Obesity has been related with disordered iron homeostasis and cause anemia.The present study was carried out to investigate the effect of spirulina platensis (Dried green algae) on hematological parameters and its role on body weight of obese anemic rats. The current study was performed on 35 adult male rats. Rats (n=35) were divided into two main groups. The first group (7rats) was fed on basal diet as negative control group.The second group (28 rats)were fed on high fat diet, deficient in iron and adding 10 g tannic acid/kg diet to cause obese anemic model then were divided into 4 subgroups, the 1st subgroupwas fed on high fat diet and kept as a control positivegroup while, other subgroups 3, 4 and 5 were fed on high fat diet and supplemented with 2.5%, 5%, and 7%, dried spirulina, respectively. Supplementation with dried spirulinaat the tested levels might help overcome (P<0.05)obesity due to the improvement in hematocrit, hemoglobin, red blood cells and platelets of the treated groups. Moreover, significant (P<0.05) improvement in liver functions and lipid profile of the tested rats were observed. In conclusion, data suggested that spirulina is useful for obese anemic patients
