What cancels out or decreases Vitamin E in our bodies?

Question

This question may sound a bit random, but I was doing some research on the internet for a story I'm writing. I really need to know if there is anyway to decrease Vitamin E in one's body. For example, I know that taking a Calcium pill with "cancel out" a Vitamin B pill.

Answer 1

Im not quite sure besides St.johns wort as a matter of fact st johns wort cancels almost every medication within your body due to a chemical in the liver.

Answer 2

Vitamin C can counteract the effect of Vitamin E...Whereas Vitamin E can counteract the effect of Vitamin A.

It's worth noting, if you don't already know that vitamins A, D, E, and K can be toxic because they are fat soluble vitamins. If you overdose on any of those, the levels of the other three are significantly decreased.  

Vitamin B actually increases the excretion of calcium...

Hope this helps :)
