Best L-Tyrosine Supplements For Mental Performance 2019

To take on more challenges in life, we are left with no choice but to pick up on new skills amidst our stressful schedule. Learning and focusing can be difficult when you’re stressed and this is where taking L-Tyrosine supplements can help.

What Is L-Tyrosine

Best L Tyrosine Supplements

L-Tyrosine is a type of amino acids that enable the body to produce a series of organic compounds like dopamine, norepinephrine, and epinephrine. These chemicals are essential in promoting cognitive performance.

Besides that, L-Tyrosine also helps the adrenal, pineal and thyroid glands to function properly. You could get L-Tyrosine by taking foods likes dairy, fish, meats, eggs, oats, and nuts. The body could also produce tyrosine from another form of amino acids, phenylalanine.


How L Tyrosine Improves Brain Functions

One great reason for taking L-Tyrosine is its ability to enhance mental performance during periods of stress. L-Tyrosine is a precursor to catecholamine norepinephrine, a crucial neurotransmitter that supports cognitive performance in stressful conditions.

A publication by the Institute of Psychological Research and Leiden Institute for Brain and Cognition indicated that L-Tyrosine does indeed show promising results as a cognitive enhancer, although the result may vary amongst individuals.

While some studies are in favor of L-tyrosine, others cast doubts on the efficiency of this amino acid in boosting mental performance. More studies are needed to provide conclusive evidence of taking L-tyrosine for boosting cognitive functions.


Other Benefits Of L-Tyrosine

Besides being linked to promoting mental performance, L-Tyrosine may also offer health benefits in these areas.

  • Phenylketonuria – This is a condition where the body has difficulty producing sufficient amount of phenylalanine, which results in a deficiency of l-tyrosine. Taking L-Tyrosine supplement helps to increase the level of tyrosine in blood.
  • Stress – Taking L-tyrosine supplement helps individuals cope with both environmental and psychological stress. It replenishes catecholamines when a person is exposed to immense stressors.
  • Exercise Capacity – There seem to be mixed opinions on the effects on the taking of L-tyrosine prior to working out. One study that leans of the positive involves 8 healthy male participants and found that L-tyrosine increases exercise capacity in the heat.

How To Take L-Tyrosine Supplement

L-Tyrosine is available as an oral supplement. The dosage differs depending on the reason you’re taking the amino acid. Dosage recommendation is often recommended based on the body weight of the individual. For boosting mental performance, it is recommended that you’re taking 100 – 300 mg/kg of L-tyrosine supplement.

In cases of Phenylketonuria, a higher dosage of L-tyrosine may be recommended by your doctor. Your doctor would measure the level of tyrosine in the blood before prescribing the right dosage.


Precautions And Side Effects Of L-Tyrosine

L-tyrosine is present naturally in some foods. When taken as medicine at a higher dosage, some complications might appear. You’ll want to take note of side effects like nausea, fatigue, heartburn, and headache when taking L-tyrosine supplements.

Individuals who are taking thyroid hormone pill should not take L-tyrosine supplement as it may lead to an excessive level of thyroid hormone level in the body. The effectiveness of levodopa, a drug for treating Parkinson’s disease may be decreased by L-tyrosine.

Pregnant women, breastfeeding moms, and children should also avoid taking L-tyrosine as there are little studies conducted on the safety of these groups.

If you’re in doubt, talk to your doctor before taking L-tyrosine supplements.


How To Choose The Right L-Tyrosine Supplement

Choosing the right L-tyrosine supplement matters as each product may differ in quality. To ensure that you get the right L-tyrosine supplement, consider these factors before ordering.

  • Manufacturing Quality – It’s important for the supplement to be produced in a strictly controlled manufacturing environment. Look for manufacturers that practice GMP standards and subject the supplements to stringent 3rd party testing.
  • Purity – You’ll want your supplement to be free from harmful chemicals and additives. Labels like non-GMO and vegan-friendly help in ensuring the purity of the supplement.
  • Potency – The L-tyrosine supplement needs to be effective. This means taking the dosage into consideration and reviewing feedbacks from individuals who have taken the same product.

How Long Does It Take For L-Tyrosine To Work

You’re both physically and mentally stressed and you need to focus. Taking L-Tyrosine helps you to boost cognitive performance in a relatively short amount of time. The positive effects of L-tyrosine kick in when it enters your bloodstream. The duration can vary between 15 to 30 minutes after taking the supplement.


Where To Buy L-Tyrosine Supplements

There shouldn’t be any difficulties in getting L-tyrosine supplements. You can visit local pharmacies or wellness stores. Alternatively, you could save the hassle of commuting by ordering from major online retailers.
