About Magnesium

Micronutrient

Magnesium is a cofactor in over 300 enzymatic reactions, including ATP production, protein synthesis, DNA repair, and glucose metabolism. It regulates nerve and muscle function, blood pressure, and is required for the activation of vitamin D. Seeds (pumpkin, hemp, sunflower), dark chocolate, leafy greens, legumes, wholegrains, and nuts are excellent plant sources.

⚠️ Too little

Subclinical deficiency is common — symptoms include muscle cramps and twitches, poor sleep, anxiety, fatigue, headaches, and palpitations. Chronic low intake is associated with hypertension, type 2 diabetes, and osteoporosis. Excessive alcohol, stress, and diuretics all deplete magnesium.

🚫 Too much

From food, toxicity is not known. High-dose supplement use can cause diarrhoea and GI cramping — magnesium is used therapeutically as a laxative. Very high doses from supplements can cause low blood pressure and, rarely, cardiac toxicity. The upper limit for supplemental magnesium is 250 mg/day in the EU.
