Abstract: The invention relates to a formulation containing a phospholipid constituent as a physiologically active ingredient, the formulation itself being in a water-dispersible granulated form and containing a fructane constituent, in addition to the phospholipid constituent, as a formulation auxiliary agent, in a weight ratio of 5 to 70: 95 to 30. At least one representative of the series phosphatidylcholine, phosphatidylethanolamine, phosphatidylinosite, phosphatidylserine and/or the lysoforms thereof is used in a preferred formulation. Typical representatives of the fructane constituent are graminan, inulin and levan. Said formulations have a particle size of between 10 and 1 mm, can optionally contain other physiologically active ingredients, and are used as/in food supplements, special foods or functional foods.
