Now Foods, L-Tryptophan Powder, 2 oz (57 g)
By Now Foods26 Reviews
The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.

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.

iHerb Customer Reviews
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.
