Before using any cognitive enhancer, it is important to have a brief introduction of it. Cognitive enhancers are the type of supplements that are used to improve our cognitive functions like memory and concentration. They are also used to enhance focus, motivation, and clarity of mind. These drugs known as brain supplements, smart drugs or nootropics. The word Nootropic actually means brain and bend in Greek. This means Nootropics can turn your mind towards the improvement. Using Nootropics can also make you learn things quickly.

Students and entrepreneurs consider Nootropics the most effective drugs. If you want to improve your mental powers as well, you must start using Nootropics. Cognitive enhancers also increase your productivity, alertness and creative ability.

It is important to tell you that you can find the same qualities as smart drugs in natural herbs as well. Natural herbs just like mushroom and other vegetables can also work like smart drugs. A smart drug includes vitamins and amino acids in it which make it super-efficient for the brain. The smart drugs can be described by two categories. Below mentioned the best cognitive enhancers are all you need to improve your brain powers.


Lion's Mane

Bone structureLion’s Mane is an ancient medicinal mushroom that protects nerve cells and enhances cognitive function. This medicine was popular among ancient physicians to treat degenerative diseases because it can restore brain function by activating the growth of damaged nerves. Regular intake of this drug increases the amount of Nerve Growth Factor (NGF). Nerve Growth Factor is very important for the survival and proper functioning of nerve cells. It enhances cognition by promoting neural growth. Research has proven that this drug also stimulates nerve myelination and helps to decrease anxiety and depression symptoms in just four weeks. It is also best for nootropic stacking. In summary, the benefits of this amazing drug are:

  • It increases memory
  • Helps deal with anxiety and depression
  • Improves cognitive functions
  • Stimulates myelination
  • Increases NGF and promotes nerve growth

Bacopa Monnieri

Brain nervesMade from the herb name bacopa monnieri, this supplement is used traditionally in medicines like Ayurveda and is very beneficial for the improvement of brain function. Researchers have shown that it is useful for improving memory and thinking skills both in healthy people and those people who are suffering from any decline in brain function. One thing to note is that only repeated use of this medicine improves brain function. 300 mg of Bacopa Monnieri is taken daily, andit shows its result in about four to six weeks.

Studies have also shown that it may sometimes cause upset stomach and diarrhea. To avoid this, it is better to take this brain nootropic with food.

Rhodiola Rosea

FatigueWhile many drugs work to increase cognitive abilities, Rhodiola Rosea is unique in the sense that it helps to preserve cognitive function along with boosting cognitive abilities. Rhodiola Rosea is herb found in the mountainous regions of Asia and Europe and has been used in traditional Chinese, Russian, and Scandinavian medicine as a cure for the restoration of cognitive abilities and fatigue for thousands of years. Research has shown that this drug reduces various fatigue symptoms like headaches, muscle soreness, and sleepiness. It also increases productivity and mental work capacity in individuals. It enhances many cognitive functions such as short-term memory, calculations, concentration and helps overcome overall mental fatigue. It improves test-taking ability in students.  A study done on students has shown that students who took Rhodiola scored 8.4% higher in their exams than those who did not. Rhodiola is a complete nootropics drug and can be taken individually or as a nootropic stack.

Amino Acid Cognitive Enhancers

Fish Oils

omega-3 fish oilsFish Oil supplements are a great source ofproviding two types of omega-3 fatty acids; eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These two fatty acids are very beneficial for health including improvement of the brain health.

Docosahexaenoic acid (DHA) plays a very important role in maintaining the function and structure of the human brain. It consists of 25% of total fat in your brain and 90% of omega-3 fat which is found in the brain cells. Eicosapentaenoic acid (EPA) is the other fatty acid found in fish oil that has anti-inflammatory effects that keep the brain safe from aging and damage.

Docosahexaenoic acid (DHA) supplements have helped to improve the reaction time, memory and thinking skills in healthy people that have very low DHA intake. The people who have experienced a mild decline in their brain function have also been benefitted from DHA. EPA doesn’t always affect brain function like DHA. It benefitted the people who have depression by improving their moods.

Intake of fish oil containing both fats DHA and EPA helps to reduce the decline in the brain function that is due to the aging factor. However, the proof of the effects of fish oil’s preservatives on the human brain is mixed.

The recommended intake amount is 2 portions of oily fish weekly, butif it is difficult to manage,then you can take fish oil’s supplements. For finding the exact ratios of EPA and DHA, more studies are needed, butfor now, 1 gram combined intake of both the omega-3 acids is recommended and is beneficial for brain health and maintenance.


Nerve cellIt is a naturally produced amino acid in your body that plays a vital role in maintaining your metabolism and specifically in the production of energy. It has been claimed that intake of acetyl-l-carnitine improves your memory, makes you feel more alert, and slows down memory-loss caused by growing age.

Some of the acetyl-l-carnitine animal studies have shown that it increases learning capacity and prevents decline that is related to age. Acetyl-l-carnitine human studies have shown that it is a very beneficial supplement for preventing the brain function’s decline due to age. It is also quite useful for improving brain function in people that are suffering from Alzheimer and mild dementia.

However, there isn’t any research or study to show its beneficial effects on people who are healthy and not suffering from any loss of brain function.


RelaxationAn amino acid present in green tea leaves L-Theanine has been known to reduce stress and promote relaxation. It reduces heart rate variability. It enhances mental alertness by increasing alpha brain waves. It is a wonderful nootropics stack. When you combine it with caffeine, it has been known to produce some very intriguing properties such as the increase in memory, endurance, and reaction time. When you take L-Theanine with caffeine, it also helps to mitigate different adverse effects of caffeine such as increased blood pressure and jitteriness. L-Theanine helps:

  • Increase learning ability
  • Enhance reaction time
  • Increase concentration and mental alertness
  • Helps in stress reduction and relaxation
  • Decreases the negative effects of caffeine


You now have an idea of natural and amino acid nootropics, which will give you a better understanding and the ability to make a smart choice. Although we did try to choose the best cognitive supplements, they may result in some side effects. It is highly recommended to take your doctor’s advice beforeusing any smart drug. Different smart drugs work differently on human body and mind. You must use the best cognitive enhancers as per your needs and preference.
