A: As with any type of website or advertisement, it is wise to remember that there may be sponsors behind the media trying to convince viewers or readers to buy their products. Seeing something in writing—whether in a magazine, online, or in a glossy brochure -- does not alone give it validity. Pharmaceutical companies as many other businesses employ professional communications firms to create slick advertisements for them, some of which look like news stories or scientific articles rather than paid promotions. Therefore, if you see a product or concept that interests you, make an effort to research it thoroughly.

Seek reputable sources to consult when conducting your research. Ask your doctor or a nurse about health-related products or medical issues and contact established, respected organizations such as the National Institutes of Health; the American Heart Association; the American Diabetes Association and other charities known to you and that you deem credible; and Consumers Union, publisher of Consumer Reports, which you’ll probably find at your local library.
