Differentiating between probiotics Part 1
We are often asked what is the difference between the readily available probiotics on the market. In part one of this series we compare (Natto) and (boulardii).
Both the bacteria Bacillus Subtilis (Natto) and the yeast Sacchormyces cerevisiae are spore producing probiotics, however it is here that the similarities may end.
