Magnesium Complex | Heart, Brain & Kidney Support

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 metabolism and neuromuscular function to cardiovascular health and bone integrity. Despite its importance, an estimated 56–68% of Americans do not obtain enough Magnesium from their diet to meet the recommended daily allowance.

Magnesium Complex delivers this essential mineral in two highly soluble organic forms — Magnesium citrate and Magnesium malate — chosen specifically for their superior bioavailability compared to inorganic forms like Magnesium oxide. Two capsules provide 184 mg of Magnesium to support the cardiovascular system, promote healthy brain and nervous system function, and help maintain kidney health.

Organic forms of Magnesium, such as citrate and malate, are chelated to organic acid molecules and are generally more soluble with higher bioavailability. Research confirms that Magnesium citrate has high solubility even in water (55%) and is substantially more soluble than Magnesium oxide across all states of acid secretion. This means the Magnesium in Magnesium Complex is well-positioned for efficient absorption.

Not all Magnesium supplements are created equal. The form of Magnesium determines how well your body can actually absorb and use it. Magnesium Complex pairs two organic forms — citrate and malate — that each bring distinct advantages.

Magnesium citrate is one of the most bioavailable supplemental forms available. Its high water solubility translates into efficient absorption in the digestive tract. Magnesium malate is another well-absorbed organic form, chelated to malic acid, that shares the same bioavailability advantages of organic Magnesium salts.

Once absorbed, the Mg²⁺ ion goes to work throughout the body. It plays a pivotal role in ATP synthesis — the energy currency of every cell — and is an essential cofactor for the Na/K-ATPase ion pump that maintains proper cellular electrical balance. In the heart, Magnesium regulates cardiac ion channels, myocardial conduction, and contraction. In the nervous system, it acts as a natural NMDA receptor antagonist, modulating neuronal excitability and synaptic transmission. In the kidneys, it supports the organ's role as the primary regulator of whole-body Magnesium homeostasis.

This multi-system reach is why adequate Magnesium status matters so much — and why getting it in well-absorbed forms makes a real difference.

Because Magnesium is involved in so many body systems, a broad range of people may benefit from supplementation — particularly those who struggle to get enough from diet alone. Certain groups are more likely than others to have Magnesium inadequacy, including older adults (due to decreased absorption), individuals with gastrointestinal disorders, those with type 2 diabetes, people with alcohol dependence, and individuals on certain long-term medications such as diuretics or proton pump inhibitors.

Men older than 70 and teenage girls are among the most likely to have low intakes of Magnesium. As we age, Magnesium absorption and retention can decrease, making supplementation increasingly relevant for supporting heart rhythm, nerve function, and bone health.

People focused on cardiovascular wellness may find Magnesium Complex particularly relevant, as research suggests adequate Magnesium supports healthy blood pressure, arterial flexibility, and normal heart rhythm. Those concerned about nervous system health — including anyone dealing with occasional muscle cramps, restless legs, or general nerve comfort — may also benefit from maintaining adequate Magnesium levels. And for kidney health, studies suggest Magnesium plays a role in inhibiting calcium oxalate crystallization in urine, supporting healthy urinary mineral balance.

If you're unsure whether Magnesium Complex is right for your individual needs, our naturopath is available for a free consultation to help you figure out the best approach.

Take 2 capsules twice daily with a meal.

Each bottle contains 100 capsules. Taking Magnesium with food helps support comfortable digestion and efficient absorption.

It's important to be aware that Magnesium may interact with certain medications. Magnesium can form insoluble complexes with tetracycline and quinolone antibiotics — these should be taken at least 2 hours before or 4–6 hours after Magnesium. Magnesium-rich supplements should also be separated from oral bisphosphonates by at least 2 hours. Loop and thiazide diuretics can deplete Magnesium through increased urinary excretion, while long-term proton pump inhibitor (PPI) use can cause low Magnesium levels. Magnesium may also reduce the absorption of gabapentin by approximately 20%. If you are taking any medications, consulting with a healthcare professional before starting supplementation is always a good idea.
