Safe Weight Loss Pills

I wonder if there is really such a thing as safe weight loss pills in the market, safe as in a pill that does not cause any negative side effects to the body. If you have taken a weight loss pill and have not suffered from any type of ill side effects whatsoever, I’d love to hear your story. I have never taken any weight loss pills and the nearest to a weight loss product I’d taken was some kind of tea that helped me move all the sludge out from my guts!
