In this case, used as a source of serotonin - deficiency of which was causing constipation; but, yes, it does also promote sleep
I am not using it for relaxation - in fact I slightly dislike its soporific effect, and hope this will diminish with use. I switched from 5-HTP to L-Tryptophan, because one should not take 5-HTP for more than 8 (maybe 12) weeks maximum, as doing so will deplete dopamine (after which the 5-HTP is also no longer effective). I was using 5-HTP as a natural prokinetic, though I know it is touted as an aid to sleep/relaxation, as is L-Tryptophan. My problem was lack of intestinal peristalsis and ensuing constipation, both in relation to SIBO-C. 100mg of 5-HTP each night provided me with peristalsis/normal bowel movements, because one's body makes serotonin of 5-HTP, and 85-90% of the body's serotonin is used in the gut for peristalsis. Tryptophan can also be converted, by the body, into serotonin (though it can also be made into other things, such as niacin). My hope was that 1500mg L-Tryptophan, nightly, might be an adequate replacement for the 500mg 5-HTP, relative to maintaining intestinal peristalsis & correcting constipation due to lack of peristalsis. 30 days into the experiment, it does seem to be working.
