Help Prevent or Slow Alzheimer’s Disease
DHA is the most abundant omega-3 lipid in your brain and is required for a healthy neurological system, which includes your brain. According to research, people with Alzheimer's disease had lower DHA levels in their brains than older adults with normal brain function. Furthermore, in a meta-analysis of 20 observational studies, higher omega-3 fat intake was connected to a lower risk of diminishing mental capacity — a feature of several types of dementia, including Alzheimer's disease — in all but three studies.
However, eight of the 13 studies that looked at the impact of omega-3 supplementation on persons with dementia found a benefit for mental function, whereas five did not. According to the data, DHA and other omega-3 supplements may be most effective before brain function diminishes considerably and interferes with daily tasks.
