The public should be wary of searching for probiotic information online as most webpages originate from unreliable sources and the health-benefit claims are often not supported by robust scientific evidence.
A new study, published in Frontiers in Medicine, cautions that while Google is adept at sorting the most reliable websites to the top of the list, the majority of websites providing information on probiotics are from commercial sources.
If you stick to the obvious benefit of replacing "good" bacteria following gastroenteritis or use of broad spectrum antibiotics, I don't think you can go far wrong with using probiotics, though their efficacy may vary between suppliers and even batches. But I agree that some of the other claims are based on very flimsy evidence, if that!
