Nordic Magnesium Complex | Heart, Nerve & Bone

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 essential roles, an estimated 56–68% of Americans do not obtain enough Magnesium in their daily diet to meet the Recommended Dietary Allowance.

A well-designed nordic Magnesium Complex addresses this gap by combining two highly bioavailable organic forms of the mineral — Magnesium citrate and Magnesium malate — in a single capsule. Nature's Sunshine Magnesium Complex delivers 184 mg of Magnesium per two-capsule serving, using these organic salt forms that are generally more soluble and more readily absorbed than inorganic alternatives like Magnesium oxide. Research confirms that Magnesium citrate, for instance, has high solubility even in water (55%) and is substantially more soluble than Magnesium oxide in all states of acid secretion.

This dual-form nordic Magnesium Complex is formulated to support the cardiovascular system, help brain, kidney, and heart functions, and deliver Magnesium in a highly soluble format your body can actually use. If you have questions about whether Magnesium supplementation is right for you, our naturopath is available for a free consultation to help you explore your options.

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. This nordic Magnesium Complex pairs two such organic forms to support broad-spectrum mineral replenishment.

Cardiovascular Support

Magnesium plays a well-documented role in cardiovascular health. Research suggests that higher dietary and circulating Magnesium levels are inversely associated with risks of coronary heart disease, stroke, and total cardiovascular disease. Magnesium regulates cardiac ion channels, myocardial conduction, and contraction, and studies suggest that supplementation may produce modest but significant reductions in blood pressure, particularly in Magnesium-deficient or hypertensive individuals. A 24-week randomized controlled trial found that 350 mg/day of Magnesium citrate significantly reduced arterial stiffness as measured by pulse wave velocity.

Nervous System Support

Magnesium is fundamental to nervous system function, acting as a natural NMDA receptor antagonist that modulates synaptic transmission and neuronal excitability. This voltage-gated calcium antagonism and NMDA receptor blockade may help attenuate cortical spreading depression and trigeminovascular activation — mechanisms at the core of migraines. Deficiency is clinically associated with neuromuscular hyperexcitability, tremors, and neurological symptoms ranging from migraines to mood changes.

Bone Density Support

Magnesium is involved in bone formation and influences the activities of osteoblasts (bone-building cells) and osteoclasts (bone-resorbing cells). It also affects concentrations of both parathyroid hormone and the active form of vitamin D — two major regulators of bone homeostasis. Observational data from large cohort studies have found that higher Magnesium intake is associated with 2–3% greater bone density in women, and clinical trials suggest supplementation may help attenuate bone loss.

Given that an estimated 56–68% of Americans fall short of the recommended daily allowance for Magnesium, a wide range of people may benefit from a nordic Magnesium Complex. Certain populations face an elevated risk of deficiency: older adults (whose Magnesium absorption and retention tends to decrease with age), individuals with gastrointestinal disorders, those with type 2 diabetes, people with alcohol dependence, and anyone taking long-term medications such as diuretics or proton pump inhibitors that deplete Magnesium stores.

Men older than 70 and teenage girls are among the groups most likely to have low Magnesium intakes. Early signs of deficiency can include fatigue, weakness, loss of appetite, muscle cramps, and nausea. As deficiency worsens, more serious symptoms like numbness, tingling, abnormal heart rhythms, and personality changes may develop.

This formula may be particularly relevant for adults focused on cardiovascular wellness, those looking to support bone density as they age, or anyone who wants to promote healthy nervous system function. If you're taking medications or have specific health concerns, our naturopath can help you determine whether this nordic Magnesium Complex fits your individual wellness plan — that consultation is always free.

Take 2 capsules twice daily with a meal. Each two-capsule serving provides 184 mg of Magnesium from both Magnesium citrate and Magnesium malate. The bottle contains 100 capsules.

Taking Magnesium with food may help optimize absorption and reduce the likelihood of digestive discomfort, which is occasionally associated with Magnesium supplementation — particularly at higher doses. The most common side effects of supplemental Magnesium are stomach-related issues such as softened stool, nausea, or cramping, though these tend to be more prevalent with inorganic forms like Magnesium oxide rather than the organic citrate and malate forms used here.

Important interactions to be aware of: Magnesium may decrease the absorption of bisphosphonates (separate by at least 2 hours), and it can form insoluble complexes with tetracycline and quinolone antibiotics (take the antibiotic at least 2 hours before or 4–6 hours after Magnesium). Certain diuretics and proton pump inhibitors can deplete Magnesium. Magnesium may also reduce the absorption of gabapentin. If you take any prescription medications, we recommend speaking with a healthcare professional or scheduling a free consultation with our naturopath before starting supplementation.
