In my day-to-day practice, I see many patients who are extremely ill. It’s not uncommon for at least one patient a week to come into my office with shopping bags full of different products purchased from infomercials, Amazon, Costco, or a local drug store. Seeing this happen over-and-over again is concerning, since many products really aren’t what they claim to be. Because vitamins, herbs, and natural supplements aren’t regulated by the Food and Drug Administration (FDA), many products that are available over-the-counter (OTC) are poor quality and in some cases, can even be more harmful than helpful. In addition, many labels have ambiguous instructions concerning administration. It’s not uncommon to see something like, “take 1-2 capsules, 2-3 times per day, or as instructed by your health care provider.” Huh? What does that mean?
