Creatine isn’t just for bodybuilders.

1. Thorne Creatine
Best Creatine for Fighters
Combat athletes have an additional consideration when buying supplements: What’s actually in the container?
That makes Thorne Creatine an easy choice for the top spot.
Each scoop delivers 5 grams of creatine monohydrate in an unflavored powder that can easily be mixed into water, a protein shake or another beverage.
More importantly for competitive athletes, Thorne Creatine is NSF Certified for Sport. That certification provides another level of assurance for athletes who may be subject to drug testing.
The downside is price. There are certainly cheaper ways to buy creatine monohydrate. However, competitive athletes may find the additional certification worth paying for.
Pros
- 5 grams of creatine per serving
- NSF Certified for Sport
- Unflavored
- Simple formula
- Established sports nutrition brand
Cons
- More expensive than budget creatine powders
Best for: MMA fighters, boxers, wrestlers and other competitive athletes
Combat Press Verdict: If you’re a competitive fighter and third-party sport certification is a priority, Thorne is where we would start.
2. Optimum Nutrition Micronized Creatine Powder
Best Everyday Creatine
Optimum Nutrition has been a staple of the sports supplement industry for decades, and the company’s approach to creatine keeps things refreshingly simple.
Optimum Nutrition Micronized Creatine Powder provides creatine monohydrate in a micronized powder designed to mix easily into your beverage of choice.
There are no exotic creatine variations or complicated proprietary blends here. It’s simply a convenient way to add creatine monohydrate to your daily supplement routine.
That also makes it an excellent companion to Optimum Nutrition Gold Standard Whey. Athletes already using a post-training protein shake can add their creatine and knock out both supplements at once.
Pros
- Creatine monohydrate
- Micronized powder
- Easy to add to shakes
- Well-established brand
- Widely available
Cons
- Athletes prioritizing sport-specific certification may prefer another option
Best for: Everyday training, strength and recovery
Combat Press Verdict: Optimum Nutrition is an excellent choice for someone who wants a straightforward creatine from one of the most recognizable names in sports nutrition.
3. Nutricost Creatine Monohydrate
Best Budget Creatine
Creatine doesn’t need to cost a fortune.
That’s the biggest argument for Nutricost Creatine Monohydrate.
A 500-gram container provides approximately 100 5-gram servings, making it particularly attractive to athletes who take creatine every day.
That’s important because creatine isn’t something you need only after a particularly brutal sparring session. Consistent daily supplementation is the goal, which makes cost per serving an important consideration over the course of a year.
Nutricost keeps the formula straightforward while delivering the quantity needed for long-term use.
Pros
- Excellent cost per serving
- 5-gram serving
- Large 500-gram container available
- Unflavored
- Straightforward formula
Cons
- Fewer premium features than higher-priced competitors
Best for: Athletes looking for maximum value
Combat Press Verdict: If you’re primarily interested in getting plenty of creatine monohydrate without paying premium prices, Nutricost deserves serious consideration.
4. Naked Nutrition Creatine Monohydrate
Best Minimalist Creatine
Some supplement labels look like chemistry experiments.
Naked Nutrition takes the opposite approach.
Naked Creatine is aimed at athletes who want a straightforward supplement without unnecessary extras. That makes it particularly appealing to consumers who already prioritize simple ingredient lists with their protein powders, pre-workouts and other supplements.
The unflavored format also makes it easy to incorporate into an existing nutrition routine.
Throw it into your post-workout whey protein shake and you’re done.
Pros
- Simple formulation
- Creatine monohydrate
- Unflavored
- Easy to combine with protein shakes
- Good fit for minimalist supplement stacks
Cons
- Athletes who prefer flavored products may find it boring
Best for: Athletes who prioritize simple supplement formulas
Combat Press Verdict: Naked Creatine is one of the easiest recommendations for anyone who wants to know exactly what they’re adding to their supplement stack.
5. Sports Research Creatine Monohydrate
Best Premium Creatine
Rounding out our top five is Sports Research.
The company offers creatine monohydrate products, including a version using Creapure creatine monohydrate. Creapure is a recognizable name among serious supplement buyers and provides another option for consumers willing to spend a little more on their creatine.
Sports Research also has creatine products listed through NSF’s Certified for Sport program, making the brand particularly interesting for competitive athletes.
Pros
- Creatine monohydrate
- Creapure option
- Sport-certified options
- Premium positioning
- Reputable supplement manufacturer
Cons
- Premium options can cost more per serving
Best for: Athletes looking for a premium creatine monohydrate
Combat Press Verdict: Sports Research is an attractive alternative to Thorne for athletes looking for premium creatine, particularly shoppers specifically seeking Creapure.

What Is Creatine?
Creatine is a naturally occurring compound stored primarily in skeletal muscle. During short, intense bouts of exercise, the body’s phosphocreatine system helps regenerate adenosine triphosphate, better known as ATP.
That matters for combat sports.
Explosive takedowns, scrambling, heavy combinations, clinch exchanges and strength training all require repeated bursts of high-intensity effort. Creatine supplementation can increase muscular creatine stores and has been extensively studied for its ability to support high-intensity exercise performance and training adaptations.
Is Creatine Good for MMA Fighters and Combat Athletes?
Creatine can be particularly relevant to combat athletes because MMA, wrestling, boxing, kickboxing and BJJ combine strength, power, repeated high-intensity efforts and demanding training schedules.
However, fighters have an additional concern that the average gym-goer doesn’t: weight.
Creatine can increase body mass, particularly through increased water stored within muscle. For someone trying to make a strict weight limit, that needs to be factored into the overall nutrition and weight-management strategy.
That doesn’t necessarily mean fighters should avoid creatine. It means competitors should consider how supplementation fits into their individual training camp and weight-cutting plan rather than making major changes immediately before stepping on the scale.
How Much Creatine Should You Take?
For most adults using creatine monohydrate, 3 to 5 grams per day is a commonly used maintenance dose.
Some protocols begin with a loading phase involving higher daily intake divided into multiple servings before transitioning to a maintenance dose. However, loading isn’t required to eventually increase muscle creatine stores. Taking a standard daily dose consistently can accomplish the same goal more gradually.
Always follow the manufacturer’s directions and consider discussing supplementation with a qualified health care or sports nutrition professional, particularly if you have an underlying medical condition or take medications.
Creatine Monohydrate vs. Creatine HCl: Which Is Better?
Walk through the virtual supplement aisle and you’ll encounter creatine hydrochloride, buffered creatine, creatine nitrate and plenty of proprietary variations.
Don’t let marketing make this more complicated than necessary.
Creatine monohydrate has an enormous amount of research behind it and remains the logical starting point for most athletes. More expensive doesn’t automatically mean more effective.
That’s why all five products on this list center around creatine monohydrate.
Powder vs. Creatine Gummies
Creatine gummies have exploded in popularity because they’re convenient and taste better than unflavored powder.
But convenience comes at a price.
Powder typically makes it easier and cheaper to consume a full daily serving of creatine. Gummies can also introduce additional ingredients and calories that aren’t necessary if your only goal is creatine supplementation.
For fighters closely tracking calories and macronutrients during camp, plain creatine powder is particularly easy to manage.
Do You Need to Cycle Creatine?
Creatine isn’t a stimulant, so it doesn’t need to be treated like caffeine or a high-stimulant pre-workout.
Many athletes take creatine consistently rather than cycling on and off. The more important factor is consistency.
If you’re unsure whether long-term creatine supplementation is appropriate for your circumstances, discuss it with your physician or sports dietitian.
