Arachidonic acid is one of the most abundant fatty acids in the brain, and is present in similar quantities to docosahexaenoic acid (DHA).
Among other things, arachidonic acid helps to maintain hippocampal cell membrane fluidity.
Like DHA, neurological health is reliant upon sufficient levels of arachidonic acid.
Arachidonic acid is also involved in early neurological development.
In one study funded by the US National Institute of Child Health and Human Development, infants (18 months) given supplemental arachidonic acid for 17 weeks demonstrated significant improvements in intelligence, as measured by the Mental Development Index.
In adults, the disturbed metabolism of ARA contributes to neurological disorders such as Alzheimer's disease and Bipolar disorder .
To sum up, ARA is good for our health.
