Best Supplements for Crossfit Athletes

CrossFit is arguably the most famous workout routine nowadays, and this is in part due to the beneficial effects you receive from this full body workout. Today we are going to look at the best supplements for CrossFit athletes so you can perform at your best in every intense workout.

Not only does it incorporate everything you need but more than anything, it keeps you engaged throughout the whole workout session.

Many people report they have tried all sorts of gym routines but nothing has kept them at the gym as consistently as Crossfit. Whether the goal is weight loss, to build muscle or be part of a fitness community, Crossfit has it all.

One of the challenges for traditional cardio workout routines is the boredom that can set in within a short space of time. Not with Crossfit. The Crossfit workouts for men and Crossfit workouts for women are amazing. Plus you get to train with a buddy. What more could you ask for?

CrossFit’s primary goal is improving:

  • power
  • flexibility
  • strength
  • muscular resistance
  • cardio-respiratory resistance
  • precision
  • balance
  • agility
  • coordination
  • speed

And let’s be honest, who doesn’t want a little more of all of those?

But it isn’t just about the exercises. You also need to consider the best diet for Crossfit as well.

Diet and nutrition play such an important role with every athlete. Which is why we are going to run through the best supplements for Crossfit athletes here.

Experience of CrossFit with a friend

A good friend of mine, Pat, has tried many types of workouts over the years.

I hadn’t caught up with him for a few months but when I did, I noticed how fit he was looking.

His story is likely a familiar one with those who do CrossFit. He’s tried all sorts of other training methods and studied all kinds of fitness programs.

When I say study, I mean study. He is one of the most knowledgeable people I know across a huge range of topics.

Suffice to say that anything Pat is looking into, is going to be researched to the hilt.

Crossfit definitely resonated from all his research.

But it was the engagement and focus it provided that really won him over.

Having tried many workouts, CrossFit was the one that has remained solid after 2 years.

Pat says his supplements for Crossfit training are pretty straightforward. He takes a whey protein isolate daily and complements it with a balanced diet. He also has postworkout supplements depending on how intense the workout is and always has a protein bar in his gym bag.

For pat, it isn’t just about muscle building and losing fat but all of that plus the focus and ease of being able to stay committed. Consistency reigns supreme when it comes to long-term workout performance and the health benefits.

The CrossFit Philosophy and the excellent benefits

CrossFit philosophy is to not only gain muscle mass but to be in shape and prepared for any type of physical requirement that the real world might throw our way. Let us dig a little deeper and learn more about CrossFit.

CrossFit is a high-intensity training routine, and as such it may help you lower your body fat percentages, increase muscle mass gains and burns a lot of calories.

So it goes without saying, that to consider the Crossfit supplements for athletes, you need to consider your Crossfit nutrition plan as well.

Studies have shown that CrossFit has the following benefits.

  • CrossFit improves aerobic capacity by about 9% in both men and women; this demonstrates that CrossFit is a training regimen used to increase resistance and optimise performance.
  • After ten straight weeks of CrossFit training total body weight is diminished anywhere between 2 and 4 percent which directly translates to a healthier Body Mass Index. CrossFit is hugely beneficial for overweight and obese people.
  • CrossFit lowers body fat percentages considerably. After ten weeks of training, the average male can see reductions in the body up to 18% while women can reasonably expect to lose around 12%.
  • Lean muscle mass is increased between 1.4 percent and 2.2 percent.

crossfit training protein and pre workout routines

CrossFit workouts or WOD’s as they are commonly known last approximately 60 minutes and are structured in the following manner.

  • Warm Up: A warm-up routine is executed to lower the risk of injury during the program. Common warm-up exercises are jumping rope, abdominal crunches, pushups and squats to name a few.
  • Part A: At this point, the training will focus on practising techniques from varied exercises that focus on building up strength. Also, to build muscle. The goal is to lift the heaviest possible weight manageable. Conventional methods used during this phase are the back or front squat, deadlift, snatch, hang clean, bench press, etc.
  • Part B: This is the most intense section of the routine. During this phase, the overall weight being lifted is lowered significantly with the primary goal being strengthening respiratory capacity.

WOD’s can be done in several different ways, for example As Many Rounds As Possible consists of executing as many rounds as possible of a given combination of exercises within a certain amount of time.

Every Minute on the Minute consists of executing a given number of repetitions of a particular exercise within a minute of time for as many minutes as the trainee can manage.

Time left over within that minute after the repetition goal has been achieved is used for a rest period. This technique ends when the athlete is no longer able to execute the specified number of repetitions within the minute period.

