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. ### ⭐ Expensive and doesn't work. *by on Reviewed in the United States April 17, 2026* 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. ### ⭐⭐⭐⭐⭐ College Life Saver *by on Reviewed in the United States April 5, 2026* 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. ## Frequently Bought Together - 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) - Drink Update No Sugar, Caffeine-Free Energy - Jitter and Crash Free, No Overstimulation, Healthy, Natural, Improved Focus, No Sucralose, No Artificial Flavors Made with Paraxanthine (Variety, 12 Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/635168414-ketone-energy-drink-sugar-free-and-all-natural-from-ketones](https://www.desertcart.us/products/635168414-ketone-energy-drink-sugar-free-and-all-natural-from-ketones) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-11*
