Magnesium protects us against many modern ills

Sulphur, calcium and magnesium are called “secondary macronutrients” for crops because plants require relatively large amounts of them. All three are also needed by humans. The role of calcium in bone development is well known, and sulphur is needed for healthy cartilage, hair and skin.

Although magnesium is abundant in the universe, human deficiencies are frequent, including in developing countries, and its role in health is probably underestimated by most people.

Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve functions, keeps the heart rhythm steady, supports the immune system and contributes to strong bones. Magnesium also helps regulate blood sugar levels, promotes normal blood pressure and is known to be involved in both energy metabolism and protein synthesis. Magnesium is therefore vital to help prevent and manage disorders such as hypertension, cardiovascular disease and diabetes.

Symptoms of magnesium deficiency include tiredness, weakness, loss of appetite, cardiac arrhythmia, anemia, cramps, mood swings, irritability, lethargy and depression. Too little magnesium has also been linked to asthma, osteoporosis and attention disorders.
