These studies suggest that magnesium cream may improve magnesium levels in non-athletes and have a small effect on nocturnal leg cramps in pregnant women, but is not effective for leg cramps in the general population.

Side Effects of Magnesium Cream: A Comprehensive Review
Introduction to Magnesium Cream
Magnesium cream is a topical formulation designed to deliver magnesium transdermally, potentially improving magnesium levels in the body. This method is often considered as an alternative to oral magnesium supplements, which can sometimes cause gastrointestinal discomfort. However, the side effects of magnesium cream itself are not widely discussed. This article synthesizes findings from recent research to provide a clear understanding of the potential side effects associated with magnesium cream.
Gastrointestinal Side Effects
Comparison with Oral Magnesium
One of the primary advantages of magnesium cream over oral supplements is the potential reduction in gastrointestinal side effects. Oral magnesium is known to cause issues such as diarrhea and stomach cramps in some individuals. In contrast, transdermal application aims to bypass the digestive system, potentially minimizing these adverse effects.
Evidence from Studies
A systematic review of randomized controlled trials (RCTs) comparing magnesium therapy for nocturnal leg cramps (NLC) found that gastrointestinal side effects were slightly more common with oral magnesium therapy than with placebo. However, this review did not specifically address transdermal magnesium, indicating a gap in the literature regarding the side effects of magnesium cream.
Skin Irritation and Allergic Reactions
Potential for Skin Reactions
As with any topical product, there is a potential for skin irritation or allergic reactions when using magnesium cream. These reactions can include redness, itching, or a rash at the site of application. However, the pilot study on transdermal magnesium cream did not report any significant skin-related side effects among participants.
Need for Further Research
The absence of reported skin reactions in the pilot study suggests that magnesium cream may be well-tolerated by most users. Nonetheless, larger and more comprehensive studies are needed to confirm these findings and to identify any rare or long-term side effects.
Systemic Side Effects
Absorption and Systemic Impact
The pilot study on transdermal magnesium cream demonstrated that magnesium can be absorbed through the skin, leading to an increase in serum magnesium levels. However, the study did not report any systemic side effects directly attributable to the magnesium cream. This suggests that, at least in the short term, magnesium cream does not pose significant systemic risks.
Comparison with Placebo
In the same study, the placebo group did not show any significant changes in serum or urinary magnesium levels, nor did they report any adverse effects. This further supports the notion that magnesium cream is relatively safe for short-term use.
Conclusion
Current research indicates that magnesium cream is a promising alternative to oral magnesium supplements, particularly for individuals who experience gastrointestinal side effects from oral formulations. While the pilot study on transdermal magnesium cream did not report significant side effects, including skin irritation or systemic issues, further research is necessary to fully understand the long-term safety profile of this product. For now, magnesium cream appears to be a safe and effective option for increasing magnesium levels with minimal side effects.
