Building Magnesium Levels, When to Test, and Maintenance Dosage

I would suggest that anyone wanting to supplement their magnesium to have their EXA levels tested first. If your magnesium is low, then follow the recommendations from the guide above. Depending on how low your level of stored magnesium is, is how long you should supplement magnesium to get optimal levels.

Length of Average Magnesium Supplementation 1

If your magnesium levels are normal, you should take a daily supplementation of elemental magnesium of about 400 – 600 mg daily. Even if your magnesium levels are normal, and you have a specific medical reason to increase your magnesium above these levels (chronic fatigue syndrome, nerve damage, and brain trauma are some examples), you should be fine to increase supplementation as long as you have adequate kidney function. You will need to get your magnesium levels frequently tested (every two – three months), to make sure hypermagnesemia does not occur.

Finally, if you magnesium levels are extremely low, IV magnesium supplementation might be needed on an emergency basis. 2


Hypermagnesemia is a rare condition in which a person has too much magnesium in their blood plasma. Hypermagnesemia usually happens in patients with poor kidney function and patients that receive an overdose of IV magnesium. Rarely, supplemental magnesium causes hypermagnesemia; this is because the kidneys are very good at excreting excess magnesium. 3

Diagnostic symptoms are usually a combination of low blood sugar and high calcium. Symptoms usually include weakness, vomiting, impaired breathing, hypotension, increased blood calcium levels, arrhythmia, lack of muscle reflexes, and bradycardia (slow heart rate). It is possible that if one’s plasma magnesium level is too high the heart can stop, causing a “heart attack” because magnesium is a muscle relaxant, but this outcome is extremely rare. 4

Treatment for hypermagnesemia includes giving IV calcium gluconate to inactivate and bind to the excess magnesium. The calcium also reactivates the muscle cells because calcium is a muscle stimulator. Finally, dialysis might be needed in some cases to eliminate excess magnesium and to help with kidney function. Fatality from hypermagnesemia is very low. 5
