Probiotics: What It Is, What It Brings and How to Choose a Supplement
Also known as Live cultures, Lactobacillus, Bifidobacterium
Probiotics are friendly live cultures that carry on Africa’s long tradition of fermented foods in a convenient capsule. With probiotics the named strain is the key, because each strain brings its own character.
What is probiotics?
Probiotics are live micro-organisms that, in adequate amounts, are intended to confer a health benefit. Most commercial products use Lactobacillus, Bifidobacterium or Saccharomyces boulardii.
Benefits are strain-specific, which is why quality products name each strain on the label.
Traditional and regional use
Fermented foods are traditional across Africa — mursik and amabere amaruranu in Kenya, ogi and fura da nono in West Africa, mahewu in southern Africa. These are the region’s original probiotic foods.
What is probiotics known for?
Good to know. Supplements containing probiotics are food supplements, so their labels describe support for everyday wellbeing.
Specific strains have shown consistent results in keeping digestion comfortable during and after a course of antibiotics.
Researchers have also studied probiotics for everyday digestive comfort and bowel regularity, which is why they sit at the heart of day-to-day gut wellbeing.
How is it used in supplements?
Probiotics are sold as single-strain and multi-strain capsules, often with prebiotic fibres. Colony-forming unit counts range from one billion to hundreds of billions.

How to choose a supplement containing probiotics
- Look for the full strain designation, for example Lactobacillus rhamnosus GG, not just "Lactobacillus".
- Check the CFU count at the end of shelf life, not at manufacture.
- Confirm storage requirements — heat is the enemy of live cultures in tropical climates.

Frequently asked questions
Is more CFU better?
The named strain and its studied amount matter most. A well-chosen strain at the amount on the label is the goal.
Can fermented milk replace a supplement?
Traditional fermented dairy supplies live cultures and is a wonderful dietary habit. A supplement adds named strains in a standardised count, and the two combine well.
