Best Creatine Supplements, Reviewed
Thorne Creatine
Best for: buyers who want a clean-label, third-party-tested monohydrate with no unnecessary extras.
Thorne is a supplement brand that regularly works with professional sports teams and the U.S. military supply chain, and its creatine reflects that trust profile: no fillers, no artificial additives, just micronized creatine monohydrate.
- Type: Creatine monohydrate (micronized)
- Dose per serving: 5g
- Servings per container: 90 (also sold in 30- and 180-serving sizes)
- Price: approximately $36–44
- Price per serving: approximately $0.40–0.49
- Flavors: Unflavored
- Third-party tested: NSF Certified for Sport (tested against 290 banned substances)
- Rating: not independently verifiable at time of writing; strong repeat-purchase reputation across major retailers
Thorne earns the overall pick because it hits every box a first-time or repeat buyer cares about: a well-studied form, a real third-party certification, a large 90-serving container, and a price per serving that stays competitive with far less rigorously tested brands.
Transparent Labs Creatine HMB
Best for: lifters who want a monohydrate base plus HMB for extra muscle-preservation support during a cut or intense training block.
Transparent Labs built its reputation on fully disclosed label panels with no proprietary blends, and the Creatine HMB formula adds 1.5g of HMB (beta-hydroxy beta-methylbutyrate) and vitamin D3 to the standard 5g creatine monohydrate dose.
- Type: Creatine monohydrate + HMB
- Dose per serving: 5g creatine monohydrate + 1.5g HMB
- Servings per container: 30 or 60, depending on size purchased
- Price: $49.99 for the 30-serving size
- Price per serving: approximately $1.50–1.67
- Flavors: Unflavored
- Third-party tested: Informed-Sport certified
- Rating: not independently verifiable at time of writing; consistently placed among premium-tier picks by third-party reviewers
Expect to pay the most per serving on this list here. That premium buys the HMB and BioPerine addition, not the base creatine itself, so if you only want plain monohydrate, a cheaper option below covers the same core job.
Momentous Creatine Monohydrate
Best for: competitive or drug-tested athletes who want Creapure-sourced creatine with an extra layer of contaminant screening.
The Signature Spec line is built specifically for professional and collegiate athletes. Beyond the standard NSF Certified for Sport banned-substance screen, Momentous states it independently tests for PFAS, heavy metals, and microplastics.
- Type: Creatine monohydrate (Creapure-sourced)
- Dose per serving: 5g
- Servings per container: 90
- Price: approximately $36.90–42.99 (tub), or $22.99 for a 15-serving travel-pack box
- Price per serving: approximately $0.41–0.48
- Flavors: Unflavored
- Third-party tested: NSF Certified for Sport, plus brand-stated PFAS/heavy-metal/microplastic screening
- Rating: not independently verifiable at time of writing
Price and certification put Momentous and Thorne in a near tie. What separates them is sourcing: Momentous uses Creapure-branded creatine specifically, a detail some buyers treat as a purity shorthand.
Klean Athlete Klean Creatine
Best for: athletes in drug-tested sports who want a straightforward, no-frills NSF Certified for Sport monohydrate.
Klean Athlete is the sports-nutrition line from Douglas Laboratories, built around a clean-label promise: no artificial flavors, sweeteners, or unnecessary additives, and every product carries NSF Certified for Sport status.
- Type: Creatine monohydrate
- Dose per serving: 5g
- Servings per container: not disclosed in sourced listings (11.1 oz container)
- Price per serving: approximately $0.50–0.58
- Flavors: Unflavored
- Third-party tested: NSF Certified for Sport
- Rating: not independently verifiable at time of writing
Klean Creatine costs a bit more per serving than Thorne or Momentous, but it is a long-standing option in the NSF Certified for Sport category and is widely stocked by retailers that specialize in athlete-safe supplements.
Naked Nutrition Creatine Monohydrate
Best for: buyers who want a large, affordable container of plain, third-party-tested monohydrate with minimal ingredients.
Naked Nutrition’s positioning is in the brand name: no additives, no artificial sweeteners, and no proprietary blends, just creatine monohydrate powder in bulk sizes.
- Type: Creatine monohydrate
- Dose per serving: 5g
- Servings per container: 100 (500g size); also sold in a 200-serving 1kg size
- Price: $21.99 (100-serving size)
- Price per serving: approximately $0.22
- Flavors: Unflavored
- Third-party tested: NSF Certified
- Rating: not independently verifiable at time of writing
This is one of the best value plays on the list: a genuinely low price per serving without giving up third-party testing, which is not always true of budget creatine.
