Can you take tyrosine and 5 HTP together?

Some people may suggest taking 5-HTP along with a supplement that increases the amount of dopamine in the body, such as l-tyrosine or l-dopa.

Can you take DLPA and L-Tyrosine together?

In double-blind research, alcoholics treated with L-tyrosine combined with DLPA (D,L-phenylalanine), L-glutamine, prescription L-tryptophan, plus a multivitamin had reduced withdrawal symptoms and decreased stress. Does tyrosine deplete serotonin? l-tyrosine may deplete serotonin.

Accordingly, can l-tyrosine cross the blood-brain barrier?

Like its aromatic amino acid brethren (phenylalanine and tryptophan) tyrosine is a building block for neurotransmitter synthesis. Tyrosine readily crosses the blood-brain barrier and is the starting point for producing L-DOPA dopamine epinephrine and norepinephrine. Does tyrosine decrease serotonin? L-tyrosine may reduce serotonin, 5-HTP and sulphur amino acid. L-dopa may reduce serotonin, L-tryptophan L-tyrosine and sulphur-containing amino acids.

And another question, does l-tyrosine deplete dopamine?

Central dopamine function is reduced by decreasing the availability of the catecholamine precursor, tyrosine, using a tyrosine-free amino acid mixture containing multiple large neutral as well as branched chain amino-acids, which compete with tyrosine for uptake into the brain. Is L-tyrosine the same as 5-HTP? 5-hydroxytryptophan (5-HTP) is an essential amino acid precursor of serotonin, and the amino acid l-tyrosine is an essential precursor required for synthesis of dopamine.
