The study looked at blood tests and brain scans from more than 11,000 women and the findings were consistent. What's important, however, is that the hippocampus area of the brain-responsible for memory-increased in volume when higher levels of omega-3 were found. This is notable because the hippocampus begins to shrink long before the symptoms of Alzheimer's ever appear. If fish oil increases the volume of this area of the brain, it's possible it can reduce the risk of Alzheimer's and delay its onset.
So how much fish oil should you take every day? More than the recommended daily intake and more than the suggested serving listed on the bottle. You can elect to purchase capsules or liquid oil, and the servings vary. I choose the liquid version.
The data indicates an effective therapeutic dose of fish oil is 1,000 mg to 1,500 mg. Depending on the content of your liquid, it's about two teaspoons. With pills, the serving size is a little more dicey. A typical one gram pill, for example, will only have about 300 mg, or 30%, of an effective daily dose, meaning you'll have to take five pills to experience the real benefits.
Therefore, make sure you read the label to know how much you're getting, how much you need to take, and the value of the brand you select. At the end of the day, fish oil has almost too many benefits to list. If you haven't tried it yet, make sure you do-and that you take an effective dose!
