Water-soluble vitamins dissolve easily in water and, in general, are readily excreted from the body, to the degree that urinary output is a strong predictor of vitamin consumption. [47] Because they are not as readily stored, more consistent intake is important. [48] Fat-soluble vitamins are absorbed through the gastrointestinal tract with the ...
Without functional chylomicrons, certain fat-soluble vitamins such as vitamin D and vitamin E cannot be absorbed. Chylomicrons have a crucial role in fat absorption and transport, thus a deficiency in chylomicron functioning reduces available levels of dietary fats and fat-soluble vitamins. [3]
Chylomicron structure ApoA, ApoB, ApoC, ApoE (apolipoproteins); T (triacylglycerol); C (cholesterol); green (phospholipids). Chylomicrons transport lipids absorbed from the intestine to adipose, cardiac, and skeletal muscle tissue, where their triglyceride components are hydrolyzed by the activity of the lipoprotein lipase, allowing the released free fatty acids to be absorbed by the tissues.
Some nutrients can be stored – the fat-soluble vitamins – while others are required more or less continuously. Poor health can be caused by a lack of required nutrients, or for some vitamins and minerals, too much of a required nutrient. Essential nutrients cannot be synthesized by the body, and must be obtained from food.
A primary goal of abetalipoproteinemia research is to supply the fat-soluble vitamins the body lacks in the disease. Previous research considered the short-term use of intravenous infusion of vitamins A and E. The goal was to determine whether these infusions would delay or counteract the symptoms in patients. No results were posted. [24]
Since it contains fatty acid functional groups, olestra is able to dissolve lipid-soluble vitamins, such as vitamin D, vitamin E, vitamin K, and vitamin A, along with carotenoids. Fat-soluble nutrients consumed with olestra products are excreted with the undigested olestra molecules.

With few exceptions, like some vitamins from B-complex, hypervitaminosis usually occurs with the fat-soluble vitamins A and D, which are stored, respectively, in the liver and fatty tissues of the body. These vitamins build up and remain for a longer time in the body than water-soluble vitamins. [2] Conditions include: Hypervitaminosis A
