of course I'm not a professional health professional but I have done some research on this. I've also spoken to some physicians.
IMHO, probiotics are a huge scam. However the one time they Might actually do some good is after a course of antibiotics.
As far as I can tell there are no studies proving that show probiotics are helpful. One researcher gave an interview and he even went as far as saying that among his patients they might have actually been harmful. (keep in mind that these were his patients because there were already things wrong with them).
He also pointed out that a lot of these bacteria probably don't even survive passing thru the stomach. their intended living area is the intestines which is not as acidic.
I also like to point out that our guts have hundreds (maybe thousands) of different species of bacteria. All living together and competing, cooperating, and in some cases devouring each other in complicated relationships and ratios. It's actually a little ecosystem that probably is as complicated as any forest.
I read that the bacteria in our guts are so unique that there is an emerging forensic science that hopes to identify people with them. Like fingerprints or blood types.
I know analogies have their weaknesses but I love them. So let's take a forest and burn it down. (your gut on probiotics). and then you come in and plant a dozen different plants, animals and bugs. (that's the probiotics) Well, you can't expect it to be the same. but just like the forest, the other species will find their way into the forest.
Keep in mind that your gut has all those different species. The best probiotic has no more than 60.
But like when a forest fire is over they do come in and give the forest a jump start by planting some trees and grasses.
Anyway, if I was looking to take a probiotic I would look for the one that has the most number of species.
I've know that there is a lot of correlation between the number of species and the price. And I would be very hesitant in spending really big bucks on something that may not even work.
BTW, I don't take them unless I've taken some antibiotics. But then I'll buy a bottle and take the recommended dose till its gone.
