The present invention relates to microcapsules and to methods for them. The microcapsules comprise a polymeric coating that is at least partly crosslinked with a polymeric matrix comprising a polysaccharide. In the matrix, a lipid and an active agent or a prodrug or salt thereof are embedded, the lipid preferably having a melting point of at least 30° C. The microcapsules can be used as a medicament, dietary supplement or food additive, the microcapsules comprising a polymeric coating that is at least partly crosslinked with a polymeric matrix comprising a polysaccharide. As above, a lipid and an active agent or a prodrug or salt thereof are embedded in the matrix, with the lipid preferably having a melting point of at least 30° C. Methods for treating diarrhea or preventing colon cancer comprising administering such microcapsules are also disclosed.
