When consumed in sufficient amounts these live friendly micro-organisms provide good health benefits but there are a couple things to keep in mind
when buying a good quality probiotic. First it has to pass through the stomach acid while maintaining a good proportion of live bacteria: this is why you want to look for time release probiotics which have popped up in recent years and are great innovation. It is also important to get a supplement with strains that come from the human gut.

Health Benefits of Probiotics
Probiotics are important for gut health especially if you have been on an antibiotic which kills friendly bacteria; a probiotic will help replace the friendly bacteria and to prevent overgrowth of yeast. Probiotics improve the immune system and may reduce seasonal allergies and help stave off the flu. Probiotics reduce anxiety and depression in people with these pre-existing conditions.
Why Time Released Probiotics
It has been estimated that most of what is live in a regular probiotic supplement doesn’t make it to the intestines alive since they have to pass through the acidic environment of the stomach. The pH of gastic acid is somewhere between 1 and 3.5 so it’s quite acidic. The pH does rise after a meal so it’s easier for probiotics to get through the stomach then, however a time release probiotic will guarantee that most of the supplement makes it through to the intestines. It really matters more that most of what you start with, namely billions of CFU (colony forming units) make it past the stomach and into the intestines where they are slowly released over a period of time (such as 8 hours to 12 hours).
Look For A Brand of Time Release Probiotics that Contains Multiple Strains
Probiotics are a complicated subject but a few good rules of thumb for a general well-being promoting probiotic is to choose one with multiple strains rather than just one strain so that you can get a wider variety of benefits than just a few strains can give. Also, although not totally agreed upon, probiotics should be made from bacteria that exist in the human gut, some probiotic brands contain bacteria that exist in the soil mostly because it has proven to survive stomach acid but SBOs (soil based organisms) were never meant to live in the gut and it makes sense to replace probiotics that are supposed to live in the digestive tract.
Time release probiotics are a great innovation that allows the probiotic strains to 
pass through the acidic stomach and carry on being released into the intestines which are less acidic but still continue with digestive processes. This allows the CFU in your supplement to colonize and reach the whole length of the digestive tract slowly releasing over a period of time.
