Dietary supplement safety

Taking large doses of supplements has not proven to be effective. In fact, it can be toxic. The National Institutes of Health does not advise taking vitamins or nutrients over the recommended daily allowances (RDAs).

Always check with your healthcare provider before taking any supplements. Some may interfere with prescription medicines you take. Tell your provider what supplements you take and why. They can make sure your health concerns can be addressed.
