I’m a big fan of the keto diet and have seen some impressive results with several clients. The science behind it is fascinating, to say the least; during ketosis, the body shifts into a fat-burning zone for energy which can enhance your exercise performance and boost your energy levels and endurance.

That said, it’s one of those diets where you cannot just grab random performance supplement products off the shelf. You simply cannot afford to mess up your ketosis.

Through some extensive product research and testing, we can now help make your pre-workout supplement on the keto diet a lot easier decision.

Let’s find out what the best keto pre-workout meal supplements on the market offer.

Onnit Shroom Tech Sport is one of the most natural pre-workout supplement options we could find. I remember when I tried it for the first time and I must say, the energy boost was noticeable and it felt clean and sustained, thanks to its natural ingredients.

Based on herbs and mushrooms, it claims to boost exercise performance while also providing important vitamins, which is why many people consider it the best for a ketogenic diet or any low-carb diet.

Pros and Cons

Pros

  • Has zero carbs or calories to mess with your ketosis
  • A good dose of vitamins C and B12 for muscle performance
  • A moderate amount of caffeine may support mental clarity
  • Available in some tasty and refreshing flavors as a pre-workout drink

Cons

  • Could be higher in creatine

If you’re looking for some increased blood flow for better pumps, then Cellucor C4 Original Pre-Workout seems to be a favorite with bodybuilders. In our testing phase, my clients and I noted a noticeable enhancement in workout intensity and the added vitamins that may helped with our muscle recovery and repair.

The brand has a line of different health supplements that are considered to be some of the best in the market. Their claims and the online reviews back this up well.

This is perfect for keto diet enthusiasts as it has zero carbs so it's a solid pre-workout.

While it does contain creatine, you may want to take an extra scoop of powder for a better dose.

Pros and Cons

Pros

  • Contains BHB salt to help raise ketone levels
  • Positive comments that it may work for weight loss
  • May start working in as little as 20 minutes to help lose weight
  • A moderate amount of caffeine for lower chances of jitters

Cons

  • Some more pre-workout drink flavor options would be great

The name does suggest that its aim is for an energy boost, and I did find many positive comments online.

Of all the pre-workouts we tried, this seemed to be one of the fastest-working ones. I still remember the quick kick of energy I felt after using it. And it wasn't just me, my clients noticed it as well. The fast reactions made the workouts efficient and more enjoyable.

The only downside is that it’s not available in a large range of flavors.

It is recommended to take these pre-workout supplements 20 to 30 minutes before your training as it's considered one of the fastest working pre-workouts.

  • Many reports about better focus and motivation
  • Zero calories from carbs and only 40 from fat
  • Nice flavors with blue lemon ice being very popular

Cons

  • Avoid taking later in the day due to a strong dose of caffeine

BPI doesn’t just claim to boost energy levels during your workout, but it also could be an option to increase your ketosis. I personally experienced a significant uplift in my energy levels during the testing phase. It made those intense workouts more manageable and productive as well.

Just keep in mind that it’s not a good idea to take these pre-workout supplements later in the day due to a strong caffeine dose.

This pre-workout is best taken in the morning for that extra energy during your workout sessions.

Common Keto-Friendly Ingredients

When scouting for keto-friendly pre-workout supplements, it's a jungle out there. Many are packed with carbs, a big no-no for keto enthusiasts. So, what's the real deal?

Let's dive in.

1 - Caffeine

According to studies published by the National Library of Medicine, caffeine can sharpen your focus and rev up fat-burning, especially when paired with a solid gym session [1]. Just make sure you avoid those options that have a strong enough dose to keep you awake all night.

The best caffeine supplement we've found is from a brand called Nutricost.

You may want to get try a caffeine-free pre-workout if you're too sensitive to stimulants.

2 - L-Theanine

Studies published by the National Institutes of Health have revealed that the effects of caffeine could be improved with theanine [2].

It tends to make you less jittery while still giving you a mental boost.

Even if you’re not on keto, this ingredient is the one to look for in your pre-workout supplements when you don’t like excessive caffeine stimulation.

The best L-Theanine supplement we've found is from a brand called Nature's Trove.

3 - Creatine

Extensive research, including a study from the Journal of the International Society of Sports Nutrition, shows creatine amps up strength and endurance in resistance training [3].

I would go as far as saying that it’s possibly one of the most suitable and keto-friendly pre-workout ingredients.

Research has shown that supplementing with creatine can increase muscle mass and improve strength when a person combines it with strength training.
Miho Hatanaka, Registered Dietitian

The best creatine supplement we've found is from a brand called Transparent Labs.

If you're trying to avoid creatine, you can get yourself a creatine-free pre-workout supplement.

