Magnesium Spray Alternative: Oral Magnesium Tablets

Exploring Magnesium spray and how oral Magnesium supports nervous system health, bone density, and muscle cramps. Learn about Nature's Sunshine Magnesium.

Understanding Magnesium

What Is Magnesium and Why Does It Matter?

If you've been researching a Magnesium spray, you're likely looking for a convenient way to get more of this essential mineral into your daily routine. 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. It is naturally present in many foods, yet research confirms that an estimated 56 to 68 percent of Americans do not obtain enough Magnesium in their diet to meet the recommended daily allowance.

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. Whether you've been considering a Magnesium spray or an oral supplement, the goal is the same: ensuring your body has what it needs to function at its best.

This formula 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. Calcium and Magnesium are nutritional partners and work best when taken together, which is why this formula also includes Calcium and Phosphorus.

How It Works

How Magnesium Supports Your Body

Magnesium plays an indispensable role in cellular energy generation. The MgÂČâș ion plays a pivotal role in ATP synthesis—the molecule your body uses to store and release energy. Without adequate Magnesium, energy production at the cellular level may be compromised, which can contribute to fatigue and weakness.

For your nervous system, Magnesium modulates neuronal excitability through voltage-gated Calcium antagonism and N-methyl-D-aspartate (NMDA) receptor blockade. This means it helps regulate nerve signaling, supporting calm, balanced neurological function. Deficiency is associated with increased risk of neurological symptoms including numbness, tingling, and muscle contractions.

Magnesium is also involved in bone formation, influencing the activities of osteoblasts and osteoclasts. It affects the concentrations of both parathyroid hormone and the active form of vitamin D—two 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 reduce the risk of bone fractures.

As a muscle relaxant, Magnesium is essential for both skeletal and smooth muscle contraction and relaxation. Magnesium deficiency impairs muscle relaxation—muscles may contract normally but struggle to fully release when levels are low. Early signs of deficiency include muscle cramps, fatigue, and weakness.

Key Ingredients

Magnesium — 250 mg
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. Research suggests that Magnesium is an essential cofactor in bone mineral metabolism, and observational data from large cohort studies have found higher Magnesium intake associated with 2–3% greater bone density in women. It acts as a natural NMDA receptor antagonist, modulating synaptic transmission and neuronal excitability, supporting normal nerve function. Studies suggest Magnesium supplementation may reduce muscle soreness, improve performance and recovery, and exert a protective effect on muscle damage in physically active individuals. A 2022 meta-analysis of 17 RCTs found that Magnesium supplementation significantly decreased serum C-reactive protein (CRP) and increased nitric oxide levels, suggesting a role in supporting healthy inflammatory response.
Calcium — 40 mg
Calcium is the most abundant mineral in the human body, with more than 99% stored in bones as hydroxyapatite. It provides skeletal strength and serves as a reservoir for Calcium to be released into the serum. Research suggests that Calcium is the primary mineral constituent of bone and the most extensively studied supplement for bone density. Meta-analyses of RCTs demonstrate that Calcium supplementation significantly improves bone mineral density, particularly in people under 35 building peak bone mass. Calcium is also essential for muscle contraction and relaxation—hypocalcemia is recognized as a cause of muscle cramps, tetany, and spasms. Calcium ions play a key role in nervous system function, stabilizing membrane potential and controlling the excitability of neurons.
Phosphorus — 30 mg
Phosphorus is the second most abundant mineral in the human body, with approximately 85% residing in bones and teeth forming hydroxyapatite alongside Calcium for structural integrity. It functions in critical pathways to produce and store energy in phosphate bonds (ATP), buffer blood, regulate gene transcription, and activate enzyme catalysis. Phospholipids—which contain Phosphorus as an essential structural element—are the primary components of neuronal cell membranes and are required for synaptic neurotransmission. Phosphorus also regulates the normal function of nerves and muscles, including the heart, and helps the body make protein for the growth, maintenance, and repair of cells and tissues.
Kelp Leaf and Stem
Kelp is a form of brown algae that has been used traditionally for centuries in East Asian, Indigenous, and European cultures. It is a rich source of vitamins and minerals, including iodine, Calcium, iron, and potassium. The main groups of biologically active compounds in Kelp are polysaccharides (including alginic acid, laminarin, and fucoidan) and minerals. Research suggests that the polysaccharide laminarin has antioxidant and immunomodulatory properties, while alginates are soluble dietary fibers that may support glycemic health. Kelp has traditionally been used to support thyroid and glandular health.
Licorice root
Licorice root (Glycyrrhiza glabra) has been used worldwide as a medicine for over 4,000 years, with records dating back to the Assyrian Herbal (2000 BC) and the Ebers Papyrus (1600 BC). It was traditionally used for coughing, asthma, wound healing, and diseases of the lungs, liver, and arteries. In Traditional Chinese Medicine, licorice appears in approximately 60% of prescriptions. The main constituent is glycyrrhizin, a triterpenoid saponin. Licorice root has traditionally been used to support gastrointestinal health, and the German Commission E approves its use for catarrhal conditions of the upper respiratory tract.
Peppermint Leaves
Peppermint (Mentha × piperita) is a hybrid mint that has been used as a remedy for indigestion since ancient Egyptian times. Its main constituents are menthol (approximately 40%) and menthone (approximately 23%). Menthol blocks Calcium channels in smooth muscle, producing antispasmodic effects on the gastrointestinal tract. The German Commission E approved Peppermint leaf for spastic complaints of the gastrointestinal tract. Traditionally, Peppermint has been valued for its carminative and digestive properties, and it has a long history of use for stomach soothing across Greek, Roman, and Arab traditions.
White willow Bark
White willow (Salix alba) has a medicinal history spanning more than 3,500 years—Sumerians, Egyptians, and Hippocrates used willow bark for pain and fever. The characteristic constituents are salicylate derivatives, primarily salicin, which is metabolized to salicylic acid in the body. The multi-component active principle of willow bark, which includes polyphenols, flavonoids, and condensed tannins, provides a broader mechanism than salicin alone. White willow bark has been traditionally used for discomfort, fever, and general aches, and the European Medicines Agency recognizes willow bark preparations under a traditional-use framework for short-term relief.

Who Benefits

Who May Benefit from Magnesium Supplementation?

Many people searching for a Magnesium spray are looking for relief from muscle cramps, better nervous system support, or help maintaining healthy bones. This oral Magnesium formula addresses all three of these areas.

Adults who may not be getting enough Magnesium through diet alone could benefit. The diets of most people in the United States provide less than the recommended amounts of Magnesium, and men older than 70 and teenage girls are most likely to have low intakes. As we age, Magnesium absorption and retention can decrease, leading to deficiency and health consequences.

Individuals experiencing occasional muscle cramps or tension may find Magnesium particularly relevant. Magnesium deficiency impairs muscle relaxation, and research suggests it plays a role in normal muscle contraction and recovery. Those focused on maintaining bone density may also appreciate the synergy of Magnesium, Calcium, and Phosphorus working together in this formula.

If you're uncertain whether Magnesium is right for your needs, our naturopath is available for a free consultation to help guide your decision.
