What is yeast?

Naturopathic Medicine
Yeasts are single-cell organisms that convert their food, through a process called fermentation, into alcohol and carbon dioxide -- a trait that in the case of brewer's yeast (Saccharomyces cerevisiae [S. cerevisiae]) has endeared it to the brewers of beer and ale, the two alcoholic beverages for which this yeast, whose species name is derived from the Latin word for "beer," cerevisia, works best. While varieties of yeast abound, very few species provide a significant benefit to humans. Within the small group of human-friendly yeast organisms, S. cerevisiae is perhaps the most beneficial of all, since both brewer's and baker's yeast are strains of this species.

Some of them are backed by solid research, others are folk remedies or proprietary cures. If your diet does not include enough of certain vitamins or minerals, a supplement may be a good idea. Natural treatment for conditions like constipation may be effective. But because these substances are unregulated, it is always a good idea to educate yourself about the products and to use common sense when taking them. This is even more true if you are pregnant or taking a medicine that may be affected by supplements.
