As I mentioned previously, dietary supplements are not regulated by the Food and Drug Administration (FDA) and there are no strict labeling standards. In addition, there are hundreds of brands available for any given category . So how do you choose a supplement that is safe, free of contaminants and has the ingredients the label indicates?
First, discuss any supplement needs with your healthcare provider and pharmacist. They can best guide you regarding the need for any supplement and monitor for any side effects or interactions with your current medications. Ask for their suggestions on brands they trust and would recommend. They have years of experience and their own expertise on which brands are safe and effective.
