I love sauerkraut, I always have, even as a kid (Polish half of my family always served sausage and kraut for Thanksgiving, LOL)
I can't say whether I benefit from the probiotics, but it doesn't seem to hurt. Bubbies brand is all natural, fermented, probiotic-rich, etc. if you can find Bubbies I'd recommend it. The stuff that comes in a can probably won't do anyone any good. It's not really all that hard to make, but it is rather time consuming.
