Magnesium is a vital mineral that plays a crucial role in over 300 biochemical reactions in the body, affecting everything from muscle function and nerve transmission to energy production and bone health.

Yet despite its profound importance, many people do not get enough magnesium from their diets alone. Indeed, approximately 50% of Americans have insufficient magnesium levels, according to the Journal of the American Osteopathic Association, because of the popularity of processed foods high in fats, refined grains, sugars, and phosphates, which are low in magnesium content.

Widespread magnesium deficiency (as well as vitamin D deficiency) is unlikely to be confined to the US alone, with similar problems in other Western countries where most diets are woefully lacking in vegetables, nuts, seeds and other magnesium-rich foods.

Even short-term deficiency can lead to various health issues, including muscle cramps, fatigue and heart problems.

To increase you daily intake of this essential mineral make sure you eat more of the foods listed above, any you may also want to consider taking a form of magnesium supplement to boost your levels.

Two options have become incredibly popular over recent years: magnesium gummies, which offer a quick, tasty and convenient way to boost your intake; and magnesium sprays, a more direct form of supplementation because the nutrient is absorbed through the skin directly to the bloodstream where it can be transported around the body to where it’s needed.

Here’s what you need to know about the spray form of magnesium to decide whether it’s the best course of action to improve your overall health and wellbeing.

What is magnesium spray?

Magnesium spray is a topical solution designed to deliver magnesium directly through the skin. It typically consists of a mixture of magnesium chloride and water, creating a concentrated solution that can be easily absorbed when applied to the skin. This method of supplementation is thought to bypass the digestive system, allowing for more efficient absorption of magnesium directly into the bloodstream. Users often apply it to areas where muscle tension or cramps are common, such as the legs, back and shoulders

Why is magnesium important?

Magnesium is essential for maintaining several key bodily functions. It supports muscle and nerve function, helps regulate blood pressure, and contributes to the synthesis of proteins and DNA. Magnesium also plays a vital role in energy production and the maintenance of normal heart rhythm. Adequate magnesium intake is associated with a lower risk of conditions such as hypertension, cardiovascular disease and type-2 diabetes, according to the National Institutes of Health. Magnesium also helps to manage calcium levels in the body, ensuring proper bone formation and maintenance.

Do I need a magnesium spray?

Whether you need to use magnesium spray depends on your individual health needs and dietary intake. If you struggle to get enough magnesium through your diet or have specific conditions like muscle cramps, restless legs, or chronic fatigue, magnesium spray could be beneficial. It’s particularly useful for individuals with digestive issues that impair nutrient absorption. However, it’s always best to consult with a healthcare provider to determine if magnesium spray is right for you and to ensure you’re meeting your nutritional needs adequately.

How do magnesium sprays work?

Magnesium spray works by delivering magnesium directly through the skin. When sprayed onto the skin, magnesium chloride is absorbed into the epidermis and then transported into the bloodstream. This transdermal method is believed to be more efficient than oral supplementation for some individuals, especially those with digestive issues that hinder nutrient absorption. The direct absorption through the skin allows for a quicker and more targeted delivery of magnesium to areas where it is needed most, such as muscles and joints.

How do I use magnesium spray?

Using magnesium spray is straightforward. Simply spray the solution onto clean, dry skin and gently massage it in. It’s often recommended to apply the spray to areas with high muscle activity or where cramps and tension are frequent, such as the legs, back, and shoulders. Start with a few sprays and gradually increase the amount as needed. It’s normal to feel a slight tingling sensation upon application, which usually subsides after a few minutes. For best results, use magnesium spray daily or as directed by a healthcare professional.

Are there risks to using magnesium spray?

Magnesium spray is generally safe for most people when used as directed. However, some individuals may experience mild skin irritation, such as redness or itching, especially if they have sensitive skin. It’s advisable to do a patch test before using the spray extensively. Excessive use of magnesium spray could potentially lead to hypermagnesemia, a condition characterised by elevated magnesium levels in the blood, which can cause symptoms such as nausea, dizziness, and muscle weakness. Always follow the recommended dosage and consult a healthcare professional if you have any concerns.

Does the science support the health claims of magnesium spray?

There is some scientific evidence supporting the efficacy of magnesium spray for increasing magnesium levels and alleviating symptoms related to magnesium deficiency. A study published in the European Journal of Nutritional Health found that transdermal magnesium application significantly increased serum magnesium levels in participants. However, more research is needed to fully understand the benefits and optimal usage of magnesium spray compared to oral supplements. While anecdotal evidence is strong, it’s essential to rely on scientific research and consult healthcare professionals for personalised advice.

Where can I buy magnesium spray?

Sprays are widely available both online and in physical stores. You can purchase it from health food shops, pharmacies, and major retailers such as Amazon, Boots, and Holland & Barrett. Additionally, many specialty wellness stores offer high-quality magnesium sprays that may contain added ingredients for enhanced benefits, such as essential oils. When buying magnesium spray, look for reputable brands that provide clear information about the concentration of magnesium and ensure the product is free from harmful additives.
