Consider a multivitamin

If your loss of appetite is keeping you from eating well for more than a few days, you might consider asking your doctor about taking a multivitamin. Cancer treatments and other medications can interact with nutritional supplements, so discuss it with your doctor first.

Check the label and look for a multivitamin that doesn't give you more than 100% of the Daily Value of all the vitamins and minerals.

Keep in mind, though, that if you're eating or drinking nutritional supplements, such as bars, cookies, smoothies and other products that are fortified with additional vitamins and minerals, you may not need a multivitamin or additional supplements.
