Been taking Tryptophan for about four years, changed my life when I found it
But effectively yes, I would run out, not order any for a few weeks / months then order some.
I see you've mentioned you seem to have developed a tolerance. Mind sharing more detail on the above such as how long you have been taking the above and the dosage used for each, as well as the notice of tolerance of each etc.?
and L-Tryptophan (about a teaspoon) mixed with oil in the most evenings
I go on and off them sometimes if they're not doing much
My guess is people with stress/gastro issues don't get the adequate serotonin for "normality"
If your gut has issues with absorbing fructose, then the free fructose seems to connect with tryptophan, which hinders the tryptophan from being absorbed.
