Ask Tufts Experts May 2015 Issue

Q. I take a morning calcium and vitamin D as well as my multivitamin with breakfast. Am I impeding absorption of any of these vitamins and minerals by taking them together? With the multivitamin, could I be getting too much calcium?

A. Bess Dawson-Hughes, MD, director of Tufts’ HNRCA Bone Metabolism Laboratory, answers: “I know of no downside to taking the supplements together. The calcium content of most multivitamins is generally less than 200 milligrams, so multivitamins don’t make much contribution to total calcium intake. Total calcium intake for adults (from food and supplement sources) should be 1,000 to 1,200 milligrams per day.”

I am severely lactose intolerant and recently gave up all fish because of toxic blood levels of mercury associated with EMG documented neuropathy and a host of issues that are resolving off fish. I have home made almond milk daily on my oatmeal with berries and homemade granola including walnuts, raisins, as well as oats and the meal from the filtered almond milk.. I eat lots of beans and vegetables but no meat as I am concerned about animal cruelty, the environment, and for religious reasons(Buddhist). I do take B12 but wonder If I can get enough calcium with this type of diet? I live in Costa Rica and use sun blocks and a rash guard when surfing, running and playing tennis though I do get quite tan in this tropical region. I eat a ton of fruits and vegetables , tofu, and brown rice, to maintain my weight 180 lbs at 5 feet 11 inches as a man. Supplement calcium??