4 - BHB Salts

My dietitian pointed me toward some interesting articles, and she mentioned that she recommends BHB salts to clients starting out on ketogenic diet. However, it may also help with better exercise performance in the gym.

The best BHB salts we've found is from a brand called Vitamin Bounty.

5 - Vitamins C and B12

As Medical News Today highlights, these vitamins are key players in muscle maintenance and recovery, especially after a grueling workout [4].

It’s certainly not something to be ignored, especially during an intense workout.

Here are the best vitamin C and the best vitamin B12 supplements we've found.

Let me guess what your next question is.

Benefits Of Pre-Workout

Pre-workout perks aren't just about upping your energy and muscle game. These power-packed ingredients are fat-burning champs, cranking out more ketones – a big win if you're eyeing weight loss or muscle definition.

Plus, they're all about boosting blood flow. This means more oxygen and ketones coursing through your body, ramping up your strength.

And let's not forget the killer pumps, making all your hard work visibly pay off.

Here's a great video on a DIY pre-workout supplements drink:

Potential Side Effects

Three different person experiencing side effects from Keto pre workout supplement

Side effects from keto pre-workouts are a rare breed, but they can sneak up on you.

Often, it's about allergies or going overboard with the dosage. Remember, moderation is key – too much, especially of those fat-burning ingredients, can upset your stomach. Even keto veterans aren't immune to this.

Hydration is your best friend here. Drinking plenty of water keeps everything running smoothly and makes the most of those ketones.

And watch your caffeine levels – too much might leave you jittery or wide awake at bedtime.

Pre-Workout Tips

I've got three golden rules for pre-workout success, straight from the dietitian's playbook:

  1. Nail the Timing: Timing is everything. Kick off with your pre-workout 30 minutes before hitting the gym. Feel the effects too soon? Tweak the timing next session. And remember, moderation wins with dosage – especially with BHB salts for that energy and focus boost.
  2. Right Dose, Not Overdose: Seen folks chase better results with bigger doses – bad idea. There's a limit to how much your body can take before it backfires. Stick to the recommended dose to stay on the safe side.
  3. Mix and Match Supplements: Don't just stick to one pre-workout supplement. Spice it up with other keto-friendly options that fire up fat burning. It's a smart move for upping ketones and speeding towards your weight loss goals.

10 thoughts on “The Best Keto Pre-Workout Supplement
Low-Carb Friendly Drinks

  1. I’ve been following Kinobody’s YouTube channel for a while now and love his approach on living a healthy life. I was on the fence about trying Octane but after reading all the reviews I knew it was worth a shot. The first time I took it, I noticed an instant boost of energy and focus.

  2. I’ve been taking BPI Sports for about a year now. It is the best keto pre-workout supplement I have found. I can see the benefits immediately after having it. The energy & focus are fantastic, and the mental clarity is something you only find in keto supplements. I would recommend this to anyone who needs energy without all the jitters.

  3. As a fitness professional, it’s important to me that I know what I’m putting into my body. This is why I use Kinobody Octane for all of my workouts. Octane has the best fat-burning ingredients out there and doesn’t leave me feeling jittery like other products do. Plus, it tastes amazing!

  4. I’ve tried tons of pre-workouts in the past, but nothing compares to BPI Sports’ Keto Pre-Workout. It is hands down the best keto pre-workout out on the market right now. It doesn’t crash my system like some other brands and I can feel it all day.

  5. I have been using Onnit Shroom for months now. I was using other keto supplements but they don’t do anything for me anymore. Onnit Shroom is the best pre-workout supplement I have ever taken. It gives me energy, it clears up brain fog, and it helps with my workouts.

  6. I am absolutely in love with Onnit Shroom. I recently went on a Keto diet and was looking for a product to help me get through my workouts and help me feel energized. I tried tons of different products and they all tasted really bad or didn’t work at all.

  7. I’m new to keto and have just returned from a fasting heavy leg workout that I began after my summer trim and endured. I’ll definitely give these keto pre-workout supplements a shot!

  8. THANK YOU SO MUCH! I’m new to keto and have just returned from a fasted heavy leg workout that I resumed after my summer cut and endured. I’ll definitely give these a shot! Is c4 pre workout keto friendly? You definitely answered my question. Turns out, it is a great all-around pre-workout (it contains 150mg caffeine for an energy boost, a small amount of creatine (1g) per scoop, and some other ingredients that are said to promote a good workout or muscle building, such as Beta-Alanine, Arginine, and Theacrine).

  9. Sheer Strength is by far the best Keto friendly pre-workout supplement. If you’re looking for a product with zero carbs and sugar, this is it. The low-carb options are great and there is no crash after you’ve taken it! I’m so glad I found this company because of their keto friendly drinks, which are also very tasty!
