The administration is done orally by drinking 200 mL of omega-3 supplemented fruit juice daily. It has a good fruity taste, low amounts of sugar, and no fish flavour. This should facilitate treatment compliance for the children in particular compared to when omega-3 is given in capsules - the commonest choice in other studies, but less suitable for children. Compliance is important and not further jeopardized by trying to divide the fruit juice in less amounts than the whole package, but the individually prescribed dose as well as the actual amount ingested will be recorded and exact calculations used in the analysis of the study.
