Die off is what they mean. I experience severe die off when I took 3 packets a day and other probiotics to boot. I have cut back so I can feel better. You need to try it to understand it. Everyone is different when it comes to thier Candida and die off symptoms. Die off is just a flare up of the effects that Candid has on your system. When they little buggers die, they release toxins into your blood stream and such and hence you have die off symptoms. The symptoms are different for everyone. The only way to know is to go throgh it. You have to reach that limit and be able to taylor a treatment plan that wont continue to pull you down. The balance is great when you can function normally and the die off is tolerable. At least it is for me.
