I've been taking this product once daily for the last two weeks, and looking for signs of improved health, especially in bowel function. I was already healthy in that regard, but I do think that my stools are more well-formed and non-messy. I've had almost no need for toilet paper the last 5 days, which is unusual. I've been looking for more fecal "floating", which I heard was an indication of good Bifido. Though I have not yet seen a clear difference, there is some suggestion of increased floating. Perhaps two weeks is not sufficient time to see a significant difference, but I'm not disappointed thus far. I could imagine that a elderly nursing home patient, for example, or someone with colonic dysfunction, might see more significant improvement.
