KEY Ketone Energy Drink : Sugar Free, 80mg Low Caffeine, All Natural, 11.5g Ketones, Long Lasting Energy, Green Tea & L-Theanine for Mental Focus, Variety Pack (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.

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 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!

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.

I’m always trying out new energy drinks, and this one caught my eye because of the ingredients. I prefer healthier options when it comes to caffeine, and the KEY Ketone Energy Drink checks all the boxes, having no sugar, low caffeine, and with natural ingredients.The ginger lime flavor is super refreshing and not too sweet. I’ve been drinking one before my gym sessions and it gives me a nice, steady boost without the crash. I also like that it has green tea, which helps me stay focused and feel more alert, without feeling jittery like other energy drinks usually make me feel.I’m really impressed and definitely plan to keep these stocked. They're easy to keep in my fridge and the perfect size for my gym bag too which I love! Great option if you're into clean energy and want something that actually makes you feel good.

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.
