Xtendlife's Marine Magnesium with Potassium - Your Vital Mineral Supplement
The minerals, magnesium and potassium, are crucial for your well-being. They're co-factors in over 300 bodily processes, including energy production, nerve function, muscle health, stress regulation, and sleep enhancement. Most adults aren't getting enough of either in their daily diet, and should consider supplements for optimal health.
Our researchers have carefully chosen Aquamin MG® – the most bioavailable form. Sourced from pure Irish seawater, it's rich in elemental magnesium and 72 trace elements, benefiting your health.
Our formula reduces stress hormones, promotes feel-good neurotransmitters, and regulates sleep by enhancing melatonin production.
Magnesium protects brain health, aids cognitive function, and safeguards against cognitive decline. It also supports heart health by regulating rhythm, blood pressure, and muscle function, reducing spasms and inflammation.
Our potassium supplement formula includes 110mg of elemental potassium to support cardiovascular health and synergy with magnesium.
Half of adults lack these essential minerals. At-risk groups include those with gastrointestinal diseases, type 2 diabetics, and older adults who struggle with the absorption of magnesium. Try our magnesium and potassium today and see the difference.
Fill the gap in your diet with Xtendlife's Marine Magnesium with Potassium. It's highly bioavailable, rich in elemental magnesium, potassium, and trace elements, ensuring your natural health. Say goodbye to deficiencies and hello to a healthier, more balanced you with our magnesium and potassium supplements.

If you are taking CX8 we do not recommend that you take CX8 and Marine Magnesium with Potassium at the same time. This is because Magnesium may affect the efficacy of the Vitamin K2 ingredient which is present in CX8. Take CX8 in the morning if possible, as this increases your energy and then take the Magnesium at bedtime as it helps with sleep.
If you are pregnant, lactating or taking any medications, please consult your health practitioner before starting new supplements.
