Americans spend billions of dollars on supplements each year, and roughly 1 in 3 adults report taking a multivitamin. But there is a debate about whether this helps promote good health.
A team of researchers wanted to assess how a daily multivitamin may influence cognitive aging and memory. They tracked about 3,500 older adults who were enrolled in a randomized controlled trial. One group of participants took a placebo, and another group took a Silver Centrum multivitamin, for three years. The participants also took tests, administered online, to evaluate memory.
