Probiotics — A Simple Guide
Key strains, how to choose, how to take, and safety notes. Educational only; not medical advice.
What are probiotics?
Probiotics are live micro-organisms that, when taken in adequate amounts, support a healthy balance of gut bacteria. Products differ by strain, dose (CFU), and delivery.
Common strains & typical uses (overview)
| Strain (example) | Notes (typical use) |
|---|---|
| Lactobacillus rhamnosus GG | General gut support; well-researched. |
| L. plantarum | Gas/bloating balance; broad GI support. |
| Bifidobacterium lactis | Regularity; stool consistency. |
| B. longum | Gut–brain axis; calm support. |
| Saccharomyces boulardii (yeast) | Travel/antibiotic adjunct; stool balance. |
| Bacillus (spore-forming) | Hardy; survives heat/acid; diversity support. |
Strain = specific subtype. Choose products that list strains (not just species).
How to choose (quick tips)
- Match the goal: regularity, bloating, travel, post-antibiotic, etc.
- Check strain names (e.g., L. rhamnosus GG), not just species.
- CFU & dosing: follow label; higher isn’t always better.
- Format: fridge-stable vs shelf-stable; capsules vs powder.
- Extras: prebiotics/fibres can be helpful—or too much if sensitive.
How to take (general)
- Follow the product label; many can be taken with or without food.
- Introduce slowly if sensitive; consistency matters more than timing.
- If using antibiotics, separate doses (e.g., by a few hours).
Safety notes
Check labels for allergens. People with severe illness/immunocompromise should seek medical advice before use.
