Methods of preparing a nutritional product which contain a lipophilic nutrient are disclosed. The nutritional product is made using a fortifying powder containing the lipophilic nutrient, a monoglyceride and diglyceride (“MDG”) oil, a phospholipid, and a carrier. The fortifying powder enhances the digestive absorption of the lipophilic nutrient when the nutritional product is consumed. The fortifying powder simplifies the process of manufacturing the nutritional product, as the fortifying powder can be added at a suitable stage of the process with other powdered ingredients. The fortifying powder may be manufactured in bulk and stored for later use, thereby improving manufacturing efficiencies. The fortifying powder and methods of preparing the fortifying powder are also presented.
