What Makes a Good Probiotic? (What to Look For)
Before diving into our picks, here is what actually matters when choosing a probiotic in NZ:
- Strain diversity — look for multiple strains including Lactobacillus acidophilus, Bifidobacterium longum, and Lactobacillus rhamnosus.
- CFU count — Colony Forming Units measure how many live bacteria are in each dose. For general gut health, 10–50 billion CFU is a reasonable range.
- Survivability — the bacteria need to survive your stomach acid and reach your intestines. Look for delayed-release capsules.
- Shelf stability — some probiotics require refrigeration, others do not. Check storage requirements before buying.
- Transparency — reputable brands publish third-party testing results.
