Hi loglady!
I've been using Lipovon for a month now and I haven't noticed any side effects. As of the other effects - so far I'm very pleased. I went through the first pack and so far I've lost 8 kilograms without exercising and I'm pretty impressed.
The best i suggest you is the exercise. Any product you will use, may have any side effect and even though you want to use it just take the guidance about that product from doctor or chemist. Otherwise the exercise and healthy diet ( green veggies and fruits and nuts) are the best for the weight loss.
