Pharma Mag Forte contains a combination of magnesium chelates to provide nutritional support for muscle function, as well as maintaining healthy muscle contraction and relaxation. Magnesium maintains cardiovascular system health and supports blood vessel health and dilation. Magnesium also supports nervous system function including nerve conduction and healthy neuromuscular system function.

• Magnesium (as magnesium orotate dihydrate) 30 mg
• Magnesium (magnesium aspartate) 21 mg
• Potassium (as potassium aspartate monohydrate) 50 mg
• Calcium (as calcium orotate) 10 mg
• Calcium (as calcium hydrogen phosphate dihydrate) 34 mg

Adults: Take 2 tablets two times a day, or as professionally prescribed.

Contains 50 mg of potassium per tablet.

Magnesium taken in high doses may cause loose stools.

Magnesium supplementation should be done cautiously in people with compromised renal function and is contraindicated in renal failure and heart block.

Concomitant use of aminoglycoside antibiotics and magnesium can increase the risk for neuromuscular weakness.

Calcium supplements can have an antagonistic effect on the action of calcium channel blockers.

Concurrent administration of levothyroxine and calcium may reduce drug absorption; separate doses by at least 4 hours.

Concurrent administration of quinolone antibiotics and calcium may reduce drug efficacy; take quinolones either 2 hours before or 4-6 hours after calcium.

Concurrent administration of tetracycline antibiotics and calcium may reduce drug efficacy; separate doses by at least 2 hours.

Calcium can interact with numerous drugs and should be used with caution by people with renal disease or hyperparathyroid conditions.

Caution with potassium in patients with renal insufficiency.

ACE inhibitors may produce hyperkalaemia when used in combination with potassium supplements.

Beta-adrenergic blockers may elevate potassium levels; caution use with potassium containing supplements.

Cyclosporine and heparin may produce hyperkalaemia due to decreased potassium excretion; caution use with potassium containing supplements.

Concomitant use of potassium-sparing diuretics with potassium containing supplements increases the risk of hyperkalaemia.
