Hi, everyone. Recently I've been taking "Renadyl", a probiotic dietary supplement to help maintain kidney function. My monthly lab tests showed a reduction in the protein related numbers. However, my phosphorous wasn't affected. I also noticed an improvement in my digestion and constipation. But these are expensive, and have to be refrigerated. Life Extension's new probiotics capsules have two capsules. This prevents the stomach acid from killing the bacteria before it can reach your intestines and do you some good. It works even better, 12 million critters per pill. My constipation problems are a thing of the past! Yahoo. It's about $30 for a 1 month supply. My health food store guy has been taking probiotics for 30 years, and he says this new delivery system is the new wave for probiotics. It's a hassle to have to refrigerate probiotics. And it's expensive. The new capsules are better, in my humble opinion.
