Enhancing brain cognitive performance by utilizing nootropics has been a constant research topic for quite some time. Broadly speaking, nootropics belongs to a still unclassified group of research chemicals, a few prescription drugs and over-the-counter supplements.

The desired effect of these nootropics, when taken in combinations, are meant to improve the brain's ability to think, Futurism reported. It is not clear how nootropics actually work. There are many factors to consider, which includes the neurochemistry of the user.

The idea of taking nootropics is not simply taking a magic pill that can instantly transform one into a genius, as NZT does in the movie and TV series "Limitless" would have anyone believe, or that fictional synthetic drug called CPH4 in Luc Besson's "Lucy." NZT is compared to Modafinil or Provigil; drugs commonly prescribed to individuals with narcolepsy are considered by many as a "smart drug."

Nootropics work best when the right combination of substances is found (stacking), taken in the right amounts and proportions along with the proper time to take them. Accordingly, the core value would be optimization via incremental changes, sometimes small ones, expecting to produce a cumulative effect that is both powerful and progressive. Plainly said, results vary by a whole lot.

Some nootropic components are getting more research time than others are. Caffeine, for example, is known to affect the body. Coffee drinkers know that the effects and benefits of caffeine may be lost over time as the body builds up a tolerance to it, some even experience withdrawal-like symptoms when they don't ingest caffeine.

A new product called Qualia, claiming to contain 42-ingredients in two-step formulation that precisely calculates each ingredient dosage that illicit maximum potential along with other ingredients. It also claims that once taken, there would be an immediate and noticeable uplift of the user's subjective experience within 20 minutes.

One study found that brain function in elderly patients significantly improved when given regular doses of Piracetam. Likewise, another study stated that Piracetam increases memory in adults and help students improve their nonverbal learning skills. The thing is, researchers know that Piracetam works, unfortunately, they still do not understand why or how they work.

Nonetheless, the science behind nootropics is promising; however, it is still in its early stages. Proper combinations and knowing how they work still have to be figured out by scientists. However, many people are looking for ways to optimize brain performance; positive findings in nootropics are persuasive enough for them to consider giving nootropics a shot.
