Interactions with Vitamin D
by: Kerri Knox, RN- The Immune Queen

Answer:

Hi Harry,

What a great question. The only other vitamin that has an interaction with Vitamin D is Vitamin A. Bother compete for the SAME receptor sites and therefore can crowd each other out.

Particularly, it seems, Vitamin A crowds out Vitamin D. Not to say that Vitamin A is 'bad', we need a certain amount of it, but in moderate doses.


If we get our Vitamin D through our food, then we need to have a certain amount of fat with it due to the fact that it is a fat soluble vitamin. But not much fat is required to absorb it.


Conversely, Vitamin D is absolutely essential for the absorption of Calcium. When sufficient Vitamin D is present, it can increase absorption of calcium up to Twenty Times!

Remember, too, that Vitamin D is not really a 'Vitamin', but is a HORMONE! And it is designed to be synthesized through our skin. And in order to be synthesized, it absolutely requires cholesterol to be present in the skin.


While there have been no studies done on it, it is a good question for further studies as to whether our new lower and lower guidelines for cholesterol Could affect the synthesis of Vitamin D from sunlight.


So, while it's ALWAYS a good idea to get a sufficient amount of All of the Vitamins, Vitamin D is a bit of an island unto itself that it really doesn't require any other vitamins in order to be synthesized.
