L-Tyrosine question

I've taken it without problems

Tyrosine is a non-essential amino acid (it can be
synthesized within the body) that is a precursor for
epinephrine and norepinephrine. If a person were depressed
due to a shortage of epinephrine, then tyrosine might help,
but it should have no ill effect if there is no shortage,
i.e., it is not acting like prescription antidepressants
which block enzymes to increase neurotransmitter levels,
which potentially can result in too much of a
neurotransmitter being present in the brain.

The risk is the tanning.

A friend of mine is planning to take 500mg a day of L-
Tyrosine in order to get a better tan when we go to the
beach this summer. I checked this

stuff

out and while it does help your melanin for tanning, it
can also act as an anti-depressant. I told her this, and
she told me to investigate more.

Is this stuff safe to take? She has never suffered from
depression and isn't on any medication, so would taking
this pill cause mood-swings or

any

other ill effects?

Tyrosine can also be used by the body to manufacture
dopamine.
