Magnesium oil spray may potentially help with pain relief and improved joint function. However, more research is necessary to support and understand the extent of these potential benefits.

Magnesium oil spray delivers magnesium using a transdermal route. Because it bypasses the gastrointestinal tract, some suggest that it may offer benefits with fewer side effects.

Many claims supporting magnesium oil spray are anecdotal. More scientific studies may be necessary to prove its potential.

A small pilot study of 20 people with chronic kidney disease involving peripheral neuropathy, a type of nerve damage that can cause pain, tested whether transdermal magnesium could relieve their peripheral neuropathy symptoms.

14 participants completed the study. After 8 and 12 weeks, the participants reported significant reductions in their symptoms. However, more research is necessary to replicate and understand these results.

A 2022 study suggests that magnesium pills led to perceived significant reductions in muscle soreness after exercising. However, the study did not use transdermal magnesium.

An older 2015 study found that applying magnesium spray to the limbs may help to improve symptoms in 25 people with fibromyalgia. Fibromyalgia is a condition that involves chronic pain among other symptoms.

More research is necessary to understand the full therapeutic potential of magnesium oil spray for pain relief.

A 2020 study suggests that transdermal magnesium oil may offer the following benefits to people with arthritis:

More research is necessary to investigate this potential benefit.

However, most research into magnesium’s benefits looks at magnesium supplementation rather than transdermal application.

People should consider how researchers use magnesium in their studies, as the various forms may not offer the same benefits. More research is necessary to understand the therapeutic potential of magnesium oil spray.

Magnesium oil spray is a topical remedy, meaning people spray it onto the skin or affected area.

Transdermal products like this bypass the gastrointestinal tract. Instead, the body absorbs them through the skin directly into the bloodstream. Transdermal substances can come in various forms, including patches, creams, or gels.

It is a good idea to speak with a healthcare professional before using natural remedies for health conditions. In some cases, alternative treatment with more scientific support may be available.

Additionally, people should patch test any new product on their skin to reduce the risk of a severe allergic reaction. People with skin conditions or sensitivities can speak with a healthcare professional before trying magnesium oil spray to ensure it is safe.

Magnesium oil spray has limited support in scientific research, which means researchers may not know the extent of the risks it could pose.

More research is necessary to understand the potential risks of transdermal magnesium as well as its benefits, including whether it shares the same potential risks as magnesium in other forms.

Magnesium oil sprays tend to consist of magnesium chloride flakes and water.

The recommended daily intake of magnesium for adults ranges from 310 milligrams (mg) to 420 mg. Getting more than this amount may lead to side effects, including gastrointestinal upset. Too much magnesium is called hypermagnesemia.

It can be challenging for someone to know how much magnesium is in their body when using transdermal products.

Magnesium can also interact with certain medications. Ultimately, it is a good idea to speak with a healthcare professional if someone wants to try using magnesium oil spray as a remedy. Their doctor may be able to recommend a safer form of this remedy.

Magnesium oil spray combines magnesium chloride flakes and water. Anecdotal evidence claims it offers various benefits, but there is limited scientific research to support this.

Most research on transdermal magnesium consists of small studies or older research. More research is necessary to understand if magnesium oil spray offers the same benefits as other transdermal magnesium products or supplements.

People can speak with a healthcare professional if they want to try magnesium oil spray. Their doctor can ensure they stay safe and use suitable products for their individual situation.
