Martial Arts and Supplements: What Works? What Doesn't?

Walk into almost any gym or pro shop and you'll find a shelf full of powders, capsules, pre-workouts, amino acids, recovery blends, fat burners, greens, mushroom extracts, testosterone boosters, and whatever else the supplements industry decided was going to change your life this month.

Martial artists are not immune to the hype.

We want more speed, more power, better endurance, faster recovery, sharper reactions, and enough gas in the tank to throw the same kick in the fifth round that we threw in the first.

The problem is that supplement marketing tends to put everything on the same playing field. A coumpound supported by decades of research can sit right beside a product backed mostly by a cool label and three viral TikToks

So, what actually works?

First, an important point: supplements are exactly that. Supplements.

Nothing in a tub, capsule, or packet replaces consistent training, adequate sleep, sufficient calories, good nutrition, and hydration. But once those foundations are in place, there are a handful of ingredients that can actually genuinely help.

 

Creatine: It Works

Creatine Monohydrate is probably the easiest place to start. 

It is one of the most extensively studied sports supplements available, and its benefits are particularly relevant to martial arts. Creatine helps increase the availability of rapid energy during short, explosive efforts. Think combinations, takedown attempts, explosive kicks, flurries, scrambling, pad rounds, and repeated bursts during sparring.

For most athletes, roughly 3-5 grams per day is a commonly used maintenance range. Loading protocols can saturate muscle stores faster, but they are not necessary if you're willing to take it consistently over time.

There is one consideration for combat athletes: creatine supplementation can increase body mass, largely through additional water stored in the muscles. If you compete in a weight-class sport, that should be factored into your plan rather than discovered two days before weigh-ins

Verdict: Strong evidence.

Not flashy. Not new. Just effective.

Caffeine: Effective, but More Is Not Better

There is a reason caffeine appears in so many performance products.

It works.

Caffeine can improve alertness, reduce the perception of effort, and support performance across endurance activity, repeated sprint efforts, and short-duration high-intensity exercise. Research involving combat athletes has also found benefits to strength, power, muscular endurance, and high-intensity performance.

But this is also an ingredient where people regularly confuse "effective" with "take as much as possible."

That is a mistake.

Large doses do not necessarily produce better results and can bring nausea, jitters, elevated heart rate, anxiety, and insomnia. If your pre-workout makes you feel like you can hear colors but destroys your timing and keeps you awake until 3 a.m., you have probably missed the point.

Different athletes also respond very differently to caffeine.

Verdict: Works well when used intelligently.

Know your tolerance, and test it during training before using it in competition.

Carbohydrates: Not Sexy, Extremely Important

Carbohydrates rarely get treated like a performance supplement because they are food.

Your muscles do not care about marketing categories.

Combat sports combine explosive anaerobic efforts with a substantial aerobic demand. As matches get longer, aerobic metabolism plays an increasingly important role, even while fighters continue producing short, high-output bursts.

That requires fuel.

Sports drinks, gels, chews, honey, dextrose, maltodextrin, and other rapidly digestible carbohydrate sources can be useful when training is long, intense, or repeated throughout the day. The Australian Institute of Sport classifies sports gels, sports drinks, sports confectionery, and similar carbohydrate products among its Group A sports foods, meaning they have strong evidence for use in appropriate sporting situations.

You probably do not need a gel to survive twenty minutes of light forms practice.

A two-hour fight session or an all-day tournament is another story.

Verdict: Absolutely useful when the workload calls for it.

Sometimes the best performance supplement is simply fuel.

Electrolytes: Useful, but Context Matters

Electrolytes occupy a strange place in sports nutrition because they are simultaneously important and overhyped.

If you are sweating heavily through a long session, training in heat, doing multiple workouts, or competing through an extended tournament day, replacing fluid and sodium can matter.

If you have been sitting at a desk for six hours and drinking plenty of water, adding neon-colored electrolyte powder is unlikely to unlock your hidden potential.

Electrolyte products are included in the Australian Institute of Sport's Group A sports-food category, but the key phrase is "specific situations."

Verdict: Useful when you actually need replacement.

Hydration is a strategy, not a flavor packet.

Beta-Alanine: It Works, but You Have to Actually Use It Correctly

Beta-alanine is another supplement with legitimate evidence behind it.

It increases muscle carnosine, which helps buffer some of the acidity associated with hard, sustained high-intensity exercise. That makes it potentially useful for repeated, difficult efforts where that familiar burning sensation begins to limit output.

Combat-sport research has shown potential benefits in high-intensity intermittent performance, and major sports-nutrition frameworks classify beta-alanine among evidence-supported performance supplements.

The catch is that beta-alanine is not primarily an "I took this fifteen minutes ago, now I'm superhuman" supplement.

Its benefits come from consistent supplementation that raises muscle carnosine over time.

It can also cause temporary tingling of the skin, known as paresthesia. That sensation may make your pre-workout feel powerful, but the tingling itself is not evidence that you are performing better.

Verdict: Legitimate, particularly for sustained high-intensity work.

Just understand what it actually does.

