Buying Guide

CFU count matters

Look for clinically relevant CFU ranges like the 30–60 billion options shown here; higher CFU can support colonization but match dose to your needs

Check strain diversity

Multi-strain formulas (for example 10–12 strains) offer broader microbial functions than single-strain products and may target both digestion and immune support

Prefer acid-resistant delivery

Acid-resistant capsules or enteric coatings help more live bacteria survive stomach acid so they reach the gut intact

Consider added ingredients

Formulas with prebiotics or botanicals (such as organic prebiotics or adaptogens) can support probiotic activity but verify compatibility with your health needs
