Probiotics: Are They Really Necessary? | Talking Point | Diet
Bacteria.
Fungi (including yeasts).
Viruses.
Protozoa.
Everyone’s microbiome is unique. No two people have the same microbial cells — even twins are different.
For a microbe to be called a probiotic, it must have several characteristics. These include being able to:
Be isolated from a human.
Survive in your intestine after ingestion (being eaten).
Have a proven benefit to you.
Be safely consumed.
