Sweet, portable, convenient, affordable, and better than a cup of coffee. These are a few claims made by Nootrobox about Go Cubes. Go Cubes are chewable gummy squares made from cold brew coffee, designed for an on-the-go energy boost when you don’t have time to sit down and sip. Each cube contains 50 mg of caffeine, which is equivalent to about half a cup of coffee. Sounds like a dream come true for busy caffeine addicts, right?

Go Cubes aren’t just coffee, though. They also contain nootropics (supplements that boost cognition) such as L-theanine, vitamins B3, B6, and B12, glucuronolactone, inositol, and folic acid. You can read more about this here. Most of these supplements have been proven to enhance cognitive function, although one review points out that inositol is only effective in much higher doses than Go Cubes contain. L-theanine in particular is a green tea extract that serves to counteract the jitters that some people experience when they have caffeine.

Reviews so far have been mixed. While everyone seems to agree that Go Cubes are convenient and effective, there have been some complaints about the taste. One reviewer said that it was “sweet… but after a couple of chews the taste instantly turned bitter.” Another likened the aftertaste to “drinking nothing but coffee for a week while not brushing your teeth.” Out of the three flavours – pure drip, mocha, and latte – the lighter latte flavour seems to be most popular. However, reviewers have pointed out that it’s very difficult to tell the flavours apart, as there’s a mix in each package of four and they’re all varying shades of dark brown. Others complained of upset stomachs and bad coffee breath.

Odd taste aside, most reviewers agreed that the cubes simplified their morning and pre-workout routines, helped them keep track of their caffeine intake, and were overall cheaper than buying coffee throughout the day. Are Go Cubes the future of coffee? Maybe not, but they’re certainly another fresh, innovative way to get your fix.
