Tryptophan is an essential amino acid that is necessary for the productions of vitamin B3 and used by the brain to produce serotonin, a necessary neurotransmitter that transfers nerve impulses from one cell to another and is responsible for normal sleep. Consequently, tryptophan helps to combat depression and insomnia and to stabilize moods.
It helps to control hyperactivity in children, alleviates stress, is good for the heart, aids in weight control by reducing appetite and enhances the release of growth hormone. It is good for migraine headaches, and may reduce some of the effects of nicotine.
A sufficient amount of vitamin B6 is necessary for the formation of this essential amino acid, which in turn, is required for the formation of serotonin. A lack of tryptophan and magnesium may contribute to coronary artery spasms.
The best dietary sources of tryptophan include brown rice, cottage cheese, meat, peanuts, and soy protein.
