probiotics supplements - good enough?

I have been giving G probiotics since he came down with a 24-hour stomach virus back in September.  K has recently started rice cereal so I purchased a brand that offers probiotics in the mix.  I figured since she is too young for a flu shot why not play it safe? But with past studies regarding the actual benefit from some vitamins, I have been leary of these supplements too. I decided to do a little research.  Found is a quick article from Health.com and Glamour.com giving details about a recent study on probiotics.  As always, getting your probiotics through food is the best and yogurt is the most obvious choice.  I keep a large tub of low fat organic vanilla yogurt in the fridge for fruit smoothies and G's favorite dessert (drizzled with a little chocolate sauce with fresh strawberries or blueberries). So far so good.  With the flu scare out there who knows what the winter season will bring but at least we are working on keeping everyone healthy.
