Helps my sleep-maintenence insomnia! So thankful!

I take two of these, ideally, one hour before bed time. It is the only natural supplement that helps my sleep-maintenence insomnia. If you don't know what that is, it is the type of insomnia that has you waking up too earlier, and it is very hard to fall back asleep. Falling asleep is easy, but its about the 4-5 hour mark that you wake up, brain turned on, and it takes a couple hours to fall back asleep from exhaustion. Then of course you have to wake up not long after you fall asleep.... There was only one pharmeceutical that helped, but it would leave me groggy for many hours after waking. With L-Tryptophan, at 1000mg per night, I wake up a little sleepy, but it goes away fast after getting up and moving. After a month or so, I can even move to taking this every other day, or a few times a week. But I always keep it around now. So thankful I found it. I wonder if I have an absorption problem with getting it naturally from food, or something like that. Its a low price to try it, so give it a try!

Great Dose That Works Well But Tablets are Huge

These tablets work well but are huge. It is nice to be able to take 1 tablet instead of 2. Starts to make me tired within 30 minutes.

Now's Trytophan can be trusted

This is a fine supplement from a trusted source, which has helped many of us with frequent insomnia to find a restful night's sleep. So many supplement come from sources with questionable records, including the dominant one in so many strip malls, it's refreshing to find a company willing to take responsibility for their product.

[This review was collected as part of a promotion.] I have used this for about a year. It really helps to calm you and go off to sleep quickly.

Good Price

[This review was collected as part of a promotion.] I used to take 2-4 500mg capsules or tabs before bedtime. Now it’s just as easy to take 1-2 of these 1g tabs for less $. If you have difficulty with taking tabs tho you might want to stay with the comfort of capsules.

Sleeping better already

Sleeping better already. My naturopathic physician, perhaps unlike others, is highly selective about her nutritional supplement recommendations. She was definitely right on this one !

bedtime relaxer

Really helps me fall asleep, along with melatonin, but a little large to swallow for my small throat!

Works well

The wife takes this product on a regular basis and seems very pleased with the results. When she gets down to a dozen or so caplets she always reminds me that it is time to re-order. Overall, I am very pleased that this product has been made available by Swanson's. A name that I have come to completely trust for a quality product at a fair price.

Great product.

One of these at bedtime helps keep my mood elevated and also helps me sleep. I used to take the 500mg tablet, twice a day, but it is easier, for me, to just take this at bedtime.

Didn't Like

For some reason Now's 1,000 tablet form did not work for me. I normally use Now's 500mg CAPSULES and these work great for me (as expected). It was horrible not having the effective Tryptophan in my system that I'm used to. Since many people like this product it's obvious different formulas work differently for each person. If you're new to Tyrptophan be sure to find what works for you. I've used Tyrptophan for over 5 years, and with both Swanon's and Now 500mg CAPSULES I get great results, and those effects where felt in just three days. This product fell completely flat for me even the next day.

I Sleep Better

I take 2 of these every night before bed. I had started not being able to sleep well and when I would wake up in the middle of the night I could fall back to sleep. Now I fall back to sleep easily. I make sure I am never without these!

L-Tryptophan 1000 mg by NOW

Waking up in the middle of the night---or even upon waking up near morning---I nearly always can quickly return to sleep with just one 1000 mg. tablet and have used the NOW brand for years.
