Are you looking to improve memory, and enhance cognitive performance and brain health? 

In a world as competitive as today, we are always on the go as professionals climbing the career ladder or aging adults concerned about their cognitive function. 

With how far science has come, it’s no surprise that there are smart drugs that can help us boost focus and mental performance. 

There is a large variety of nootropics on the market, making it a struggle to choose between one or the other. 

This article on the best Nootropics for focus and concentration will cover the best smart drugs that can help you enhance brain function and improve memory.

But are they safe? What are the side effects? Read along as we break it all down for you.

What are Nootropic supplements?

A nootropic drug is a natural or synthetic substance that is manufactured to improve brain function. 

Nootropic drugs can be used as cognitive enhancers or as a natural stimulant which may improve your mental performance and enhance focus. 

These drugs can be categorized into three types: 

• Dietary supplements 
• Prescription drugs
• Synthetic compounds

Healthcare professionals have different opinions on the use of nootropic supplements. 

Some argue that any mental benefits of nootropics are a result of the placebo effect – if you think your mental focus has improved and feel more confident, then you are bound to be better at the task at hand. 

Others believe that nootropic supplements indeed improve cognitive functions and boost mental alertness to some extent. 

How Do Nootropics Work?

Research is still being conducted to find out exactly how different nootropics work however, studies suggest some nootropics can increase cerebral blood flow allowing the brain to make use of more oxygen.

Nootropics influence different neurotransmitter systems such as glutamatergic and cholinergic systems; they also affect brain bioenergetics – increasing the production of ATP.  

While others affect the levels of neurotransmitters present in the body such as dopamine or serotonin as well as brain waves, and growth factors. 

These factors influence your mental abilities and performance. Nootropics work to optimize all these factors to improve cognitive function. 

There are two kinds of nootropics: Water-Soluble and Fat-Soluble. Water-soluble nootropics such as L-theanine dissolve in water easily and taking them with water ensures your body absorbs them efficiently. 

On the other hand, Fat-Soluble vitamins like Vitamin D require dietary fats to work optimally.
