PHOCUS Caffeinated Sparkling Water, Grapefruit, 75mg Natural Caffeine Plus L-Theanine, Zero Sugar, Zero Calories, No Artificial Sweeteners, 11.5 fl oz Cans (Pack of 12)

The "Phocus Energy Boost, Grapefruit" is a great product. It provides the necessary caffeine to keep you working through the afternoons without the need for sweeteners or sugar. It’s delicious and refreshing, with 75mg of caffeine from tea and added L-Theanine for a smooth energy boost. Highly recommended for a tasty, sugar-free pick-me-up!

My husband loves this stuff.

This product is AMAZING! I typically don’t like energy drinks because they upset my stomach and make me feel jittery. They’re also usually way too sweet and give me a headache. Once I heard about Phocus I decided to give it a try. I love soda water and was interested to see how this compared. It’s absolutely delicious and didn’t upset my stomach, give me a headache, or make me jittery. It’s the perfect amount of caffeine, and I would give this product 6 stars if I could!

It’s light and refreshing. I normally drink the Highball grapefruit sparking energy water but this is cheaper and not so heavy on your stomach because of the carbonation. Also , I really like the texture of the can. It grips in your hand just right.

Love these - they're super refreshing, especially when trying to kick coffee or other soft drinks. Plus, not at all bad for you!

I appreciate that it has not added sugars. It is basically sparkling green tea. I do wish there were no "natural flavors" I love the cola! I wish it were included in the "subscribe and save"

While doing Whole30 I wanted to find some energy drink that was not full of junk but able to provide some caffeine (since I am allergic to coffee) and Phocus was able to deliver that both of those things. I actually prefer this (the Grapefruit flavor is my favorite) to my old standbys (Cherry Coke Zero or Dr. Pepper). I was at an outdoor camp for a week and found myself ordering another case of these to bring with me. The price ($20/12=$1.67) is equivalent (or less) to buying a soda at a gas station. These have the added benefit of none of the junk.

Tastes exactly like the Highball grapefruit flavor with less caffeine. I prefer the Highball only because 75 mg of caffeine doesn’t help me feel very awake (12 ounces of coffee is usually more like 150-200 mg), but this is a good alternative for people who are really sensitive to caffeine. Very attractive labeling—way to go, design folks.
