CrossFit, at its roots is a lifestyle.

But, most people know CrossFit® as a type of workout that is based on functional fitness (things you do in everyday life) and being “ready for anything”.

Workouts are varied in both movement and intensity. With a CrossFit workout, there is never a dull moment!

Although CrossFit is touted as “constantly varied”, there are major factors of fitness that influence an individual’s ability to complete a CrossFit workout, as well as the fitness modality that is directly impacted as a result of frequent CrossFit training and workouts.

I.e. there are factors of fitness that are tested and there are direct improvements in those factors as a result of repeated CrossFit-type workouts.

Generally, CrossFit workouts consist of a variety of these factors.

These factors are defined as the Ten General Physical Skills: endurance, stamina, strength, speed, power, flexibility, accuracy, coordination, balance, and agility.

More Than Just A Workout

At this point in CrossFit’s history, most people know that CrossFit is more than just a workout, but is truly a “lifestyle” of finding each individual’s most optimal health.

With any lifestyle, there are many pieces of the larger puzzle that go into finding one’s own “optimal”.

That includes: nutrition, recovery, sleep, stretching, hydration, stress management, time management.

An often overlooked aspect of the nutrition component are supplements for CrossFit.

The reason they are often overlooked, or rather ignored, is because the industry is full of scams and snake oil that really has no benefit whatsoever.

HOWEVER, let’s not throw the baby out with the bathwater … what are the best supplements for CrossFit?

What are the best supplements for CrossFit?

The Best Supplements For CrossFit & CrossFit Athletes

Per say, there aren’t any supplements endorsed as “CrossFit supplements”, but using the Ten General Physical Skills that I mentioned before, you can piece together supplements that are not only effective, but will significantly increase your results on your fitness journey.

The following is a supplement guide that illustrates the best supplements for CrossFit athletes and improving all aspects of “fitness”.

1. Cardiovascular/Respiratory Endurance

The ability of body systems to gather, process, and deliver oxygen.

So, simply put, how long can you go and sustain a high level of performance during a workout?

APEX O2 is one of the best supplements for CrossFit athletes

Including an endurance supplement with ingredients like Beetroot powder and Beta-Alanine can boost your endurance by nearly 20% by increasing O2 and reducing lactic acid build up, which is often the culprit of the muscle soreness we feel after a great workout.

A product with BEETROOT like APEX O2™ is one of the perfect supplements for Crossfit to boost your endurance and reduce post-workout muscle soreness and fatigue!

P.S. It is a great supplement for runners, too!

2. Stamina

The ability of body systems to process, deliver, store, and utilize energy. If you want to go longer and stronger during your workouts, you need to find a way to increase your stamina.

Supplements for Crossfit like Beta-Alanine, Caffeine, Vitamin B-12 can give your body the energy it needs to get the best from each and every workout.

Formula-H is the best pre-workout supplement for CrossFit athletes

✅ Let’s Settle A Bet: The Best CrossFit Pre-Workout?

To improve your energy levels try the best pre-workout for CrossFit, FORMULA-H®, which includes essential Beta-Alanine and Caffeine.

Add in FORMULA B-12™ to boost your metabolism and energy levels!

3. Strength

The ability of a muscular unit, or combination of muscular units, to apply force.

Who doesn’t want to be stronger? After all, stronger people are more resilient and adaptable in life! Regardless of what sport you play; powerlifting, HIIT classes, running or another type, strength is important for success.

The good news is that strength can be honed with training AND supplements.

The best supplements for Crossfit and boosting strength include Creatine, Zinc, Magnesium and Whey Protein.

Supplements for Crossfit

Creatine works works by increasing the availability of creatine and phosphocreatine (PCr) within the muscle, helping to maintain energy during high-intensity exercise such as weightlifting. Additionally, increasing the availability of PCr may help speed up recovery between sets.

A Pure, Micronized Creatine is best, and you can find that with PURE CREATINE™.

• • •

Zinc and Magnesium have been shown to naturally increase free testosterone, which directly leads to improvements in overall strength. These are some of the best workout supplements for men.

Adding a high-quality Whey protein to your diet will promote protein synthesis and an anabolic environment, leading to remarkable gains in your muscle mass AND strength.

ZEN R.E.M. is one of the best supplements for CrossFit athletes because it helps boost recovery and optimize sleep.

Grab specific strength formulated supplements like PURE CREATINE™, ZEN R.E.M.™ to help you increase your endurance and testosterone.

The best CrossFit protein powder will have close to 2.5g of BCAA L-Leucine per serving … I highly recommend YES! Whey™ All-Natural Protein to hit your strength goals like a savage! (Plus it’s grass-fed, too!)

4. Flexibility

The ability to maximize the range of motion at a given joint.

Super Flexy

In order to improve your flexibility and range of motion, you need to decrease the inflammation surrounding your joints and tissues AND lubricate your joints to reduce friction and wear and tear.

Supplements like Turmeric reduce inflammation naturally in the bones, joints and tissues, while adding Glucosamine, Chondroitin and MSM helps draw water into the joint and tissues, lubricating them so you feel good when you’re moving around … and are the best supplements for joint pain.

Of all the joint health supplements for Crossfit on the market, Try an all-in-one solution to alleviate your joint pain and inflammation with SUPER FLEXY® – it is the best joint health supplement available!

5. Power

Power is the ability of a muscular unit, or combination of muscular units, to apply maximum force in minimum time.

If your goal is to get as big and as strong as possible, then it would make a lot of sense for you to start including supplements like Creatine, Branched Chain Amino Acids (BCAAs) and Citrulline Malate into your nutrition.

