Side effects 5-HTP tyrosine dopa GI
upset cysteine: Tyrosine and dopa deplete the sulfur amino acids if
proper levels of cysteine are not
administered with their use.
All people
taking a combination of
5-HTP, tyrosine, levodopa, and cysteine
precursors of the serotonin, dopamine, norepinephrine
and epinephrine systems need to take
proper amounts of cysteine two pills
three times a day to prevent
depletion of the sulfur amino acid
system. It has been observed in clinics
that 20% of people taking cysteine in
the early morning experience GI upset.
The mechanism of action of this problem
is unknown but the treatment is to
instruct people at the start of
treatment to take the cysteine at noon,
4 or 5 PM, and bed time. From time to
time you will run into a person who did
not understand the instructions and is
taking cysteine in the AM with no
problems, this is fine.
