Dr. dodge, welcome to HealingWell! I hope you get some great information here and continue to post.
Chesswoman, probiotics are "good bacteria" that our intestines need to function properly. You find them in yogurt products and/or by taking a supplement. I believe the most common probiotic is Acidophilus. Many of us here take probiotics daily. In addition, many of us are on a combination of probiotics. I take Kyo-Dophilus, Phyto Pharmica Probiotic Pearls and Acidophilus. Here is a great link to give you info: about probiotics
Take care.
