Chewable Coffee

GO CUBES are the future of coffee. GO CUBES combine the kick of coffee with the relaxation of green tea. And instead of putting your coffee in a cup, you can put it in your pocket, for performance on the go.

GO CUBES pack half a cup of coffee (50 mg caffeine) into a single cube. But it's more than just coffee. Through Nootrobox's R&D, we've reduced the jitteriness of caffeine and added nootropics for a well-rounded, steady and focused feel.

2 cubes = 1 cup image

GO CUBES come in convenient 4-packs. Since each CUBE is equal to half a cup of coffee, a 4-pack is equal to 2 cups. GO CUBES are sold as either a sampler of 6 x 4-packs or as a full box of 20 x 4-packs.


One serving is two GO CUBES, which is about the same caffeine content as 1 cup of coffee (100 mg). Gauge your GO CUBES intake off of how much coffee you typically drink.

A serving of two GO CUBES is effective for 4-6 hours.

Coffee Reinvented


How much caffeine is in your regular cup of joe? 25 mg? 200 mg? You have no idea. It depends on many variables, including, bean varietal, process, and barista skill. Know exactly how much caffeine you consume so you can stay perfectly in the zone.


In addition to caffeine, GO CUBES contain precise amounts of other safe, effective supplements like L-theanine, B6, and methylated B12 that improve caffeine for enhanced focus & clarity.

We made coffee you can put in your pocket. GO CUBES are perfect for your purse, backpack, or briefcase. They're the easiest way to always have coffee on hand with no mess & no stress.

Scientifically Delicious

GO CUBES are made with cold-brew coffee and premium ingredients to craft a unique taste, texture, and experience. GO CUBES are made with a pectin base, for a gummy with perfect texture and mouthfeel. GO CUBES are available in 3 flavors: latte, mocha, and pure drip, as well as assorted packs.


Pure Drip


Nootropic Ingredients

The components in GO CUBES are selected for their immediate cognitive effects, specifically for their effects on alertness, focus, memory, and reaction time. The amount, concentration, and ratio of each ingredient are specifically drawn from double-blind, peer-reviewed journal studies that statistically significantly demonstrate each compound's efficacy.

These ingredient amounts are reflective of a serving size of two GO CUBES.

Caffeine and L-Theanine

Research shows that L-theanine + Caffeine together have strong positive effects on word recognition, rapid visual information processing, attention, and mood beyond the effects of Caffeine alone. These cognitive benefits carry over into a wide variety of cognitively demanding tasks we face in our jobs, classes, etc. While Caffeine and L-theanine are found naturally in tea in a 2:1 ratio, the specific ratio of 1:2 in GO CUBES matches the dosage widely shown in clinical trials to produce optimal performance gains.

Vitamin B6

Vitamin B6 has been shown to aid cognitive function and improve metabolism in general. GO CUBES contain 2 mg of B6, which is 100% of the FDA's recommended daily value.

Vitamin B12

Vitamin B12 has been shown to have beneficial effects on cognitive function as well as general health of neurons.


Glucuronolactone binds with toxic substances in the bloodstream, and converts them into water-soluble conjugates that can be excreted in urine. These toxic substances are especially likely to build up under stress, lack of sleep, etc.


Research suggests that Inositol has has positive acute effects on lowering anxiety, increasing mood, and improving memory.

Why did you use sugar? Are there lower calorie versions?

A serving of two GO CUBES contains sugar that helps cut into the natural bitterness of coffee and caffeine, producing a product that balances performance and taste.
