A study published online in the Alzheimer's Association journal Alzheimer's & Dementia: The Journal of the Alzheimer’s Association found that supplementation with algal DHA omega-3 may help support the memory of healthy older adults. The Memory Improvement with Docasahexaenoic Acid Study (MIDAS) is the first large, randomized and placebo-controlled study demonstrating the benefits of DHA in supporting brain health in older adults.
MIDAS found that healthy people with memory complaints who took 900 mg algal DHA capsules for six months had almost double the reduction in errors on a test that measures learning and episodic memory performance versus those who took a placebo. The DHA was well-tolerated and subjects taking the DHA also experienced a lower heart rate, providing a significant cardiovascular benefit.
The study population included 485 people age 55 and older at 19 U.S. sites who were considered to have experienced a minor memory complaint such as remembering names or appointments.
