KEY Ketone Clean Energy Drink for Focus, Zero Sugar, Low Caffeine, Natural | Pineapple Passionfruit 12-Pack, 80mg Green Tea with L-Theanine, Healthy Energy No Crash or Jitters, No Sucralose or Aspartame

I love KEY it gives me a clean, sustained energy boost thanks to the 11.5 g of ketones. I’ve started using it in place of my morning coffee, and I feel focused and steady at work instead of jittery. Other days, I’ll grab a can before a workout, and it helps me push through without feeling wired. Because KEY has only 80 mg of caffeine (from green tea), I never get the typical crash or anxious spike. And with zero sugar, thankfully there’s no sugar crash either. Having tried other energy drinks, KEY feels totally different. It’s still strong, but my energy feels better because of the ketones. I highly recommend it for anyone who wants smooth, lasting energy without the highs and lows.

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.

I rarely write reviews. My boyfriend and I have had Key for the last week or so, and I'm kinda blown away. What did it for me was when I was working last Saturday. After a shift in 90+ degree heat + humidity, I had a can of Key around 4pm because it was my friend's last night in town and a group of us were all going out; I wanted to be there for her and didn't want to be yawning all night. I was dancing until 3am and had so much fun. No yawns, no crashes, no stomachaches, no jitters. Literally just the energy to have a fun night with my friends. AND I had no issue sleeping that night (probably because of the L-theanine which promotes relaxation!). I also love that Key is vegan, and the ingredient list is short, clean and all-natural. I usually drink Key straight out of the fridge, it tastes much better cold than at room temperature (ketones don't have the best taste, but they did a great job at covering it up). Ginger Lime is my favourite, Pineapple Passionfruit is a close second. My boyfriend likes pineapple passionfruit the best. Vodka Redbulls are gross (IMO) but would totally mix the ginger lime flavour with vodka for a makeshift Moscow mule. I'm generally pretty health-conscious and love nutritional science. Coffee makes me insanely jittery (even just half a cup) and Celcius makes my stomach hurt (probably from artificial ingredients, couldn't finish a whole can). I would never have either of those on an empty stomach as well, but usually have Key on an empty stomach, I also feel its effects a bit more when I do. I used to consistently have matcha + raw cacao in the mornings for the L-theanine + low-caffeine combo to put me in a focused, flow state for the day; particularly useful for studying/working. Because Key also has L-theanine and caffeine (both derived from green tea), it gives me a similar effect to get work done, but also gives me longer-lasting energy from the ketones (which also gives me a bit of a euphoric/happy feeling?? My boyfriend reported also being in a great mood after drinking a whole can too. A quick Google search has shown me that this is commonly reported with people in ketosis/on the keto diet as well.) Now, I alternate between my DIY drink and Key depending on whether I need sustained energy that day or not. If you're a nerd like me, check out these two papers about L-theanine + caffeine to see how this combination can enhance focus and attention (and it's even been suggested as an Adderall alternative too): [1] The Cognitive-Enhancing Outcomes of Caffeine and L-theanine: A Systematic Review (2021) [2] Effects of L-theanine-caffeine combination on sustained attention and inhibitory control among children with ADHD: a proof-of-concept neuroimaging RCT (2020) Finally, I also like how I am supporting mitochondria uncoupling with ketones (read Dr. Gundry for more) and love that the benefits of ketone drinks that used to only be available to support athletes and members of the military are now available for everyone to reap. Cannot recommend Key enough, I'll rave about it to whoever will listen.

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.

This drink is absolutely delicious and so full of healthy benefits. I used to drink sugary energy drinks that would give me a boost of energy and then I would crash from the high sugar levels. This drink is so hydrating, sugar-free and a great pick-me up to keep me going during the day after a long morning of classes. I also drink Key before my soccer games to avoid getting jitters and maintain focus, which it is geared towards. Overall amazing drink to integrate into my everyday life!
