Since vitamin D is a fat-soluble vitamin, can we absorb it from skim milk?
Although it is true that we need some fat to absorb vitamin D from our digestive system, the fat does not have to come from the same food. As long as there is a small amount of fat present in our digestive system, that appears to be enough. Studies that have looked at the absorption of vitamin D from skim milk and juice, which is also fat-free, show that the absorption of this vitamin is undeterred by the lack of fat in these liquids.
