So what is a nootropic?
Nootropics are becoming more well known in western culture, however it was actually discovered and the term first came about in 1972, by a Romanian chemist Corneliu Giurgea  .
But it’s only recently that there has been more research and studies done. Manufacturers have started to use nootropics in their products and supplements and health practitioners have begun discussions over the use of many nootropics. Nootropic research may still be in its infancy, but it holds a lot of promise.
Nootropics can be a single supplement, or a few put together (known as a stack). Common examples are vitamins, minerals, amino acids, essential fatty acids, anti-inflammatory antioxidants and adaptogenic herbs. 
What are the different types?
There are natural nootropics and there are synthetic nootropics. Some people even categorise smart drugs or stimulants as nootropics.
Some examples of the most popular natural nootropics are panax ginseng, natural caffeine, lion’s mane, ashwagandha, rhodiola rosea, L-theanine, creatine and bacopa monnieri.
What is interesting, is many nootropic supplements have been popular for other reasons in the past, and now studies are proving they have amazing benefits for the brain, and they are being classed as nootropics. Many synthetic nootropics give a boost and a crash, whereas a lot of natural nootropics create a more gradual boost and do not have a sudden change in energy levels.
Two good examples are creatine, and ginseng.
Creatine is popular in the athletic and sports world as it can help build muscle mass, help with strength and bodybuilding. Yet there have also been findings to show that it works effectively as a nootropic to help with attention span, focus and alertness.
One of the most well-known nootropic supplements is Panax ginseng. For thousands of years, it has been used in traditional Chinese medicine to promote brain function and mental processing. 
How do they work?
Nootropics should allow the user more control over their neurochemistry and alter the brain chemicals to help those who find difficulty with focus and concentration.
They affect your brain by influencing the brain waves, cerebral blood flow, cellular energy, hormones, neurotransmitters, neuroplasticity or growth factors.
