Amplifying Brain Function and Stress Resilience

L-Tyrosine is a non-essential amino acid that plays a pivotal role in synthesizing proteins and producing crucial neurotransmitters in the body. L-Tyrosine has garnered attention as a powder-form dietary supplement for its potential cognitive and physiological benefits.

  • Neurotransmitter Production: L-Tyrosine is a precursor for dopamine, norepinephrine, and epinephrine neurotransmitters. These neurotransmitters are vital for mood regulation, alertness, and overall brain function.
  • Cognitive Enhancement: Under stress and sleep deprivation conditions, L-Tyrosine supplementation can potentially enhance cognitive flexibility and overall performance, helping the brain adapt to challenging situations.
  • Stress Support: By bolstering neurotransmitter levels, L-Tyrosine may help mitigate the effects of stress, especially during acute or prolonged challenges.
  • Thyroid Function: Tyrosine is also involved in the production of thyroid hormones, which regulate metabolism and overall energy levels.
  • Safety and Tolerance: L-Tyrosine is generally well-tolerated at recommended doses. However, potential side effects, though rare, can include nausea, headache, and fatigue.
  • Flexible Dosage Forms: The powder form of L-Tyrosine offers flexibility in dosing and can be seamlessly mixed with water, juices, or incorporated into shakes.


  1. General Supplementation: For supporting neurotransmitter production and overall well-being: 500mg to 1g daily, often taken in the morning or early afternoon.
  2. Thyroid Health: The dose for supporting thyroid function can vary but typically falls within the range of 500mg to 2g daily. However, it's essential to consult a healthcare professional for specific guidelines.
  3. Safety and Tolerance: L-Tyrosine is generally well-tolerated at recommended doses. Starting with a lower dose and monitoring for any side effects is advisable. Potential side effects, although rare, can include gastrointestinal discomfort, increased heart rate, headache, and insomnia, especially if taken late in the day.
  4. Form and Timing: L-Tyrosine powder allows for easy dose adjustment and can be mixed with water, juice, or other beverages. Because of its potential to increase alertness, taking L-Tyrosine in the morning or early afternoon is often recommended to avoid sleep disturbances.
