A metabolic study was carried out on 19 school boys and girls (age 7-13 years) to assess their vitamin B6 status. The metabolic study was divided in five different periods, basal (A), post-methionine loading (B), one (C) and two (D) week after oral vitamin B6 therapy (50 mg/day) and post-methionine. Mean cystathionine excretion (beta mol/24 h) increased significantly (p less than 0.01) at stage B compared to mean values obtained at stage A reflecting a deficit in the vitamin B6 nutriture. Vitamin B6 therapy corrected the deficiency and the utilization of administered methionine.
