Probiotics: Why the Strain Matters More Than the Brand
Probiotics are defined by their named strains. The strain code on the label tells you what a formula is built for, which makes choosing the right product straightforward.
What are probiotics?
Probiotics are live micro-organisms intended to confer a health benefit at adequate doses. Most products use Lactobacillus, Bifidobacterium or the yeast Saccharomyces boulardii.
A strain designation looks like Lactobacillus rhamnosus GG or Bifidobacterium lactis BB-12. That code, not the species, is what trials studied.
Africa has a strong tradition of fermented foods, from mursik and amabere amaruranu in Kenya to ogi, fura da nono and mahewu elsewhere.
Who uses them
- People taking antibiotics, using specific studied strains.
- People with certain digestive complaints, guided by strain evidence.
- People interested in fermented foods as a dietary habit.

How to compare products
Full strain designation
The strain code on the pack is what ties a product to the research behind it — worth looking for.
CFU at expiry
A count guaranteed through the expiry date tells you what every capsule supplies to the end of the pack.
Storage
Shelf-stable formulations matter in hot climates. Refrigerated products need a cold chain you may not have.
Delivery format
Enteric or delayed-release capsules aim to protect organisms from stomach acid.

Frequently asked questions
Do probiotics survive stomach acid?
Probiotic strains are chosen for acid tolerance, and many products use protective capsules. The pack states how to take them.
Are fermented foods enough?
They are a good habit with a long regional history, though strains and counts are not standardised as they are in a supplement.