The weight being lifted during these phases is highly personalised, and the goal is to always improve from previous workout sessions.

4 Best supplements for CrossFit athletes

Given how intense a CrossFit session can be, you would benefit significantly from complementing your routines with smart supplementation.

Any given activity within a CrossFit session requires maximum effort with the body approaching its limits by design; because of this, we must provide our bodies with the most efficient means of recovery afterwards.

Rest and proper diet as always play an essential role but so does nutritional supplementation.

The Crossfit supplements we recommend for athletes are:

Best protein for CrossFit

Whey Protein Powdersupplements for crossfit protein

Chemically these protein mixtures are composed of proteins such as Beta-Lactoglobulin, Alfa-Lactoglobulin, and Serum Albumin.

These are some of the highest sources of proteins known to man and like this provide a high percentage of amino acids during high-intensity training.

Whey protein will significantly enhance muscle growth and improve tissue regeneration.


Protein8 Revolution has been expertly formulated with slow, medium and fast digesting proteins and amino releasing matrix.

This is so that the protein goes where it is needed most and does so efficiently. And with Protein8 Revolution, you are getting 30 grams of protein per serve. Perfect.

If you are looking for the ultimate protein for building lean muscle fast, then Protein 8 Revolution is for you.

Every CrossFit athlete should be supplementing with some protein powders. And we believe this is one of the best protein for Crossfit gym-goers. Certainly one of the tastiest protein shakes on the market.

Creatine Supplements for Crossfit Athletes

Arguably the most popular supplements among athletes of all disciplines.

Taking creatine monohydrate is a direct and immediate source of muscular energy as it is indispensable in the formation and recycling of Adenosine Triphosphate.

ATP is the basic unit of cellular energy and is required for all metabolic processes. As you can imagine, there are many benefits of taking creatine with any Crossfit or strength training program.

Studies have shown time and again that creatine supplementation dramatically improves performance and recovery.

It is recommended for use before and after your workouts. But the recommended dose is around 3-5 grams of creatine per day.


CXS REVOLUTION contains some of the most creatine rich pharmaceutical grade sources known to man. Fenugreek extracts that will improve insulin sensitivity to ensure creatine uptake.  It also includes enough Magnesium Creatine Chelate, Creatine Gluconate, Creatinol-O-Phosphate, Tri-Creatine Malate, Creatine Ethyl Ester, and Creatine/Glycerol Phosphate; formulated to perfection so that you get creatine to your muscles efficiently and reliably.


As one of the non-essential amino acid, Beta Alanine is produced by your body in small quantities.

Beta-Alanine promotes the synthesis of intramuscular carnosine which provides excellent boosts of energy and allows you to perform better during high-intensity training.

We recommend that you supplement with Beta-Alanine daily and that you do it with MUSCLESPORT’s BLACK RHINO PRE WORKOUT SUPPLEMENT. Black Rhino is arguably the best Crossfit Pre-Workout supplement for a high octane training sessions.

It goes without saying but the intensity of a Crossfit session means a pre-workout supplement is critical for Crossfit athletes.

MUSCLESPORT’s team of expert chemists has carefully designed the perfect blend of nutrients and compounds to give you that piercing focus, energetic pumps, and perseverance.

Carefully dosed to include the ingredients increases strength and allows you to power through your high intensity activities which Crossfit is renowned for.

Fish Oil Supplements

Another excellent supplement to take is fish oil supplements.

Many Crossfit people know the importance of getting enough protein through fish. This not only provides excellent protein but omega 3s straight from nature.

Fish oil supplements are ideal because the modern diet doesn’t contain a lot of fatty fish.

Benefits of taking fish oil

The benefits of taking fish oil supplements for CrossFit are that it reduces inflammation, boosts the immune system and increases immune function.

Another powerful benefit of fish oil is you get access to the EPA and DHA anti-inflammatory agents. You can get these from your real food but the best is via supplements.

On another note, many Crossfit athletes, especially males, forget about taking Zinc and Magnesium. Zinc is great to take on its own but you may find the best way to get the other nutrients is through a multi vitamin.

Summing up the best Crossfit supplements for athletes

Not only do you want to perform your best but you need to be able to recover fast so you can hit your next Crossfit training session with intensity.

The suite of supplements above is perfect for attaining your best and helping your recovery process.

They are the ideal blend of Crossfit supplements needed to help you stay on your game and surpass your fitness goals.

But of course, with any intense exercise and athletic performance like Crossfit don’t underestimate the real food you eat too. Part of your diet plans throughout the day are getting high-quality regular food.
