Krill oil’s a must…
“When your omega-3 intake is inadequate, your nerve cells become stiff and more prone to inflammation as the missing omega-3 fats are substituted with cholesterol and omega-6 instead. Once your nerve cells become rigid and inflamed, proper neurotransmission from cell to cell and within cells become compromised.
It’s thought that the unsaturated fatty acid composition of normal brain tissue is age-specific, which could imply that the older you get, the greater your need for animal-based omega-3 fat to prevent mental decline and brain degeneration.5
For example, low DHA levels have been linked to memory loss and Alzheimer’s disease, and research suggests degenerative conditions can not only be prevented but also potentially reversed. For example, in one study, 485 elderly volunteers suffering from memory deficits saw significant improvement after taking 900 mg of DHA per day for 24 weeks, compared with controls.6
Another study found significant improvement in verbal fluency scores after taking 800 mg of DHA per day for four months compared with placebo.7 Furthermore, memory and rate of learning were significantly improved when DHA was combined with 12 mg of lutein per day.” Dr. Mercola
