 Tryptophan is an essential nutrient - essential for life. This amino acid is a component of protein, found naturally in all bone, muscle, and tissue. Tryptophan is most concentrated in the brain. There, it is the raw material that is converted into hormones such as melatonin - and the powerful neurotransmitter serotonin.  Tryptophan is a key to our mood chemistry. Here's the link: This amino acid is required to make serotonin. Serotonin is absolutely essential to maintain stable moods - the feel-good chemistry that gives us a sense of emotional stability and well-being. When people do not have enough serotonin, they tend toward depression, irritability, or anxiety. They are more easily affected by stress, emotional issues, PMS, and sensitivity to pain. Increasing serotonin levels often restores a sense of emotional balance. Research has established clearly the pivotal role of serotonin in mood, sleep, and other functions of the nervous system. Thousands of research studies on depression, anxiety, and insomnia have also shown a connection between low serotonin and its precursor, tryptophan. We know that millions of people have used tryptophan for these conditions. Tryptophan's ability to support serotonin levels reliably is what makes this supplement so incredibly important. Depression and insomnia are now at epidemic levels. Depression currently affects more than 20 million Americans. Seven in 10 say they don't get enough sleep. This suggests that low levels of serotonin may be very common.  Another of the important uses of tryptophan is its ability to promote natural sleep. We know that serotonin is essential for sleep. When levels of serotonin are low, there can be difficulty falling asleep - and staying asleep. It is the soothing effects of this neurotransmitter that signal the body to relax, allowing deep sleep to occur. A tryptophan supplement can be taken in the evening to gently encourage natural sleep.  The tryptophan supplements available on this site meet the highest standards set by the FDA - CP2000. The level of purity of these products exceeds the requirements for medications (USP - U.S. Pharmaceutical grade). They have been tested and meet the CP 2000 standard of purity required of intravenous pharmaceutical medication. This is a higher standard than that required for prescription medication. Currently, only a few sources in the United States have met these FDA purity standards and are authorized to market tryptophan. Other than these few vendors, whose products have been evaluated, all the tryptophan available on the Internet is either: . 5-HTP, which is less effective, or . Veterinary grade, not intended for human consumption. In sum, this site is one of the very few sources of pharmaceutical-grade tryptophan currently available through the Internet. The FDA has performed multiple evaluations of these products, confirming the purity of this tryptophan through extensive testing.
Our moods and sleep are regulated by powerful brain chemistry, particularly serotonin, one of our most important neurotransmitters. Low serotonin levels have been identified as a cause of depression in hundreds of research studies. Serotonin is made in the brain from tryptophan, an essential amino acid. Tryptophan is the raw material the brain requires to make serotonin. Tryptophan is a component of most proteins. Unfortunately, stress can deplete tryptophan. A number of other factors can also lead to tryptophan deficiencies, which in turn result in low levels of serotonin. Extensive research has shown that tryptophan supplements raise serotonin levels. By using a nutritional supplement, we are simply providing the raw material the body needs to produce serotonin. Raising serotonin is a vital step in addressing depression, anxiety, PMS mood swings, and insomnia. The ability of tryptophan to support the body's production of this absolutely critical neurotransmitter is what makes tryptophan such an important, sought-after nutritional product.
