Connie’s comments: My mom has skin disorders and uses zinc oxide for most of it.
If stomach upset occurs, take zinc with a meal. Zinc also interacts negatively with several common minerals, namely calcium and iron. … Iron is best absorbed if taken on an empty stomach and should not be taken with compounds such as calcium, zinc, and vitamin E, which may interfere with proper absorption. Take your iron in the morning and your calcium+magnesium+zinc + Vit D in the evening since iron cancels calcium,magnesium and zinc absorpbtion.
