Go Cubes Review – Will Caffeine Gum Replace Your Regular Coffee?

This is our review of Go Cubes®, a caffeinated gum-like nootropic food which takes the form of concentrated coffee along with other ingredients contained within a cube of pectin.

First, we take a look at the nature of the product itself, then we discuss the effects present when taking it. We also cover a bit on Nootrobox, the maker of Go Cubes.


There’s no doubt about it. Coffee is the trusty, go-to stimulating beverage for millions, if not billions of people in the world.

With the fast, demanding world we live in, people rely on the caffeine and micronutrients (such as MAOIs) of coffee to stave off fatigue and depression.

While we love our coffee so dearly, there are a few drawbacks associated with it, such as cost, volume, and jitteriness.

In response, a company by the name of Nootrobox has swooped in the tackle these issues with their own product – Go Cubes.

What are GO CUBES?

Imagine, if you will, taking a cup of black coffee and removing all of the water, leaving only the concentrated solids behind.

Then, take what’s left and suspend it in a tiny cube made of pectin, which is a gelatinous substance derived from certain fruits (such as apples).

Finally, cover the cube in a bit of sugar for taste, and you have this:

Now I assure you that despite their gumdrop-like appearance, Go Cubes are NOT to be treated like candy.

There are some serious ingredients behind them, which give you an upgraded version of the stimulation you’d get from coffee.


Before we go into what it’s like to try GO Cubes, let’s just check out what Nootrobox has put into the formula. Copied from their website, here are the nutrition facts:

what ingredients are listed in gocubes gum

Notice, right away, that it’s “Nutrition Facts”, not “Supplement Facts”. The Go Cubes product is treated here as more of a food product than a straight-up nootropic.

This implies that the product is quite safe for human consumption (even according to the FDA).

In terms of active nootropic ingredients, there is a simple list.

Most prominently, we have caffeine, which shouldn’t have to be explained too much. It’s the most common stimulant drug in the world, which mainly works by blocking the activation of adenosine receptors (which allow us to feel fatigue).

Benefits include enhanced focus, strength, and being less prone to errors when tired. By itself, it can make a person feel hyperstimulated and jittery in high enough doses. However, this can be mitigated when combined with…

Theanine, which is an amino acid found naturally in many kinds of green and white teas. It relaxes the mind, helping it approach a mild “zen” state with the noticeable increase of alpha brainwaves.

The combination of theanine and caffeine is the basis of many modern nootropic stacks, and is why green tea is both calming and focus-enhancing.

Inositol is a sugar alcohol that contributes a bit to the sweetness of Go Cubes, but it also has antidepressant properties according to one
