If you’re considering boosting your magnesium levels, you’ve probably thought about adding a magnesium body spray to your routine. It’s easy to see why—these sprays promise easier sleep and reduced stress with just a quick spritz, making them as appealing as other wellness trends like ear seeding for cortisol balance.
Magnesium body sprays are topical products that deliver magnesium through the skin, aiming to relax muscles, improve sleep, and promote overall calm. “They’re marketed as an alternative to oral supplements for raising magnesium levels,” explains Krupa Koestline, a cosmetic chemist and founder of KKT Labs.
She notes that these sprays typically contain magnesium chloride hexahydrate, often labeled as “magnesium oil,” dissolved in water. Most formulas use a 20 to 35% magnesium chloride solution, and some include moisturizers like glycerin to counter potential dryness or stickiness.
Magnesium deficiency is common, affecting between 2.5% and 15% of people in the U.S. Dr. Amanda Kahn, an internist and longevity specialist, points to modern diets low in magnesium-rich foods, chronic stress, and certain medications like birth control as contributing factors. This is where magnesium sprays claim to help—but do they really improve sleep?
Do They Work?
Yes, but only to a degree. Dr. Kahn explains that while some magnesium can be absorbed through the skin, the absorption rate is inconsistent, making it hard to confirm if it works as advertised. The skin acts as a strong barrier, and Koestline adds that magnesium ions are relatively large and hydrated, which limits their ability to penetrate deeply. Small studies suggest topical magnesium can raise levels in the outer skin layer, but more research is needed to compare it with oral supplements.
“From a scientific perspective, these sprays act more like mineral salt sprays with local effects—such as cooling and soothing—rather than a reliable way to deliver magnesium throughout the body,” says Koestline.
How to Use Magnesium Spray Effectively
You don’t need to avoid magnesium sprays altogether. Instead, use them alongside oral magnesium supplements. “Sprays are a helpful addition, not a replacement,” Koestline advises. “I recommend oral magnesium as your main source and using sprays for extra muscle relaxation or as part of a calming bedtime routine.”
For best results, apply the spray to clean skin—ideally after a shower when pores are more open—and focus on areas with thin skin or good blood flow, like the inner arms, behind the knees, or the tops of the feet. Start with a few sprays to get used to any tingling from the magnesium chloride, then gradually increase as needed.
If you’re using it for better sleep, Dr. Kahn suggests applying 10 to 15 sprays to your legs or feet and letting it dry for 20 minutes before bed. For muscle cramps, spray the affected area as required. Be cautious if you have sensitive skin, as irritation, itching, or stinging may occur—always do a patch test first.
There are many options available, such as the Alo Magnesium Reset Spray or the HigherDose Magnesium Spray for Muscle Recovery, which can be helpful after a tough workout. Remember, consistency is key to seeing results. “Use it regularly,” Koestline emphasizes.Just like many wellness routines, you’re likely to see better results with consistent practice.
