New MOOD™ has several advantages over a regular 5-HTP supplement. First of all, each dose has a full 100mg of top quality, and lab verified 5-HTP. In order for 5-HTP to be converted to serotonin, the body needs ample supply of pyridoxine, or vitamin B-6. Furthermore, our formula also contains L-Tryptophan which is one step earlier on the reaction chain of serotonin production, which in effect acts as a time release serotonin builder. Check out onnit.com/serotonin for more details. Lastly we have a host of supportive herbs and nutrients that assist in mood regulation and relaxation that provide significant acute and long term advantages over 5-HTP alone.
