Magnesium citrate 3 pastes a day. Try one paste on the first day, 2 on the second and so on. When you feel mild diarrhea, it is because your body has already reached the necessary limit and the rest is removed from the system. In my case, my limit is 3. When I took the 4th paste, my body expelled the surplus. Don't worry, it is impossible to have an overdose of magnesium since it is something natural in the body. If you have problems sleeping or problems digesting the last meal, take it 6 or hours later since the stomach system works better at that time. In my case I take it in the morning the first hour of the day. Buy my magnesium in natural stores, it is always better that it is only magnesium I'm sorry for my English
