Is Magnesium Complex Good for You? | Guide

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, bone integrity, and psychological well-being. Yet research suggests that between 56 and 68% of Americans do not obtain enough Magnesium in their diet on a daily basis to meet the recommended daily allowance.

If you've been wondering whether a Magnesium Complex is good for you, the answer depends on your current intake, your health goals, and the forms of Magnesium you choose. Nature's Sunshine Magnesium Complex pairs two highly soluble organic forms — Magnesium citrate and Magnesium malate — to support your cardiovascular system, nervous system, and bone density. Two capsules deliver 184 mg of Magnesium, and the product comes in a bottle of 100 capsules.

Because Magnesium is involved in everything from ATP energy production to nerve signaling to bone formation, understanding what a quality Magnesium Complex can do is well worth your time.

Not all Magnesium supplements are created equal. The form of Magnesium determines how well your body can absorb and use it. Organic forms — where Magnesium is chelated to organic molecules like organic acids — are generally more soluble and have higher bioavailability than inorganic forms such as Magnesium oxide.

Magnesium citrate is one of the most bioavailable forms available. Research shows it has high solubility even in water (55%) and is substantially more soluble than Magnesium oxide in all states of acid secretion. This means your body can absorb it efficiently regardless of your stomach-acid levels.

Magnesium malate, another organic form, shares these solubility advantages. By combining both citrate and malate in one formula, Magnesium Complex provides two complementary absorption pathways, helping ensure that the Magnesium you take actually reaches the cells that need it.

This is especially important because Magnesium is required for ATP synthesis — the fundamental energy currency of every cell — and serves as an essential cofactor for enzymatic ATP hydrolysis in the Na,K-ATPase pump that maintains cellular ion balance.

Given that the diets of most people in the United States provide less than the recommended amounts of Magnesium, a broad range of adults may benefit from supplementation. The RDA for adult men is 400–420 mg/day, while for adult women it is 310–320 mg/day — and many people fall short.

Older adults are especially susceptible to Magnesium deficiency due to decreased absorption from food, increased medication use (certain diuretics can deplete Magnesium), and potential dietary restrictions. Men older than 70 and teenage girls are among those most likely to have low intakes.

People focused on heart health may find Magnesium Complex particularly relevant. Research suggests that higher Magnesium levels are inversely associated with risks of coronary heart disease, stroke, and total cardiovascular disease. In 2022, the FDA approved a qualified health claim stating that consuming diets with adequate Magnesium may reduce the risk of high blood pressure, though the agency noted the evidence is inconsistent and inconclusive.

Those concerned about bone density should know that Magnesium is involved in bone formation, influences osteoblast and osteoclast activity, and affects concentrations of both parathyroid hormone and the active form of vitamin D. People with higher Magnesium levels may have higher bone mineral density.

Individuals taking certain medications — including loop and thiazide diuretics, proton pump inhibitors (PPIs) taken for more than a year, or bisphosphonates — may experience Magnesium depletion and could benefit from supplementation, though timing of doses is important (see our FAQ below).

Other groups at elevated risk of Magnesium inadequacy include individuals with gastrointestinal disorders, those with type 2 diabetes, and people with alcohol dependence. If you're unsure whether Magnesium supplementation is right for you, our naturopath can help you think through your situation during a free consultation.

Take 2 capsules twice daily with a meal. Each serving of 2 capsules provides 184 mg of Magnesium from both citrate and malate forms.

Taking Magnesium with food may help support absorption and reduce the likelihood of stomach-related side effects, which are the most common adverse reactions and tend to occur more frequently at higher doses or with inorganic forms like Magnesium oxide.

Important timing note: If you take bisphosphonates such as alendronate, separate your Magnesium dose by at least 2 hours. If you take tetracycline or quinolone antibiotics, the antibiotic should be taken at least 2 hours before or 4–6 hours after Magnesium. Magnesium may also reduce the absorption of gabapentin by about 20%. Always consult your healthcare provider if you are on medications.
