I used a magnesium calcium zinc supplement and took as it said on the bottle. it was 2 dollars from a dollar store and it worked for me it takes about four days after being on it..in my experience. there are differnet magnesium..magnesium stearate and magnesium oxide..i just bought some magnesium oxide tonight...im not sure what the magnesium was for the first bottles i bought from the dolllar store, but this magnesium oxide i am trying is from walmart and is a once a day daily pill and is 250mg.
i had problems such as a lot of belching, and it was like hot acidity feeling burps that kept me awake at night...it would last up to an hour and i would feel very nauseas..after the first four days of taking magnesium it went away..when i stopped taking MG it came back..so i plan on taking it continuously
