                                                    5HTP is an essential amino acid that is critical for the formation of many life-giving bio-molecules, including structural proteins, enzymes, and the neurotransmitters, serotonin and melatonin.

5-HTP is also the least abundant amino acid in our diet.  Because of this, 5-Htp is widely used to correct mental and bodily disorders such as Depression, Obesity, Alcoholism, PMS, Anxiety, Panic, Fibromyalgia, Insomnia, Migraines, Aggressiveness, Weight Loss, Food Cravings, Etc., all of which can be caused by serotonin deficiency.

Unlike 5-HTP L-Tryptophan has many other uses in the body.  It can be converted to niacin.  It is a required precursor to the kynurenines, a family of biochemicals that help regulate the immune system.  As an essential amino acid, L-Tryptophan is required for your body to work properly.

Even though L-Tryptophan and 5HTP are metabolized to serotonin along the same biochemical pathway, individual differences in metabolism can cause significant differences in effectiveness.


L-Tryptophan is a natural amino acid that is the precursor to serotonin and melatonin, which is a neurohormone that affects the body’s ability to sleep, relax and feel good. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. L-Tryptophan also supports immune functions because it is the body's precursor to the kynurenines that regulate immunity. If needed, L-tryptophan coverts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system.
