1. Muscle cramps
Magnesium is essential for muscle relaxation following contraction. When magnesium levels drop, muscles may remain contracted longer, leading to cramps, spasms, or persistent tension. These cramps commonly occur in the calves at night, after physical activity, or during periods of intense fatigue.
Although muscle cramps have multiple causes, magnesium deficiency is a key factor to consider, especially if cramps are frequent or severe. Increasing magnesium intake through diet or supplements may help alleviate these symptoms.
2. Persistent fatigue
Magnesium plays a central role in cellular energy production. It helps convert nutrients into adenosine triphosphate (ATP), the molecule that powers cellular functions. When magnesium is insufficient, the body’s ability to generate energy decreases, which can cause persistent feelings of fatigue and weakness even after adequate rest.
People with low magnesium levels often report improved vitality when they adjust their diet to include magnesium-rich foods such as leafy greens, nuts, and whole grains.
3. Heart palpitations
Magnesium regulates heart muscle contractions and maintains electrolyte balance critical for normal cardiac rhythm. Deficiency can cause symptoms like palpitations, irregular heartbeats, or a sensation of a racing heart.
Because heart palpitations may signal various cardiac conditions, it is important to rule out other causes. If you experience frequent or persistent palpitations, consult a healthcare professional for appropriate evaluation and testing, which may include an electrocardiogram (ECG) or serum magnesium measurement.
