KEY Ketone Energy Drink - Sugar Free, 80mg Low Caffeine, All Natural, 11.5g Ketones, Long Lasting Energy, Green Tea & L-Theanine for Mental Focus, Pineapple Passionfruit (Pack of 12)

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.

From the very first sip, I noticed how clean and balanced the flavor was. The Grapefruit Peach flavor came through as a refreshing blend with just the slightest tartness that enhanced the taste rather than overpowering it. Unlike many other energy drinks, there was no unnecessary extra sweetness masking the flavor. It’s sugar-free and made with all-natural ingredients, which makes it a healthier choice and something I feel good about drinking.The texture was smooth and light, making it easy to drink, and it left no unpleasant aftertaste. It was so good that it made me want to keep sipping. About 15 minutes after starting, I began to feel the energy boost kick in, steady and gradual, never overwhelming. Instead of a sudden jolt, it gave me a clear, focused energy that felt natural, almost like I had just woken up from a great night’s sleep.I experienced no jitters or crashes, which is rare for energy drinks, and I stayed productive and alert throughout my tasks. This is easily one of my top favorites now, not only for its smooth, balanced taste but for the calm yet effective focus it provided. I would buy this again!

I really like how this is a healthier energy drink compared to a lot of other energy drinks out there. The ingredients are clean and it has less caffeine which I like. The grapefruit flavor was little strong for my liking, but the texture of the drink was good as it was smooth and not too carbonated. This is a good drink choice if you're looking for a healthier pick me up.

Just tried KEY Energy Drink and it’s a solid option for a more natural and healthier energy drink compared to traditional energy drinks. I like that the caffeine is sourced from ketones and each can provides 80 mg. It's effective enough to give me the boost I need, without the crash I get from other energy drinks that are loaded with sugars.The pineapple passionfruit flavor is good, although on the sweeter side. You can definitely taste the stevia in these, so be mindful if you're sensitive to that flavor.Overall, it's a good option for a lighter and healthier energy boost.

This energy drink stands out with its clean ingredients and no sugar, which I really appreciate. The taste is more natural and ‘earthy’ than some of the sweeter options out there, but that makes it feel less artificial. I also like that the caffeine is lower, so it gives me energy without making me feel super jittery.

I recently purchased the Key Grapefruit Peach energy drink and was pleasantly surprised by how much I enjoyed it. The flavor and texture profile were intriguing, smooth and refreshing with a perfect balance of tart and sweet. It was light, crisp, and not overly sugary, which I really appreciated.The design of the can was eye-catching, and the tab at the top was easy to open. The drink gave me just the right amount of energy to stay focused without the jitters, and best of all, there was no “crash and burn” feeling once it wore off, unlike most energy drinks. It felt like a natural pick-me-up rather than something heavy or artificial.If you’re looking for an energy drink that actually tastes good, provides the right boost, and keeps you feeling sharp throughout the day, I would definitely recommend giving this one a try!

Tried to like it, but the taste is not for me
