DHA supplementation improves cognition in older adults with mild cognitive impairmen

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.
