More and more, physicians and nutritional experts are turning to supplements of naturally-occurring vitamins and minerals in food rather than relying solely upon prescription medication that, for some patients, may be unaffordable and/or difficult to use because of unwanted side effects. Chromium supplements are a perfect example of this trend; they are available without a prescription and very affordable when compared to prescription medications. However, before using a chromium supplement, be sure to consult your physician; it is possible that chromium may cause serious side effects when combined with some types of prescription medication.
