Product Overview

500 mg - 90 Capsules

Mood, Relaxation, Sleep

L-Tryptophan is an amino acid that is used to promote relaxation, and is taken before sleep or prior to or during anxiety provoking situations. L-Tryptophan can also be used to help prevent carbohydrate cravings.

 LTryptophan is found in many proteins, enzymes and neurotransmitters throughout your body, including serotonin and melatonin. That’s right, it is from LTryptophan alone that your body naturally makes serotonin and melatonin. For this reason, no other amino acid, vitamin, mineral, herb or drug can take the place of LTryptophan.

The fact that this amino acid is absolutely critical to your health is confirmed by the fact that LTryptophan is routinely added to baby formulas, where it is essential for growth, and to hospital intravenous solutions (IV’s), where it is essential to life. Furthermore, plasma amino-acid analysis of hundreds of patients demonstrates that LTryptophan is the amino acid most deficient in our diet. As demonstrated by Dr. Charles Jarowski, former head of Research and Development at Pfizer, Inc., when an essential amino acid such as LTryptophan is in short supply, a host of health conditions begin to surface, often emotional ones, first.

Because LTryptophan is the amino acid most lacking in our diet, it should be no surprise that LTryptophan supplements have been widely used to correct deficiencies for more than thirty years by doctors in the United States and Europe. Psychiatrists, medical doctors, and nutritionists, alike, have long recognized the value of pure LTryptophan for maintaining good health, promoting a cheerful mood, relieving irritability, reducing the craving for sweets and carbohydrates, and encouraging normal, healthy sleep.

LTryptophan and weight loss:
During dieting, LTryptophan levels and serotonin levels drop dramatically. These low serotonin levels in overweight and obese patients are known to cause carbohydrate cravings and the resultant binge eating. Because brain and blood levels of serotonin, rise and fall depending on the amount of LTryptophan you consume, many health practitioners use LTryptophan to stop the cravings and help diets succeed.

Numerous clinical trials on overweight patients have demonstrated food cravings decrease, and food intake decreases when serotonin levels are high.

As medical awareness of the impact of LTryptophan on health continues to grow, it should be remembered that essential nutrients are not drugs, and it takes time to replenish your body’s supply, but it is well worth it! Some symptoms of an LTryptophan deficiency may disappear within days, but because essential amino acids are involved in nearly every bodily function, we always advise allowing 60 days for full benefit. Remember, there is no substitute for what your body really needs.
Suggested Use: 1 capsule three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3 capsules before bed.