Creatine works works by increasing the availability of creatine and phosphocreatine (PCr) within the muscle, helping to maintain energy during high-intensity exercise such as weightlifting.

Furthermore, increasing the availability of phosphocreatine may help speed up recovery between sets. A Pure, Micronized Creatine is best, and you can find that with PURE CREATINE™.

BCAAs are Leucine, Iso-Leucine and Valine and help to regulate protein metabolism by promoting protein synthesis and suppressing protein degradation, which improves recovery of muscles damaged during resistance training.

Looking for the perfect supplements for CrossFit recovery, that also tastes great?

Look no further than GO JUICE®!

BCAAs are some of the best supplements for Crossfit so you can do more work, faster!

Citrulline supplements, Like FORMULA-H® Pre-Workout, help boost ATP production, boosting the amount of power and energy someone can harness during a lifting session.

Additionally, adding in 20-30 grams of high-quality Whey protein like YES! Whey All-Natural Protein, will promote protein synthesis, leading to improvements in power output and recovery from workout to workout!

6. Speed

The ability to minimize the time cycle of a repeated movement. In any sport, it’s not the minutes that count, but the seconds – sometimes even the milliseconds. This is the same in most sports, from rowing to running. Straight up, speed plays a critical role in improving your overall success in any sport!

The great thing about improving your speed, is, there are quite a few supplements that can help you during your training.

Those include Caffeine, Beetroot powder and Probiotics (Yes! Gut health is essential for speed development!).

Caffeine, like the 250mg found in FORMULA-H®, is probably the most widely used ergogenic aid for athletes, but it really does boost the body’s ability to improve cycle time from running, lifting or any other sport.

Beetroot powder, found in APEX O2™, provides essential oxygen and ATP support to fuel the body’s energy system and improve your speed both now AND later.

Lastly, and maybe the biggest eyebrow raiser here, would be adding a Sport Probiotic to your nutrition.

Hear me out on this … athletes have realized that using probiotics are catalysts for essential vitamins and their absorption like Vitamin-D, Iron, Zinc and Magnesium.

Many athletes have poor gut health, and when absorption is impaired, it compromises the entire system.

In fact, Zinc deficiencies can result in a down regulation of the thyroid to the point where energy/caloric expenditure is reduced.

Hands down, a good probiotic is one of the essential supplements for Crossfit – and helps other supplements work better, too!


Don’t think that yogurt and other trendy fermented food products like Kombucha are enough to make a difference; they are more complementary because they usually have limits to the variety of strains.

Pick up a specifically designed Sport Probiotic like ADAPTOGENIC SYMBIOTIC™ and SUPER GREENS™ to get full spectrum of essential probiotics to improve your gut health, and overall speed.

7. Coordination

The ability to combine several distinct movement patterns into a singular distinct movement.

Coordination may not be the sexy thing all the gym rats are talking about, but improving your coordination can improve your athletic performance, your daily life AND reduce your injuries. 

To improve your coordination, a program that includes core strength exercises as well as supplements Ginseng, Guarana and Turmeric will improve your overall athletic output and prevent injuries.

Don’t get derailed from your training and improve your Coordination quickly by picking up specifically formulated supplements for Crossfit like ATARAXIS™ and SUPER FLEXY®.

8. Agility

The ability to minimize transition time from one movement pattern to another.

For athletes that require quick movements from side to side, front to back and all around, improving your agility can be the difference between first and being forgotten.

You don’t want to be forgotten and end up last, so including supplements like Turmeric, Glucosamine and Chondroitin improve your ability to move through space quickly and efficiently, improving your performance in everything you do!

My recommendation? Pick up a bottle of SUPER FLEXY® (one of the best supplements for CrossFit!!) and improve your agility quickly!

9. Balance

The ability to control the placement of your body’s center of gravity in relation to its support base.

Balance helps us in everything we do, from competitive sport, to walking and staying steady just standing around.

As a notable benefit, having optimal control over your balance, will also help reduce the risk of injury too (and being injured sucks!).

In addition to a great core strength routine, supplements can also improve your balance by improving your ability to move through space and reduce and pain or friction you might have in your body.

Supplements for CrossFit like SUPER FLEXY® that contain Turmeric and Collagen Type II will improve your balance significantly and reduce the likelihood you’ll get injured. Stay on your “A” game kids!

10. Accuracy

The ability to control movement in a given direction or at a given intensity.

Why is accuracy important for you?

In sports, there is always a winner, often times it’s the team or individual that was most often on point. And this is why accuracy is important. Whether you partake in football, basketball, powerlifting, bodybuilding or any other sport, being accurate helps you get over the finish line, and with precision.

Better precision and accuracy comes with a fine-tuned focus that you can improve with supplements like Ginkgo Biloba, Ginseng and Guarana.

Nootropics, or “brain-vitamins” like ATARAXIS™ can boost your accuracy and focus significantly, giving you the edge you need to be your best and finish on top!

Nootropics are also some of the best supplements for CrossFit, as they can help with fine motor skill improvement.

Very few supplements for CrossFit can influence the nervous system in a way that facilitates athletic performance like nootropics can!

So What Are The Best Supplements For CrossFit?

Supplements for CrossFit are NOT the be-all, end-all to your best fitness ever. You’ve still go to to WORK.

However, they are pieces of the puzzle that WILL help you get better results.

I’m also willing to bet that a “Rich Froning diet” or “Mat Fraser diet” also consists of adequate and appropriate supplementation!

There is no “best diet” – there is only a “best diet for the individual”.

In summary, the best supplements for CrossFit are those that improve the ten general physical skills: Endurance, stamina, strength, speed, power, flexibility, accuracy, coordination, balance, and agility.
