Amino acids are essential in life and affect all areas of your body. Some amino acids are essential to brain health while others take a back seat in the process. Your body is able to produce a portion of them while the others need to be included in your diet. This list works to guide you in the right direction for proper supplementation and optimal nootropic effect, with a focus on brain boosting powers. Whether you’re looking to enhance your mood, increase focus or calm your mind these natural enhancers that are key to survival will help you fill in the blanks.

Nootropic Amino  – Tyrosine


Tyrosine is a non-essential amino acid working as a pre cursor for your thyroid gland. It can be produced by your body from phenylalanine and is also found in certain foods. It can also be supplemented into your diet if there are signs of depletion or during times of stress where supply may run low. Tyrosine has been specifically studied for its ability to react during times of stress and sleep deprivation. When your body has plenty of available tyrosine metal stressors and even physical stressors (like the one here done in cold temperatures) are handled easier.

This amino acid although classified as non-essential is however an essential component for the production of the brain chemicals we call neurotransmitters. Some of these include adrenaline along with the stress associated ‘norepinephrine‘, known for its fight or flight sensation given when released.

How to choose the right tyrosine supplement?

Here is a guide to help you pick the right tyrosine supplement for your individual needs:

  • Choose one that was formed through a bioactive process to make it easier for your body to absorb.
  • Try to find ones that are given above 500gm per serving for optimal dosage and convenience.
  • Deficiencies can be common if you suspect that your body is low in an amino acid like tyrosine. If this is the suspected case choose ones that already contain copper and iodine for proper synthesis of the supplement.
  • Generally the saying is true “you get what you pay for” especially when looking for supplements. Since tyrosine is typically extracted from corn opt in for a non GMO source, it’s worth the few dollars more. AOR makes a great formula which is often recommended by naturopathic doctors.

Tyrosine is a great nootropic option for someone looking too boost their mood and cognitive performance. It can be especially helpful for people planning on having periods lacking in sleep as supplementing with this amino acid has already shown improvements in the ability to handle the mental stress of sleep deprivation.


Nootropic Amino  -L-theanine

Perfect for the days where caffeine agitation is becoming more troublesome then motivating L-theanine work to calm a tense mind without inducing drowsiness. L-theanine is one of the main active ingredients in green tea leading to the calm and clarity normally associated with drinking tea, far separate from the caffeine buzz one gets after a cup of coffee.

L-theanine is an excellent addition to a nootropic stack whereby two compounds are combined to create a more desirable effect.  Using this amino acid as a supplements allows for specific doses to be taken in conjunction with caffeine pills, allowing for the energetic motivation that comes from high amounts of caffeine without the restless jitters normally associated.

Choosing the right L-theanine supplement

  • Green tea is a great source for someone just starting out, a few cups in to an organic variety and you will sense the difference immediately.
  • For people looking for an easier to take more reliable dosage consider choosing a range between 200mg and 300mg per serving for the best results.
  • There are cheaper synthetic forms of theanine, but be sure to get L-theanine, the “L” signifies that it is derived from natural sources in this case from green tea.

L-theanine has been an important part in adding mental clarity to the lives of monks and academics alike and should not be overlooked from its innocent source. Adding this amino acid into your nutritional diet will give you a calming clarity perfect for life’s mental roadblocks.


Nootropic Amino  -Glutamine

Probably one of the most widely supplemented amino acids among bodybuilders and those looking to improve their physical state Glutamine or L-Glutamine. In this case it is commonly used for muscle rejuvenation after peak physical performance as a means of recovery.

Unlike the other amino acids above, Glutamine is an essential amino acid your body needs to source during specific situations of physical trauma or endearment. A crucial component to long periods of over exerting exercise/weight training.

This is great for body builders but what about those of you not hitting the gym every day. Well Glutamine has also been recommended as a way to promote neuro activity. In the same way it works to provide energy to your muscles it also provides power to your brain. The gamma-aminobutyric acid (GABA) neurotransmitters in your brain benefit from this glutamine and could even yield your bodies craving for sugar in moments of mental excursion.

