NOW Foods L-Tryptophan
220 mg 60 Capsules
Source of an essential amino acid for the maintenance of good health.

L-Tryptophan is a large neutral amino acid essential to human metabolism because it is the metabolic precursor of serotonin (a neurotransmitter), melatonin (a neurohormone), and niacin (vitamin B3) which assist in the regulation of sleep, positive mood and immune function. L-Tryptophan is not synthesized by the body and must be obtained from the diet. As a component of dietary protein, tryptophan is particularly plentiful in chocolate, oats, bananas, dried dates, milk, cottage cheese, meat, fish, turkey, and peanuts.

Ideal for those wishing to boost serotonin levels.

Annie: a few months ago

It is difficult to evaluate the quality of that kind of product, but nevertheless, using tryptophan with a complex B and omega 3 every day for a month, I noticed an improvement in my mood.

Does not work for me

Trevor: more than a year ago

love this

Bonnie: more than a year ago

I found NOW products are excellent quality and price and these tryptophan supplements are no exception. I take these nightly as tryptophan helps your brain naturally release melatonin so that you experience a most deep & refreshing sleep. Tryptophan is a pre-cursor to 5HTP which releases serotonin which is an added benefit. Women in their menopausal stage will experience some relief from middle of the night insomnia.

Tryptophan is a pre-cursor to melatonin meaning it helps our body produce that "chemical" in our brain naturally to produce deep and satisfying sleep. For women who are entering the hormonally challenging peri-menopausal stage of life, they could really benefit from a nightly dose of this product. I take it nightly with no groggy morning issues or other side effects. It works wonders!
