Probiotics in South Africa: How to Choose the Right One (and Why Most Don't Work)
Probiotics are one of the most popular supplements in the world — and one of the most misunderstood. The uncomfortable truth is that most standard probiotic supplements on the shelf never reach your gut alive. Here's what you actually need to know to buy a probiotic that works.
What Are Probiotics?
Probiotics are live microorganisms — primarily bacteria and yeasts — that, when consumed in adequate amounts, provide a health benefit to the host. They work by colonising the gut, competing with pathogenic bacteria, producing beneficial metabolites, and supporting the gut-immune interface.
Your gut microbiome contains approximately 100 trillion microorganisms from hundreds of species. When this community is disrupted — by antibiotics, poor diet, stress, or illness — health consequences follow. Probiotics help restore and maintain this balance.
Why Most Standard Probiotics Don't Work
The biggest problem with most commercial probiotics is survivability. Standard probiotic strains (like Lactobacillus and Bifidobacterium) are fragile. They're killed by:
- Stomach acid (pH 1.5–3.5)
- Bile salts in the small intestine
- Room-temperature storage
- The manufacturing process itself
Most studies estimate that only 1–10% of standard probiotic CFUs (colony-forming units) survive transit through the stomach to reach the colon where they're needed. This explains why so many people feel no benefit from taking standard probiotic capsules.
The CFU number on the label is also often misleading — it measures bacteria at the time of manufacture, not at the time you take it, and certainly not at the time it reaches your colon.
Spore-Based Probiotics: A Fundamentally Different Approach
Spore-based probiotics represent a significant advance in probiotic science. Instead of fragile Lactobacillus strains, they use Bacillus species in their naturally occurring spore form.
Bacterial spores are dormant, highly resilient structures — the microbial equivalent of seeds. They can survive: - Extreme stomach acid (no degradation in transit) - High temperatures (stable at room temperature) - Antibiotics (many spores survive antibiotic treatment)
Once they reach the colon, the spores germinate, bloom and establish themselves. Clinical research on Bacillus coagulans, B. clausii and B. subtilis strains shows significantly better gut colonisation rates than standard strains.
Florish Spore Probiotics — available at WellnessTree — uses a clinically validated blend of Bacillus spore strains, along with prebiotic FOS to feed the colonising bacteria.
What to Look for in a Probiotic
Strain specificity: Different strains do different things. Lactobacillus rhamnosus GG is well-studied for diarrhoea; Bifidobacterium longum for IBS; Bacillus spores for general microbiome restoration. The strain matters — not just the genus.
Survivability: Look for spore-based formulas, enteric-coated capsules, or strains with documented acid-survival data.
CFU count: 10–50 billion CFU is typical for therapeutic use. More isn't always better — strain quality and survivability matter more than raw numbers.
Prebiotics: The best probiotic formulas include prebiotic fibres (FOS, inulin, GOS) that feed the probiotics once they reach the colon.
Storage: Spore-based probiotics don't require refrigeration. Standard Lactobacillus strains should be refrigerated — if a standard probiotic is stored at room temperature, question its viability.
When to Use Probiotics
After antibiotics: This is the most evidence-backed use case. Probiotics reduce the duration of antibiotic-associated diarrhoea and help restore microbiome diversity. Start during the antibiotic course (take 2+ hours apart) and continue for 4–8 weeks after.
IBS and digestive discomfort: Multiple strains have demonstrated efficacy for IBS, bloating and altered bowel habits. Look for multi-strain formulas with clinical data.
Immune support: Approximately 70% of the immune system is located in the gut. Probiotic supplementation has been shown to reduce the incidence and duration of upper respiratory infections.
General microbiome maintenance: A daily probiotic is a reasonable wellness practice for anyone with dietary limitations, high stress, or a history of antibiotic use.
