A dry yeast composition which includes 5-adenosyl-L-methionine and a thickener and has excellent storage stability. A thickener is added to a yeast cell concentrate obtained by culturing yeast which has SAMe-producing ability and collecting the cells, and the resultant mixture is dried. Thus, a dry yeast containing a high concentration of 5-adenosyl-L-methionine which has excellent storage stability and excellent bioabsorbability can be easily and profitably produced. It is hence possible to supply a market with a dry yeast composition that contains a high concentration of 5-adenosyl-L-methionine, which is useful as a water-soluble physiologically active substance, and that has excellent storage stability and bioabsorbability.
