Life Extension Potassium with Extended-Release Magnesium provides, per vegetable capsule, 250 mg of magnesium (67% of the NRV) — from ZümXR® extended-release magnesium oxide and magnesium citrate — and 99 mg of potassium (as potassium chloride; 5% of the NRV).
Magnesium contributes to normal muscle function and normal functioning of the nervous system, to electrolyte balance and to the reduction of tiredness and fatigue. Magnesium also contributes to normal energy-yielding metabolism and to the maintenance of normal bones.
ZümXR® technology was designed by the manufacturer to release magnesium gradually over several hours rather than all at once. Potassium is a mineral found naturally in fruit, vegetables, pulses and nuts.
60 vegetable capsules — 60 servings of 1 capsule.
Important: do not use without medical advice if you have kidney disease or take ACE inhibitors, ARBs or potassium-sparing diuretics.
Take 1 capsule per day with water. The manufacturer indicates 1 capsule once or twice a day; 2 capsules provide 500 mg of magnesium (above the EFSA tolerable upper intake level of 250 mg/day) and should only be taken with advice from a health professional.
Directions as indicated by the manufacturer Life Extension.

✔ Vegetable capsules
Magnesium contributes to normal muscle function and normal functioning of the nervous system, to electrolyte balance and to the reduction of tiredness and fatigue. Magnesium also contributes to normal energy-yielding metabolism and to the maintenance of normal bones. The amount of potassium per capsule (99 mg) is low — 5% of the NRV.
Take 1 capsule per day with water. The manufacturer indicates 1 capsule once or twice a day; 2 capsules provide 500 mg of magnesium, above the EFSA tolerable upper intake level of 250 mg/day, so only take them with advice from a health professional.
The magnesium is present as ZümXR® magnesium oxide, a technology designed by the manufacturer to release the mineral gradually over several hours rather than all at once.
People with kidney disease or who take ACE inhibitors, angiotensin II receptor blockers or potassium-sparing diuretics should not use it without medical advice. Pregnant or breastfeeding women and people taking medication should consult their doctor.
