Question 1

What is the difference between a prebiotic and a probiotic?

Accepted Answer

Probiotics are living bacteria you consume. Prebiotics are fibers that feed those bacteria. Your body digests probiotics (they pass through). Your bacteria digest prebiotics (through fermentation in your colon).

Question 2

Can you take probiotics and prebiotics together?

Accepted Answer

Yes. This combination is called a synbiotic. The prebiotic feeds the probiotic, improving survival and colonization. Food naturally combines them (kimchi contains both). Supplements can too, though dosing often falls short in pill form.

Question 3

What are examples of postbiotic foods?

Accepted Answer

Any fermented food contains postbiotics along with probiotics. Kefir, kombucha, aged cheese, and traditional sourdough all provide bacterial metabolites produced during fermentation. Butyrate supplements also exist but getting it from food works better.

Question 4

Do postbiotics have side effects?

Accepted Answer

Minimal. Because they contain no live organisms, postbiotics don't cause infections. Some people report mild digestive changes initially as their gut adapts. Gas, bloating, or changes in stool consistency usually resolve within one week.
