Fast Twitch is Gatorade's energy drink. The brand advertises that it has electrolytes, zero sugar, and caffeine “to help athletes focus the mind and power the body for athletic performance.”
But does Fast Twitch contain an effective dose of caffeine for improving workouts? What about an effective dose of electrolytes? Does it contain any unhealthy ingredients? And what was our honest experience purchasing and trying this product?
In this article we’ll answer all of these questions and more, as we analyze the ingredients in Gatorade Fast Twitch to give our take on whether or not it’s likely to be effective for enhancing athletic performance, and whether or not it's healthy.
We'll also share our honest experience using this drink as a pre-workout, and explain if there are healthier Gatorade options.
Key takeaways:
- Contains an artificial sweetener
- Contains two other inactive ingredients we consider unhealthy
- We consider Gatorade Fast Twitch to be unhealthy
Ingredient Analysis
The ingredients in Gatorade Fast Twitch Cool Blue flavor are shown below:
Caffeine is the most important ingredient in most energy drinks, and Fast Twitch provides a 200 milligram (mg) dose.
A medical review published in the Sports Medicine journal found that caffeine improves power and reduces physical fatigue, and the dose in Fast Twitch is within the effective range.
Caffeine was also shown to reduce mental fatigue in a meta-study published in the Nutrients journal. Most of the clinical trials analyzed used a dose of around 100 mg.
Fast Twitch contains two electrolytes according to its Nutrition Facts label: sodium and potassium.
Sodium is included at a dose of only 160 mg, or 7% of the Daily Value (DV). While better than nothing, an elite athlete may need vastly more than this to recover what’s lost through sweat.
Potassium is included at only 50 mg, which is less than 1% DV.
There are three inactive ingredients in this drink that we consider to be unhealthy.
Sucralose is an artificial sweetener, and is what’s used so that Gatorade can claim “zero sugar.”
A clinical trial published in the Nutrition Journal found that sucralose had a negative impact on insulin levels in healthy adults.
Citric acid is a flavor enhancer and preservative that can cause whole-body inflammation in some individuals, according to a medical review published in the Toxicology Reports journal.
Natural flavor is a broad descriptor that fails to identify the specific flavoring compound(s) used.
As we documented in our review of Gatorade Zero ingredients, some natural flavoring compounds and their metabolites may have toxic effects according to clinical studies.
Overall we consider Gatorade Fast Twitch to be unhealthy because of the use of an artificial sweetener, citric acid and natural flavor.
We Tested Gatorade Fast Twitch
As the author of this article, I wanted to try Gatorade Fast Twitch myself to share my thoughts on the taste and effects.
I purchased the Cool Blue flavor from my local Walmart, and while I thought it tasted acceptable for a sports drink, the artificial sweetness made it taste worse than regular sugar-sweetened Cool Blue Gatorade to me.
I used the product about 30 minutes before working out.
I didn't notice any increased strength or performance benefits from using this energy drink like a pre-workout. Perhaps it would be better for cardio, but for strength training, I didn't enjoy any benefits.
I didn't feel like the drink gave me much added energy or focus. Surely it provided a slight boost in focus due to the caffeine, but I personally find that naturally-caffeinated drinks like coffee provide a much bigger mental boost for the same caffeine content because coffee contains other stimulants like theobromine.
I would not purchase this product again as I didn't like the taste or effects, and I don't like drinking commercial sports drinks with so many additives.
Overall, I would rate Gatorade Fast Twitch 1.5 out of 10.
Which Gatorade Product is Healthiest?
Gatorade sells a wide variety of different sports nutrition and energy drinks with different benefits.
As we documented in our review of Gatorlyte ingredients, all three of Gatorade’s most popular drinks (Gatorade Original, Gatorlyte and Gatorade Zero) contain artificial food dye in some of their flavors.
Artificial food dyes were shown in a 2012 medical review to have a wide range of negative health effects, and the researchers even concluded “that all of the currently used dyes should be removed from the food supply and replaced, if at all, by safer colorings.”
Because Gatorade Fast Twitch is free of artificial food dye (and uses whole food colorants like blueberry juice instead), we consider it to be a healthier option than most Gatorade products, and it’s a good thing that Gatorade seems to be moving in a more natural direction with their formulations.
But the healthiest Gatorade product in our opinion is Gatorade Organic. Its ingredients are shown below:
While it does contain citric acid, it’s free of artificial sweeteners and includes organic natural flavor rather than natural flavor.
We have no issue with organic natural flavor as it’s derived from organic, whole food ingredients according to USDA guidelines.
