Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Previous animal studies have indicated that Krill oil may have the ability to improve cognitive function. Therefore, the investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of Krill oil on cognitive function in adults with subjective memory impairment for 12 weeks; the safety of the compound are also evaluate. The Investigators examine chemical and metabolic parameters, and cognitive function at baseline, as well as after 6 and 12 weeks of intervention. One hundred adults were administered either 500 mg of Krill oil or a placebo each day for 12 weeks.
