Finding a sleep aid can be a Goldilocks experience -- sometimes it's necessary to try a few before you find one that's just right. For me, L-Tryptophan is just right, and it has been for years.
Unlike a "sleep aid," which more or less puts you to sleep and keeps you asleep, L-Tryptophan lets you fall asleep and stay asleep. For me, that's an important difference! L-tryptophan is an essential amino acid, which means the body can't make it, so it has to be consumed through foods or supplements. It can be helpful for persons (like me) who have difficulty "turning off" to sleep. It can help generally with feeling anxious or wound-up, and when you're more relaxed you breathe more easily, which means you relax more, and so forth. Ultimately, tryptophan converts to serotonin, a neurotransmitter that helps with mood and sleep.
You might be wondering why one would take L-tryptophan, with its roundabout way of producing serotonin, rather than just take melatonin, which is one of the better-known sleep-assisting supplements. Well, some folks -- like me -- get nightmares and night terrors on melatonin. I've tried several times over the years to take it, each time with the result that I have horrifying night terrors. I've never had a negative response to L-tryptophan.
I've also used NOW products for years. The NOW brand meets my requirements for any supplement that I consume. It's manufactured in a cGMP (Current Good Manufacturing Practices) facility. In fact, it was one of the first manufacturers to pursue GMP certification (which means, consequently, that its facility is FDA-approved). And they do extensive product quality testing.
So, having used this product for years, I can recommend the NOW Foods L-tryptophan without hesitation. As with any supplement that you're taking for the first time, it's important to do your homework to ensure that what you're ordering, and from whom, seems like a good match for whatever symptom you hope to address. In this case, from long experience, I can say that I've found L-tryptophan to be consistently helpful for sleeping without side effects.
