No probiotic is best for everyone, because benefits are strain-specific. As of October 2026, Now Foods Probiotic-10 is the most transparent South African option we found (25 billion CFU, ten named strains, R11.25 per capsule on special), while New Leaf is a cheaper single-strain choice at R6.65 per serving. Evidence in athletes is emerging, so match strains to your goal.
Disclosure is uneven, which is the main problem for buyers. Prices are from Faithful to Nature and Dis-Chem Living Fit, October 2026.
| Product | What the label states | Pack and price | Price per serving |
|---|---|---|---|
| New Leaf High Strength Probiotic | 2 billion CFU, one strain (L. acidophilus), 2 tablets daily; no refrigeration needed | 120 tablets, R399 | R6.65 |
| Food Grown Broad Spectrum Probiotic | 10 strains (HOWARU brand), strains not named, CFU not stated, 2 capsules daily | 60 vegecaps, R327 (Dis-Chem Living Fit) | R10.90 |
| Now Foods Probiotic-10 | 25 billion CFU, 10 named strains, 1 capsule 1 to 2 times daily; contains FOS | 30 capsules, R337.49 special (R449.99 regular) | R11.25 (R15.00 regular) |
| Klean Nourish Probiotic Blend | 8 strains, "20 billion CFU per gram" (per-capsule CFU not stated) | 30 capsules, R389 | R12.97 |
The ISSN position stand stresses that probiotic effects are strain-specific and dose-dependent, so a bigger CFU number or more strains does not make a product better. Trials generally use roughly 1 billion to 100 billion CFU a day of named strains. Ask three questions:
Evidence is emerging. Some strains may modestly reduce the frequency or duration of upper-respiratory infections and gut symptoms in athletes, and may lower the risk of diarrhoea during antibiotic use. Performance effects are inconsistent. The AIS places probiotics in Group B (emerging evidence), to be used with an individual protocol.
Viability depends on storage. Check expiry and storage instructions, because summer temperatures in a car, gym bag or non-air-conditioned shop can damage live cultures. New Leaf states that refrigeration is not needed; the Food Grown page shows no refrigeration instruction; we did not see storage instructions for the others in the text we read. Keep the pack cool and dry regardless. See how to store supplements in South African heat.
Avoid probiotics, or speak to your doctor first, if you are severely immunosuppressed, critically ill or have a central line. Everyone else can generally take them safely, but if symptoms such as blood in stool, fever or persistent diarrhoea appear, see a doctor rather than self-treating.
Our recommendation: if you want to trial a probiotic, start with a product that names strains and gives CFU per capsule (Now Foods is the only one of the four that does both), take it daily for several weeks, and stop if there is no benefit. Read how to read a supplement label and which supplements actually work.
