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

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.

Pretty bad taste, but drinkable. Doesn't energize though, so save your money. I literally went to sleep after drinking one. Drinking one now, and I'm still dozing off.

My favorite pre gym drinks. I can’t have a lot of caffeine so this are wonderful and not full of stimulants. Love the pineapple the best!

My life in college is honestly kind of crazy between classes, work, and the gym. I used to depend on coffee, but it would either make me feel super jittery or I’d crash halfway through the day. I started using this and it’s been a huge difference. The energy just feels a lot smoother and more steady. I can actually focus and get things done without feeling anxious or all over the place. My anxiety is usually pretty bad during classes but since drinking this I have not had that problem. It’s helped me get through long days of classes and still have energy after for workouts or hanging out with friends. Now I use it in the morning or whenever I need to really lock in, and it just works. No crash, no weird feeling after. It honestly just makes my days feel a little more manageable.

I really wanted to like these, but I don’t think they’re worth the price. The ginger flavor was the best of the three, while the other flavors were harder to get used to. I finished the variety pack but don’t plan on buying them again. I also didn’t notice any improvement in my ketone levels while using them. They may work better for others, but based on my experience, I can’t justify the cost.

I’ve been burned by energy drinks before, the jittery crash, the sugar overload, the ingredient list that reads like a chemistry exam. KEY is genuinely different. It’s powered by ketones instead of sugar, and the energy it gives you is smoother and longer-lasting than anything I’ve tried. No spike, no crash, just steady focus for a few hours. I started with the Grapefruit Peach flavor and it’s refreshing without being overly sweet. The Pineapple Passionfruit is also great if you want something more tropical. The low caffeine (from green tea) means I can drink it in the afternoon without ruining my sleep, which is a huge win.

I was really excited to try these. I thought that they would be a wonderful all natural organic alternative energy drink. Unfortunately, they were very disappointing. They tasted very artificial. I also feel like there was misleading information on the website because when I actually got to see the ingredients on the can, it was citric acid Malik acid natural flavors and there was no actual pineapple or ginger or lime for the flavoring listed in the ingredients like there should be if it really is all natural. I had my family try them to see what they thought and they all agreed it was just very almost like it was overly sweetened with artificial flavors and too many artificial flavors and it was not good at all.

KEY has truly made a huge difference in my daily routine. I wanted a drink that would replace my coffee on my busy days and that’s exactly what it did. I love that it’s natural and made with Ketones, REAL ENERGY. I instantly feel a boost in my brain and body. What a GREAT feeling to feel more focused!
