Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host.[1] They are present in numerous products, most commonly in foods and supplements.


Numerous clinical studies have reported roles probiotics can play in keeping us healthy. Probiotics have been shown to:

  • help with digestive issues such as occasional bloating, gassiness, stomach pain, diarrhea and constipation
  • support immune system functions[2] as well as oral and women’s health
  • provide helpful roles in maintaining healthy physiological parameters such as normal cholesterol levels, body weight and blood glucose levels, to name a few


Organisms and species commonly used as probiotics include:

  • Lactobacillus species
  • Bifidobacterium species
  • Certain Bacillus species
  • Non-bacterial organisms like Saccharomyces (Yeasts)



The following are additional resources on probiotics, including fact sheets and links:


Nature Made Probiotic Products Overview

Current Nature Made Probiotic products contain a Lactobacillus organism (Lactobacillus plantarum 299v), the Bifidobacterium organism (Bifidobacterium lactis SD-5674) or a combination of both, targeting digestive health.

L. plantarum 299v helps support a healthy balance of intestinal microflora, and B. lactis SD-5674 supports regularity. These health claims are supported by well-designed and executed human clinical studies. [2], [3], [4]


Below is a snapshot of Nature Made’s newest probiotic products.