Sodium Bicarbonate: Yes, Seriously

Baking soda has more performance research behind it than a depressing number of expensive supplements.

Sodium bicarbonate acts as a buffering agent and can improve performance in certain high-intensity exercise situations. It appears alongside caffeine, creatine, nitrate, and beta-alanine in evidence-based sports supplement frameworks.

There is, however, a pretty significant catch.

It can absolutely wreck your stomach.

An ergogenic aid becomes considerably less ergogenic when you are sprinting toward a bathroom.

For athletes interested in using bicarbonate, this is something to experiment with carefully during training, never for the first time on tournament morning.

Verdict: Works, but probably not where beginners should start.

Protein Powder: Useful, but It Isn't Magic Powder

Protein supplementation works because protein works.

Martial artists need adequate protein to repair tissue, adapt to training, and maintain lean mass, particularly during periods of calorie restriction or weight management.

The 2025 International Society of Sports Nutrition position stand on combat sports recommends protein intakes ranging roughly from 1.2 to 2.4 grams per kilogram of body mass depending on the athlete and training situation.

If you can hit your protein requirements through normal food, great.

If your schedule means you finish class at 9 p.m. and a shake is considerably easier than preparing chicken and rice, protein powder is an extremely convenient tool.

The powder itself is not inherently superior to food.

Verdict: Effective and convenient, but not magical.

BCAAs: Probably Not Doing What You Think

This one might make a few supplement companies angry.

Branched-chain amino acids have been marketed heavily for muscle growth and recovery, but their usefulness becomes questionable when an athlete already eats adequate high-quality protein.

The Australian Institute of Sport moved BCAAs into Group C, a category for supplements where scientific evidence does not support a meaningful benefit for athletes or remains insufficient to recommend their use.

Complete protein already contains BCAAs along with the other essential amino acids your body needs.

Verdict: Usually unnecessary if your protein intake is already solid.

Your money can probably be spent somewhere else.

Vitamins and Minerals: Fixing a Deficiency Works. Megadosing Usually Doesn't.

Iron, vitamin D, calcium, magnesium, zinc, and other micronutrients are essential.

That does not mean taking huge amounts makes you perform better.

Correcting an actual deficiency can absolutely improve health and performance. Taking more of a nutrient when you already have enough generally does not transform it into an ergogenic aid.

In fact, the AIS currently places standalone magnesium supplementation in Group C for athletic performance.

This is an important distinction.

"Your body needs this" and "taking extra improves athletic performance" are not the same statement.

Verdict: Address genuine nutritional needs. Do not chase megadoses.

Adaptogens, Herbs, and the Gray Area

This is where things get more interesting.

Ingredients such as ashwagandha, maca, schisandra, various mushroom extracts, and other botanicals are increasingly appearing in performance products.

Some have promising research around stress, fatigue, cognition, recovery, or exercise performance. That does not automatically put them in the same evidence category as creatine or caffeine.

Research can vary depending on the specific extract, dose, population studied, duration of use, and outcome being measured.

That does not mean every herbal ingredient is useless.

It means we should be comfortable saying, "This looks promising, but we don't know as much about it yet."

Good sports nutrition does not require pretending every ingredient is equally proven.

Verdict: Interesting, potentially useful, but ingredient and dose matter.

Treat emerging evidence as emerging evidence.

What About Pre-Workout?

"Pre-workout" is not an ingredient.

It is a product category.

One pre-workout might contain useful doses of caffeine, beta-alanine, nitrates, and carbohydrates. Another might contain microscopic amounts of twelve ingredients hidden behind a proprietary blend.

Judge the ingredients and doses, not the lightning bolts on the container.

The same rule applies to recovery powders, hydration products, energy gels, and almost everything else in sports nutrition.

One More Thing: Competitive Athletes Need to Think About Contamination

For martial artists competing under anti-doping rules, supplement quality matters just as much as supplement efficacy.

USADA warns that dietary supplements are regulated differently from medications and that labels cannot guarantee a product is free from prohibited or undeclared substances. USADA recommends athletes who choose to use supplements reduce their risk by selecting products certified through NSF Certified for Sport, while emphasizing that even certification cannot reduce risk to zero.

If you compete at a level where drug testing is possible, "I bought it at a nutrition store" is not enough due diligence.

The Bottom Line

The supplement industry loves complexity.

Performance usually does not require it.

Get enough sleep.

Eat enough protein.

Eat enough carbohydrates to support your workload.

Stay hydrated.

Train consistently.

Then, if you want to squeeze a little more out of your preparation, look toward ingredients with actual evidence behind them.

Creatine works.

Caffeine works.

Carbohydrates work.

Protein works.

Electrolytes work when you need them.

Beta-alanine, bicarbonate, and nitrate can have legitimate applications.

A lot of the rest ranges from "maybe" to "probably unnecessary" to "someone put this in a black bottle and hired a shredded guy to sell it."

Martial arts teaches us to eliminate wasted movement.

Your nutrition should follow the same philosophy.

Fuel your training. Sharpen your mind.
