Pure L-Tryptophan

by FTH Nutraceuticals


L-Tryptophan has helped millions of people find a deeper more relaxing sleep, and help to reduce stress and physical pain. L Tryptophan is the precursor to Serotonin, a neurotransmitter in the brain, which is deficient in depression and naturally enhances sleep. Each capsule of Pure L-Tryptophan has 500 mg. of the highest quality USP Pharmaceutical Pure Grade L - Tryptophan available for professional use.

Tryptophan and sleep

Sleep Deprivation is a serious concern for many, and low Serotonin levels are often the cause of this problem. Tryptophan converts to Serotonin helping to induce relaxation and naturally enhancing sleep. Two capsules 30 minutes prior to bedtime are recommended. If necessary, Tryptophan can be taken during the night. In extreme problems, Tryptophan should be taken early evening and again at bedtime. Vitamin B-6, along with increasing dietary complex carbohydrates are important for proper metabolism and increasing effectiveness.

Mood enhancement

It has been well documented that low Serotonin levels and low Tryptophan levels have been associated with depression. Tryptophan naturally converts to this neurotransmitter. If depression also involves Catecholamine biochemistry, then taking Tryptophan in a regimen along with Tyrosine is recommended. Since they compete for uptake in the brain, and because Tryptophan induces sleep, it is recommended that Tryptophan be taken prior to dinner and again prior to bedtime. Tyrosine should be taken prior to breakfast and mid morning as well.

Other aspects of l-tryptophan and serotonin autism

Low levels of Tryptophan have been documented in autistic children, indicating that there may be a defect in the Tryptophan-Serotonin metabolism in the brain.

Pain tolerance

Increased Serotonin levels have an effect on increasing pain tolerance, especially for chronic pain caused from Arthritis and Lower Back Problems. In one study, Tryptophan was administered at the dose of 1-500 mg. capsule every 2 1/2 hours(total 6 per day) resulting in a 50% reduction in pain intensity. A high carbohydrate diet is recommended to increase Tryptophan metabolism, along with Vitamin B-6. D-Phenylalanine is also recommended in some cases to enhance results and supplementation with Montiff D Phenyl Relief (D Phenylalanine) is suggested.

Appetite control

Some studies suggest that administering Tryptophan helps control appetite, for those who are on a weight reduction program.

Chemical addiction

Cocaine addiction causes a deficiency of L-Dopamine and causes both Cathecholamine and Serotonin neurotransmitters imbalances. Administering L-Tyrosine and L-Tryptophan can help increase these neurotransmitters. This regimen has been used in chemical dependency units, along with conventional therapies. Tryptophan may also be helpful for those addicted to nicotine.

Jet lag

Supplementing with L-Tryptophan is recommended for those who travel and experience jet lag. It is most effective when taken in conjunction with L-Tyrosine to increase Catecholamine as well as Serotonin production.

Safety of l-tryptophan

Volumes of research have been published on the effectiveness and safety on the supplementation of Tryptophan for deficiencies related to sleep disorders, depression, pain tolerance and other benefits for more than 30 years. However, in 1989 a disorder known as EMS was attributed to a contaminated batch of Tryptophan produced by a Japanese company and distributed to many other companies for sale.

FTH Nutraceuticals supplies only the highest quality pure L-Tryptophan which has been carefully evaluated. It does not have any contaminates or peak "x" abnormalities and it has been safely used for many years to benefit those with Tryptophan and Serotonin deficiencies.
