Recovery from iron deficiency in rats by the intake of recombinant yeast producing human H-ferritin

The iron sources of ferritin and ferritin-producing yeast were as effective in recovery from iron deficiency as the iron compounds of ferric citrate and ferrous ammonium sulfate. The results suggest that the iron stored in the ferritin of recombinant yeast is bioavailable, and that recombinant yeast may contribute widely as a source of iron to resolve the global problem of iron deficiency.
