Be careful of diet pills.
Just because something is sold over the counter does not mean that it is safe. In studies of diet pill one leading brand had a daily dose of what is equivalent to 30 cans of soda. Such high levels of caffeine can cause insomnia, tremors, stomach problems and headache. In addition to that some pills when tested have tested out to contain very high levels of chromium a mineral that helps regulate insulin and may aid in weight loss. In some cases there was up to 42 percent more chromium listed then on the label which can cause side effects like dizziness, flushing and even kidney failure.The bottom line is to think twice before taking weight loss supplements.
