The present study was designed to investigate the effect of supplementation of spray dried Spirulina powder on blood haemoglobin levels in young anaemic girls of ages ranging from 18-22 years. They were screened for their anthropometric measurements, clinical signs and symptoms related to anaemia and blood haemoglobin levels. Blood haemoglobin levels less than 12 g/dl were used to find the prevalence of anaemia. Diets of 20 anaemic girls were supplemented with 5 g of spray dried Spirulina powder daily for a period of 30 days and the blood haemoglobin levels were estimated at the end of the study period. Supplementation was carried out in two forms - in the form of syrup and in the form of parathas. The prevalence of anaemia in the girls was 28.2%. The diets of these girls revealed deficit intakes of calories and iron, while the intakes of phytates and oxalates were found to be high. A mean increase of 1.17 g/dl i.e., 10.33% in the blood haemoglobin levels was seen in all the anaemic subjects after supplementing Spirulina tor 30 days. A mean increase in the blood haemoglobin levels by 1.32 g/dl i.e., 11.65% was seen in those girls supplemented with Spirulina in the form of syrup, while a mean increase of 0.88 g/dl i.e., 7.72% was seen in those supplemented with Spirulina as parathas. This increase could be due to the absence of inhibitors of fron absorption - oxalates and phytates in the syrup, which were otherwise present in the parathas. It was concluded that supplementation of Spirulina had beneficial effect on the haemoglobin levels and could be effectively used to combat iron deficiency anaemia.
