5-HTP is a safe precursor to serotonin, the “happy neurotransmitter”, which may improve and uplift your mood. At night time, serotonin itself undergoes further conversion in order to produce melatonin, which will help you fall asleep. Therefore, I will take 5-HTP during the day, if I am trying to lift my mood or at night to promote sleep. A small carbohydrate meal will promote serotonin synthesis.
Did you know that special cells within our gut lining produce 90% of our total body serotonin? You also need to know that serotonin is responsible for bone health and bowel motility.
