I have been using Theralac for 5 years and have had only mild symptoms of the flu and its' duration was about 3 days. I started using it when I found out I had cancer. There were no side effects from the treatments, not sure if it was the Theralac that helped, but it sure didn't hurt. My daughter and her family also use it but not consistently so their results differ. I highly recommend using it everyday. It also helped with my digestion and heartburn.

Thank you David!
When I called to place my order, the employee was very helpful in regards to how I could save money and still receive my product of TruBifido on time. Thanks so much for your assistance. We need more people like you employ.

That simple things is everything we do really need in our days anyway for whatever reason there. I am just hoping it will workout for anything being done there with everything. Let's assume it's all doable for you with your health state, cause not always it's all possible.

I've used Theralac for years for its results, quality, and service. I wouldn't have used it 2 months if all three were not true.
