Somniphan is a safe and effective sleep-aid that contains L-Tryptophan, GABA and Melatonin.

L-Tryptophan, GABA and Melatonin work synergistically to safely and effectively help one go to sleep and to help one resume sleep patterns.

L-Tryptophan is an essential amino acid that aids in protein synthesis and is a precursor to many compounds. Specifically, it is a precursor to the neurotransmitter serotonin (which causes sleepiness) and serotonin, in turn, can be broken down into melatonin.

GABA is an amino acid classified as a neurotransmitter, is abundantly present in the brain, and serves as a balancer between excitation and inhibition. GABA stimulates the anterior pituitary gland, increasing the levels of Human Growth Hormone in the body. HGH has anabolic and lipotropic effects - building muscle and preventing fat. GABA participates in promoting relaxation, which allows one to sleep. Unlike many relaxants, it does not cause drowsiness, just eases anxiety. As a natural stress-reducer, GABA supplements may help support pain reduction. They may also lessen pain-related nerve impulses. For the brain and neural health, GABA appears to inhibit nerve cells in the brain from firing haphazardly.

Melatonin is a natural substance secreted by the pineal gland. Melatonin is recognized as a key element in regulating the body's day/night metabolic rates. Its secretion is synchronized with our biological clock which dictates the daily changes upon the body's metabolic activity, our circadian rhythms. One of its most popular use is to help alleviate jet lag.

Melatonin is also an excellent antioxidant: a potent, free-radical scavenger. It also reduces blood platelet aggregation and thus provides an aspirin type of protective effect on the coronaries, improving blood pressure levels. Another crucial role of Melatonin is in its maintenance of the immune system

Somniphan is a safe and effective sleep aid that is suggested for individuals who:

  • Experience occasional or chronic sleeplessness.
  • Experience frequent night wakings (due to stress). It may also be helpful for men who experience frequent night wakings due to prostate overactivity (e.g. frequent nighttime urination).
  • Experience mood swings or negative outlook and as a consequence have trouble sleeping.

Suggested Usage

As a dietary supplement, take 1-2 capsules daily, half an hour (30 min) before bedtime, or as recommended by your healthcare practitioner.

If you find that upon wakening you are sluggish or drowsy, reduce dosage to 1 capsule daily.
