7-Dehydrocholesterol (7-DHC) is a zoosterol that functions in the serum as a cholesterol precursor, and is photochemically converted to vitamin D 3 in the skin, therefore functioning as provitamin-D 3. The presence of this compound in human skin enables humans to manufacture vitamin D 3 (cholecalciferol).
While some studies have found that vitamin D 3 raises 25(OH)D blood levels faster and remains active in the body longer, [44] [45] others contend that vitamin D 2 sources are equally bioavailable and effective for raising and sustaining 25(OH)D. [46] [47] If digestive disorders compromise absorption, then intramuscular injection of up to ...

While Marco Polo wrote of Mongolian Tatar troops in the time of Kublai Khan who carried sun-dried skimmed milk as "a kind of paste", [3] the first modern production process for dried milk was invented by the Russian doctor Osip Krichevsky in 1802.

An example is skim milk that has had the fat removed, and then had vitamin A and vitamin D added back. Vitamins A and D are both fat-soluble and non-water-soluble, so a person consuming skim milk without fats may not be able to absorb as much of these vitamins as one would be able to absorb from drinking whole milk.
The vitamers of a given vitamin perform the functions of that vitamin and prevent symptoms of deficiency of that vitamin. Vitamins are those essential organic molecules that are not classified as amino acids or fatty acids. They commonly function as enzymatic cofactors, metabolic regulators or antioxidants.
Animal-source foods are a diverse group of foods that are rich in bioavailable nutrients including calcium, iron, zinc, vitamins B12, vitamin D, choline, DHA, and EPA. [11] Animal-source and plant-based foods have complimentary nutrient profiles and balanced diets containing both reduce the risk of nutritional deficiencies. [ 11 ]
While MFGM makes up only an estimated 2% to 6% of the total milk fat globule, [1] it is an especially rich phospholipid source, accounting for the majority of total milk phospholipids. [ 10 ] [ 11 ] In contrast, the inner core of the milk fat globule is composed predominantly of triacylglycerols.
