Electrolyte balance, muscle function, nerve function
Adults with active lifestyles or those with low dietary intake of magnesium- and potassium-rich foods.
Take 2 capsules once daily with 8–12 oz of water, preferably with food if you have a sensitive stomach.
Non-GMO; Gluten-free.
Magnesium acts as a cofactor for enzymes involved in energy production and muscle and nerve function, and magnesium citrate provides a well-absorbed form to support normal electrolyte balance.
Caution: May cause loose stools in some people; take with food and reduce dose if stomach upset occurs.
Potassium is the main intracellular electrolyte that helps regulate fluid balance and supports normal nerve signalling and muscle contraction.
Caution: High potassium intake may be unsuitable with certain medicines or low kidney function; check compatibility if you use potassium-sparing products.
Magnesium and potassium are key electrolytes that work together to support normal muscle and nerve function. Magnesium helps regulate channels that influence potassium movement in cells, while potassium maintains intracellular fluid balance and electrical activity.
Label Warning: For healthy adults aged 18 years and over. Consult a healthcare professional before use if pregnant, nursing, taking medication, or if you have a medical condition.
Who should be cautious: People with kidney concerns, heart rhythm concerns, or those on medications that may affect potassium or magnesium balance may need extra caution. Magnesium may reduce absorption of certain antibiotics and some medications when taken together; consider spacing doses. People on diuretics, ACE inhibitors, ARBs, or potassium-sparing medicines may need medical advice due to potassium content. Discuss with a healthcare provider before combining with medications that may interact.
Storage: Store in a cool, dry place.
