I have been taking magnesium for over 2 decades for back nerve damage and never experienced an issue or side effect. The vitamin also helps with chronic migraines that have been active since a surgery in 1995. Now that rheumatoid arthritis has started magnesium is helping with it.
The vitamin dose does what is necessary for the day in my body then disposes of the rest using the urine.
