Pre-workout supplements can improve your athletic performance by giving a boost of energy. That’s why they’re popular in the fitness community. My exercising journey started by taking pre-workout regularly, but I was always picky because some left me feeling jittery even after my workout.

What I love about Nuun is that these tablets dissolve easily and can be consumed before, during and after your run. They contain electrolytes, which are essential minerals such as magnesium, calcium, sodium and potassium that are found in our blood, urine and sweat. When you sweat you lose many of these minerals, which is why sometimes drinking water isn’t enough. I used Nuun consistently during my peak training runs and found they helped keep me going, no matter the distance. Nuun comes in a tube with 10 dissolvable tablets in flavors such as Berry Blast, Citrus Fruit, Fruit Punch and Lemon Line to name a few. These can be easily mixed with water and dissolve in less than two minutes. One tube costs about $8, which is on the cheaper end of the pre-workouts on this list.

Although it’s technically not marketed as a pre-workout, Nuun serves a similar purpose because it keeps your body hydrated and replenishes any electrolytes lost during your workout to prevent you from bonking out. I personally like that the brand offers caffeinated and non-caffeinated options, so there’s something for any active individual. I’ve tried both the non-caffeinated and caffeinated tablets without any issues, and found the caffeinated tablets work well as a pre-workout because they gave me the boost I needed prior to hitting the pavement.

Shifted is a pre-workout brand that prides itself on using science to back and develop its powder. It is available in a Maximum Formula Pre-Workout and Premium Formula Pre-Workout. Key ingredients include L-citrulline, beet root extract, creatine monohydrate and alpha-GPC, intended to give you energy and keep you focused during your workout. It also has 250 mg of caffeine. Additionally, the powders are sugar-free, gluten-free and soy-free. I tried Shifted’s Very Berry flavor in their Premium Formula pre-workout and was pleasantly surprised by the flavor. 

I mixed two-thirds of a scoop with water, and took it about 30 to 45 minutes before my workout. I appreciated that the drink had a pleasant berry flavor without the bad aftertaste. It also provided me with an adequate amount of energy that didn’t leave me feeling jittery after the workout or give me any negative side effects. At $40 for a jar, it’s on the pricier side, but if you’re looking for a pre-workout formula that does the job without any questionable additives, Shifted is a great choice.

I tend to gravitate towards berry flavored pre-workouts and Ascent’s Blueberry Raspberry hit the spot. It reminded me of the blue raspberry Jolly Rancher flavor, which was a favorite of mine as a kid. However, now that I’m older, I can only handle so much sweetness. I followed the directions on Ascent’s pre-workout bag and mixed one scoop of pre-workout with 10 ounces of water 20 to 30 minutes before my workout. I found the flavor to be super sweet, but it didn’t leave a bad aftertaste or upset my stomach. Next time I would do half a scoop to cut back on the sweetness. 

This pre-workout has 150 mg of caffeine, which gave me enough energy to complete my tough strength training workout and left me focused even afterward. It also features 250 mg of electrolytes, which is important to keep you hydrated as you sweat during your workout. At $35 for a 12.7-ounce bag, it’s priced fairly for those looking for a middle of the road option. I was happy that Ascent gave me the adequate amount of energy I needed to charge up my morning and workout.

What is a pre-workout?

Pre-workouts come in the form of a powder, are mixed with water and taken a half hour or up to an hour before a workout to help boost energy and performance.

Do pre-workouts have side effects?

Side effects are one of the reasons some people are hesitant to take a pre-workout supplement. Some may be sensitive to caffeine, which is a key stimulant in many products, while others may not respond well to other ingredients such as artificial sweeteners or sugar alcohols. Then there are those who have certain health conditions and are medically advised to avoid them altogether.