BulkSupplements Creatine Monohydrate
Best for: buyers who train heavy and want the lowest possible cost per gram, and are comfortable with a brand that does not publish third-party sport-banned-substance testing.
BulkSupplements sells raw and lightly processed ingredients in bulk, and creatine monohydrate is one of its best-known SKUs, sold from 500g up to 5kg sizes.
- Type: Creatine monohydrate (micronized)
- Dose per serving: 5g
- Servings per container: 100 (500g) or 200 (1kg), larger bulk sizes also available
- Price: varies by size purchased
- Price per serving: approximately $0.20–0.35 depending on size and any subscription discount
- Flavors: Unflavored
- Third-party tested: not disclosed on sourced listings
- Rating: not independently verifiable at time of writing
If price per gram is the only thing that matters and you are not competing in a drug-tested sport, this is typically the cheapest way to get pharmaceutical-grade-labeled creatine monohydrate in bulk.
NOW Sports Creatine Monohydrate
Best for: buyers who prefer a long-established supplement brand widely available at pharmacies and health food stores.
NOW Foods has manufactured supplements since the 1960s, and its Sports line includes both a standard creatine monohydrate powder and an Informed-Sport certified version for athletes who need that assurance.
- Type: Creatine monohydrate
- Dose per serving: 5g (1.5 level teaspoons)
- Servings per container: approximately 45 per NOW’s own label on the 2.2 lb size (figure as labeled by the brand; not independently recalculated)
- Price: approximately $45.99–64.99 depending on size and retailer
- Price per serving: not calculated here, since sourced serving counts were inconsistent across NOW’s own container sizes
- Flavors: Unflavored
- Third-party tested: Informed-Sport certified version available
- Rating: not independently verifiable at time of writing
NOW is a reasonable pick if you already trust the brand from other supplement categories, though it is not the sharpest price-per-serving value on this list.
What Is the Best Type of Creatine?
Creatine monohydrate is the best type of creatine for most people. It is the form used in the overwhelming majority of clinical research, and every product on this list is built around it. Other forms exist, including creatine HCl, buffered creatine, and creatine ethyl ester, and brands market them on claims like better solubility or less bloating. None of those alternative forms has research support that matches monohydrate for muscle strength, power output, or high-intensity exercise performance, which is why every reviewed pick above uses monohydrate as its base, sometimes combined with an added ingredient like HMB.
How Much Creatine Should You Take?
The standard maintenance dose is 3 to 5 grams of creatine monohydrate per day, taken consistently. Some people use an optional loading phase to saturate muscle creatine stores faster.
- Loading phase (optional): 20g per day, split into 4 doses of 5g, for 5 to 7 days
- Maintenance phase: 3–5g per day, taken any time of day, with or without food
- Consistency matters more than timing: daily use is what drives the strength and power benefits, not the specific time of day you take it
Skipping the loading phase and going straight to a 3-5g daily maintenance dose still reaches full muscle saturation. It just takes a few weeks longer. If powder texture or mixing is a dealbreaker for you, our creatine gummies vs. powder comparison covers the dosing tradeoffs of chewable formats.
Is Creatine Safe to Take Every Day?
Yes, for most healthy adults. Creatine monohydrate has one of the longest safety track records of any sports supplement, with decades of research showing no evidence of kidney or liver harm in healthy people taking standard doses. The most commonly reported side effect is mild water retention in the first few weeks of use.
If you have an existing kidney condition, are pregnant or breastfeeding, or are on medication that affects kidney function, talk to a doctor before starting creatine. Choosing an NSF Certified for Sport or Informed-Sport product also reduces the risk of a contaminated or mislabeled product. That matters most for anyone subject to drug testing. For general dietary supplement safety guidance, see the NIH Office of Dietary Supplements fact sheet on supplements for exercise and athletic performance.
Frequently Asked Questions
Is creatine monohydrate better than other forms like HCl or buffered creatine?
For most people, yes. Creatine monohydrate has far more research behind it than newer forms, and none of the alternative forms has been shown to outperform it for strength or muscle gains.
Do I need to cycle off creatine?
No. Creatine monohydrate is safe for continuous daily use at a 3-5g maintenance dose. Cycling on and off is not necessary and does not appear to add any benefit.
Which creatine on this list is best for athletes in drug-tested sports?
Momentous Creatine Monohydrate and Klean Athlete Klean Creatine are both NSF Certified for Sport, the standard most drug-tested competitive athletes look for. Thorne is also NSF Certified for Sport and offers a larger container at a similar price per serving.
What is the cheapest way to buy creatine?
BulkSupplements Creatine Monohydrate and Naked Nutrition Creatine Monohydrate offer the lowest price per serving on this list, both landing well under $0.35 per 5g dose when bought in a larger size.
