The body creates norepinephrine as follows:
Phenylalanine-> Tyrosine-> L-dopa-> Dopamine -> Epinephrine-> Norepinephrine.
In general, the effect of norepinephrine on the target organ changes the body in a way that leads more to active body movement, often generating increased energy use and increased wear and tear (R) costs.
PHENYLALANINE
It is an essential amino acid that must be taken through the diet because the body cannot synthesize by itself but is needed for the production of tyrosine secreted from the thyroid gland.
Except for phenylketonuria patients, which is seen one in 4000, it is essential that all people have a daily diet.
Important Note: Phenylalanine nourishes cancer cells, just like sugar.
Most protein-rich foods contain good amounts of L-phenylalanine. These include the following foods:
• Eggs
• Milk and milk products
Legumes (beans and peanuts)
• Sunflower and sesame seeds
• Red meat and poultry
• The fish
Eating a variety of good protein sources will provide you with optimal phenylalanine intake
TYROSINE
Tyrosine is often used as a precursor to the class of neurotransmitters called catecholamines (dopamine, norepinephrine and epinephrine) in the brain.
High tyrosine levels increase the production of these neurotransmitters if our body needs more than these.
As a result of tyrosine consumption, the increase of catecholamine levels enables antioxidant properties to be protected and protect brain cells from oxidative damage (neuroprotective activity). Tyrosine can also help prevent dementia, parkinson or other diseases related to the nervous system.
. It reduces stress
. Makes one feel good
. Increases attention and concentration
. Improves cognitive functions
. Has effects to protect memory
L-DOPA
Levodopa is the precursor of dopamine, since dopamine does not cross the blood brain barrier, levodopa is given instead.
If you suffer from insomnia as well as depression, norepinephrinergic therapy is likely to worsen your condition.
