Can Magnesium help with fertility?

Magnesium is involved in many physiological processes relevant to fertility, including hormone regulation, oxidative stress reduction, and HPA axis function. Some small studies suggest low magnesium levels may be associated with both female and male subfertility. However, the overall evidence is weak: no large randomized controlled trials demonstrate that magnesium supplementation alone improves fertility outcomes. If a deficiency is confirmed (e.g., via blood test), supplementation (200–400 mg/day) may be reasonable, but it does not replace medical evaluation for underlying causes such as hormonal imbalances, endometriosis, or sperm quality issues. MyBody-X tests can identify nutrient gaps, but interpretation is individual. Caution: excessive doses can cause side effects like diarrhea or drug interactions. Consult a physician before supplementing, especially when trying to conceive.
