In 1901, Sir Frederick Gowland discovered L‑Tryptophan--an essential amino acid that Gowland showed was absolutely necessary to sustain life.  Now, over one hundred years later, the need for L‑Tryptophan continues to grow. It is still absolutely necessary to sustain life. And, in today's intense, high-stress world, L‑Tryptophan may be even more essential. Only L‑Tryptophan can increase your body's supply of serotonin, the neurotransmitter that lets your mind be calm in the face of overwhelming tension, anxiety and uncertainty. Only L‑Tryptophan promotes the natural, restful sleep that comes when you have enough serotonin. And, only L‑Tryptophan is the essential building block for many life-giving biomolecules, including structural proteins, enzymes and the neurotransmitters, serotonin and melatonin.

• Relieves occasional sleeplessness
• Soothes nervous irritability
• Relieves muscle pain from exercise
• Reduces premenstrual symptoms
• Supports a good mood
• Helps relieve the craving for carbohydrates.

Because L‑Tryptophan is the least abundant amino acid in our diet, it should be no surprise that L‑Tryptophan supplements have been widely used to correct deficiencies for more than a quarter of a century by doctors in the United States and Europe. Psychiatrists, medical doctors, and nutritionists, alike, have long recognized the importance of pure L‑Tryptophan for maintaining good health, relieving poor mood and irritability, reducing the craving for carbohydrates and normalizing sleep.

Recent research has shown that the communication between cells of your body is far more intricate and important than ever imagined. Everything from your mood to your appetite is based on the free-flow of information between these cells. Serotonin is one of the most abundant cell-to-cell communicators, called neurotransmitters, in your body, and only L‑Tryptophan is the essential amino acid that makes serotonin. Since serotonin is one of the most abundant neurotransmitters, and L‑Tryptophan is the least abundant amino acid, supplementation is often required to maintain optimal health.

For occasional sleeplessness, many respected physicians have their patients take two 500 mg capsules an hour before bedtime – sometimes adding an extra capsule right at bedtime for those who have trouble staying asleep. L‑Tryptophan can also help those who fall asleep readily, but occasionally wake-up too early. A capsule or two by the bedside, that can be easily taken, has been a real life-saver for those nights when you're stirred awake at three A.M.

To support a good mood, L‑Tryptophan can be taken at any time of the day, but it's most commonly taken in the evening. After all, a good night's sleep is often the crucial first step towards chasing away depression. For a great mood, to relieve premenstrual symptoms and to break the cycle of muscle pain from exercise, knowledgeable physicians suggest starting with two capsules, then increasing the dose to one capsule for every 50 pounds of body weight.

Many patients get a great night's sleep or “knock-out” the blues with L‑Tryptophan without giving diet a second thought. For those of you who want to fine tune these benefits, a little juice or carbohydrate snack helps push L‑Tryptophan into the brain where it can do the most good. Another trick is for the patient to avoid proteins within an hour of taking L‑Tryptophan capsules. because proteins compete with L‑Tryptophan for absorption, more L‑Tryptophan will pass the blood-brain-barrier if patients avoid eating proteins at the same time.
