I’m a big fan of the keto diet and have seen some impressive results with several clients. But 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 make pre-workout on keto diet a lot easier decision.
Let’s find out what the best keto pre-workout supplements on the market offer.
Our Top Keto-Friendly Pre-Workouts

Onnit Shroom Tech Sport is one of the most natural pre-workout supplement options we could find.

2 - Cellucor C4 Original Pre-Workout
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. It also has some added vitamins that may help with muscle recovery and repair.

This is perfect for keto dieters 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.
3 - BPI Sports Ketogenic Pre-Workout
BPI doesn’t just claim to boost energy levels during your workout, but it also could be an option to increase your ketosis.
This could be a benefit, especially during the initial phase of the dreaded keto flu.
Just keep in mind that it’s not a good idea to take this pre-workout later in the day due to a strong caffeine dose.

4 - Sheer Strength Pre-Workout
The name does suggest that it’s aim is to boost energy, and I did find many positive comments online.
Of all the keto pre-workouts we tried, this seemed to be one of the fastest working ones.
The only downside is that it’s not available in a large range of flavors.
- 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
- A moderate amount of caffeine for lower chances of jitters
- Some more flavor options would be great
It is recommended to take this pre-workout 20 to 30 minutes before your training as it's considered one of the fastest working keto pre-workout supplements.
5 - Kinobody Octane Pre-Workout
Kinobody was a new one for me, and with no calories from carbs, it’s an obvious favorite for keto dieters.
Aside from the added energy this pre-workout claims to provide, you might also notice some added fat burning effects from the caffeine, which may be best if you’re looking to lose some weight with your workout routine.
- Zero-calorie option to not mess up any part of your diet efforts
- Added L-theanine may help with focus and mental performance
- Contains natural caffeine to reduce jitters and crashes
- Nice selection of fruity flavors
- A larger tub and bulk discounts would be nice
While it does seem to work well, I couldn’t find bulk order options to save some money. However, you can take advantage of their 60-day money-back guarantee if you are unsatisfied for any reason.
Common Keto-Friendly Ingredients
There are plenty of pre-workout supplements that are heavily reliant on things other than essential amino acids. In many cases, the pre-workout powder is full of carbs, which makes them less than suitable for anyone on the ketogenic diet.
But what might actually work for you?
Here are a few things to look out for.
1 - Caffeine
Yes, caffeine may be an ideal ingredient as it could provide you with mental focus, motivation, and some fat burning effects, especially when coupled with an effective workout in the gym . 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
There have been several interesting studies that revealed that the effects of caffeine could be improved with theanine .
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 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
One very extensive study has revealed that strength and endurance may improve during resistance training through creatine supplementation . 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 towards 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
While vitamins may not play a direct role in strength and endurance, there is plenty of evidence that they help maintain lean muscle mass as well as exercise recovery . It’s certainly not something to be ignored, especially during an intense workout.
Let me guess what your next question is.
Benefits Of Keto Pre-Workouts
The benefits of a keto pre-workout go beyond energy, endurance, and a boost in muscle or workout performance. See, the above ingredients are also commonly associated with the ability to burn fat to release more ketones.
This is especially interesting to anyone trying to lose weight or gain more muscle definition through a cutting phase.
But there is also the aspect of improved blood flow, which has several effects. First of all, it will deliver more oxygen and ketones throughout your body, which helps with strength levels. But it could also get you those improved pumps, which helps to show off all your hard work.
Here's a great video on a DIY keto pre-workout drink:
Potential Side Effects
Pre-workout side effects are pretty rare when it comes to keto products, and in most cases, it may come down to allergies or people taking too much of a product in one go.
While they are generally suitable for taking over longer periods of time, you should avoid taking huge doses of pre-workout. The reason is that some of the fat burning ingredients, including certain types of protein, may be more difficult to digest.
Even though you may be used to higher doses on the ketogenic diet, you could still be facing some stomach upset.
Also, keep an eye on your caffeine intake to avoid jitters and insomnia.
There are 3 things that I always preach to my clients, and they are based on the great advice I received from dietitians over the years.
1 - Getting T
You want to ensure that you get your timing right so that you get the best results. Start by taking the pre-workout 30 minutes before exercise, and if you start feeling the effects before you begin your workout, then simply adjust the time next time around.
2 - Take The Right Dose, Not The Maximum One
Too many folks I’ve worked with saw some great results within a few trial routines only to think that taking larger doses helps even more. The problem is that there will be a plateau where you won’t perform better, and this approach might actually make you sick.
3 - Stack With Other Supplements
Don’t stop with a pre-workout supplement. You could be much better off also investing in some products with keto-friendly fat burning ingredients. This may help boost your levels of ketones, and at the same time, might get you to weight loss goals faster.
Is it safe to use keto pre-workout supplements?
Yes, it is safe to use keto pre-workout supplements, and in many cases, it could actually support your ketosis. Especially in the early days of keto, some of these dietary supplements might provide metabolic support and ketones to overcome the keto flu.
How long does keto pre-workout last?
The best keto pre-workout usually last for up to 4 hours. This will depend on your body’s ability to digest the ingredients as well as how tough your exercise routine is.
Does keto pre-workout make you gain weight?
No, keto pre-workout doesn’t make you gain weight, as it generally does not contain enough calories from carbs and sugar. It’s far more likely to help remove some stubborn love handles.
To be sure, choose a pre-workout that has no added sugars, flavors, or additives.
