Probiotics are live bacteria and yeasts that are often labelled as “good” and “helpful”, especially in the case of your digestive system.
But do they actually work?
The science isn’t there yet. Claims stating that probiotics will improve your digestive capabilities and immune function have not been proved.
A study evaluated 16 probiotic products to determine how well their ingredient list matched what’s actually in the bottle. Only 1 passed.
For most people, there is no likely harm with taking probiotics, except possibly some damage to your wallet.
If you still want to take probiotics, at least read the Clinical Guidelines to Probiotic Supplements and look for billions of CFU (colony-forming units) and higher clinical ratings (Levels I-III).
