Vitamin-B and Folic intake of Kindergarten kids in Germany is only 50-70% of the official recommendations. In studies with adults it has been found that for example providing people suffering from Alzheimer´s disease improved their mental and cognitive abilities when provided with a high intake of these vitamins.The hypothesis is, that kindergarten kids, 4-6 years of age, could also improve mentally from a recommended intake of B-vitamins and Folic Acid.

  1. screening study: The urine of 1200 kindergarten kids will be analyzed for metabolites of these vitamins, and the 250 kids with the lowest results will be invited for a randomized double blind intervention study.
  2. intervention study: Participating kids will get an one hour mental and cognitive testing before and after the intervention. The intervention will be one portion of the recommended dosage of a vitamin B complex and folic acid , given in a drink (milk, tea, etc). The assumption is, that the treatment group will perform better than the placebo group in the second test phase.
