Magnesium oil can be rubbed onto the skin or sprayed when placed in a spray bottle. It may offer anti-inflammatory and antioxidant benefits, but scientific evidence supporting the effectiveness of topical magnesium remains limited.

This oil is created by mixing magnesium chloride flakes with water. The resulting solution has an oily texture, though it isn’t a true oil.

Magnesium is a vital nutrient that contributes to several body functions, including:

• Regulating nerve and muscle function
• Managing blood sugar and blood pressure levels
• Maintaining protein, bone, and DNA health

When applied topically, magnesium oil may help raise the body’s magnesium levels through a process known as transdermal absorption. However, while oral magnesium supplements are backed by substantial research, evidence supporting topical use is much more limited.

Preliminary studies show some promise, but more research is necessary to confirm any health benefits of using magnesium oil on the skin.

A Note on Supplements

The Food and Drug Administration (FDA) does not regulate supplements for quality, purity, or dosage. As a result, many supplements on the market haven't been fully tested for safety. If you're considering magnesium oil or any supplement, it's best to speak with a healthcare professional. They can help determine if it's right for you and suggest appropriate alternatives or dosage guidance.

When purchasing, choose products with third-party certification (like NSF International or USP) to ensure you're getting a reliable formula.

Benefits and Uses

Magnesium deficiency has been associated with several chronic conditions, including:

• Diabetes
• Hypertension
• Heart disease
• Stroke
• Osteoporosis
• Migraine headaches

While most studies have focused on dietary and oral magnesium supplements, a few recent trials suggest topical magnesium might also provide benefits.

Neuropathy and Chronic Kidney Disease (CKD)

A 2023 study involving 26 participants with CKD explored magnesium oil's effect on peripheral neuropathy. Each participant sprayed a magnesium chloride solution on their skin once daily for 12 weeks. While their body’s magnesium levels didn’t change significantly, many reported decreased neuropathic pain and symptom frequency.

Fibromyalgia

In 2015, researchers found that applying magnesium chloride to the arms and legs of fibromyalgia patients helped reduce pain. Participants used four sprays per limb, twice daily, for one month.

Wound Healing

Animal studies in 2023 also indicate that magnesium-based creams may promote faster wound healing, though human trials are needed.

Forms of Magnesium

Magnesium supplements are most often taken orally in capsule or pill form. But you can also find magnesium as:

• Oil
• Cream
• Spray
• Bath salts (like Epsom salt)

A 2017 review of several studies found little benefit to magnesium sulfate baths, despite their popularity. However, DIY magnesium oil can be made at home by combining magnesium chloride flakes with boiled, distilled water.

Can You Put Magnesium Oil on Your Skin?

Yes, but do a patch test first to avoid irritation. Here’s how:

1. Wash and dry a small area on your forearm or thigh.
2. Apply a small amount of magnesium oil.
3. Cover it with a bandage for 24 hours.
4. If irritation, rash, or discomfort occurs, rinse with gentle soap and water.
5. If no reaction occurs, it’s likely safe to use on a wider area.

Side Effects and Risks

Topical magnesium may not have the same effect as oral supplements. Dosage can also be difficult to measure when applied to the skin.

According to the National Institutes of Health (NIH), the upper limit for daily magnesium intake from supplements is 350 mg for individuals aged 9 years and older. Overconsumption may lead to symptoms such as:

• Diarrhea
• Muscle cramps
• Nausea
• In extreme cases: irregular heartbeat or cardiac arrest

The Bottom Line

Magnesium oil is gaining popularity as a potential remedy for conditions like muscle pain, migraines, and sleep problems. While early research is promising, there's not yet enough evidence to support its widespread medical use.

If you're considering magnesium oil for supplementation or symptom relief, consult a healthcare professional to find out what’s right for your body and needs.
