Review of Nootrobox Sprint Nootropic
Nootrobox call Sprint their Nootropic designed to deliver a "flow state" full of focus without the jitters of sugary coffee or energy drinks.
Why Are We Telling You About Another Supplement Company's Nootropic?
Simple. We want you to be informed.
As part of our open-source initiative to turn the supplement industry upside-down, we're shining a spotlight on our own ingredients and formulations - as well as everyone else's.
What is Nootrobox Sprint?
Sprint is advertised as an "as needed nootropic to boost you into high gear." Nootrobox says their "ingredients were selected for their nootropics benefits, specifically their ability to put you in a 'flow state'. The sweet spot of feeling alert, cool, and in control."
So how are they delivering these benefits? Let's look at the ingredients in Sprint.
Nootrobox Sprint Ingredients
L-Theanine, Caffeine, Glucuronolactone, Inositol, and Vitamin B-6 are the ingredients in Sprint.
L-Theanine is a naturally occurring amino acid found primarily in black, green, and white teas, has been shown to reduce levels of stress and anxiety. Beyond relaxation, it has also been shown to increase mental alertness. [1-5]
Caffeine has been shown to act synergistically with L-Theanine to improve alertness and attention. The combination has also shown to create strong positive effects on word recognition and visual information processing. [1-5]
So far, so good...but here's where we think Sprint runs off course.
Glucuronolactone is a common ingredient in energy drinks due to claims it detoxifies the body and liver. However, little research has been conducted to aid this claim. Current research suggests it produces mild, if any, benefits to cognition or memory.
Inositol has been shown to reduce anxiety and regulate moods. However, these results are relatively mild and tied to much higher dosages than the 185 mg found in SPRINT. Normally around 6 grams is needed, a whopping 30x what is found in Nootrobox SPRINT.
So Nootrobox's Sprint only provides 1/30 of the effective dose of this ingredient (if it even turns out to be effective).
Your Solution for Increased Mental Alertness and Energy Without the Jitters
Nootrobox SPRINT seems to be an unnecessary take on an already solid L-theanine + Caffeine stimulant combination. SPRINT has added ingredients to this strong supplement base, however these additives, Glucuronolactone and Inositol, have yet to show any kind of tangible effect on their claims of detoxification and mood regulation.
While these additions are commendable, their lack of proven positive effects may prove to weigh down and lessen the overall effect of the Sprint product.
That's why we stuck with the basic, science-backed combination of L-Theanine + Caffeine to create our best-selling Smart Caffeine formula.
This combination has been shown to:
- Improve both speed and accuracy of performance in intense, attention-switching tasks 
- Reduce susceptibility to distracting information during tasks of memorization 
- Produce faster simple reaction time and faster numeric working memory reaction time 
- Increase feelings of 'alertness' with the L-theanine/Caffeine combination rating higher than Caffeine alone 
- Significantly increase concentration when performing intensive tasks
