They are both wonderful for liver support. I used to take some when I was potassium deficient and my liver was struggling.
I am no expert, but I believe you should take one OR the other. The two at once 3 times a day is a bit too much. When your body has a mineral in excess it then tends to poorly absord some other minerals. If you want to use both, use one once/day and the other twice.
I used it when I had an upper back shoulder pain. If you have such a pain you should carry on until the pain is over and carry on perhaps a 4 to 6 weeks after. If you do not have such a pain. After 3 weeks, you whould definitely slow down for the reason above, it will interfere with the absorption of other minerals. You might want to carry on once a day, if you still feel taht your liver is not up to it.
