When you step into a fitness class or weight room, it’s a rare sight not to find a floor strewn with colorful drinks in shaker cups. What’s inside? Usually a fruity and sweet pre-workout drink.
A pre-workout supplement – more commonly known as a pre-workout – contains a variety of ingredients said to improve your athletic performance during workouts. Taken about 30 minutes before you exercise, a pre-workout can make the difference between setting new personal bests and crashing halfway through.
Despite the flashy label and big claims, not all pre-workout ingredients are created equal. Let’s take a look at the best keto pre-workout supplement ingredients and the ones to avoid.
Best Keto Pre-Workout Supplement Ingredients
The following ingredients aren’t just keto-friendly; they have all been shown to significantly improve your athletic performance during your workout.
Beta-Alanine: Famous for the tingling it causes in your neck, beta-alanine has been shown to support intra-workout strength and performance. One study found that beta-alanine dramatically improved power output during a workout. 
Caffeine: No pre-workout is complete without good-ole caffeine. This stimulant can support both your physical and mental performance. Studies show that caffeine improves high-intensity performance allowing you to kick butt during a high-volume workout. Whatsmore, studies show that it enhances cognitive performance and focus. 
Creatine: It’s not enough to give yourself a mental pick-me-up during workouts; your muscles also need fuel. Muscle tissue loves adenosine triphosphate (ATP), especially during weightlifting. Creatine monohydrate is converted into ATP, supplying you plenty of usable and bioavailable fuel during workouts. Creatine has been shown to promote “significantly greater gains in strength, fat-free mass, and performance primarilyhigh-intensity exercise tasks.” 
Citrulline Malate: A non-essential amino acid, citrulline malate is an excellent vasodilator, making it a must-have for those chasing a pump during workouts. Citrulline is converted into arginine, which is used to create nitric oxide. Citrulline has been shown to enhance exercise performance, especially during weight training workouts. 
Exogenous Ketones: What’s a keto-friendly workout without ketones? Exogenous ketones can do more than keep you in a state of ketosis. Studies show that exogenous ketones are a readily available form of fuel for your muscles. When taken with the ingredients above, exogenous ketones are ideal for all types of workouts. 
Be on the Lookout For these Ingredients
Naturally, if you’re following a ketogenic diet, the last thing you want to introduce into your diet is simple carbs. But if you’re not careful, that’s exactly what you’ll get with certain pre-workout supplements.
Check the label of the pre-workout you’re considering. If you find “dextrose” or “fructose” on the ingredient label, look elsewhere.
These two simple sneaky carbs are used as sweeteners or as a quick-access fuel since glucose is an effective source of energy for those not following the diet. For you, dextrose and fructose can knock you out of a state of ketosis.
