    Tyrosine is a non-essential amino acid made from Phenylalanine in the body‚ and found in foods such as lima beans‚ pumpkinseeds‚ almonds‚ avocados‚ bananas and dairy products. It is extremely important for neurological health‚ since it is the precursor for catecholamine neurotransmitters in the brain. The biochemical conversion of Tyrosine is Dopa‚ then Dopamine‚ Norepinephrine‚ and Epinephrine. Pyridoxal 5'PhosphatE‚ the active form of B6‚ is necessary for this conversion. Low levels of Tyrosine in the blood show a direct correlation to depression and anxiety. Tyrosine is also a precursor to Thyroxine‚ and aids in the production of melanin as well. Abnormal metabolism of Tyrosine is associated with Albinism‚ since there is a deficiency of melanin production in this condition.

    Tyrosine is the precursor for catecholamine neurotransmitters in the brain‚ which effect mood. Deficiencies of Tyrosine can result in inadequate norepinephrine in the brain‚ which causes depression. Many medical studies have confirmed that low levels of Tyrosine in the blood are associated with depression. Research has noted marked improvement in depressed individuals‚ analogous to low catecholamine levels‚ when given oral supplementation of Tyrosine.

    Reduced catecholamine levels have also been associated with behavioral changes related to stress. Research studies have documented that Tyrosine supplementation has resulted in decreased anxiety and improvement in mood in individuals experiencing stress. Studies further noted that Tyrosine supplementation improved other symptoms of stress‚ including the ability to concentrate‚ headaches and muscle discomfort.

    The chronic use of cocaine interferes with catecholamine biochemistry in the brain causing a chemical imbalance by reducing Dopamine (DA) and Norepinephrine (NA) metabolism. These chemical imbalances are associated with the withdrawal symptoms of drug craving‚ depression‚ anxiety‚ and irritability. Tyrosine levels are measurably low in those addicted to cocaine and supplementation of Tyrosine improves catecholamine biochemistry and assists in decreased symptoms of withdrawal.

    Narcolepsy‚ effecting over 250‚000 people in the U.S.‚ is a sleeping disorder in which individuals fall asleep suddenly without any warning. This is extremely disconcerting and dangerous as well. Narcofepsy has been associated with a Dopamine abnormality‚ and since the precursor to Dopamine is Tyrosine‚ supplementation may be beneficial with this condition. In the studies conducted on those with this disorder‚ there was significant improvement when Tyrosine was administered. Results were decreased when vitamin B-6 was included in the protocol‚ indicating that Narcoleptics should not be given B-6 with Tyrosine.

    Tyrosine is the precursor for Thyroxine production by attaching to iodine atoms to form active thyroid hormones. Low levels of Tyrosine have been related to hypothyroidism.

    Not quite "pure"

    I should have zoomed in on the image, because Pure L-Throsine by Montiff contains the excipients cellulose, magnesium stearate, and silica dioxide. The site does not list this under ingredients, where as other supplements list the excipients under the ingredients tab. I wish I could return it, but now I have a large open bottle of the stuff.


      Inexpensive. subjectively, I felt it was not as potent as other L-Tyrosine products I've taken, but still produced the anti-stress effects after sleep deprivation that I was looking for.


      The excipients which I am sensitive to.
