You are right. The fat can come from anywhere in your diet, it doesn't have to be in the milk to help with the vitamin absorption. Once everything is mixed in your stomach (or your intestines), it doesn't matter where the fat has come from. It just needs to be there to help the fat-soluble stuff get across the border of your intestines which is water-based. Bile from your gall bladder also helps with this, but you don't have to do anything to make that happen (assuming you have a gall bladder!).
