Ketone Drink - Ketones for Energy & Focus, Sugar Free & Low Caffeine from Green Tea with L-Theanine, No Crash or Jitters, All Natural, Lightly Carbonated, Pineapple Passionfruit (Pack of 12)

I had a really great experience with KEY!!! The flavor was super fruity and fresh without being overly sweet, which I loved right away. Especially for a 9am yoga sculpt class when you dont want to have a whole 200mg energy drink and others can become to overpowering. I also appreciate that it only has 80 mg of caffeine because it gave me a smooth, noticeable energy boost without the jitters or crash I sometimes get from coffee or other energy drinks. The ketones made a big difference for me, especially with mental focus and workouts. It helped me feel more clear, motivated, and steady throughout the day. I’ve even started using it as a replacement for my morning or afternoon coffee since the energy feels much more sustained and clean, and the fact that there’s no sugar is a huge plus. Compared to other energy drinks, KEY just feels lighter and more balanced while still being effective, so it’s definitely a 5-star experience for me.

As a college engineering student, my schedule is pretty chaotic with long lectures, labs, studying, and trying to squeeze in workouts when I can. I used to depend a lot on coffee, but it honestly made me feel shaky or I’d crash right when I needed to focus the most. I started drinking KEY mostly out of curiosity, and what I noticed first was how different the energy felt. The ketones give me a steady boost that helps me stay focused during long homework or study sessions without feeling wired. I’ve actually been reaching for it instead of coffee in the mornings & afternoons because the energy feels smoother and lasts longer. It’s also been nice before workouts and I feel more motivated and don’t feel drained halfway through. Compared to other energy drinks I’ve tried, I like that there’s no heavy sugar crash and no jitters. It just feels like more consistent energy and clearer focus, which honestly helps a lot when you’re trying to keep up with engineering classes. Definitely not a magic fix for being tired, but it’s been a helpful part of my routine lately.

As a busy college student athlete, I’m always looking for something that helps me keep up with workouts, classes, and long days without feeling burned out. KEY has been a great addition to my routine. The ketones give me a clean energy boost that helps me feel focused during training and more dialed in mentally for school. I’ve started reaching for it instead of coffee because the energy feels smooth and steady with no jitters or crash, and I like that it’s low caffeine and has no sugar. I also genuinely love the flavor and it makes me excited to keep drinking it and try more. Compared to other energy drinks I’ve tried, it feels more balanced and performance focused, and it helps me stay energized without feeling overstimulated

As a busy mom, I used to hit a major afternoon slump and struggled to power through everything that needed to get done. I’m so glad I discovered KEY Energy drinks! They’ve truly been a game changer for my daily routine. I love that KEY uses all-natural ingredients, and with only 80 mg of caffeine, I get the boost I need without the jitters or shaky feeling. My absolute favorite is the Pineapple Passion Fruit flavor. You can really taste the bright, fruity flavor in every sip. It’s light, refreshing, and not overly sweet like so many other energy drinks. I usually drink one around my 2pm slump, and it gives me the perfect pick me up just in time for when the kids get home from school and we’re rushing off to activities. The best part is that my energy lasts the rest of the day without any crash. I love that it's a clean, smooth energy boost without the harsh side effects.

Flavor is okay. Not sure what is causing a slightly bitter taste. It does have a similar effect to coffee for me in terms of alertness. Time will tell with other benefits.

I usually rely on coffee or energy drinks to get through long workdays, but KEY has honestly replaced both for me. The ketones give me a steady, clean energy boost without jitters or a crash later. I love drinking one before a workout or when I need to focus, I feel mentally sharper and more productive. It’s sugar-free and low caffeine, so it feels way smoother than typical energy drinks. The Pineapple Passionfruit flavor is refreshing and not overly sweet, which I love. Definitely recommend!!!!

The taste is very bad. My husband, who will eat or drink anything without complaint, refuses to drink them. My 43 yr old son says they are awful tasting. I can’t stomach it. Guess I’ll donate them to a food pantry

I’ve been a daily Celcius drinker for a long time, but I always struggled with the side effects of it. If I drank my Celsius too fast in the morning, my hands would start to shake as I’m working or typing notes and I would crash around 4pm that day. Since switching to KEY, I did notice a notable difference. The ketones gave me a smoother energy boost without being overwhelmed. Since I started drinking KEY instead of my other usual choices of caffeine, I feel way more focused and productive without the jitters and anxiety. I think the best thing about KEY is that the energy actually lasts and I can get through the day without crashing in the middle of class. So, I think the low caffeine and zero sugar actually does make it feel different from other energy drinks. I also love using KEY before workouts. It gives me enough energy to stay motivated and push through, but without feeling overstimulated like Monster and Celsius used to make me. As a college student who lowkey lives off energy drinks to get through the day, KEY is lowkey now my go-to option cause the jitters and anxiety were not it.
