What Is In a Probiotic?

Although there may be hundreds of different probiotic products in the marketplace, many products may contain the same strains. Probiotics are identified by genus (for example, Lactobacillus), species (for example, acidophilus) and strain (for example, NCFM). Manufacturers should provide information on their product labels or website that includes:

  • The genus, species and strain of all probiotics in the product.
  • The level of all probiotic strains in the product expected at the end of shelf life.
  • The health benefit(s) associated with the product, including references when possible.
  • Proper storage conditions of the product.
  • Recommended usage based on the level shown to be effective in studies.
  • Contact information for the company.
