Amazing
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.

100% Natural Energy
Key is a good tasting energy drink that has a great flavor variety. I lile the fact that it is a pure drink with 100% natural ingredients. Ulike other drinks, there was sustained energy without the crash, however there was a noticeable taste of stevia that took away from taste in my opinion.

Awful.
I was actually excited for these, but the flavors were bad. I tried all three flavors, but had to dump the can halfway and I don’t like wasting. The ginger lime was the most palatable. The pineapple passionfruit was the worst and trying to drink it w/o tasting it was bad- like the orange antibiotic syrup you took as a child. The grapefruit peach was akin to sugar free chalky candy. I feel like the stevia killed it and they would’ve tasted better w/o any sugar alternative at all. I liked that it had natural ingredients, but was expecting more of a seltzer. It’s a bit pricey for a 12 pack as well, but I got it as part of a rebate. Thankfully I was able to give it to someone who at least thought it was ok.

Great flavor and energy boost
KEY does not disappoint – it has great flavor (my favorite is Pineapple Passionfruit) and does not make me jittery. The packaging is beautiful and because the cans are thin, they’re easy to transport. They taste better than other energy drinks and the calorie count is great. I’ve been drinking them cold and storing in the fridge, but they taste good at room temperature too.

Tastes like vomit
I didn’t look at the flavor when I ordered and now I can’t stop thinking about what a terrible combination grapefruit, peach and bitter stevia is as it has the acrid sour taste of stomach acid. I’m drinking them because I purchased them, however, but I’m not getting the same feeling I’ve gotten in the past with other ketone drinks.

Low caffeine but more energy than “normal” energy drinks
This is definitely an acquired taste due to the ketones but after my first can, I got used to it and looked forward to having one in the afternoon. Ive tried the usual canned energy drinks with way more caffeine and they rarely ever help give me any energy. This has way less and I actually feel awake and can focus, im guessing its the ketone caffeine combo. Its pricey but im keeping some in my fridge for those days where I dont have time for an afternoon nap. I recommend the Variety Pack to find the flavor you like since they arent the most common flavors.

Good Energy Horrible Taste
Energy provided was good with no crash. The flavor was if well vodka and expired grapefruit with a hint of chemical. Somewhat disappointing for the price.

So much better than coffee! a must try
I recently tried the key natural energy drink, and I’m genuinely impressed! The taste is refreshing and pleasant, with a hint of natural fruitiness that doesn’t feel overly sweet or artificial. What stands out the most is how it provides a clean, natural, sustained boost of energy without any jitters or crashes. It’s clear that key focuses on quality ingredients and a balanced formula. For anyone seeking a natural alternative to traditional energy drinks, this one is definitely worth a try.
