Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. 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 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)

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. , ,
