Increasing powers of concentration

Twenty-four 14yr old schoolgirls treated with Bio-Strath® for 10 weeks experienced significant improvement in arithmetic & language ability attributed to improved concentration, endurance and memory and simultaneously benefited from significantly less absences from school due to illness; i.e. 1.9 lessons periods lost in those on Bio-Strath® vs 8.6 in those not.
