4. Magnesium Supplements
If you struggle to meet your magnesium needs through diet alone, you may consider taking a magnesium supplement. These supplements are available in various forms, including magnesium citrate, magnesium oxide, and magnesium glycinate.
It’s important to speak with your healthcare provider before starting any new supplement, as they can help determine the appropriate dosage and ensure it doesn’t interfere with any medications you may be taking.
5. Potential Side Effects of Excessive Magnesium Intake
While magnesium is generally safe when consumed in moderate amounts, excessive intake can lead to side effects. These may include diarrhea, nausea, stomach cramps, and in severe cases, irregular heartbeat or cardiac arrest.
It’s important to stick to the recommended daily intake and avoid excessive magnesium supplementation unless advised by a healthcare professional.
