What is L Tryptophan Powder Bulk?

L tryptophan powder bulk (i.e. tryptophan) is one of eight essential amino acids (i.e. amino acids that cannot be synthesized in the human body and must be supplied by the diet).3–5 For all amino acids, including tryptophan powder, only the L isomer is used in protein synthesis6 and can pass across the blood-brain barrier.

Usage And Synthesis

L Tryptophan Powder Bulk Benefits       

1) Sleep Quality and Insomnia

L tryptophan powder bulk produces melatonin in the brain (pineal gland), the gut, the retina, and immune cells. Melatonin regulates the circadian rhythm and sleep patterns and is used as a supplement itself to help people sleep.

2) PMS

The breakdown of tryptophan powder via the kynurenine pathway is affected by the phase of the menstrual cycle, which can also indirectly affect serotonin production. After ingesting tryptophan, kynurenine was 40% higher during the luteal phase than in the follicular phase.

3) Smoking Cessation

A study of 16 people trying to quit smoking showed that tryptophan powder and a high-carbohydrate diet along with regular smoke-ceasing therapies decreased anxiety and withdrawal symptoms. People given tryptophan supplements smoked fewer cigarettes compared to placebo.

4) Depression

Many depressed patients also suffer from insomnia and other sleep-depriving conditions. Therefore, tryptophan powder’s ability to help with insomnia could aid these depressed patients.

5) Mania

In a small study of five patients with mania, l tryptophan powder bulk supplementation improved the treatment with chlorpromazine hydrochloride (CPZ) and reduced side effects.

6) Appetite Reduction

In a study of 15 healthy volunteers, those receiving L-tryptophan supplementation ate 20% fewer calories and ate more proteins than carbohydrates.
