Magnesium Hydroxide Guide | Caring Sunshine

Magnesium is the fourth most abundant cation in the human body and a critical cofactor in hundreds of enzymatic reactions that regulate energy metabolism, neuromuscular function, cardiovascular health, bone integrity, and psychological well-being. It is naturally present in many foods, including green leafy vegetables, nuts, seeds, whole grains, fish, and dairy products.

Nature's Sunshine Magnesium provides nervous system support and assists in a variety of bodily functions. Used by several hundred enzymes in their daily tasks, Magnesium is found in the bones, soft tissues, and blood. It helps metabolize various nutrients such as vitamin C, Phosphorus, potassium, and sodium.

Despite its essential roles, emerging evidence confirms that nearly two-thirds of the population in the western world is not achieving the recommended daily allowance for Magnesium — a deficiency problem contributing to various health conditions. Men older than 70 and teenage girls are most likely to have low intakes, and as we age, Magnesium absorption and retention can decrease, leading to deficiency and health consequences.

Calcium and Magnesium are nutritional partners and work best when taken together. Nature's Sunshine Magnesium comes in 250 mg capsules of Magnesium oxide and Magnesium amino acid chelate in a base of Licorice root, Kelp plant, Peppermint leaves, and White willow bark.

Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation. It is required for energy production, oxidative phosphorylation, and glycolysis.

At the skeletal level, Magnesium is involved in bone formation and influences the activities of osteoblasts and osteoclasts. It also affects the concentrations of both parathyroid hormone and the active form of vitamin D, which are major regulators of bone homeostasis. Research suggests that people with higher levels of Magnesium may have higher bone mineral density, which is important in helping support the risk reduction of bone fractures associated with osteoporosis.

In the nervous system, Magnesium modulates neuronal excitability through voltage-gated Calcium antagonism and N-methyl-D-aspartate (NMDA) receptor blockade. This makes it fundamental for normal nerve signaling and neuromuscular transmission.

For muscles, Magnesium deficiency impairs muscle relaxation — muscles contract normally but struggle to fully release when levels are low. A 2024 systematic review found Magnesium supplementation may reduce muscle soreness, improve performance and recovery, and exert a protective effect on muscle damage in physically active individuals.

This formula may be a good fit for adults looking to support their nervous system, maintain healthy bone density, or promote healthy muscle function. Since Magnesium is necessary for the function of over 300 enzymes, its benefits reach across multiple body systems — from energy production to proper elimination.

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.

It is estimated that between 56 and 68% of Americans do not obtain enough Magnesium in their diet to meet the recommended daily allowance. Early signs and symptoms of deficiency include loss of appetite, nausea, fatigue, and weakness. As deficiency worsens, numbness, tingling, muscle cramps, and abnormal heart rhythms can occur.

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

Take 1 tablet daily with a meal.

Each bottle contains 180 tablets. Calcium and Magnesium are nutritional partners and work best when taken together — this formula conveniently includes both minerals. Vitamin D also helps the body better absorb Calcium, so ensuring adequate vitamin D intake alongside this supplement may further support its benefits.
