Bifidobacterium lactis is a widely studied probiotic often used in combination with L. acidophilus. When used in combination with L. acidophilus, studies suggest that B. lactis may reduce abdominal pain scores and symptoms in individuals with IBS, and in children may reduce the duration of acute respiratory infections.

Neither an artichoke nor from Jerusalem, the Jerusalem Artichoke is actually sunflower root. This root is a natural prebiotic, high in fiber–stimulating and feeding the Bifidobacteria (the good guys!) in the gut.[1]

Lactobacillus rhamnosus is a probiotic that's been widely studied for its potential health benefits.
When combined with L. acidophilus DDS®-1, L. rhamnosus has been shown in studies with healthy children to help alleviate digestive discomfort including occasional gas, bloating, and irregularity.†
L. rhamnosus may be beneficial by changing the amount of reactive oxygen species like nitric oxide, which impacts blood supply to tissues. Other studies have shown that L. rhamnosus may reduce diarrhea and abdominal stress in individuals taking antibiotics.
