What are the Best Keto Pre Workouts?
Get the Extra Boost You Need

I have written about my foolish mistake during my first keto attempt when my pre and post-workout supplements kicked me out of ketosis. Basically, I didn’t pay attention to the nutritional info, and I ended up with a load of unwanted carbs.

My initial reaction was to stop taking a pre-workout formula altogether, which in turn had an effect on my performance at the gym. It was a very frustrating time that you can avoid altogether.

See, when you’re on a keto diet, then keto pre workouts are actually very important as you won’t have the readily available glucose to tap into.

Over the past couple of years, I’ve done a lot of research and tested dozens of different "keto pre workouts." Out of all the tests, only 4 really stand out as truly keto-friendly.

Before we get to that list, let me address one of the most common questions I get.

Is Pre Workout Keto Friendly?

Yes, pre-workout supplements are keto friendly, as long as you pay close attention to nutritional values.

The problem is that many pre-workout supplements are packed with easily digestible glucose to give you a fast energy boost ​to enhance weight loss. It’s these types of products that you have to stay clear of as they can mess up your ketosis.

Here is a list of recommended keto pre workouts that can improve your overall training program:

1. Perfect Keto Perform

It really doesn’t get better than Perfect Keto Perform Pre-Workout Powder when it comes to boosted energy and low carbs. I’ve had a running subscription for at least 2 years now, and it has never failed me.

While it isn’t the cheapest option, the subscription plan does give you an extra 15% discount.

With 7.7g BHB, 5g MCT, BCAA, creatine, L-citrulline, beta alanine, and green tea caffeine, you can hit two birds with one stone — crush your sets and boost your ketone levels.

Most importantly, there are less than 1g of carbs, so you don’t even have to make special adjustments to your diet on the days that you hit the gym.

Another bonus is that you will stock up on important minerals and electrolytes including magnesium, calcium, and sodium.

These are especially important on a keto diet when you might be struggling to balance fat and carbs with vitamins and minerals.

The lemon flavor of this formula tastes great without being overwhelming. It’s easy to drink an entire glass of it before exercise without plugging your nose to avoid the taste.


  • Helps you perform your best to accomplish weight loss goals
  • No additives or fillers
  • Keto-friendly with less than 1g of carbs
  • Great flavor that makes it quite refreshing


  • None


To use Perfect Keto Perform, you just need to mix 1 scoop of the powder with 8-10 ounces of water.

Do this 15-30 minutes before your workout and experience the best possible results from your gym session.

Our Thoughts

We highly recommend the Perfect Keto Perform Pre-Workout. It offers the very best weight loss results and is guaranteed to be keto diet-friendly.

Additonally, its lemon flavor tastes great.

2. BPI Sports Pre Workout

BPI Sports is one of the leading sports nutrition companies in the world. The company is trusted by top performing athletes to get the best out every training session.

Scientifically designed to boost your strength and stamina, this pre-workout supplement has all the ingredients your body will crave with none of the fillers, carbs, and sugars that are so common.

The caffeine included in this formula helps you to power through your training, which is especially useful while on a low-carb diet. Just make sure that you drink more water than usual, as caffeine has a dehydrating effect on the body.

With performance-boosting ingredients like CDP-Choline, this formula helps you get a sharp mental focus during your training and gym sessions.

This helps you stay dedicated and motivated throughout the entire session.

Designed for low-carb diets like the ketogenic diet, this pre-workout supplement provides your body with MCTs and BHB salts which can help your body turn to fat stores for energy.


  • Increases endurance and energy
  • Promotes mental clarity
  • Designed for low-carb diets with 0 carbs
  • Helps to tap into fat storage for energy


  • Taste can be improved


To get the benefits of this product, you only need to take one scoop blended into 8 ounces of water about 15-30 minutes before training.

With flavors like blue lemon ice, watermelon ice, apple pear, and tropical freeze, it’s easy and refreshing to gulp down.

Our Thoughts

This is a good and effective ketogenic pre-workout supplement that gets the job done. It will help keep you motivated through your gym session

Designed specifically to keep your carb intake down to a minimum, it won’t mess with your ketosis.

If you think it’s the keto pre-workout you’ve been looking for, then we recommend buying it directly from the manufacturer by clicking the image or button above. 

3. Sheer Strength Pre Workout

The name of this ketogenic pre-workout supplement says everything you need to know. Sheer Strength is designed for the high-performance athlete that expects peak performance in every single training session.

But it’s not just a performance supplement as the chosen ingredients account for exactly what a keto dieter needs: plenty of electrolytes, minerals, L-Citrulline, and no carbs.

