Multivitamins and supplements are a billion-dollar industry, with global vitamin industry sales last year totaling more than $23 billion. But are these supplements worth the price? With an estimated 40% of Americans taking a multivitamin daily, the perceived benefit often outweighs the actual advantage. Here’s the potential good – and not so good – effects of the top five most common supplements:

Remember, supplements are not intended to treat, cure or prevent any disease. In fact, it is very important to discuss all supplement use with your doctor or pharmacist, since:
Supplements have the potential to reduce the effectiveness of some medications, and
Supplements have the potential to increase the toxicity of other medications.
Discussing supplements with your health care provider is also a great way to uncover health problems that might otherwise have been left unaddressed; for example, asking your doctor about a supplement to alleviate one problem may uncover the true source of the ailment instead of treating just the symptom.
Before considering adding any supplement to your healthy habits, be sure you are doing all you can to live a long and healthy life. This includes eating a healthy diet, exercising regularly, getting enough sleep, maintaining a social network and, of course, following the recommendations of your health care professionals.
