One of the cheaper yet so overlooked vitamins, I am living proof that B3 is effective to eliminate brain fog in the mornings, and arthritic pain. It is a month that I have followed Dr. Hoffer's instructions and the side effects at the beginning are nothing compared to the serenity and peace I encountered. The achy feeling in the skull and neck cervical vertebrae is disappearing. He recommends it for mental inbalances, aging, etc. etc.
Dr. Hoffer took B3 at 3,000 mgs level for 50 years, and his website centers on the benefits of this vitamin. Currently I take 5,000 mgs spaced through the day, having started at the initial 500 mgs. The flushing effect so well described is quite tolerable and he explains that excess is excreted by the body.
Here's the site in memory of Dr. Abraham Hoffer:
A pesky situation happens when one tries to navigate down the tabs provided but eventually they all come up. The common element amongst all tabs is his valuation of B3, you will see it ...
To your good health !
