There also two important claims authorised for DHA (dodecahexanoic acid), a component of fish oil which can also be manufactured by fermentation. They are:-

  • ‘contributes to the maintenance of normal brain function (general population)’
  • ‘maternal intake (of DHA) contributes to normal brain development of the foetus and breastfed infants’.

A claim may be made for a single nutrient or several nutrients.

The EU Health Claims Register is dynamic in nature and should be checked for updates
