I tested low in serotonin in a saliva test from my functional medicine physician.
The reason is I am battling painful lyme and bartonella from tick bites. This amazing supplement lets my body work to make the serotonin I need. This negates the need for being on a prescription which does not address the root cause. Low serotonin. This 5HTP is therapeutic for me to function better and to sleep better. I hope this helps. Sicncerely, Ginny B.
