You faithfully take your vitamins.

But are other vitamins or body conditions causing your vitamins to turn into very expensive urine?

For instance, A, D, E, and K are fat-soluble vitamins, which mean you need to consume fats in order to readily absorb them. If you’re on fat-free diets, this poses a problem.

Calcium absorbs at a higher rate with many other vitamins, such as magnesium and vitamin D.

But it also has negative interactions with others:

Calcium competes with iron in normal doses, and the two nutrients should not be taken at the same time. Fluoride, phosphorus, manganese and zinc absorption also decline when these minerals are taken together with calcium.

And lastly, Vitamin C can boost your absorption of other vitamins, such as chromium and iron.

When you start a vitamin supplement regimen, make sure your vitamins work together and don’t compete. Taking too much of any one vitamin is a recipe for health consequences.
