What should I know about magnesium fur nerven?

Magnesium is an essential mineral involved in over 300 enzymatic reactions, including nerve transmission and muscle relaxation. While mechanistic evidence supports its role in nerve function, clinical evidence for magnesium supplements specifically for 'nerves' (e.g., stress, sleep, cramps) is mixed and often limited to small studies. Deficiency can cause symptoms like muscle twitching, irritability, and fatigue. However, for most people with a balanced diet, supplementation is unnecessary. MyBody-X does not directly test magnesium levels in its current offerings. If you suspect a deficiency, a blood test (serum magnesium) is recommended, but note that serum levels may not reflect total body stores. Always consult a healthcare professional before starting supplements. Evidence: mechanistic.
