Can't live without these.
I recently ran out and had to wait a few days before my order arrived. My stomach was miserable for days. The day after I got back on schedule I was back to normal. It's pricey but there is no denying that it makes my life a whole lot better.

Seems to be Effective, I may need a higher dose
Even though I am extremely sensitive to prebiotics, I tolerate the inulin in this plus the bacteria can grow.

Damaged bottle
The bottle arrived with the cap broken and says it needs to be refrigerated in the small print on the bottle but didn’t ship with a cold pack. Now I need to see about getting an exchange but my doctor really wanted me to be taking these a while ago so this is prolonging my treatment plan.

Probiotics work
Only reason I gave this a 3 was because it took way too long for them to arrive and they are supposed to be in a cold bag, hard to believe they are any good right now when it took over 10 days to get to me.
