Know you did not tag me but will pass on what my EP at Mayo Jacksonville told me.

Magnesium comes in a lot of different forms and each has a different added benefit. I was told to take 400 mg of Magnesium Citrate by my EP for PVCs. Why? He stated was the most absorbable.

Some individuals take the citrate to help with bowel movements as magnesium help bring water into intestines (EP not me). So some can have an increase in loose bowels when taking citrate. I was told if that was the case (again my EP) to take the glycinate as second best absorbed form. I have been taking 400 mg of citrate for over 2 years now. And yes did help with my PVCs along with some additional medication ordered for me recently.

My post and type of magnesium are not from "my view" but directly the information from my Mayo EP.
