I want to know if it is true that the amino acid l-tyrosine may work as an antidepressant, and how to take (dose, time).

True is false: The answer is " it depends on your response to it" . True in medicine depends on strict parameters of number of positive responses versus negative or null responses. There are few or any controlled studies of L- tyrosine compared to placebo ( a sugar pill) and to antidepressants. I hope this is clear enough. Thanks!

Amino acid: L tyrosine may have minimal side effects to improve energy levels: it is not an antidepressant- never has been.
