2000mg of Niacin per day is an effective means of curtailing Alzheimer plaque formation in humans.

Too much is toxic to the liver and 1000 is too little to do much good. If I were you I would by the flush free B3 Niacin and take 4 a day.

I have been doing this for about 9 months now at the behest of my physician.

This claim is based on NIH research that is not yet cleared for humans but has shown to be a 78% cure for Alzheimers in rat studies.
