Probiotic 100 Billion Benefits I recommend probiotics to everyone. In fact, probiotics are one of the four essential supplements that I recommend my patients take every day. We have more bacteria in and on our bodies than we have actual human cells in our body. We live symbiotically with them, and when they are in balance, they promote optimal digestion and immunity, both of which are crucial to every aspect of your health and well being.† My Probiotic Capsules 100 Billion are some of the strongest probiotics on the market today. When I formulated my 100 Billion strength probiotics, I chose 14 of the most important strains, and made absolutely sure that there were enough viable CFU’s (Colony Forming Units) in each capsule to support maximum digestive health and immune function.
