LA CROSSE, Wis. (WEAU) -- If you take multivitamins some researchers say you may want to reconsider.
Three studies from the Annals of Internal Medicine said vitamin and mineral supplements don’t prevent disease or its progression.
One study shows supplements don’t decrease the risk of death, heart disease or cancer.
A second study says multivitamins don’t have any effect on cognitive performance or memory in adults.
The third found multivitamins don’t prevent a second heart attack.
Researchers also say in some cases supplements could harm you.
Registered dietitian Marisa Pruitt said taking a multivitamin or mineral probably won’t hurt you, but it’s not a substitute.
“Our body doesn’t utilize a supplement the way it does actual food sources of those vitamins and minerals. So we always want to turn to our food first,” said Pruitt.
Pruitt said if you’re going to take a supplement, it shouldn’t contain more than 100% of all vitamins and minerals.
She ones containing mega doses or extra stuff probably mean you paying extra money for something that isn’t really a health benefit.
