Spirulina is an algae that grow in fresh and sea water and itself known to the human community with its unique Neutraceuticals properties, generally produced from the species named Arthrospira platensis, and Arthrospira maxima. Arthrospira species were cultivated throughout the world to fulfil the need of human dietary supplementation. An experimental study was planned to know the effect of spirulina supplementation on serum biochemical profile of Wistar albino rats as model study. Test results clearly denoted that diet planned with spirulina fed rats showed better serobiochemical profile when compared with stock diet and rice based diet.  The protein and albumin values were significantly higher in spirulina fed rats. Feed consumption rate is very low in spirulina diet but gained more weight when compared to stock and rice diets, this might be due to high biological value protein in spirulina.
