Prebiotic, probiotic, and postbiotic—in plain English
- Prebiotic: fermentable fibers (e.g., inulin/FOS/GOS/PHGG) that your microbes eat.
- Probiotic: live microbes with a benefit when taken in the right strain and dose.
- Postbiotic: the helpful compounds microbes make (e.g., short‑chain fatty acids).
You can buy these separately, or in combo products. The best choice is the one you’ll take daily.
