Excellent formula
This formula is truly fantastic. I have been really getting much better sleep ever since incorporating it. Sometimes I break the pills in half. I love that. The formula is all encompassing.

Great product, great price!
I use this as a sleep aid when I need it, and have found that just a third of a tablet works perfect for me, which means this bottle will last a pretty long time- I'm very satisfied!
