Not all vitamins work well together… In fact, experts are warning that certain combinations should NEVER be mixed

This matters especially for people who take supplements for low iron levels while also trying to support bone health with calcium. Experts say both nutrients can still be taken safely, but they should be spaced apart instead of swallowed together.

Separating the supplements by several hours may help the body absorb each nutrient more effectively.

People who take multiple daily supplements may benefit from reviewing labels carefully to avoid accidentally combining minerals that work against each other.
