What is the purpose of this trial?

This trial explores whether magnesium intake can alter body composition, such as muscle and fat levels, in physically active individuals. Participants will take a magnesium capsule daily for eight weeks and record their diet and exercise habits. The study seeks individuals who have been physically active for at least a year and have a BMI between 19 and 30. Smokers or those with certain health conditions may not qualify for this trial. As an unphased trial, it offers a unique opportunity to contribute to understanding magnesium's effects on active individuals.

Will I have to stop taking my current medications?

The trial requires that you do not take medications that can interfere with body composition. If your current medications fall into this category, you may need to stop taking them to participate.

Is there any evidence suggesting that magnesium supplementation is likely to be safe for humans?

Research has shown that magnesium is generally safe for use. The FDA has evaluated magnesium in dietary supplements and found it safe at normal supplement levels. Studies indicate that magnesium is usually well-tolerated, with only minor side effects, such as an upset stomach, in some cases.

Considering participation in a trial for magnesium supplements, it is reassuring that magnesium has been extensively studied and is widely used as a supplement. No major safety concerns have been reported for magnesium at the dose administered in this trial. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about magnesium supplementation for body composition changes because it offers a natural and straightforward approach compared to more invasive or pharmacological interventions. While typical treatments might include dietary adjustments or more complex supplements, magnesium is a simple mineral that plays a crucial role in muscle function and metabolism. This treatment is administered in an extended-release capsule, potentially offering more stable magnesium levels throughout the day, which could enhance its effectiveness and convenience for daily use.

What evidence suggests that magnesium supplementation might be an effective treatment for body composition changes?

Studies have shown that magnesium supplements can increase muscle size and strength, potentially improving body shape. They may also speed up recovery after exercise and reduce muscle soreness. Research suggests a link between higher magnesium intake and a lower risk of obesity, indicating potential benefits for weight management. Additionally, magnesium plays a crucial role in energy use, muscle movement, and protein building. Together, these factors suggest magnesium could positively affect body shape for active individuals. ^{6 7 8 9 10}

In a study of 61 healthy young women, magnesium oxide supplementation for 10 days significantly increased both ionized magnesium levels and total magnesium percentage, indicating its superior bioavailability compared to other forms.

Magnesium citrate led to an increase in the ionized fraction but a decrease in total magnesium concentration, while magnesium carbonate resulted in a decrease in ionized magnesium without affecting total magnesium levels, suggesting varying effects of different magnesium supplements.

Recent evidence from 10 studies, including 5 meta-analyses and 5 randomized controlled trials, suggests that magnesium (Mg) supplementation above the current tolerable upper intake level (UL) of 350 mg/d does not significantly increase the risk of diarrhea in adults.

The analysis indicates that higher doses of magnesium (up to 1200 mg/d) can be safely consumed without major gastrointestinal adverse events, supporting the idea that the UL for magnesium should be re-evaluated to potentially allow for greater supplementation and reduce undernutrition.
