Magnesium
Magnesium is an essential mineral involved in over 300 enzymatic reactions. It is critical for energy production, protein synthesis, and maintaining the structural integrity of bones and cell membranes.
Functions and Benefits
Recommended Dietary Allowance (RDA)
| Life Stage | Age Group | Men (mg/day) | Women (mg/day) |
|---|---|---|---|
| Infants | 0 – 12 months | 30 – 75 mg | 30 – 75 mg |
| Children | 1 – 13 years | 80 – 240 mg | 80 – 240 mg |
| Teens & Adults | 14 – 30 years | 400 – 410 mg | 310 – 360 mg |
| Elderly | 31+ years | 420 mg | 320 mg |
| Maternal | Pregnancy / Nursing | – | 310 – 400 mg |
*Note: Modern agricultural soil depletion makes obtaining sufficient Magnesium from food increasingly difficult.
Top Food Sources (mg)
Seeds & Nuts: Cashews (83mg), Almonds (77mg), Peanuts.
Grains: Oat Bran (96mg), Brown Rice (86mg), Whole Grains.
Produce: Frozen Spinach (78mg), Avocado (58mg), Banana.

Risks of Deficiency and Overdose
Causes muscle cramps, heart arrhythmias, fatigue, and headaches. Long-term lack is linked to hypertension and diabetes.
Excessive supplement intake often has a laxative effect (diarrhea). Extreme doses can lead to muscle weakness and kidney failure.
Disease Prevention
Metabolic Regulation: Magnesium supports healthy carbohydrate and fat metabolism, reducing the risk of metabolic disorders and Type 2 Diabetes.
Cardiovascular Health: By preventing arrhythmias and supporting vascular health, it acts as a primary defender against heart disease.
Conclusion: From DNA synthesis to heart rhythm, Magnesium is non-negotiable for health. Due to soil depletion, balanced supplementation alongside magnesium-rich green leafy vegetables is often recommended.
