Brewer's yeast is also known as Saccharomyces cerevisiae. It is one of the few complete foods and has a slightly bitter taste. Brewer’s yeast is a non-essential nutrient, but it can be used as a source of B-complex vitamins and protein. It is by far the best source of chromium both in terms of quantity and bioavailability.

Hi simonjonez,

I admire the way you cut and paste an add, its one way to eliminate mistakes, but a little personal input wouldn't hurt, and the exercise you give the grey matter is phenomenal, may just prevent dementia, especially if it is done with a good cup of espresso/cappuccino. http://www.healthcastle.com/podcast-018.shtml
