I've been taking 400 IU of Vitamin D3 every other day or so this
winter. The only catch is that I've been taking them in
microemulsified drops. One drop is supposedly worth 400 IU of
microemulsified Vitamin D. So, like I said, every other day or so,
I'll take a drop, along with some food. Does anyone know of any
research that shows how emulsification affects the absorbption of
Vitamin D? What I'm looking for is perhaps what has been found to be
the average equivalent non-emulsified dose for, say, 400 IU of
microemulsified Vitamin D. E.g., would the answer be 400 IU
microemulsified = 4000 IU non-emulsified ?

Anyway thanks...

It depends on the state of health of the person
taking the supplement. If the person has
cystic fibrosis or is missing a gallbladdder, the
emulsified vitamin maybe the better choice.

In a healthy persons eating some fat with the non-emulsified
vitamin D, the absorption is likely pretty good.
It would likely be a good idea to eat some fat
with emulsified vitamin D capsule also.

since lipids are emulsified during digestion as well, and since vitamin d is
fat soluable it should not make a big difference if it's pre-emulsified or
if your body emulsifies it as long as you don't have any disorders
concerning generation of bile acids.

At least in the case of vitamin E and CoQ-10 taking these
agents with fatty foods increases uptake. Indeed, as I recall
A and D aren't as well absorbed for nonfat fortified milk
as from skim or whole milk.
