I am quite satisfied with this supplement. by FNU Vishal on Aug 5, 2020 (Verified Purchase)

It worked for me by Y.P.N. on Apr 12, 2020 (Verified Purchase)

Natural vegetarian dietary supplement that uses herbal extracts instead of synthetic drugs and the bottom line is that it worked for me. The product is in easy to take capsule form with no taste/aftertaste. And they have great customer service too.*

It really works! by Brandy Magruder on Mar 16, 2020 (Verified Purchase)

I loved that it actually works. Three times a day is hard for me, but the alternative is many medications that make me drowsy. I do get a little acid reflux. So, I eat a little bit like a piece of bread with peanut butter. I will eat half take the pill then eat the other half and I'm good. If I could just remember to take them with my meals I'd be set. Overall, great product for price. The capsules are larger than expected, but that's ok with me as I don't have trouble taking them. I imagine you could open the capsule and put it in putting or apple sauce to take though.*
