Best Keto Pre-Workout Supplements

In the realm of dietary choices, I must confess to stumbling during my initial venture into the ketogenic diet. This misstep was born from a lack of meticulous attention to detail, an error I’m eager to shed light on today.

I inadvertently veered out of ketosis, that coveted metabolic state characterized by fat-burning, all due to the influence of pre and post-workout supplements. My failure lay in neglecting to closely examine their nutritional profiles, leading to an unintended surplus of carbohydrates entering my system.

Initially, my response was drastic: I ceased the use of pre-workout supplements altogether. While well-intentioned, this decision adversely affected my gym performance, causing immense frustration. Upon reflection, I realized this setback could have been easily avoided had I been more diligent in scrutinizing the nutritional content of the supplements integrated into my routine.

This realization marked the beginning of a journey of discovery. I delved into the world of pre-workout supplements tailored for a ketogenic lifestyle, recognizing the significance of selecting products that align with the specific requirements of a keto diet. The essence of the ketogenic diet lies in restricting carbohydrate intake to induce a state of ketosis, where the body utilizes fat as its primary fuel source due to a lack of readily available glucose.

In time, I engaged in extensive research and subjected numerous “keto pre-workout” supplements to rigorous testing. Today, I’m excited to share the results of my endeavors. Among the plethora of products evaluated, only four have emerged as genuinely keto-friendly.

But before unveiling my top recommendations and guiding you through the realm of keto pre-workout supplements, let’s address one of the most frequently asked questions I encounter:

Is Pre-Workout Truly Compatible with Keto?

Certainly, pre-workout supplements can align seamlessly with a keto lifestyle, provided that you meticulously scrutinize their nutritional composition.

The challenge lies in the prevalence of pre-workout supplements that incorporate easily digestible glucose to offer swift energy and purported weight loss benefits. It is of paramount importance to exercise vigilance and steer clear of such products, as they possess the potential to disrupt the delicate state of ketosis.

To assist you in making informed choices, I have compiled a selection of meticulously curated keto-friendly pre-workout supplements that have the potential to elevate and optimize every facet of your training regimen.

Top 4 Keto Pre-Workout Supplements

Onnit Shroom TECH™ Sport Review

When you step into the gym, your goal is to maximize your workout efforts. Many people turn to caffeine for that extra boost, and it does its job of giving you a jolt of energy. However, caffeine can often lead to stomach discomfort and jittery nerves.

Imagine if there was something that could provide you with that energy boost without taking a toll on your nervous system. Well, now there is – it’s called Shroom TECH Sport from Onnit. It’s not your typical stimulant; instead, it helps prevent fatigue, allowing you to push through physical barriers.

It might sound too good to be true, but Shroom TECH Sport is the real deal. But you don’t have to take our word for it. Onnit conducted a 12-week clinical study at Florida State University, and the results are impressive. Participants experienced:

  • A 12% increase in bench press reps.
  • A 7% increase in the number of bench press and back squat reps.
  • An overall 8.8% increase in cardiovascular performance.

We can attest to these results as well. Our testers reported significant improvements in their performance when they took Shroom TECH Sport before hitting the gym.


  • Shroom TECH provides a measurable boost in the gym.
  • It helps you push through performance barriers.
  • No jitters like you get from caffeine.
  • Works quickly after taking it.
  • Gluten and soy-free, and certified vegan.


  • None worth mentioning.

Our Thoughts:

If you’re seeking a drug-free way to enhance your performance and build a more muscular physique, Shroom TECH Sport is a top-notch choice. It easily outperforms having a couple of espressos before your workout.

Perfect Keto Perform Pre-Workout Powder


When it comes to an energy boost with low carbs, Perfect Keto Perform Pre-Workout Powder is as good as it gets. I’ve been subscribed to this product for over 2 years now, and it has consistently delivered outstanding results.

While it may not be the most budget-friendly option, the subscription plan provides a generous extra 15% discount.

With 7.7g of BHB, 5g of MCT, BCAA, creatine, L-citrulline, beta alanine, and green tea caffeine, you’re essentially hitting two birds with one stone – you can crush your workout sets while also boosting your ketone levels.

What’s even more crucial is that it contains less than 1g of carbs, so you don’t have to make special dietary adjustments on your gym days.

Another significant advantage is that it helps replenish essential minerals and electrolytes, including magnesium, calcium, and sodium. These are especially important on a keto diet when balancing fat and carbs with vitamins and minerals can be challenging.

The lemon flavor of this formula is delightful without being overpowering. You can easily drink a full glass of it before your workout without needing to hold your nose.


  • Helps you perform at your best to achieve weight loss goals.
  • Free from additives or fillers.

Additionally, this formula incorporates performance-enhancing elements like CDP-Choline, which promotes sharp mental focus during training and gym sessions. This mental clarity helps you stay dedicated and motivated throughout your entire workout.

Tailored for low-carb diets such as the ketogenic diet, this pre-workout supplement supplies your body with MCTs and BHB salts, encouraging your body to utilize fat stores for energy.

Sheer Strength Ketogenic Pre-Workout Supplement


The name of this ketogenic pre-workout supplement pretty much says it all. Sheer Strength is designed with the high-performance athlete in mind, someone who demands peak performance in every single training session.

However, it’s not just about enhancing performance; this supplement includes precisely what a keto dieter needs: ample electrolytes, minerals, L-Citrulline, and zero carbs.

