The Truth About Nootropics: Efficient and Safe Brain Enhancers

Simply put, nootropics are natural or man-made (i.e. synthetic) compounds that are known to have positive effects on cognitive function, such as improving memory, attention, creativity, and motivation.

Nootropics may be frequently sought after by students looking to improve their studying habits or an office employee looking for that extra motivational boost to complete their daily duties.

Typically, nootropics can be divided into three primary categories: synthetic, natural (dietary), and prescription drug.

Because I like to deal with natural compounds that are freely available in the environment, this article is going to focus on a select few of the best natural nootropic compounds.


It’s no wonder that many people tend to organize their day around coffee breaks, after all, it contains caffeine, which is the most commonly consumed psychologically active substance in the world.

Caffeine is widely used due to its ability to increase energy and alertness, which it does by blocking the actions of proteins in the brain called adenosine receptors.

Typically, the average cup of coffee will contain about 95 mg of caffeine, and some people are known to achieve the benefits of caffeine with less, while others require more.

This all comes down to how you react to the dose of caffeine as some can be more sensitive to the effects of this compound than others.

Vitamin B6

Another compound that you will surely want to include in your regimen to boost cognition is vitamin B6.

Your body runs off oxygen—it is a necessary part of life and is in the air that we breathe in all around us.

Importantly, oxygen is also essential for cells to produce energy in the body.

If you think back to your younger years when you learned that “the mitochondria is the powerhouse of the cell”, you’ll begin to understand what we mean by the requirement of oxygen.

This is because mitochondria in the cell requires oxygen to make energy. But, importantly, mitochondria also require vitamin B6, too.

Vitamin B6 is also very important when it comes to your red blood cells.

As you may know, red blood cells carry oxygen from the lungs to all organs throughout the body. They do this by directly binding oxygen and shuttling it through your blood vessels.

However, without vitamin B6, molecules in the red blood cells cannot grab onto the oxygen coming from the lungs.

In this case, without vitamin B6, your body cannot use oxygen as much and you can begin to feel tired and unmotivated.


Next on our list is the compound called L-Theanine, which is an amino acid that can be found naturally in tea.

Researchers studying the effects of L-Theanine have found that it can have an overall calming effect and can increase attention and alertness.

L-Theanine may promote creativity and calmness by increasing alpha waves in the brain, as this specific type of brain wave has been linked to non-drowsy, relaxing states.

Gamma-Aminobutyric Acid (GABA)

GABA is a particularly interesting compound as it can not only be taken as a supplement, but it is also produced within your own body.

In fact, GABA is the main inhibitory neurotransmitter in the brain, which means that when it is released, it tends to reduce activity within the surrounding brain region(s).

Just as with caffeine, different doses of GABA supplements can have different effects, depending on the person. As such, if you are thinking of taking GABA supplements, you should also begin with a lower dose and work your way up.

In any case, studies have shown that GABA can greatly reduce stress and relieve symptoms of anxiety in some people.

And, people who were asked to drink a beverage containing only 50 mg of GABA were better able to complete problem-solving tasks and reported lower levels of tiredness while at work.


Similar to GABA, L-Tyrosine is also a naturally occurring amino acid that is produced by the body. It can also be found in a variety of foods like chicken, cheese, fish, and other foods high in protein content.

L-Tyrosine is an important amino acid because it is required to produce key neurotransmitters in the brain like dopamine and norepinephrine.

Dopamine and norepinephrine are important in the formation of memories while dopamine is also very important in maintaining wakefulness . In other words, dopamine is a neurotransmitter that is involved in keeping you awake and alert throughout the day.

Thus, including L-Tyrosine in your diet through food or supplementation is essential for staying alert and maintaining focus on challenging tasks in your day-to-day life.

Niacin (Vitamin B3)

Finally, we have another B vitamin that helps with cognitive functioning—vitamin B3, otherwise known as niacin.

Like other vitamins, niacin can be found in many different food sources like chicken, beef, salmon, peanuts, tuna, and lentils.

Niacin has been shown to have positive effects in animal models of Alzheimer’s Disease, and low levels of this vitamin have been linked to psychiatric disorder and brain fog.

Importantly, niacin is required for energy production and plays a key role in the development and survival of brain cells.

Without niacin, brain cells would struggle to produce the energy required to carry out daily tasks in our lives and would likely cause us great strain when dealing with stress.
