Why are there so many different types of probiotics?
If you know anything about bacteria, you probably know that you contain a multitude. The bacterial cells in your body outnumber your human cells by about 3 to 1 ratio, technically making you more bug than human. This fact also helps explain why your local pharmacy carries so many varieties of probiotics. Stare too long and you’ll likely wind up with a furrowed brow, wondering where you should even begin. Start with the U.S. Probiotic Guide to get a thorough look at the tons of different types of probiotics, advises Keith Ayoob, MD. It lists the hundreds of different bacteria cultures, capsules and varieties that are available.
