meet the daily requirements for any of the nutrients. Supplementation with Spirulina led to an increase in the intake of a few nutrients. The protein intakes increased by the 2.4% and the iron intake increased from a mean of 8.72 mg/day to 9.32 mg/day.

Effect of Spirulina supplementation on the mean hemoglobin levels is depicted in Table 4.17. While the initial hemoglobin level was similar in the two groups, at the end of the intervention period, the subjects in the experimental group had significant higher mean hemoglobin levels as compared to the control group, when the data were analyzed for two categories—all subjects and anemic subjects.

The Spirulina-supplemented group showed a significant increase in mean hemoglobin levels from an initial of 10.20 g/dL to a final of 11.30 g/dL. As against this, the control group showed a decrease from an initial 10.47 g/dL to 10.15 g/dL by the end of the study period. This change in hemoglobin levels from initial to final was statistically significant in both the groups. It can be seen that while the subjects who were anemic (<11 g/dL) initially and were supplemented showed an increase in mean hemoglobin levels form 9.58 g/dL to 11.14 g/dL, those who had normal hemoglobin levels to start with, maintained their hemoglobin levels. In contrast to this in the control group there was a significant decrease in hemoglobin levels in subjects with initially normal hemoglobin levels. The experimental group showed a rise in hemoglobin levels, which was significantly different from the drop seen in the control
