5-HTP 100 provides a concentrated natural source of the amino acid, 5-hydroxytryptophan (5-HTP) from Griffonia simplicifolia seed. 5-HTP is a metabolic intermediate of the essential amino acid tryptophan and is the immediate precursor to the important neurotransmitter serotonin. As a result, 5-HTP plays an essential role in our body’s synthesis of serotonin, which helps to enhance sleep quality while also promoting positive mood and supporting digestive system function and appetite control. Serotonin levels have been shown to be associated with the regulation of sleep, mood, appetite and the digestive process, which makes supplementing 5-HTP an important means of supporting these essential functions. Clinical research has shown that 5-HTP has the ability to cross the blood-brain barrier providing a direct means of promoting serotonin production and its benefits. Furthermore, 5-HTP also supports melatonin synthesis, which helps to regulate normal sleep schedule

Helps my depression!!
I could not be without Andrew's 5-HTP. I don't take them every day. But when my depression peaks and life seems dark, I take Andrew's 5-HTP and know I just have to hang on for 1 1/2 to 2 hours and I gradually feel better, brighter and I will be ok!!! I was diagnosed with clinical depression in 2013 and that doctor felt I had it my entire life. He wanted me on daily medication the rest of my life but I decided to try therapy first. 5-HTP has been the help when I needed it and Andrew's is the best for me! My family and I have been using Andrew Lessman supplements for over 20 years!! Thank you Andrew for your incredible products!!

My Back Loosened Up...
Dear Andrew Lessman Loves, I took two of these capsules and my whole back loosened up when I woke up... I had no idea it was tight... I just knew it was hard for my body to relax before going to bed...

Did not work
First off, I love Andrew Lessman's vitamins and supplements. I have been taking them for a year. I take quite a few; however, this one did not help me at all. In fact, it gave me insomnia and a HORRIBLE headache. I wanted to give it a fair chance, so I took it for 8 months to see if it needed to build up in my system, and it did not. First one that didn't work for me. Ugh.
