DHA supplementation improves cognition in older adults with mild cognitive impairment

October 11, 2016

Results from a recent study published in the Journal of Alzheimer's Disease support the cognitive benefits of DHA, which have been consistently demonstrated with doses of 900 mg/day or greater. The study, which took place in Tianjin, China, was a randomized, double-blind, placebo-controlled trial in 240 (219 completed) Chinese individuals aged 65 and older with mild cognitive impairment. The participants received either 2g/day of DHA or a corn oil placebo for 12 months and specific measures of cognitive function were measured at baseline, six months and 12 months.

The study results showed that there was a significant difference in the Full-Scale Intelligence Quotient (IQ) in the DHA group versus placebo, with IQ in the DHA group measuring 10% higher than the placebo group. Additionally, there were statistically significant increases in two IQ sub-tests (Information and Digit Span). The Information and Digit Span Subdomains are considered indicators of long-term and short-term memory, respectively. The findings suggest that DHA supplementation of 2g/day for 12 months in MCI subjects can significantly improve cognitive function.

While additional larger longer-term studies are needed to confirm the results, this paper adds to the body of science supporting DHA omega-3s and their role in supporting cognitive function.

#521 The Curious Life of Krill
Krill may be one of the most abundant forms of life on our planet... but it turns out we don't know that much about them. For a create that underpins a massive ocean ecosystem and lives in our oceans in massive numbers, they're surprisingly difficult to study. We sit down and shine some light on these underappreciated crustaceans with Stephen Nicol, Adjunct Professor at the University of Tasmania, Scientific Advisor to the Association of Responsible Krill Harvesting Companies, and author of the book "The Curious Life of Krill: A Conservation Story from the Bottom of the World".
