From the Research
Magnesium oil can be applied topically to the skin, but its effectiveness for various health benefits is not consistently supported by high-quality evidence, and its use should be approached with caution, particularly in patients with certain medical conditions or taking specific medications. When considering the use of magnesium oil, it's essential to focus on the most recent and highest quality studies. A study from 2020 1 found that oral magnesium supplementation had minimal effects on skeletal muscle cramps, which may imply that transdermal application could have similar limitations. However, another study from 2020 2 suggested that magnesium oil could improve arthritic joint mobility and reduce inflammation when used in conjunction with other treatments. For patients with fibromyalgia, a feasibility study from 2015 3 indicated potential benefits of transdermal magnesium chloride on quality of life, but this was a small pilot study and more research is needed to confirm these findings. Given the mixed evidence, the decision to use magnesium oil should be made on a case-by-case basis, considering the individual's specific health conditions and under the guidance of a healthcare provider. Some general guidelines for application include:
- Applying 5-20 sprays to the skin 1-3 times daily
- Focusing on areas with large muscle groups or muscle tension
- Massaging the oil into the skin until absorbed
- Starting with a small amount to test skin sensitivity and diluting with water if irritation occurs
- Avoiding application to broken skin, wounds, or sensitive areas
- Consulting a healthcare provider before use, especially for those with kidney disease or on certain medications.
