Is Magnesium useful for fertility?

Magnesium is an essential mineral involved in over 300 enzymatic reactions, including those relevant to fertility. Human studies suggest that adequate magnesium status may support fertility by reducing oxidative stress, improving hormone regulation, and positively influencing egg and sperm quality. Deficiency has been linked to menstrual irregularities, insulin resistance, and reduced sperm motility. However, the evidence is not conclusive: randomized controlled trials specifically examining magnesium supplementation for fertility are limited. Most data come from observational studies or indirect associations. A balanced diet rich in magnesium (nuts, seeds, whole grains, leafy greens) is generally recommended. MyBody-X tests do not measure magnesium levels or provide direct supplementation advice. For fertility concerns, a doctor should assess individual nutrient status. Evidence: human-moderate.
