My son has Down Syndrome so DHA is an important supplement for him. It was recommeded by out geneticist. DHA Deficits in DHA can damage brain biochemistry and cognitive abilities. Studies suggest it may help prevent dementia in later years and it prevents plaque build up in the brain therefore lowing the risk of stroke. In DS children it also helps with dry skin and constipation. I can't say enough good things and the fact that Nordic Naturals has high standards for providing a product that is exceptionally fresh and free from contaminants like mercury makes it the only brand I will purchase.
