I take 400 mg of Citrate. My EP recommended the citrate as said is easily absorbed. He said that the Glycimate would be next as is also highly absorbable.

Some take magnesium to help with bowel movements as helps with fluids in bowels. However the citrate formula can issues for some as so easily absorb. I don't have this issue but we are all different. Make sure you check with your doctors if you are consuming a high intake of magnesium already in your food.
