This tool adds up the nutrients in your supplements and compares them with NIH reference values for healthy adults aged 19 and over. Food adds to these totals except where noted, so a supplement total close to the upper limit is worth a second look. It is not medical advice: talk to your doctor or pharmacist before changing what you take, especially if you are pregnant, take medication, or have a health condition.
