For educational purposes only
This guide is educational information about vitamins, minerals, and dietary supplements — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified doctor, pharmacist, or registered dietitian. It does not recommend any supplement or dose. Dietary supplements are not evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease. Individual needs and results vary, and more is not better — some vitamins and minerals are harmful in excess. Talk to your doctor or pharmacist before starting any supplement, especially if you are pregnant or nursing, taking medication, or before surgery, because interactions are possible. In a medical emergency, call 911.
