DHA is one of the fatty acids incorporated into the cell membranes of the brain and nervous system. The body cannot produce enough DHA on its own — levels are built up through what we obtain from our diet, and oily fish is the primary source.
That is why EFSA, the EU’s food safety authority, has approved the claim that DHA contributes to the maintenance of normal brain function.
The effect is achieved with a daily intake of at least 250 mg of DHA. This is an effect that has been scientifically reviewed and approved — not a marketing claim.
If your child rarely eats oily fish, a pure supplement is an easy way to ensure an adequate intake.
