Can Low Magnesium Cause Anxiety?

Yes, low magnesium levels can contribute to anxiety symptoms. Magnesium deficiency affects over 50% of adults and can disrupt neurotransmitter function, particularly GABA, which helps regulate mood and stress responses. Studies show that magnesium supplementation can reduce anxiety scores by up to 25% in deficient individuals. Common signs of magnesium deficiency include muscle cramps, fatigue, irritability, and heightened stress sensitivity. The recommended daily intake is 400-420mg for men and 310-320mg for women. Blood tests can accurately measure magnesium levels, though normal serum levels don't always reflect tissue stores.
