L-Tryptophan is an essential amino acid important in human nutrition for the synthesis of melatonin and serotonin, hormones regulating mood and stress response. L-Tryptophan helps support relaxation, sleep, positive mood and immune function. As an essential amino acid, it is not synthesized by the body and must be obtained from the diet. NOW® L-Tryptophan is pharmaceutically pure - every lot is tested to be free of Peak E and microbial contamination.

This stuff is the best sleeping pill out there. No narcotics, just an amino acid base, so no side effects. You will not have any hangover or residual sleepiness at all. NOW products makes a fine product, and through Amazon I get it much cheaper than through a local health food store. A win win for me.

I took the advice of another reviewer and tried this with L-Theanine. I am now ambian free and sleeping great! I also focus on my breath instead of my thoughts. I awake feeling refreshed, with no more fog mind. I take 1.5 of this an hour before bed.

I'm a big fan of L-Tryptophan as a sleep aid and also as a boost for the assimilation of other amino acids (other aminos are not utilized by the body as well without the integration of L-Tryptophan as they are with it included in the diet/supplement regimen).
NOW products are always reliable, and even though the caplets are rather large, they are easy to take.

Delivered on time. It works great to have a very restful sleep. You sleep relatively quickly and you don't wake up in the middle of the night. Best results with a dose of 3000 to 5000 mg.

This supplement has proven itself over time to me and is absolutely indispensable in helping to calm my anxieties and, most importantly, lessening my tendency towards depression and negative thoughts. One of the possible side effects of L-tryptophan is blurry vision and this has affected me- a downside I can live with as it merely adds to my vision problems.

I have used tryptophan for years, and have tried many brands. This one is the worst that I have tried.

It simply works much less well than others. Some of the reviews describe using very large doses to be successful. That indicates that it is not very effective. I used the Now tryptophan capsules last year and found that I needed about 3 capsules (500 mg) to get the same effect as with 2 capsules from the better brands. In a moment of poor judgement I bought some of these tablets. They are even worse. (There have been allegations that Now tryptophan is from China and is of poorer quality. I don't know if that is true, and whether that is the reason these don't work well.)

To get tryptophan (other brands) to work well, I have found that it helps to take them with a little of something sweet to aid in the tryptophan absorption. I have a bag of raisins in my bedside table, and when I awake in the night I take two tryptophan capsules and a half-dozen or so raisins. In 20 to 30 minutes the tryptophan then kicks in and acts as a gentle sleeping aid.

The only thing I don't like about this product is paying for it. Other than that, I think it is a miracle. One of these pills combined with 3 mg of melatonin puts me right out, and I have had insomnia for 35 years. This combination works as well as prescription meds I have taken in the past.

I was once a user of Ambien and it was a crutch for me. Luckily, my boyfriend turned me on to something better (and something that won't give me amnesia) and it's Tryptophan. These capsules are smaller than some of the competition, so they are easier to swallow. I highly recommend.
