Is it a Scam? Does It Really Work? Check Ingredients, Side Effects and More!

Nootrobox is a supplement company that offers mainly nootropics. Its headquarters is located in San Francisco, the USA. The company currently offers three nootropics - Sprint, Rise, and Yawn, as well as a chewable coffee gummy Go Cubes. The company was founded in 2014 by Michael Brandt and Stanford alumni Geoffrey Woo. Woo was an Entrepreneur, while Brandt was a freelance photographer and a Google employee. There is an official website that offers all of these products but it lacks important information about the ingredients and possible side effects of their nootropics.

Today we are going to focus on Nootrobox Sprint. It is one of the company's nootropic supplements which can be bought online at a price of about $35. The product claims to boost cognitive energy, mental clarity, and focus of the user. It promises to start working fast and stay effective for four to six hours after ingestion. But does Nootrobox Sprint really work? Let's try to answer this question by looking at its main ingredients.

Ingredients of Nootrobox - Does It Really Work? Is It a Scam?

Sprint is a daily nootropic that is meant to boost energy due to a caffeine-theanine combination. Other ingredients include vitamin B6, vinpocetine, vitamin B12, and L-tyrosine. These ingredients work in a similar way, however, Caffeine can be harmful for some categories of people despite its popularity in nootropics. Two Sprint capsules are equal to one cup of coffee.


L-theanine is commonly stacked with caffeine in a 2:1 ratio. It possesses anti-anxiety properties that help to decrease the negative effects of caffeine such as jitters and anxiety. Caffeine and L-theanine are said to boost cellular energy in the human body, as well as in your neural cells. Each capsule of Sprint contains 20mg of vinpocetine which is quite a lot. Vinpocetine is a derived from the periwinkle plant. It has an ability to cross the blood-brain barrier and is believed to improve reaction time, boost your attention and memory. But this compound needs more research and studies for proving its safety and effectiveness.

Another active ingredient in the product is L-tyrosine. It is an amino acid that is important for human brain function, as well as for the production of dopamine and norepinephrine. These are two neurotransmitters that play an important role in stress, cognition, and other functions of human physiology.

Vitamin B12 is a vitamin related to brain health, including brain mass and memory. There is a positive association between the intake of this vitamin and state of memory. However, overdose of Vitamin B12 can be dangerous for the human health. Vitamin B6 is another water-soluble vitamin that participates in the production of neurotransmitters. It can improve attention in children suffering from ADHD when used in conjunction with Magnesium.

L-Theanine is an amino acid that supports a calm mood without a sleepy effect. It can reduce error rates while doing different tasks when used in combination with caffeine. Glucuronolactone is a metabolite of glucose, which can be found in many energy drinks. But, there is too little research of the effects of this component. So, no one knows exactly what negative effects may occur.

Inositol possesses neurological properties. It is said to decrease anxiety and to regulate mood. Finally, Caffeine is a well-known stimulant that influences the central nervous system of a person. However, this physical performance enhancer may have negative effects on people with psychological conditions, high blood pressure and heart diseases.

Other ingredients of Sprint Nootrobox include vegetable hydroxypropyl, rice flour, methylcellulose capsule, calcium carbonate, and silicon dioxide. Sprint doesn't use unknown herbal extracts. At the same time, it contains well-known compounds which are not proven to supercharge your brain. The doses of some nootropic ingredients are unknown which makes them potentially risky for your health.

Customer Reviews - Does It Have Any Side Effects?

Most modern nootropic manufacturers do not conduct clinical trials. As for Nootrobox, this company has made a number of studies but they are very small, thus, they cannot reveal all aspects of this or that compound added to the product. The clinical trials involving Sprint are not complete. Obviously, the ingredients in this supplement need to go through the deeper scientific research and clinical testing. This cannot be done overnight, of course, and requires years.

The fact remains the same that many of its ingredients can potentially cause certain side effects. Major side effects include fast heartbeat, agitation, confusion, changes in the stools and urine, burning feeling in the stomach, bruising, chills, depression, fainting, dizziness, fever, headache, hostility, irritability, indigestion, lightheadedness, nausea, rapid and shallow breathing, rash, rapid weight gain, seizures, stomach pain, trouble breathing, stomach upset, unusual tiredness or weakness, vomiting. If any of these symptoms occur while taking Sprint Nootrobox, get help as soon as possible. Here are some of the testimonials left by true customers online.

"After trying Nootrobox several times, I couldn't tell much difference compared with a caffeine and l-theanine pairing. The only difference is the lower cost of the second option. Why pay more money for the same effect?"

"I didn't like sprint nootrobox at all. I got many side effects, probably because of the caffeine content. I felt rapid heartbeat, was too agitated and nervous. It does give some energy boost but it is not worth all the side effects you need to tolerate."

"This supplement didn't work for me. I have been using Nootrobox for almost a month, but I didn't feel any more focused or concentrated. The effect can be compared to a cup of coffee."

Where To Buy Nootrobox?

Nootrobox Sprint costs $35.10 for a package of 60 capsules on the official website. You can also subscribe to the subscription plan and receive the product each month; however, this program can be hard to cancel. You will not find it on Amazon, GNC or Walmart.

My Final Summary

There is nothing special about Sprint Nootrobox. It contains much the same ingredients as other nootropics. Is it another stack that gives a clean energy boost, that is very similar to ordinary caffeine-theanine pairing. It only contains B vitamins, but I don't think that vitamins are worth paying $35 for. The product is Caffeine heavy, so it should be avoided by people sensitive to this component. I cannot recommend Nootrobox to usage.
