Promotes brain serotonin levels to support emotional well-being, healthy eating behavior, and healthy sleep*.

5-Hydroxytryptophan (5-HTP) is an intermediate in the natural synthesis of the essential amino acid, tryptophan, to serotonin. The enzyme tryptophan hydroxylase adds a hydroxyl group (OH) to tryptophan, forming the 5-HTP intermediate. In the body, it converts to serotonin with the removal of a carboxyl group (COOH) by a second enzyme. Serotonin is an important neurotransmitter involved in the regulation of endocrine and brain activity responsible for emotion, appetite, and sleep/wake cycles. In clinical studies, the administration of 5-HTP supported serotonin production. The 5-HTP supplied in this supplement is derived from the Griffonia simplicifolia plant.*

Helps with mood a little

Helps my mood not a whole lot maybe a 20 percent jump

Caution ????

This supplement caused me extreme cramping, nausea and vomiting. I also have a horrible headache. Unfortunately my return window has closed, so $55 down the drain. From the web: Side effects of 5-HTP are generally mild and may include nausea, heartburn, gas, feelings of fullness, and rumbling sensations in some people

Great product. Gives me deep sleep.

I have problems sleeping due to pain. I started taking Pure 5HTP at night with GABA 750. I slept great and had energy during the day. I recently ran out, and forgot about reordering. After about 2 weeks of being off it, I was back to being to exhausted to get out of bed. From now on Im on auto ship. For me it takes a little bit to build up in my system, so dont give up after just a few days of taken it

be careful

Everyone says how good 5-HTP is and I was recommended it by a medical medium practitioner. I've taken low doses (5mgs) before with no reaction. After taking this I got SUPER depressed and cried for 2 days. Stopped taking it and was fine. I recommend that people really do their research before taking things that mess with their brain chemistry
