We all know Red Bull, and most energy drinks for that matter, aren't good for you, but of all the kinds of Red Bull you can get this is probably the best option in terms of risk vs reward. It has good flavor despite not having that same carbonation-type kick that regular Red Bull has, and definitely gives you energy. And in comparison, it has significantly less calories and carbs. If you're going to reach for a Red Bull, this is the best option!

I absolutely despise diet soft drinks/energy drinks and all sugar free versions. The sugar substitutes have such a nasty aftertaste: I can't stand it. This is THE ONLY sugar free beverage I have ever enjoyed. The classic bubblegum flavor somehow overpowers the sugar substitute flavor. Love!

I love sugar-free Red Bull. I am 37 years old now but I remember drinking two of these for breakfast my senior year of high school, and killing the day. The taste is fantastic, it gets the job done, and it's affordable. Maybe a little too effective, I would limit the caffeine, I don't want anyone's heart to explode.

Balance a busy workday with an energy boost from Red Bull sugar-free energy drink. Boost energy and concentration with this energy drink. B-group vitamins help increase energy and support the metabolism while caffeine stimulates cognitive function. This Red Bull sugar-free energy drink has the same quality ingredients as the original but without sugar.

Love! Still the same great energy effects as Red Bull, just without the extra sugar. Tastes pretty much the same as the version with sugar. Doesn't make me crash, and tastes great. Definitely recommend for people who are mindful of their sugar intake like I am!

Need a boost and get wings, this is my go to beverage. All the caffeine without the sugar. You get the boost with less of a crash. 20 oz might be a lot. Use with caution if you're sensitive to caffeine. If not, go for it. Lifesaver for all those late nights studying.

When I started college I hated coffee, but kept hearing about energy drinks that help a ton when studying. I tried various options, but when I got to Red Bull's sugar free can, it was love at first sip and nutrition fact section. Even without gaining weight, it gave me lots of focus and allowed me to stay on the Dean's List for 6 semesters straight!

I like to keep it simple and stick with the classics haha, so Sugar Free Redbull is a staple for quick energy. I'm more of a coffee drinker, but sometimes ya just need a little extra and I love the flavor! It's the best tasting diet energy drink, in my opinion.

Hands down the best Red Bull on the market! It's sugar free and probably still considered bad for you but it gets the job done! Great price and packaging and very effective- I was going on 24 hours of no sleep on a travel day and Red Bull help me get through it!

This is my go to energy drink if I need an afternoon boost but am not in the mood to make a coffee. I like the sugarfree version, it has the same taste, nothing off. I like to drink it pure out of the can or sometimes stretch it with bubbly water as it tastes sweet. I usually don't mix it with anything else but in the past have - vodka. And it was good. I really enjoy the full taste at no sugar with some boosting effect. Highly recommend!
