Don't OD on Vitamin D

Written by 

In fact, if you're taking a vitamin D supplement, chances are that you're already taking more than you should.

While conventional wisdom says that taking an excess of vitamins isn't bad for you -- unless you go really sky high with the dosing -- excess amounts of vitamin D can reportedly produce negative effects when taken in high doses. And the effects can creep up on you.

One concern? Obesity.

The key to understanding the harmful effects of too much vitamin D lies in the fact that it is a fat soluble substance. So, if you take more than you should, it won't be naturally eliminated from your body through urination, the way that water soluble vitamins are.

As a result, says Popular Science, "Instead of being carried out in your body's wastewater, the vitamin will cling to your body fat for later use—which can compound the effects of daily overdosing."

Making matters worse, it's easy to OD on vitamin D, since taking a capsule or two a day doesn't seem like it'd do much harm. But it can; 2 capsules of vitamin D at 2,000 IU each add up to the daily limit of 4,000 IU. Since you're probably getting doses of D from other sources, including sunshine (which stimulates the body to make it), that puts you over the limit and into D-storing/accumulating mode.

But would taking a smaller dose, just to be on the safe side, be a bad thing?

PopSci says it's much the same as any vitamin-taking issue: You don't likely need them unless you have a vitamin deficiency.

Instead, the magazine continues, "...unless you’re getting almost no vitamin D, you’re probably fine."
