This was one of several probiotics which I have sampled over the last couple of years. It is one which I would recommend. I have found that regular use of such products has helped to improve my digestion and the general well being of my gut. This particular product would rate as one of the better examples. I have tended to find that similarly high quality probiotics have the best results. I now have three products from three different sources which I would recommend and buy which ever is on offer. This is one of them!
