Frequently Asked Questions (FAQs)

1. Can you take magnesium and potassium supplements together?

Magnesium administration, concomitant with potassium, assists tissue replenishment of potassium. Therefore, we hypothesized that combinations of these cations would lower blood pressure.

2. What is potassium magnesium good for?

Magnesium and potassium are essential to support already healthy blood pressure. However, the intake of these two minerals from your usual diet is often insufficient. So we've created a magnesium/potassium supplement that promotes cardiovascular health and helps maintain already-healthy blood pressure levels.

3. Do you have to give magnesium with potassium?

Concomitant magnesium deficiency has long been appreciated to aggravate hypokalemia. Hypokalemia associated with magnesium deficiency is often refractory to treatment with K+. Co-administration of magnesium is essential for correcting the hypokalemia.

4. Does magnesium boost potassium?

It is concluded that the magnesium infusions significantly influence serum levels of potassium and calcium by changes in the renal threshold for tubular reabsorption.
