My personally, I'm a huge fan of getting a probiotic no matter what your state of health. As there are so many benefits to investing in this supplement. Even so you must be cautious which you are taking given that a wide range of these are lousy quality. The most beneficial one should have many different strains of healthy and balanced bacterias. And in case you can find one that's stable at room temperature, then that is a bonus.
