The medical community for the most part are ignorant egotists. They were never taught anything about nutrition. You will not overdose with the regimen. But as I said, believe who you want. I am tired of the second guessing.

btw, The RDA (Recommended Daily Allowance) is the minimum amount needed to maintain a "minimal" health and avoid malnutrition. The Life Extension Foundation you linked to suggest MUCH higher doses that anything in the regimen.

The The Cerefolin Nac has 2000mcgs (2 mgs) of B-12. I recommended 2500 mcgs because it is a common dose that is readily available. Besides, very little of it makes it into the blood stream.

Vitamins and supplements are not a cure. They just help the brain tolerate stress and put it in a better state to try to heal.
