Are vitamins worth taking?

Maybe: I advise my patients on vitamins by using this analogy: vitamins are like your car insurance; you hope you never need to use it but it's nice to have when you do need it. If one always eats a variety of foods, 5 servings of fruits and vegetables every day, low saturated fats and high fiber, then one probably does not need vitamins. That being said, i recommend one multivitamin daily.

Yes: However, the quality of the vitamin is very important, as well as what it is in it. The most common vitamin deficiency in vitamin d deficiency, which can be diagnosed by a blood test. Persons with asthma and low vitamin d are at higher risk for hospitalization. The most common trace mineral deficiencies are zinc and magnesium.
