Good tasting berberine!
These are great berberine pills. They help combat hunger and food noises. Take them any time of day. The taste is pleasant as opposed to other berberine pills. Good product.

Increases wellness
Gentle support of boold sugar. It's a good combination of herbs that affect different body functions while boosting wellness naturally. The product is probably safe unless someone allergic to one of the ingredients. It has good health affects after 6 to 10 weeks

Works for Appetite!
I honestly expected this to be like any other product that works for everyone else, except me. Well, it actually curbs my appetite. I don't notice a flavor. I do take Raspberry Keytones on lunch as well. The problem is, I actually need to remind myself to eat. I haven't lost any weight from it, but I've only been on it a week. I'm dealing with a back injury and the meds they put me on made me gain so much weight, especially since i can't go to the gym currently. Since I started taking this, I stopped gaining weight , so that's huge for me. It's definitely worth the money, if you're having issues like me!
