A round yellow pill with "klor-con 10" printed on pill; I had trouble digesting the tablet. my potassium level would drop too low. Up to 6 to 8 pills, twice aday. Some of the pills would pass thru still intact, no wonder my potassium level was low. ATE foods in high potassium.Still low. Must have a very tough outer skin that I could not absorb. Now take Klor-con M 10,a long white pills, no tough skin, take 4 capsule twice aday along with food with high potassium and the Level is 4.2. I have CM.
