Topical Magnesium Fights Stress, Boosts Sleep, and Enhances Recovery

If you've been looking for a way to boost your health without relying on pills or complex routines, topical magnesium chloride might just be the answer you’ve been searching for.

Today, I’m going to break down why magnesium chloride, when applied topically, may be a go-to tool for sleep, chronic pain, and nervous system health.

What Is Magnesium Chloride?

Magnesium chloride (MgCl₂) is a form of magnesium that’s well-known for its rapid absorption when applied to the skin. This makes it a highly effective option for individuals who might not respond well to oral supplements or want to avoid any potential digestive discomfort that magnesium pills sometimes cause. Magnesium is involved in over 300 biochemical reactions in the body, so its role is crucial. It helps with muscle function, bone health, energy production, and even nerve function. But when your magnesium levels are low, it can lead to a variety of issues—think fatigue, muscle cramps, and even sleep problems (1).

Does Topical Magnesium Work?

Topical magnesium–magnesium applied to the skin–has been shown to bypass the digestive system, delivering magnesium directly into the bloodstream via the skin. This can help people who have trouble absorbing magnesium through oral supplements or who want a more convenient, less invasive method of supplementation. However, there is no perfect mechanism for absorbing magnesium. Indeed, the quantity of magnesium which can be absorbed into the bloodstream via the skin is debatable (1).

Researchers looked at how topical magnesium cream affected serum and urinary magnesium levels in humans. What they found was promising—regular use of magnesium cream led to an increase in magnesium levels in the body without the laxative effect that oral magnesium supplements sometimes produce. This is important because magnesium deficiency is often overlooked but can contribute to everything from muscle weakness to mental fog and anxiety. (3).

Magnesium Spray for Nervous System Health?

One fascinating study explored the potential of magnesium chloride for treating peripheral neuropathy in individuals with chronic kidney disease (CKD). This condition, which can cause problems like tingling, numbness, or pain, especially in the hands and feet can be excruciating. The pilot study found that topical magnesium chloride was effective in reducing symptoms of nerve pain. Magnesium’s ability to calm overactive nerves and improve circulation may be useful for those suffering from conditions like these (2).

For those suffering from fibromyalgia, a chronic condition characterized by widespread pain, fatigue, and sleep disturbances, magnesium could offer some much-needed relief. A feasibility study found that applying magnesium chloride twice daily on the limbs resulted in significant improvements in quality of life for women with fibromyalgia. The study highlighted that transdermal magnesium reduced pain levels, improved sleep, and alleviated pain—a common symptom of fibromyalgia (4).

The Bottom Line: Is Topical Magnesium Right for You?

As you can see, the research points to a variety of potential health benefits when it comes to topical magnesium chloride, from reducing pain and inflammation to improving sleep and supporting nerve health. Although more research is needed to confirm these results in humans, topical magnesium may be a useful tool for whole-body health.

As with any new health strategy, it's always a good idea to consult with a healthcare provider to ensure it's a good fit for you.
