Q: What is the best time of day to take my multi-vitamin?
– Dave in Santa Fe, New Mexico

A: It doesn’t matter when you take your supplement, as long as you take it with food to maximize absorption. (Women also don’t want to take a multi-supplement at the same meal that they drink tea or coffee, since tannins in these beverages will block iron absorption.) Studies have not proven that taking your supplement at one time of day or another or even that taking a single nutrient, such as calcium, at a particular time of day has any effect on its absorption and use in the body. -Elizabeth Somer
