L-Tryptophan is an essential amino acid; therefore, it is not synthesized by the body and must be obtained from the diet. L-Tryptophan is critical for the production of serotonin and melatonin, which help to support a positive mood, healthy sleep patterns, and proper immune system function. Every lot of NOW L-Tryptophan is tested to be free of Peak E and microbial contamination.
As a dietary supplement, take one or two 1/4 level teaspoons 2 to 3 times daily on an empty stomach, with final dose at bedtime, or as directed by your physician.
Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.

I found that the product "kicks in" quicker than capsules when allowed to dissolve for a couple of minutes under the tongue before swallowing. Take with a B-50 complex and a small amount of starchy food, like a cracker--and get a great night's sleep! --Christine from Oregon
I bought both NOW and Doctor's Best powdered tryptophan, and found they work the same for me. I take about a teaspoon full at bedtime; not only do I get a great night's sleep but tryptophan helps a LOT with restless legs at night. I think that the fact that tryptophan is a precursor of melatonin is responsible for this. If I take straight melatonin it causes me to be very depressed; but the tryptophan does not. I have found all NOW products to be what they say they are and to work well.
