Review: ⭐️⭐️⭐️⭐️⭐️ My New Everyday Energy Drink - I’ve been trying to cut back on caffeine and KEY has honestly become the perfect replacement for me. I used to rely on coffee every day for energy, but this feels like a much better and healthier option. The energy is clean and steady without the jitters or crash that I sometimes get from coffee. One thing I really love is how fresh the drinks taste. The flavors are unique compared to other energy drink brands and don’t have that overly artificial taste. My personal favorite is the Pineapple Passionfruit, it’s refreshing, slightly tropical, not too sweet, and super easy to drink. This has become part of my daily routine. I’ll drink one when I’m working late nights and need to stay focused or before a workout for an extra boost of energy. Super recommended!!
Review: The best new healthy energy drink! - This drink is absolutely delicious and so full of healthy benefits. I used to drink sugary energy drinks that would give me a boost of energy and then I would crash from the high sugar levels. This drink is so hydrating, sugar-free and a great pick-me up to keep me going during the day after a long morning of classes. I also drink Key before my soccer games to avoid getting jitters and maintain focus, which it is geared towards. Overall amazing drink to integrate into my everyday life!

### ⭐⭐⭐⭐⭐ Amazing
*by K***E on 13 July 2024*

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.
