At 25 billion CFU per capsule, you're getting a solid dose for everyday digestive and immune support — comfortably within the 1–100 billion CFU range used across clinical research. Take the label's suggested two capsules daily and you're at 50 billion CFU, which puts you in the middle of the studied range without overdoing it.

All 10 strains come with strain-level identification (LA-14, BL-04, LR-32, etc.), which matters because probiotic benefits are strain-specific, not just species-specific. The formula also includes **fructooligosaccharides (FOS)**, a prebiotic fiber that feeds beneficial bacteria and can help your new probiotics establish themselves in the gut. The blend covers both **Lactobacillus** and **Bifidobacterium** species, giving you broad coverage across the small and large intestine.

The main caveat: individual strain doses aren't disclosed — you're getting a 160mg proprietary blend, so you can't tell how much of each strain you're actually taking. If you're targeting a specific condition like IBS or antibiotic recovery, a single-strain product with published clinical trials at a defined dose may serve you better.
