Have you ever had a long, stressful day at work in which you found yourself struggling to focus on anything? You weren’t necessarily distracted, you were just drained or unable to be productive. Well what if you could take a pill that could not only make you focus, but increase your productivity tenfold, and even make you smarter. For anybody who has seen the film Limitless, this might sound a bit familiar, as this is the main plot of the movie. However, it seems as if this once far fetched, fictional idea has become a reality.

In the past few years, several people have claimed to have felt the mind-altering powers of nootropics, also known as “smart drugs.” According to a report from ABC News, hundreds of users on the popular social news website Reddit believe that nootropics actually increase brain functionality. In fact, the new supplement market is becoming so popular that sales exceeded a whopping $1 billion in 2015. And demand for the supplements is still growing.

One nootropics company that seems to have taken advantage of the smart drug trend is Nootrobox. Founded by Geoffrey Woo in 2014, Nootrobox manufactures and sells a variety of nootropics, each geared towards boosting different aspects of your body. Currently, the startup offers five separate types of supplements: YAWN, RISE, SPRINT, KADO-3 and GO Cubes. YAWN aims at optimizing your brain for sleep; RISE is a daily supplement, claiming to boost “memory, stamina and resilience”; SPRINT is essentially a large caffeine boost; KADO-3 implements important fish oils in order to protect the mind and body; and the GO Cubes can be quickly summed up as chewable coffee supplements.

As nootropics continue to grow, more companies like Nootrobox will continue to develop and push the boundaries of smart drugs.

However, not everybody is as excited about the nootropics craze. Because smart drugs are actually supplements, and not drugs, they are not regulated by the FDA. This has caused some major concerns amongst healthcare professionals. In the same ABC News article, Dr. Richard Isaacson expressed his issues with the lack of regulation and actual studies done on the benefits of nootropics.

Although Woo and his research team at Nootrobox are studying the effects of smart drugs, it is still a market that is far too young to call just yet. The long-term effects could still prove dangerous. Time will tell whether nootropics will become the future of dietary supplements, or if they will simply be forgotten.
