VITAMINS AND MINERALS IMPROVE LEARNING AND MEMORY IN 'NORMAL' SCHOOL CHILDREN
In two parallel studies (randomised, double-blind), a total of 780 'normal' school aged Indonesian and Australian children were given either a combination of vitamins and minerals, a supplement of omega-3 essential fats EPA and DHA, or the vitamins and minerals with the omega-3 fats, or a placebo on 6 days a week for 12 months. At the start of the trial, the children were tested for blood levels of all of these nutrients, all of which significantly improved when they were retested after 12 months. The Australian children on the vitamins and minerals had significant improvement in tests of verbal learning and memory as did the Indonesian girls.
