Works well!

Posted by whitelotusrose on Apr 01, 2014

I like this product. I usually take it at night a couple of hours before bedtime. It keeps me calm, removes my fears & anxieties & also clears my mind of negative thoughts. I also sleep well & wake up feeling calm & I can go about during the day without feeling anxious. Since it's time release the effect lasts only until evening about 5-6pm. But I just wait a few hours before taking it again. Will continue to buy this product.

The fact that the Natrol product is of a high mg strength it is slow releasing which gives the brain a steady flow of serotonin production throughout the day.

Love Natrols 5-HTP

Posted by FilaLuvR on Dec 13, 2013

We use both the 100 and 200 mg strength time release tablets from Natrol, and cannot be happier with the results. My husband after using these for a few days thinks everyone should take them. He feels that much better. They seem to last close to 18 hours, and he can tell when they wear off, so we have decided to go with the 100mg time release ones most days just taken morning and night. It does reduce appetite, so be forewarned if that is a potential issue. He always takes the night time dose, along with Natrols time release 10 mg Melatonin, and sleeps much more soundly since adding this to his regime. His energy levels have increased at work, and he is sharing this find with everyone he knows.

to need a certificate

These products need a certificate in order to trust. For example, the U.S. Food and Drug Administration. Please attach a copy my e-mail. Thank you,

Unlike the fast disolve, this one does't make stomachaches I really like it, it replaces the use of mood drugs for me

This was recommended to me to help with weight control. I'm always trying to lose 5 lbs. and this seems to help with that.
