Pre-workouts are popular supplements that help increase your energy levels and improve your athletic performance. They are stimulants that are meant to give you a burst of energy for even the toughest workouts, promote fat burn, and give you that extra push when you need it the most. 

There is something for everyone with a myriad of different types of pre-workouts on the market. Whether you’re vegan, a carnivore, or following a keto diet, you’ll be able to find a high-quality pre-workout supplement that will help you reach your fitness goals.

Best Keto Pre-Workout For Maximizing Muscle Growth on the market in (July. 2022)

What Is Keto Pre-Workout?

A keto or ketogenic pre-workout supplement contains a low or zero-carbohydrate stimulant formula that provides you with a burst of energy while keeping your blood sugar low. Since there are no (or a negligent amount) carbs and sugars, your body doesn’t produce insulin[1] as a response, thus keeping your blood glucose levels in check. 

When it comes to macronutrients and their roles in the human body, carbohydrates are the preferred source[2] of energy and fuel. Once they’re not available, your body either creates glucose by breaking down protein or starts utilizing fat for fuel. The latter[3] is also known as a state of ketosis. Those following a ketogenic diet are always on the lookout for keto-friendly products and supplements as they still want to be able to use them without an insulin response. 

Why Should You Take a Keto Pre-Workout Supplement?

First and foremost, taking a pre-workout supplement is definitely not a requirement or something everyone should take. It’s a product that helps you maximize your fitness goals by providing you with an energy kick that can boost your performance and motivation, making you push harder during your workout sessions. 

Additionally, you can always try to get an energy boost from keto-friendly foods before your workout and avoid the supplements altogether. Some people find that taking a pre-workout supplement is more convenient for their schedule and daily routine as they don’t have the time to make a keto pre-workout meal or even get a keto pre-workout snack, making a keto pre-workout supplement a perfect way to help them increase their endurance and work towards achieving their fitness goals.

With clinical studies[7] to back up their claims, their formula helps improve your athletic performance, increase your endurance, and promote a higher training volume. 

Onnit Shroom Tech SPORT contains powerful ingredients such as Cordyceps sinensis, Rhodiola, ashwagandha, green tea extract, and methyl B-12 which are studied[8] for their effect on one’s athletic performance, endurance, and energy levels.  

Additionally, some of these ingredients such as ashwagandha and Rhodiola, are known as adaptogens[9], or compounds that help reduce inflammation, stress hormones, and stress-related damage. They also help improve your cardiorespiratory endurance[10] or VO2 Max.

Its formula is powerful and contains 150 milligrams (mg) of caffeine, one gram (g) of creatine nitrate, 1.6 grams of beta-alanine, and a potent energy-boosting blend that helps increase your energy levels and maximize your time spent exercising. 

It’s not the cleanest product on the market as it contains some artificial ingredients and sweeteners known to cause potential adverse health effects in some people. On the other hand, those who like it and report no digestive discomfort to speak of may think about choosing it as a pre-workout. Since it contains no sugar, it’s suited for those on a ketogenic and low-carb diet, helping you lose weight, burn fat, and maintain lean muscle mass.

All of these ingredients combined create a powerful energy response in your body, supplying you with fuel to increase your strain during your workouts and get one step closer to your fitness goals.

It’s important to note that although the formula seems great, it does contain some artificial ingredients and sweeteners that might cause digestive distress or blood sugar problems, so pay attention to how you feel after drinking it.

It’s one of the affordable keto-friendly pre-workouts, but it does contain some artificial sweeteners and ingredients which might cause digestive discomfort and potential blood sugar problems. 

Benefits of Keto Pre-Workouts

Keto pre-workout supplements help provide you with additional energy without the carbohydrates. Their formulas efficiently increase the production of adenosine triphosphate (ATP) in your cells by utilizing fat for fuel and stimulating the use of ketones with powerful compounds such as caffeine, MCTs, and BHB. 

Additionally, most of these keto-friendly pre-workout formulas contain other powerful ingredients such as branched-chain amino acids, beta-alanine, creatine, and adaptogens that can help increase muscular strength and performance, aid in fat burn and weight loss, as well as lower your stress hormones, and improve recovery post-workout sessions. 

Choosing The Best Keto Pre-Workouts

The best keto pre-workout supplements contain a powerful formula that will help you stay in ketosis while supplying you with the necessary energy boost to improve your exercise endurance and help you push through even the hardest workout routine. 

When choosing the best pre-workout supplement, there are a few factors to consider:

  • Zero or extremely low sugar – if you’re looking to stay in ketosis, it’s important to make sure your pre-workout is low in carbohydrates and sugars. If you can choose one that contains zero of both, that would be even more preferable.
  • No artificial ingredients – to minimize the risk of any potential digestive issues or reactions, try to choose a pre-workout that does not contain any artificial ingredients, fillers, colors, or sweeteners
  • Added BCAAs – pre-workout products that contain an additional amino acid blend help promote muscle growth and weight loss
  • Other powerful ingredients – many pre-workout dietary supplements contain additional ingredients that can help reduce your inflammation, improve recovery, protect your digestive health, and increase exercise endurance
  • No jittery side effects – if you’re sensitive to caffeine, look for those pre-workout products that don’t have high caffeine content. Limiting your caffeine intake will help prevent the jittery feelings[14] people sometimes get with pre-workouts. 

The Bottom Line

Keto pre-workout supplements are great additions to your diet that help fuel your workouts and give you that extra energy boost when you need it the most without causing a sugar rush. Although they aren’t necessary for a good-quality workout, they are a great tool you can use when your motivation is low, and you feel like you need something to push you through your fitness routine. 

Frequently Asked Questions

Is using keto pre-workout supplements safe?

Yes, using keto pre-workout supplements is safe to consume, but those sensitive to caffeine or specific artificial sweeteners need to ensure they’re not overdoing it. Caffeine can cause jittery sensations, and artificial sweeteners can cause digestive discomfort.

Does keto pre-workout cause weight gain?

No, pre-workout supplements, in general, do not contain a lot of calories, especially those with zero carbs and zero sugar.

Does keto pre-workout help gain muscle?

Yes, especially if it contains added BCAAs that promote muscle growth and aid in recovery. The goal of a pre-workout supplement is to increase your fitness performance and help you build strength and endurance.

How many carbs are in keto pre-workout?

Ketogenic pre-workout supplements usually contain zero carbs or a very negligent amount which won’t kick you out of ketosis or even have the slightest impact on your blood sugar levels. Keto diets allow up to 50 grams of carbohydrates[15] per day (equating to 200 calories[16]), with most people consuming around 20 grams of carbohydrates per day.

Why does keto work?

The ketogenic diet is extremely low in carbs, which signals your body that it needs to start utilizing a different source for creating energy. The goal is to start using fat for fuel and therefore lose weight and body fat.
