training lifters is weakly supported despite “clinically proven” language, so you’re paying a big premium for an extra whose evidence doesn’t hold up. And unlike the top of this list, the current product page claims only “third-party tested” with no named certification we could verify. If you specifically want an HMB stack and love the brand, fine — but as a way to buy creatine, it’s the most expensive route to the same 5 grams everyone else sells for far less.
How we scored them
Same 100-point rubric as every review on this site: formula and ingredient quality, dosage and label transparency, testing and manufacturing transparency, value per serving, product experience, and brand. In creatine that rubric rewards exactly what the science does — a real 5 g monohydrate dose, verifiable third-party testing, and a fair price — and penalizes under-dosing, unproven add-ons and paying a premium for the same molecule. Because monohydrate is settled science, good products cluster near the top and the separation is small and honest. Full method: how we review.
Frequently asked questions
What’s the best form of creatine?
Monohydrate — the most-studied and cheapest form. No “advanced” form (HCl, buffered, ethyl ester) has been shown to work better. Every product here is monohydrate; the differences are dose, testing and price.
How much should a serving have?
About 5 g a day for maintenance (studies use 3–5 g). Watch for gummies and capsules that deliver less — the gummy here provides 4.5 g. Check any product with our dose checker.
Is expensive creatine better?
Usually not. A budget monohydrate at ~3–4¢ a gram delivers the same 5 g as a premium tub. You pay more for NSF Certified for Sport or added ingredients — not for better creatine. Our cheapest pick scores within a few points of tubs costing four times more.
Do I need the NSF certification?
If you’re a drug-tested athlete, yes — choose Thorne, Momentous or the Create gummies, which carry NSF Certified for Sport. If you’re not, a well-made value monohydrate like Optimum Nutrition or Nutricost is the honest money-saver.
