N Acetyl Tyrosine, Jarrow, Brain health

N-Acetyl Tyrosine is the active form of the amino acid Tyrosine. It has gone through acetylation, a process that improves its solubility and stability. N-Acetyl Tyrosine can support brain health and functions by acting as a precursor to the neurotransmitters dopamine, epinephrine, and norepinephrine. The body converts it to tyrosine for mood regulation, stress management, and normal gland function.

  • N-Acetyl Tyrosine supports normal brain functions. It is involved in the production of the three catecholamines or neurotransmitters. Dopamine, epinephrine, and norepinephrine which are brain chemicals that controls mood, behaviour, appetite, pain sensitivity, and stress response. Low tyrosine levels in the brain can lead to depression, anxiety, loss of focus, and memory loss.
  • By promoting healthy adrenal functions, N-Acetyl Tyrosine/ tyrosine help the body with its natural anti-stress responses. The poor functioning of the adrenal glands can lead to more production of the stress hormone cortisol, which can lead to chronic fatigue syndrome.
  • Jarrow Formula N-Acetyl Tyrosine can help protect the body from the harmful effects of low tyrosine in the blood. Conditions related to tyrosine deficiency include ADHD, schizophrenia, low blood pressure, and hypothyroidism.
  • According to a study, tyrosine supplements can help promote mental alertness even when people gets minimal amount of sleep. Sleep deprived individuals can often lose their consciousness and experience mental sluggishness.
  • When combined with 5-HTP supplements, N-Acetyl Tyrosine can be a potent mood support formula. It can help promote healthy emotional coping by balancing neurotransmitter levels. Depression and other mood disorders are usually effects of imbalance in neurotransmitter concentrations in the brain.
  • Researches suggest that more tyrosine in the blood supports healthy memory and cognitive functions even when under stress.

N-Acetyl Tyrosine is the more soluble and stable form of the non-essential amino acid tyrosine. This acetylated form of tyrosine is purported to be more effective than L-tyrosine/ tyrosine. N-Acetyl Tyrosine is up to 20 times more absorbable in water and it has the ability to cross the blood brain barrier to produce direct effects on the brain. The body readily converts N-Acetyl Tyrosine to tyrosine, increasing blood concentration of this very important building block of protein. The body uses tyrosine in the production of neurotransmitters, specifically dopamine, epinephrine, and norepinephrine. These brain chemicals control cognitive functions and emotional health. Healthy tyrosine supply from N-Acetyl Tyrosine supplements can naturally support mental alertness, healthy memory, and focus, even during stress and sleep deprivation. Deficiency of all or one of these neurotransmitters has been linked to a wide variety of mental disorders including depression, ADHD, and schizophrenia. Other reported side effects of tyrosine deficiency are low libido, sluggish metabolism, and chronic fatigue.
