Research shows that IQ is a strong predictor of student academic performannce. Previous studies have found that increasing the intake of vitamins and minerals improves non-verbal intelligence. The purpose of this study was to measure the effect of an herbal food supplement, Maharishi Ayurveda Student Rasayana (MA-SR), on non-verbal intelligence.
The 5-month study consisted of 34 third-grade students who were randomly assigned to either an experimental group or a placebo group. The MA-SR group exhibited a 9.83 point increase in IQ compared to 4.88 points for the placebo group.
Analysis of the data indicated that a significant proportion of students in the MA-SR group (78%) compared to that of the placebo group (50%) showed an improvement in IQ which exceeded that of the test-retest effect. Additional statistical analysis further indicated that taking MA-SR improves IQ.
