Everything You Wanted to Know About Magnesium

Magnesium is an essential mineral that supports over 300 processes in your body. It contributes to energy production, muscle function, stress management, heart health, and sleep quality.

Magnesium naturally occurs in green leafy vegetables, nuts, seeds, whole grains, avocados, bananas, and dark chocolate. Modern diets and depleted soil make it difficult to get enough magnesium from food alone.

Deficiency symptoms include muscle cramps, fatigue, stress, anxiety, headaches, restless legs, and sleep problems. Other signs are irritability, low energy, and difficulty concentrating. Consult a healthcare provider for testing. Possible tests include blood tests (serum magnesium), urine tests, and red blood cell (RBC) magnesium tests.

Most adults need 300–400 mg per day, depending on age, sex, and life stage. Stress, physical activity, or pregnancy can increase your need. Please check our OMgenie for personal advice.
