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)

This product stood out as it is all natural, highly rated, and very affective. It delivered a delicious taste while still providing energy and focus minus the after crash. This product not only tasted AMAZING but made me feel refreshed and energized. It was the perfect drink to grab before a long day especially as a college student. I love how there are no added colors, toxic chemicals, or weird ingredients. I have never had an energy drink made with ketones but I love it. It is great that it is not just about the caffeine but also sugar free, mental focus, long lasting energy, all natural, lowin caffeine, and overall amazing product!

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.

KEY Ketone Energy Drink is a refreshing, clean energy option that delivers smooth, sustained focus without the crash. With 11.5g of ketones, 80mg of caffeine from green tea, and calming L-Theanine, it provides a gentle but effective mental boost—perfect for work, workouts, or long days. The Ginger Lime flavor is crisp and natural, with no sugar or artificial aftertaste, and the all-natural ingredients make it ideal for keto, fasting, or anyone avoiding junky energy drinks. It’s become my go-to for clean, reliable energy, and I’ve already reordered.

Key Ginger Lime is an excellent choice if you want a clean, sugar free, balanced energy drink with moderate caffeine and supportive ketones.

I’ve tried a ton of energy drinks and was honestly skeptical about a “ketone-based” one, but the KEY Ketone Energy Drink blew me away. The Ginger Lime flavor is light, refreshing, and not overly sweet, which I really appreciate. There’s no weird aftertaste like some other sugar-free drinks.I love that it only has 80mg of caffeine—just enough to give me a mental boost without making me jittery. The green tea and L-theanine combo definitely helps me stay focused, and the energy lasts longer than I expected. No crash, no headaches, just a clean, steady pick-me-up.Also, huge bonus that it’s all-natural and sugar-free. I drink one before workouts or in the mid-afternoon when I need to power through emails.

It's perfect if you're wanting a workout later in the day and needing a small energy boost. The caffeine content is just right if you're looking for something effective but not intense.
