I recommend that people stay as far away from such supplements as they possibly can. Supplements are not FDA regulated, and you may never know what you are actually taking. The weight loss supplements and fat burners – in my opinion – are the worst of the bunch because they are tapping into the market of the desperate. Some of the ingredients may be labeled ‘natural’ but that does not make them safe. Not to talk about the potential for supplements that come from contaminated facilities. Just go ahead and google ‘dangerous weight loss supplements’, and I hope you will lose your appetite for them.
Keep eating a healthy diet and look whether you can change your routine with interval training or other methods.
