Compositions for increasing red blood cell levels or treatment of anemia comprising erythropoietin receptor activators and a variant Activin RIIB (ActRIIB) polypeptide having a leucine residue replaced by a acidic amino acid residue, where the variant ActRIIB polypeptide has a reduced affinity for activin B and may be called a GDF trap. Methods for the use of these compositions.
