Top 25 Nootropics for Your Health and Brain Function

Top 25 Nootropics for Your Health and Brain Function

Elliot L'Angelier Nov 7, 2018 1 comments

Nootropics (also called smart drugs or cognitive enhancers) are beneficial supplements that improve many of our brain and body functions. Whether you’re a student, athlete, or simply somebody who wants to improve their everyday life, nootropics might be the right substances for you. Learn which are the top nootropics below.

I used them mainly for increasing my mental performance regarding short and long-term memory, focus, awareness, and mood. They are also helpful for chronic fatigue, depression, anxiety, brain fog, etc.

Coffee is not something I use regularly, and I find the effects of nootropics are much stronger without a crash of energy at the end of the day.

Our brain uses hundreds of different chemicals and compounds to function properly. Some of them are produced in the body; others require a rich diet that most modern people have not adopted. It’s very difficult to get all the necessary vitamins and nutrients the body needs, especially if you are on a vegan diet. This is where nootropics come in to fill that hole.

In this article, I will list over 25 of my favorite supplements that I have tried and are the most popular among people who use them regularly. I strongly recommend trying some of the top nootropics mentioned here to see the effect they can have on your life.

Top 25 Nootropics

1. Korean Panax Ginseng

My rating: 5 of 6

Reviews on Amazon: over 500 positive customer reviews 

Ginkgo Biloba and Panax Ginseng

This plant has been used for thousands of years in traditional Chinese and Korean medicine. The modern research is still inconclusive, but it appears to have many biological and mental benefits. It has positive effects on long-term memory, a slight boost of energy, and some studies suggest it helps with menopause symptoms.

Since science is yet to understand this plant fully, I recommend combining it with another nootropic that is better known as the next one on my list.

Top Benefits

  • Enhances the immune system
  • Improves the health of the respiratory and cardiovascular systems
  • Energy Boost
  • Improves the appetite

Ginkgo Boloba Top Nootropics

Ginkgo biloba is one of the most popular brain functions inducing supplements and is widely cultivated around the world. We couldn't make a list of the top nootropics without including it. The tree is native to China and Japan and was used in traditional Chinese medicine since early ages. Many studies have confirmed it can enhance one’s memory and attention span.

It’s a great antioxidant; it can improve brain function, blood circulation, sight, and vision. It can reduce symptoms of anxiety, depression, and headaches; however, it should not be considered as a single treatment to these conditions.

The plant can reduce inflammation in conditions like cancer, heart disease, stroke, and arthritis. Some studies suggest it can be used to treat erectile dysfunction and boost your libido. It probably has to do with its blood circulation effects in the body.

Some of the side effects include increased risk of bleeding, nausea, vomiting, diarrhea, and dizziness. I recommend starting with a small dose (half a pill) and reading the instructions on the packaging. If you are pregnant or breastfeeding, seek advice from your doctor before taking Ginkgo Biloba. Some people may experience an allergic reaction to it.

Recommended initial dose: 400-600 mg
Usage: Daily 
My rating: 4 of 6
Reviews on Amazon: over 370 positive customer reviews

 N-A-C - Top Nootropics

NAC is the natural N-acetyl form of the amino acid L-Cysteine that can be found in our body. The basic amino acid methionine helps with the production of L-Cysteine in our bodies and can be obtained with certain foods. However, most modern diets, and especially vegan ones, lack this amino acid which is why supplements such as NAC are so vital. 

Stress or the presence of toxins in the environment can increase the need for cysteine. In such cases, the body is unable to synthesize the amounts needed naturally. The intake of NAC in the form of a nutritional supplement is preferable to that of L-cysteine because of its greater stability and absorption of N-acetyl-L-cysteine in the human body.

Vitamin D3 can be more than three times more effective if we maintain high levels of it in our blood for a long period.

It’s often used to increase our sex drive because its deficiency can cause low estrogen in women or low testosterone in men. Those hormones are also strongly correlated with our mood.

Usage: Daily 
My rating: 5 of 6
Reviews on Amazon: over 500 positive customer reviews

Magnesium L-Threonate - Top Nootropics

Magnesium is the fourth most common mineral in the human body. It is extremely important for the health of the cardiovascular system and is essential for fundamental functions such as energy production and storage of nucleotides for DNA and RNA synthesis.

Magnesium L-threonate increases the levels of magnesium in the brain because it passes the blood-brain barrier, which is extremely difficult for other forms of the mineral.

In clinical studies, the higher levels of magnesium ions (Mg2 +) in the brain due to magnesium L-threonine result in surprising effects. In the Hippocampus (responsible for long-term memory) it enhances memories and facilitates learning. In the amygdala (the part of the brain that controls our emotions) changes occur that make it easier to overcome fears associated with painful experiences and anxiety.

Top Benefits

  • Improves learning
  • Long-term memory

  • Decision-making
  • Brain food

Possible side effects

  • Gas

My rating: 4 of 6
Reviews on Amazon: over 10,000 positive customer reviews

Omega 3 Fish Oil - Top Nootropics on Amazon

I have included this supplement to my top nootropics list because of its favorable qualities for the body. Fish oil is known to help the functioning of cardiovascular, locomotor, nervous and immune systems and to maintain healthy cholesterol levels in the blood.

It’s very beneficial for dogs and cats as well, and I do give it to my pets since they can’t get it from their diet.

It is a rich source of Omega 3 unsaturated fatty acids. The most valuable of these are polyunsaturated fatty acids - EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).

Get it now. Vitamin C 1000mg

Vitamin C (also known as Ascorbic acid) is one of the most powerful and most important antioxidants. It helps the body in strengthening the immune system, preventing and treating colds and flu, wound healing and fractures, blood vessel augmentation, etc. 

Necessary for healthy teeth, gums, and bones. It is necessary for the synthesis of collagen. Vitamin C is known to prevent the conversion of nitrates (from smog, cigarette smoke, vegetables, bacon, etc.) into carcinogens (substances that cause cancer). 

My immune system has been much stronger ever since I started taking it daily. I was always the first to get the flu and I used to get sick at least two times each year. I’m happy to say that I haven’t been sick for over 2 years taking 1000mg of Vitamin C regularly. It goes into my personal top nootropics list. 

Top Benefits

  • Improves the function of the immune system
  • Helps with stress
  • Reduces fatigue
  • Powerful antioxidant
  • Improves vision
  • Improves Iron absorption
  • Slight memory enhancement

Possible side effects

  • Headaches
  • Vomiting
  • Stomach discomfort

However, I haven’t experienced any of those side effects and I do take a lot of it.

I will keep updating the information to this post and most certainly include at least 30 total nootropics that I think are very beneficial. I will soon make my comments on modafinil as well.
