 According to one definition, the word “supplement” means “something added to complete a thing, to extend or strengthen the whole.”

 Supplements can be very beneficial But you must be careful because, like any drug, all supplements pose potential risks.  __36___ 

__37___ Many, if not all, supplements have the potential to interact with prescription or over-the-counter drugs, cause harmful side effects if taken inappropriately, or even make existing medical conditions worse. __38__In a  study of University of Michigan one-third of the patients taking supplements were using ones that could interact with their heart medications. Be especially cautious if you’re taking the blood-thinning medication like aspirin, many supplements, such as garlic, vitamin E and fish oil, also have blood-thinning properties, and the combined effect could lead to dangerous bleeding.

 Also, the label may say “natural” but that doesn’t mean the supplements are any safer than medicinal drugs. They still include chemicals that have a bad impact on your body; that’s why they work.

___39___ If you are pregnant, be doubly sure to check with your doctor before taking any supplements.

In the next few years you’re bound to hear more and more about natural alternatives for protecting the heart. But before you jump on any bandwagons, take heed: __40___ The fact is that scientists will probably never be able to duplicate the complex effects and many health benefits of foods like fruits, vegetables, and whole grains with a pill. And of course, lowering your cholesterol with supplements while eating steak and ice cream with abandon, or taking hawthorn to lower your blood pressure while doing nothing to relieve the stress caused by your nerve-racking job, won’t do your heart much good in the end.

A. No supplement is a substitute for the lifestyle changes, particularly good eating habits.

B. A supplement may be natural but that doesn’t mean taking it is completely without risk.

E. That’s why it’s critical that you tell your health care providers about any supplements you take.

F. Doctors are always right, especially when you fall ill.
