"This study reinforces the principle that consumers will reap the most benefit from their DHA supplements-and many supplements-when they are taken over time and before a health concern is imminent," continued Dr. MacKay. "When included as a part of a proactive health regimen that includes a well-balanced diet, regular physical activity and routine visits with a healthcare professional, dietary supplements offer an important tool to help support many systems in the body, including memory and cognitive function."

The MIDAS study was conducted in a total of 485 subjects, aged 55 and older with a subjective memory complaint and who met criteria for age-related cognitive decline (or "age-associated memory impairment"). Subjects were randomly assigned 900 mg/d of algal DHA orally or a placebo for 24 weeks.

DHA is an omega-3 fatty acid and is available as a dietary supplement. Many Americans turn to dietary supplements each year help manage age-related challenges. According to CRN's Consumer Survey on Dietary Supplements, among Americans aged 55+ who take supplements, 13 percent report they do so for "memory" and 39 percent for "healthy aging."
