Did you know that an adult’s body contains approximately 1 kilogram of calcium, most of which is stored in the bones? This is no accident, as calcium salts are essential for many vital bodily functions. Calcium helps to:
- Strengthen bones and teeth
- Transmit nerve impulses, ensuring proper heart and muscle function
- Support blood clotting and wound healing
- Maintain the acid-base balance in blood, critical for protein function, as proteins can deteriorate in excessively acidic or alkaline conditions.
The daily calcium requirement for a healthy adult is 800 mg, though needs increase for women during their menstrual cycle, pregnancy, and for adolescents, especially after blood loss, prolonged inactivity, or fractures. Calcium deficiencies can lead to muscle cramps, nerve irritability, joint pain, and weakened bones.
Magnesium, on the other hand, acts as a catalyst in many energy-producing chemical reactions. The body contains around 20 grams of magnesium, primarily stored in the bones. Whole grains and leafy vegetables are excellent sources of magnesium. In cases of deficiency, magnesium supplements, such as tablets or magnesium-rich mineral water, can help restore levels. Magnesium deficiency can cause neurological issues, fatigue, muscle cramps, headaches, constipation, and stomach pain.
The recommended daily magnesium intake is 300 mg for women and 350 mg for men. This is particularly important for people consuming food from nutrient-depleted soil, pregnant and breastfeeding women, or patients with digestive issues that impact nutrient absorption.
