I have used many different probiotics and none seemed effective until I started using your product. Very effective probiotic. I take it every day and I have noticed less digestive problems. Our subscription delivery is always on time.

Had heard amazing things from my practitioner about their products. Had my account set up by them in less than one hour and the products delivered to my door just two days later. - Awesome!!

I was curious about Theralac, and when I inquired about the product, the owner said he would send me a sample. He sent me an entire bottle of Theralac without charge! Theralac has been a game changer for me! It took away the my severe digestive symptoms immediately, and has been a life-saver ever since! I have since shared my experience with many friends and associates. My next door neighbor tried a few of my capsules and loved them also. She has purchased several bottles for herself and her daughter.
