I have been using this probiotic complex for almost 2 years. I hope it becomes available soon. I have been using probiotics for almost 20 years. This is my favorite. I don't always have the stomach for eating yogurt or drinking Kefir every day. I have a sensitive stomach and many allergies. This probiotic really helps with both. This product not only has 6 strands of Lactobacillus, and 2 of Bifidobacterium but fiber to feed them, and FOS a prebiotic. I read the other review saying it doesn't contain any probiotics and I simply have not found that to be true. I feel the same benefits if I'm drinking Kefir every day or taking this supplement, and if I haven't been doing either I have the same negative experiences. I love it and highly recommend it. Beware though it does contain milk thistle and I know some people have problems with that.