It’s the L-Citrulline that helps boost your performance as it promotes blood flow and energy delivery to muscles. You will definitely notice this the first time you take it.

The added BHB-salts are vital to replenish lost electrolytes, both as a result of your training and ketosis. Staying hydrated is one of the most important things to ensure your mind and body work at their best.

Like the other two pre-workout formulas we’ve reviewed, this one has everything you need to stay motivated and focused throughout your training.


  • Provides necessary antioxidants and electrolytes
  • Supports endurance, focus, and drive
  • Contains BHB salts


  • The taste isn’t great with a lingering aftertaste
  • Does not provide the same boost as the first on this list


Dissolve one scoop in 8-10 ounces of water and enjoy. The crushing punch flavor packs a blow into your gym session and some flavor into the mixture.

Our Thoughts

Sheer Strength Pre Workout Powder is an effective keto pre-workout that will work great if you’re on a low-carb diet.

It’s also available as a caffeine-free version, but when it comes to tough training sessions that little extra ingredient can help you stay focused.

4. Cellucor C4 Pre-Workout

The final recommendation I have is Cellucor C4 Ultimate. Now, I have to say from the start that this really is targeted at high-performance athletes to help boost energy, endurance and mental performance when you need it most.

You won’t need this every day, and maybe not even every week, but for those workouts where you are truly pushing yourself to the limits, it will give you that extra physical and mental strength you need.

Each scoop contains 6g citrulline malate and 1.5g creatine nitrate which will really help with your pumps.

You’ll be surprised how easy it is to increase your reps or add some extra weight, all leading to a much faster bulking process.

With 0g of sugar or other carbs, it will make it a lot easier for you to adjust your daily meal plan. It’s always a bonus when your exercise plan allows for a few extra carbs, so why waste them on your supplements?

Finally, you’ll love the flavors and easy mix. Available in Cherry Limeade, Icy Blue Razz, Orange Mango, Sour Batch, and Strawberry Watermelon, it gives you plenty of tasty options without having to use a blender for the perfect mix.


  • Superb formulation of patented ingredients
  • Provides excellent energy, endurance, and pumps for your entire training session
  • Available in great flavors
  • Boosts mental energy to give you huge motivation


  • Quite expensive compared to the other options
  • Requires 45 to 60 minutes to get the full boost, so time it well.


Mix 1 scoop with 10 oz of water and shake well.

Take it 45-60 minutes before your workout session, ideally timed to when you hit the high-intensity part of training after your warm-up routine.

Our Thoughts

For maximum performance and stamina, you really cannot beat Cellucor C4 Ultimate. The combination of ingredients works exceptionally well to really help pump through the toughest part of your training.

It’s not the cheapest option here, but for those maximum intensity days, it will give you the edge to succeed.

​Should I Eat Carbs Before or After a Workout?

food group of carbohydrates

While the keto pre workout supplements we looked at above will no doubt help you achieve your exercise and weight loss goals, many folks still wonder whether they should eat their allotment of carbs before or after they workout.

It’s a valid concern, because the last thing you want is to have excess carbs clanging around in your system kicking you out of ketosis.

Here are a couple of lines of thought on the subject.

  • Carbs Before Exercise - If you typically engage in heavy duty cardio, weight training or CrossFit you may want to consume your carbs 30 minutes before working out. One reason for this is that your muscles have an elevated need for glucose when they’re being stressed and carbs are the best way to deliver it. Be aware, however, that the key word here is “heavy.” If you work out at a level of about 4 or 5 on an intensity scale of 10 then you likely don’t need to load up on carbs before your workout, as your body won’t burn them all off.
  • Carbs After a Workout - The most compelling reason to consume carbs after a workout is to optimize muscle repair and growth. You should also couple those carbs with plenty of protein. The combination of the two provides your best bet for achieving a lean, chiseled physique, if indeed that is what you are after. If you are working out at a high level and you are not providing your muscles the carbs and protein they need, you’ll find any progress quickly stalls.

​So, Which Pre Workout is the Best?

As you can see, you have several good options when it comes to selecting the best ketogenic preworkout formula for your low-carb diet. And, you should have all the information you need to make an informed decision on this.

While all of the products we covered offer great results, the Perfect Keto is hands-down the the best pre-workout and the most logical choice because it is designed specifically for people who are on the ketogenic diet or just plain avoiding carbs.

Heck, the company's survival solely relies on providing people ketogenic products so it would be safe to assume that they know what they are talking about.

Plus, we've actually tried them, and it is every last bit of what they described it to be.

It also provides energy, a tasty flavor profile, and controlled ingredients that enhance your food. Based on our experience and the facts, we are happy to say this our favorite and the one we feel most confident will get you the results you’re after.
