For over a century, a variety of good bacteria has been extoled as a means to improve our general health. Today, these helpful microbes are better known as probiotics. When taken, according to the definition, a person can expect to receive some form of a health benefit. The actual list of probiotic species is relatively small with the majority of species coming from the Lactobacillus or Bifidobacterium genera. Yet, while these two are dominating the probiotic field, other species have slowly made their way from the papers of academia to store shelves.