Choosing the right glutamine

  • Unless your bodybuilding or exercising regularly you are probably getting enough Glutamine from regular protein sources like meat fish or tofu.
  • For those who do fit the description above opt in for the powdered form of glutamine since it increases the ease of absorption.
  • Studies have shown optimal daily intake between 10 and 20 grams per day



Nootropic Amino  -L-Carnitine (Tartrate & Acetyl )

Another essential amino acid making it to the top 6 list is Carnitine. There are a few different forms of this amino acid, each should be looked at carefully since they are supplemented for different reasons with varying effects on your body. The naturally produced form is L-carnitine tartrate which is created within your body as well as synthetically for those looking to increase their L-Carnitine tartrate intake. The other most popular form and more significant in the nootropic community is Acetyl-L-carnitine which comes only in synthetic form.

L-carnitine tartrate works to provide your body with more energy efficiently. This can translate into mental performance but is commonly used for those looking for an extra set at the gym or the motivation to get off the couch. This boost of energy is different in the sense of a caffeine supplement since it makes better use of the available energy you already have. It is this optimizing effect that has people taking notice for other uses than at the gym.

The synthesized form known as Acetyl L-Carnitine has been turning heads for its nootropic ability that differs from its partnering supplement. Acetyl L carnitine has been shown to improve cognitive performance by increasing mood levels and the sense of motivation. This compound has the ability to directly affect the mitochondria which are responsible for generating energy at a cellular level. Furthermore Acetyl L-Carnitine can aid in weight loss if taken with the proper amount of DHA and ALA combined with a low carb diet. How Acetyl-L carnitine differs from the primary form is its ability the break the blood brain barrier leading to a greater effect on cognitive performance and has even shown its ability to detoxify heavy metals from the brain.


  • There are a few different types of carnitine each with their own effect.
  • The main supplemented versions are L-Carnitine Tartrate and Acetyl-L-carnitine.
  • L-Carnitine Tartrate is synthesized in your body while Acetyl-L-Carnitine is synthetic.
  • They both help your cells use the available energy more efficiently.
  • Acetyl L-Carnitine can improve your mood and motivation quickly through its ability to break the blood brain barrier.
  • They have both been used to accelerate weight loss goals.
  • Acetyl-L-Carnitine can help remove heavy metals from the brain.
  • Both L-Carnitines are especially important for vegans and those who eat fewer Legumes.



Nootropic Amino  -Tryptophan

Probably one of the most well-known mentally calming amino acids found in nature would have to be tryptophan. If you are not familiar with this one think back to all the times you blamed the turkey in a christmas dinner for draining the energy out of the room. The culprit in those situations is actually the tryptophan going to work.

When you’re not expected to feel a calming or even tiring mood tryptophan can be a bit of a buzz kill. In the nootropic sense though it can work wonders for calming an anxieties while alleviating depressions.

Tryptophan works by converting within your body into 5 HTP which is then transformed into serotonin. Serotonin is a hormone that transfers neurological signals in your brain and translates into a better mood for yourself. Tryptophan is one of the essential amino acids your body can not create and it is for this reason you should be getting the proper amount through the food you are eating or supplementing in cases where there isn’t enough.


  • Tryptophan is commonly found in milk and turkey.
  • It is associated with a calming sedative effect.
  • It is a precursor to serotonin which leads to improved moods.
  • Tryptophan has been used to treat ADHD, anxiety and Depression.
  • Has Nootropic qualities for the way it creates neurological signals in the brain.



Amino acids are a vital form of proteins building blocks and sustaining life, some more essential than others with varying effects on your bodily functions. Hopefully this list has given you the proper information needed to supply yourself with the types of brain supplements that work to improve cognitive function for whatever task or project comes next.
