KEYKetone Energy Drink : Sugar Free, 80mg Low Caffeine, All Natural, 11.5g Ketones, Long Lasting Energy, Green Tea & L-Theanine for Mental Focus, Ginger Lime (Pack of 12)

Drinking KEY has completely changed the game for my everyday routine. Instead of the over-caffeinated feeling I used to get from coffee or other drinks, it gives me steady focus that actually lasts. It feels more like my brain is just on and ready to take on everything I need to do. Most mornings, I drink a can before class or when I’m at work—it’s my way of easing into the day without depending on coffee. On slower days, I’ll have one in the afternoon for a mental boost that won’t mess with my sleep schedule. Sometimes I even drink one while studying—it feels like a treat but actually helps me stay focused.KEY isn’t like the typical energy drinks I’ve tried. It lets me lock in and stay focused throughout the day without making me jittery or causing a crash later. That smooth feeling is honestly rare. It’s a bit pricier than other options, but I think it’s worth it because it helps me stay productive and balanced—not just wired. For me, it’s more than a quick pick-me-up—it feels like real support for getting through busy days without throwing off my mood or sleep schedule.

I’ve tried a ton of energy drinks and was honestly skeptical about a “ketone-based” one, but the KEY Ketone Energy Drink blew me away. The Ginger Lime flavor is light, refreshing, and not overly sweet, which I really appreciate. There’s no weird aftertaste like some other sugar-free drinks.I love that it only has 80mg of caffeine—just enough to give me a mental boost without making me jittery. The green tea and L-theanine combo definitely helps me stay focused, and the energy lasts longer than I expected. No crash, no headaches, just a clean, steady pick-me-up.Also, huge bonus that it’s all-natural and sugar-free. I drink one before workouts or in the mid-afternoon when I need to power through emails. Definitely becoming a staple in my routine!

The grapefruit peach key energy drink flavor is one of the best energy drinks I’ve ever purchased! The flavor isn’t crazy artificial like most energy drinks I’ve had, and it tastes refreshing. This drink is perfect if you want a light beverage, but something that can keep you going throughout the day. Another pro of this drink is that there is ZERO sugar, which is nice for someone who is choosing a low sugar lifestyle or diet. The energy boost from this drink is unique compared to other brands considering I didn’t crash a hour after drinking it. This drink is definitely something that I will input into my everyday life, and Amazon grocery rotation. I can’t wait to try the other flavors!

Key Ginger Lime is an excellent choice if you want a clean, sugar free, balanced energy drink with moderate caffeine and supportive ketones. It excels in providing smooth and sustained energy, with green tea elements that elevate focus without anxiety. The flavor is fresh and zesty, though those sensitive to ginger or calories might take pause. For anyone seeking a healthier pick-me-up, it’s one of the best natural energy options out there—especially if you value sustained alertness over caffeine jolts. It is best for wellness-minded individuals and focus seekers like college students while avoiding sugar and high-stimulant energy drinks.

KEY gives me clean, focused energy without the jitters or crash. Unlike other energy drinks that spike and drop, KEY feels balanced — I stay sharp for hours. I use it most mornings instead of coffee, and sometimes before workouts or meetings. It boosts my mental clarity without affecting my sleep later. Compared to other energy drinks I’ve tried, KEY tastes better, feels more natural, and doesn’t upset my stomach. It’s slightly more expensive, but totally worth it for the performance. If you want long-lasting energy without the downside, KEY is easily the best option I’ve found.

This stuff is great. I rarely reach for energy drinks, but these interested me because of their 'natural' element. The ginger lime flavor is awesome, it reminds me of ginger ale, although it does have an interesting aftertaste. But the energy element of these is what I really loved about it. I did not get jittery feelings or have any sort of crash or tiredness afterwards-like many other energy drinks do. I love using these as a pick me up in the afternoon, or while on a long drive because it helps me stay awake and focused.

Me and 2 friends each took like 3 sips and we all felt our heart pumping really weird, it was a weird sensation, i dont know if thats what a heart attack feels like but i dont ever wanna try this drink again. Ive drank other energy drinks like red bull and monster and never got such a weird sensation with this energy drink.Edit: I will say that even though i didnt enjoy the energy drink, this company’s customer service is on point. They gave me a full refund and were very easy to communicate with. Extra star.

KEY energy drinks left me feeling non-jittery in the morning but awake. It was truly the perfect amount of caffeine for me. I love drinking my KEY in the morning with breakfast as flavors compliment my meals well with their natural taste. It is also the perfect afternoon pick-me-up. The taste was also the perfect amount of sweetness too as I find many other energy drinks feeling too artificially sweet. In comparison to other energy drinks overall, this is just way better by far. It is the perfect amount of caffeine to get me going in the morning at 80 mg versus the traditional 200 in many energy drinks that has often left me fearful for the state of my heart. The value for the money was also fantastic and comparable to other brands. I would definitely buy again!
