Prebiotics, Probiotics and Synbiotics: What's the Difference?

Walk down any supplement aisle and you’ll see the same few words again and again. They sound alike, but they describe very different things. Knowing the difference makes labels, including Sodatide’s, much easier to read.

Probiotics: the microbes

Probiotics are live microorganisms, usually bacteria and sometimes yeasts, that are added to foods or supplements. Fermented foods such as yoghurt with live cultures, kefir, sauerkraut and kimchi are traditional sources. In a supplement, probiotics are normally identified by genus and species (for example Bifidobacterium infantis) and ideally by a strain code and a count in colony-forming units (CFU).

Prebiotics: the food for those microbes

Prebiotics are fibres and related compounds that your own body doesn’t digest but that gut bacteria can ferment. Common examples are inulin and other fructans, found in chicory root, onions, garlic, leeks and asparagus, and resistant starch, found in legumes, slightly green bananas and cooked-then-cooled potatoes or rice.

Synbiotics: both together

A synbiotic is a product that combines prebiotics and probiotics. The idea is straightforward: supply microorganisms and, alongside them, a fibre they or other resident bacteria can use. Sodatide describes itself as an advanced synbiotic. Each capsule pairs chicory root inulin and potato resistant starch with a blend naming three species.

Postbiotics are a newer term for the beneficial compounds microbes produce, or for inactivated (for example, pasteurised) microbes. Short-chain fatty acids made during fibre fermentation are a common example.

How to read a probiotic label

  • Species named? Good labels name each organism.
  • Strain codes? Strain-level identification lets you match an ingredient to specific research.
  • Counts? CFU (or AFU) tells you how many organisms each serving is meant to contain.
  • Storage? Some products, Sodatide included, ask you to refrigerate them.

Sodatide’s panel names three species in a 36 mg blend but doesn’t list strain codes or CFU counts, which is worth knowing if those details matter to you.

The bottom line

Probiotics are the microbes, prebiotics are their food, and synbiotics are both in one. None of them replace a varied, plant-rich diet, which remains the biggest single source of prebiotic fibre for most people.
