Hi Billye

my son used 5HTP very successfully thru a rough patch with his OCD/Tourette

it also really helped him with sleep.
it is linked in the melotonin and serotonin pathways

my husband could not handle it tho (also has TS) but seems to do better on the pure tryptophan. I have not personally tried either.

hope that helps a bit

are you considering it?

oh yes, the warnings are old and related to contamination of a batch of tryptophan, because of the source. Itwas withdrawn by the FDA at one time but is now approved again, as it was the source and not the substance that was at fault I believe.
5HTP has always been available tho
