    Abstract: A method of obtaining an exosome-enriched product comprises providing a whey-containing bovine milk fraction, conducting a first centrifugation of the whey-containing bovine milk fraction to obtain a whey middle fraction, conducting a second centrifugation of the whey middle fraction at an increased speed to obtain a concentrated whey fraction, filtering the concentrated whey fraction to obtain a filtered whey fraction, and conducting a third centrifugation of the filtered whey fraction at a further increased speed to obtain an exosome-enriched product. The exosome-enriched product comprises intact exosomes and less than 5 wt % casein based on the total weight of protein in the exosome-enriched product. Nutritional compositions comprise protein, carbohydrate, and/or fat, and exosomes provided by addition of the exosome-enriched product. A method of improving insulin sensitivity in a subject comprises administering a nutritional composition comprising the exosome-enriched product.