The L-Citrulline in this formula plays a crucial role in boosting performance by promoting improved blood flow and energy delivery to your muscles. You’ll undoubtedly notice the difference from the first time you take it.

The addition of BHB salts is essential for replenishing lost electrolytes, both due to your training and the ketosis process. Staying well-hydrated is paramount to ensuring your mind and body operate at their best.

Similar to the other two pre-workout formulas we’ve reviewed, this one provides all the necessary elements to help you maintain motivation and focus throughout your training.


  • Supplies essential antioxidants and electrolytes.
  • Supports endurance, focus, and drive.
  • Contains BHB salts.


  • The taste may not be great, with a lingering aftertaste.
  • Doesn’t provide the same level of boost as the first one on this list.


Simply dissolve one scoop in 8-10 ounces of water and enjoy. The crushing punch flavor adds a punch to your gym session and some flavor to the mix.

Our Thoughts:

Sheer Strength Pre-Workout Powder is an effective keto pre-workout option, especially if you’re following a low-carb diet. It’s also available in a caffeine-free version, but for demanding training sessions, that extra ingredient can help you stay focused

Cellucor C4 Pre-Workout


My final recommendation is Cellucor C4 Ultimate, and I must emphasize from the outset that this product is specifically designed for high-performance athletes looking to enhance energy, endurance, and mental performance precisely when they need it most.

You won’t require this every day, perhaps not even every week, but for those grueling workouts where you’re truly pushing your limits, it will provide the extra physical and mental strength you require.

Each scoop of Cellucor C4 Ultimate contains 6g of citrulline malate and 1.5g of creatine nitrate, which significantly contributes to muscle pumps. You’ll be pleasantly surprised at how easy it becomes to increase your reps or add more weight, ultimately expediting the bulking process.

With zero grams of sugar or other carbs, it becomes much simpler to adjust your daily meal plan. Having some flexibility for extra carbs in your diet can be a bonus, so why allocate them to your supplements?

Lastly, you’ll appreciate the various flavors and the ease with which it mixes. It comes in Cherry Limeade, Icy Blue Razz, Orange Mango, Sour Batch, and Strawberry Watermelon flavors, offering you a variety of tasty options without the need for a blender to achieve the perfect mix.


  • Exceptional formulation featuring patented ingredients.
  • Provides outstanding energy, endurance, and pumps throughout your entire training session.
  • Available in a range of delicious flavors.
  • Boosts mental energy, providing significant motivation.


  • Comparatively expensive compared to other options.
  • Requires 45 to 60 minutes to provide the full boost, so timing is crucial.


Mix one scoop with 10 oz of water and shake well. Take it 45-60 minutes before your workout session, ideally timed for when you hit the high-intensity portion of your training after your warm-up routine.

Our Thoughts:

For maximum performance and endurance, Cellucor C4 Ultimate is truly unbeatable. The combination of ingredients works exceptionally well, allowing you to power through the toughest phases of your training. While it may not be the most budget-friendly option here, it’s a game-changer for those high-intensity days when you need that extra edge to excel.

Exploring the Optimal Timing for Carbohydrate Intake in Relation to Exercise

In the pursuit of achieving our fitness and weight loss goals, the question of when to incorporate carbohydrates into our workout routine remains a subject of ongoing discussion and consideration. This is a valid concern, as no one wants to risk disrupting their hard-earned state of ketosis due to unintentional carbohydrate consumption.

Let’s delve deeper into the intricacies of this matter:

Carbohydrates Before Exercise: For individuals involved in high-intensity activities such as demanding cardio sessions, weightlifting, or rigorous CrossFit workouts, the concept of consuming carbohydrates approximately 30 minutes before the workout holds significant appeal. The rationale behind this approach lies in the heightened demand for glucose that muscles experience during intense exertion, with carbohydrates being the most efficient fuel source to meet this demand. However, it’s important to emphasize the term “intense” here. If your workout falls closer to a 4 or 5 on the intensity scale of 10, you may not require a substantial carbohydrate intake, as your body may not completely deplete them.

Carbohydrates After a Workout: Post-exercise carbohydrate consumption primarily focuses on optimizing muscle recovery and growth. When combined with an appropriate amount of protein, these carbohydrates provide the ideal opportunity for achieving a lean and well-defined physique, especially if that’s your fitness goal. If you engage in high-intensity workouts but neglect to replenish your muscles with the necessary carbohydrates and protein, you may encounter a plateau in your progress.

Ultimately, the decision to consume carbohydrates before or after your workout hinges on the intensity of your exercise routine and your specific fitness objectives. Experimentation and tuning in to your body’s cues are key in determining the optimal approach within the context of a ketogenic diet.

So, Which Pre-Workout Supplement Stands Out?

When it comes to enhancing your gym performance, the market offers a plethora of options. However, among the supplements we’ve explored, one clear standout rises to the occasion: Onnit Shroom TECH Sport.

Whether you’re following a keto diet or not, Shroom TECH is compatible with various dietary choices. Its thoughtfully crafted ingredients deliver metabolic enhancements without introducing excess carbs or calories into your system.

Onnit has built a solid reputation for creating premium supplements that undergo rigorous scientific formulation and testing. Shroom TECH Sport is far from being just another caffeine pill disguised as a performance enhancer.

Instead of solely relying on your trusty espresso machine, consider incorporating Onnit Shroom TECH Sport into your pre-workout regimen. It’s a legitimate option that can provide a performance boost comparable to what you may have once associated with banned substances. Your fitness journey will undoubtedly benefit from this choice.
