Swanson’s #1 best-selling customer favorite probiotic, Dr. Stephen Langer's Ultimate 16 Strain Probiotic includes more than four times the number of strains compared to many popular probiotic formulations. While other supplements provide only two strains of bifidobacteria, Dr. Langer's formula delivers four. And while some have only one strain of lactobacillus, we feature eleven, including L. reuteri, which was recently added to improve the formula because of the unique protective abilities it offers for colon health and immune system function. Along with S. thermophilus, this variety of probiotic strains encourages a diverse microbiome for better overall digestive health compared to single-strain formulas.

And that's not all. A synbiotic formula, it also includes prebiotic FOS. Fructooligosaccharides (FOS) are naturally occurring plant compounds. They are non-digestible, meaning they arrive in the intestines intact where they function as prebiotics, i.e., ‘food’ for probiotics, and promote intestinal integrity. Additionally, we feature ConcenTrace® trace minerals, which you won't find in just any off-the-shelf product. Prebiotics and trace minerals are absolutely vital to the enzymatic processes necessary for healthy digestion and the maintenance of beneficial bacteria.
