L-Dopa, L-Tyrosine, L-Tryptophan & Lithium Orotate

Lithium Orotate | L-Tyrosine | L-Dopa|L-Tryptophan


Lithium Orotate increases the levels of an enzyme tyrosine hydroxylase, which is involved in the production of the neurotransmitter dopamine.

Tyrosine Hydroxylase and Regulation of Dopamine Synthesis

Tyrosine hydroxylase is the rate-limiting enzyme of catecholamine biosynthesis; it uses tetrahydrobiopterin and molecular oxygen to convert tyrosine to DOPA. Its amino terminal 150 amino acids comprise a domain whose structure is involved in regulating the enzyme’s activity.


Dietary supplements that contain tyrosine and/or phenylalanine lead to alertness and arousal.

Nutritional therapies for mental disorders


L-Tryptophan is the sole precursor of serotonin. L-Tryptophan’s role in brain serotonin synthesis is critical for mood, behavior and cognition.

Serotonin is often referred to as the “happiness molecule”. Low serotonin levels can result in pain, insomnia, depression, seasonal affective disorder, and chronic fatigue.


L-Tyrosine stimulates the production of thyroid hormones T3 (triiodothyronine) and T4 (thyroxine) which are crucial in maintaining both overall physical and cognitive health.

L-Tyrosine can boost libido, memory, focus, concentration, mood, offers anti-depressant effects, and improves executive function in those with ADHD.

L-Tyrosine helps with…

  • Cognitive Stress. L-Tyrosine produces the catecholamine-triad of neurotransmitters dopaminenorepinephrine, and epinephrine. Sleep deprivation and extreme stressors like heat and cold can deplete catecholamine levels. L-Tyrosine restores them to preserve optimal cognition.
  • Neurotransmitters. L-Tyrosine is a required precursor for dopaminenorepinephrine, and epinephrine. As your dopamine levels increase, you’re better able to concentrate, organize your thoughts, and stay productive.
  • Attention Deficit Disorder (ADHD). L-Tyrosine can be an effective treatment for ADHD symptoms. It works in synergy with pharmaceutical drugs like Ritalin and Adderall by boosting extracellular levels of dopamine. Helping these drugs be more effective. And mitigating side effects like crashes when the drug wears off.

    L-DOPA is an amino acid synthesized in your brain by the amino acid l-tyrosine. L-DOPA is a precursor of several neurotransmitters including dopamine, epinephrine, and norepinephrine.

Mucuna Pruriens contains L-DOPA in high concentrations. And is used as a nootropic because dopamine itself cannot cross the blood-brain barrier.

Dopamine and norepinephrine are essential for memory, cognition, and a positive mood. A lack of either of these neurotransmitters can lead to a lower mood state, loss of memory, brain fog, poor energy, and more. And if left unchecked will eventually result in neurodegenerative diseases like Parkinson’s.

L-DOPA helps with…

  • Brain Health. L-DOPA helps to increase growth hormone levels in the brain. Boosting the production of neurons and glia cells affecting the formation of memories, and overall brain health.
  • Neurotransmitters. L-DOPA is a necessary precursor for your brain to make dopamine. And dopamine is then synthesized into the neurotransmitters epinephrine, and norepinephrine. Affecting cognition, learning, memory, movement, motivation and pleasure.
  • Neuroprotection. L-DOPA produces neuromelanins which are similar to the melanin pigment in your skin. In your brain they absorb toxic quinones, and chelate heavy metals like mercury and lead.
