Abstract: The present invention is a multifunctional nutrient supplement and a process for creating the supplement. The supplement comprises a mixture of lecithin, ginkgo biloba and wheat germ oil. The supplement is made with a five step formation process. The first step of the process uses CO2 supercritical extraction to remove cholesterol, glyceride and fatty acids from an egg yolk. Wheat germ oil is then obtained from dried wheat germ using CO2 supercritical extraction. Gingko biloba is then removed from ginkgo leaves using CO2 supercritical extraction. The egg yolk/lecithin from the first extraction is then combined with the wheat germ oil from the second extraction. Ethanol is then added to the mixture of lecithin and wheat germ oil and low temperature vacuum distilled to create a lecithin and wheat germ oil mixture. The ginkgo biloba extract is then added to the lecithin/wheat germ oil mixture to create the nutrient supplement.
