Accepted Answer

There is none: Tyrosine is a precursor of ldopa which make dopamine. It should only be used as part of a balanced program to resort the neurotransmitters and should be guided by a knowlegable doctor  who manages patients with neurotransmitter problems.

Question 2

can you od on l. tyrosine?

Accepted Answer

Yes but rare: L- tyrosine is an amino acid(building blocks of protein), that is not considered essential because the body can make it from other Amino Acids like phenylalanine.  It is part of the production chain of many neurotransmiter (substances that transmit the message from nerve cell) and also important in the production of melanin which gives us our. Od rarely reported but should not be taken in large am.

Question 3

what are the uses for l-tyrosine and 5-htp?

Accepted Answer

Alertness, and Sleep: L-tyrosine is a stimulatory neurotransmitter precursor.  5htp is an inhibitory neurotransmitter precursor.  Both may be helpful as antidepressants when appropriately used.  L-tyrosine is best taken in the morning or during the day; 5htp is best taken (in high doses--150 mg) at bedtime, or lower doses (50 mg) during the day.

Question 4

is 5-htp and l-tyrosine the same or different?

Accepted Answer

Different: 5htp is a precursor of serotonin, an inhibitory neurotransmitter.  L-tyrosine is a precursor of the dopaminergic neurotransmitters Epinephrine and norepinephrine, which are stimulatory neurotransmitters.  Although both 5htp and l-tyrosine may act as anti-depressants, they act in completely different ways.  5htp is best taken at bedtime; l-tyrosine should be taken in the am or during the day.

Question 5

is it okay to take 5-htp and l-tyrosine together?

Accepted Answer

HTP/Tyrosine: Not advised, since both can increase serotonin in your system.

Question 6

can l tyrosine cause prolactin levels to increase?

Accepted Answer

Should not: If it has any effect at all, tyrosine should decrease prolactin.  It is the immediate precursor for dopamine, which is released from the hypothalamus onto the pituitary and, among other things, affects prolacting release; however, the effect of increased Dopamine would be to decrease prolactin.  Drugs that block Dopamine receptors (antipsychotics) can cause marked increases in prolactin levels.

Question 7

is 5-htp and l-tyrosine the same thing or different?

Accepted Answer

Different: These are Amino Acids that the body uises in ver specific ways. Unbalanced use of these Amino Acid have the ability to do far more harm than good. They really should only be managed by physicians who are fully aware of how to use them properly.

Question 10

l - tyrosine is helpful with hyperthyroidism?

Accepted Answer

NO: Tyrosine is aminoacid  precursor for synthesis of  thyroid hormones :  T4 &amp; T3 (liothyronine). 
2 molecules of  Iodo tyrosine  ( Iodide + Tyrosine) = Diiodotyrosine..( DIT )

DIT + DIT =  Thyroxine - T4
DIT + Mono Iodotyrosine  (MIT )  =  T3 (liothyronine).
