Supports digestive balance
The daily baseline: less gas, less unpredictability, more of a gut you don't have to think about.
20 billion CFU across targeted Lactobacillus and Bifidobacterium strains — the genera with the most human research behind women's digestive and urogenital health.
WHY IT WORKS
Probiotics are strain-specific — 20 billion CFU of the wrong thing does nothing for you. Lactobacillus species are the genus most studied in women's health, and they're the backbone of this formula rather than a sprinkle on the label.
The daily baseline: less gas, less unpredictability, more of a gut you don't have to think about.
The genus with the deepest human research base in women's digestive and urogenital health — which is why it leads this formula.
A large share of immune tissue sits in the gut lining. Supporting one supports the other.
A common reason women start a probiotic in the first place — and one of the better-evidenced reasons to take one.

The Research
Multi-strain probiotics are among the better-studied gut supplements. Here are the sources.
A systematic review found probiotics improve lower-GI symptoms such as bloating and irregularity in the general adult population.
The gut microbiota is central to immune function, and probiotics can modulate immune responses and support the gut barrier.
Lactobacillus and Bifidobacterium strains are among the most-studied probiotics for digestive balance and are considered safe and beneficial in healthy adults.

Good Questions
This 20B is the approachable daily foundation — a great everyday dose. The 40 Billion with Prebiotics is higher-potency and adds prebiotic fiber (a synbiotic) for people who want more support or have more going on.
Less than the marketing suggests. Strain identity and whether the organisms survive to your intestine matter more than a big number on the front. 20 billion CFU of well-chosen, shelf-stable strains outperforms 100 billion of something that dies in your stomach acid. Anyone selling you purely on CFU count is selling you the easiest number to print.
Probiotics are widely used in pregnancy, but we're not the right authority on your pregnancy — ask your OB or midwife before starting anything, including this. That's not us dodging the question; it's genuinely the right call.
Yes, and it's especially useful for replenishing beneficial bacteria afterward. Take it a few hours apart from the antibiotic dose.
Well tolerated for healthy adults. If you're immunocompromised, seriously ill, or pregnant or nursing, consult your physician first.
