Top Nurex Magnesium Complex | Heart, Brain & Kidney

Magnesium is the fourth most abundant cation in the human body and a critical cofactor in more than 300 enzyme systems that regulate everything from energy production and nerve signaling to blood pressure and heart rhythm. Despite its essential roles, an estimated 56–68% of Americans do not obtain enough Magnesium from their daily diet to meet the Recommended Dietary Allowance. That widespread shortfall is why a well-formulated Magnesium supplement matters.

Our top nurex Magnesium Complex — Nature's Sunshine Magnesium Complex — delivers 184 mg of Magnesium per two-capsule serving through two organic, highly soluble forms: Magnesium citrate and Magnesium malate. Organic forms like citrate and malate are chelated to organic acids, giving them generally higher solubility and bioavailability compared to inorganic forms such as Magnesium oxide. Magnesium citrate in particular has been shown to have high solubility even in water (55%) and is substantially more soluble than Magnesium oxide in all states of acid secretion.

This dual-form approach is designed to support your cardiovascular system, brain and nervous system, and kidney health — the three pillars this formula is built around. If you have questions about whether a Magnesium supplement is right for your specific needs, our naturopath is available for a free consultation to help guide you.

Not all Magnesium supplements are created equal. The form of Magnesium determines how well your body can actually absorb and use the mineral. Magnesium supplements are broadly categorized into organic compounds (citrate, malate, glycinate, lactate) and inorganic compounds (oxide, sulfate, chloride). Organic forms involve Magnesium chelated to organic molecules such as organic acids, and they are generally more soluble with higher bioavailability.

This top nurex Magnesium Complex pairs Magnesium citrate and Magnesium malate — both organic forms — for optimum effectiveness. Magnesium citrate is recognized as one of the most bioavailable supplemental forms, with research demonstrating its high solubility in water and efficient absorption. Magnesium malate shares the favorable absorption profile of organic Magnesium salts. Together, these two forms help ensure the Magnesium you take actually reaches the cells that need it most.

Once absorbed, the Mg²⁺ ion goes to work as a cofactor in hundreds of enzymatic reactions. It is required for ATP synthesis — the fundamental energy currency of every cell — and plays a pivotal role in ion transport through the Na,K-ATPase pump. It modulates neuronal excitability through NMDA receptor blockade and voltage-gated calcium antagonism. And it participates in the regulation of vascular tone, cardiac electrophysiology, and inflammatory pathways.

Because Magnesium plays such a foundational role across so many body systems, a wide range of people may find this top nurex Magnesium Complex helpful. Certain groups are more likely than others to have Magnesium inadequacy, including:

• Older adults — As we age, Magnesium absorption and retention can decrease. Older people are more susceptible to deficiency due to decreased absorption from food, increased medication use (diuretics can deplete Magnesium), and potential dietary restrictions. Men older than 70 are among the most likely to have low intakes.
• People taking certain medications — Loop and thiazide diuretics deplete Magnesium through increased urinary excretion. Proton pump inhibitors (PPIs), when taken for prolonged periods (typically more than a year), can also cause hypomagnesemia.
• Individuals with type 2 diabetes — Studies have demonstrated that diabetes is often accompanied by lower Magnesium status, and Magnesium deficiency may contribute to insulin resistance.
• Those focused on heart health — Chronic Magnesium deficiency has been associated with increased risk of cardiovascular disease, and research suggests adequate Magnesium supports healthy blood pressure, arterial flexibility, and heart rhythm.
• Anyone concerned about kidney stone risk — Research suggests Magnesium is a well-established inhibitor of calcium oxalate crystallization in urine, and supplementation may reduce urinary oxalate excretion while raising protective urinary citrate levels.

Early signs of Magnesium deficiency can include loss of appetite, nausea, fatigue, and weakness. As deficiency worsens, numbness, tingling, muscle cramps, and abnormal heart rhythms may occur. If you recognize any of these patterns, consider scheduling a free consultation with our naturopath to discuss whether Magnesium supplementation makes sense for you.

Take 2 capsules twice daily with a meal. Each bottle contains 100 capsules.

Two capsules of Magnesium Complex contain 184 mg of Magnesium. For reference, the Recommended Dietary Allowance (RDA) for Magnesium is 400–420 mg/day for adult men and 310–320 mg/day for adult women. This supplement is intended to complement the Magnesium you already get from foods like green leafy vegetables, nuts, seeds, whole grains, and legumes.

Important safety note: Magnesium supplements can interact with several types of medications. If you take bisphosphonates, tetracycline or quinolone antibiotics, diuretics, proton pump inhibitors, or gabapentin, be sure to separate your doses appropriately — generally at least 2 hours for bisphosphonates, and at least 2 hours before or 4–6 hours after for antibiotics. Magnesium may reduce the absorption of gabapentin by 20%. As always, consult your healthcare provider before starting any supplement, especially if you have kidney concerns, as excess Magnesium is cleared through the kidneys.
