Puravita 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 energy metabolism, neuromuscular function, cardiovascular health, and more. Yet emerging evidence confirms that nearly two-thirds of the Western population does not achieve the recommended daily allowance — a gap that contributes to a range of health concerns.

Magnesium Complex from Nature's Sunshine was designed to help close that gap. Each serving of two capsules delivers 184 mg of Magnesium from two organic, highly soluble forms — Magnesium citrate and Magnesium malate — chosen specifically for their superior bioavailability compared to common inorganic forms like Magnesium oxide. This puravita Magnesium Complex focuses on the areas where research suggests Magnesium matters most: the heart, the brain and nervous system, and the kidneys.

If you have questions about whether a Magnesium supplement fits your personal wellness picture, our naturopath is available for a free consultation — no purchase necessary.

Not all Magnesium supplements are created equal. Organic forms — where Magnesium is chelated to organic molecules like citric acid or malic acid — are generally more soluble and have higher bioavailability than inorganic forms. Research shows that Magnesium citrate has high solubility even in water (55%) and is substantially more soluble than Magnesium oxide in all states of acid secretion. Magnesium malate likewise belongs to the organic category, offering efficient absorption.

By combining both citrate and malate in a single formula, this puravita Magnesium Complex provides two well-absorbed pathways for your body to take in this essential mineral. The result is a supplement that is not only highly soluble but also gentle enough for everyday use.

Cardiovascular System

Research suggests that Magnesium supports cardiovascular health through several mechanisms. It regulates cardiac ion channels, myocardial conduction, and vascular tone. Multiple meta-analyses and prospective cohort studies consistently associate higher Magnesium levels with lower risks of coronary heart disease, atrial fibrillation, and heart failure. A 2021 systematic review of 49 clinical trials confirmed antihypertensive effects of Magnesium supplementation, particularly in individuals who are Magnesium-deficient. Magnesium also participates in vascular calcification prevention and may improve flow-mediated dilation, supporting healthy arterial function.

In 2022, the U.S. FDA approved a qualified health claim stating that consuming diets with adequate Magnesium may reduce the risk of high blood pressure, though the agency notes the evidence is inconsistent and inconclusive.

Nervous System

Magnesium is fundamental to nervous system function. It acts as a physiological NMDA receptor antagonist, helping regulate neuronal excitability, neuromuscular transmission, and nerve signaling. Studies suggest that adequate Magnesium levels support neurotransmitter balance, including its role as a cofactor in dopamine synthesis and as a blocker of excessive glutamate receptor activity. Magnesium deficiency is clinically associated with neuromuscular hyperexcitability, tremors, and increased risk of neurological symptoms ranging from migraines to mood disturbances.

Kidney Health

The kidneys are the primary regulators of whole-body Magnesium homeostasis. Research suggests that Magnesium is a well-established inhibitor of calcium oxalate crystallization in urine. In a landmark double-blind RCT lasting up to three years, new kidney stones formed in only 12.9% of subjects receiving potassium-Magnesium citrate compared to 63.6% on placebo. Magnesium supplementation also reduces urinary oxalate excretion and raises urinary citrate — both key protective factors against stone formation.

Because an estimated 56–68% of Americans do not obtain enough Magnesium daily to meet the recommended dietary allowance, a wide range of people may benefit from supplementation. This puravita Magnesium Complex may be especially worth considering if you fall into one of these groups:

• Adults concerned about heart health — research consistently associates adequate Magnesium levels with cardiovascular support.
• Those looking to support nervous system function — Magnesium's role as an NMDA receptor antagonist is well documented in the scientific literature.
• People interested in kidney and urinary mineral balance — clinical trials suggest Magnesium citrate may help inhibit calcium oxalate stone formation.
• Older adults — Magnesium absorption and retention can decrease with age, and men over 70 and teenage girls are among the most likely to have low intakes.
• Individuals on certain medications — loop and thiazide diuretics, proton pump inhibitors, and certain antibiotics can deplete or interact with Magnesium status.

If you're unsure whether Magnesium supplementation is right for you — particularly if you take prescription medications — our naturopath can walk you through the details in a free consultation.

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

Because Magnesium can form insoluble complexes with certain medications — including bisphosphonates, tetracycline antibiotics, quinolone antibiotics, and gabapentin — it is important to separate intake. Bisphosphonates should be taken at least 2 hours apart from Magnesium, and antibiotics should be taken at least 2 hours before or 4–6 hours after Magnesium. As always, consult your healthcare provider if you are taking any medications.
