Have taken for years still effective in helping me sleep.
These are 200 mcg which is a fraction of a 1 mg tablet. They work great. When it comes to melatonin more is not better, less is better. I love the minty taste & take one nightly. If I wake up during the night I sometimes have another.<br />I love that I don't wake up in the morning feeling sluggish or drugged, I feel like I had a regular nights rest. If you take one & realize you have to stay up it won't make you feel sleepy or groggy, you can get up without sleeping and feel normal.  Your body already produces the harmone melatonin to help you sleep, I think this just gives it a little push in getting started.
