Benefits of Magnesium
Magnesium contributes to a wide range of bodily functions, including:
1. Muscle & Nerve Function
Magnesium regulates muscle contractions and nerve signals. It can help reduce cramps, spasms, and even migraines.
2. Bone Health
Around 60% of the body’s magnesium is stored in the bones. It works in tandem with calcium and vitamin D to maintain strong bones and prevent osteoporosis.
3. Heart Health
Magnesium helps maintain a steady heartbeat and may reduce the risk of high blood pressure, stroke, and heart disease.
4. Improved Sleep
Magnesium supports melatonin production and calms the nervous system, aiding deeper and more restful sleep.
5. Mental Health
Low magnesium levels are linked to increased anxiety, depression, and irritability. Supplementation may ease symptoms.
6. Blood Sugar Regulation
Magnesium plays a role in insulin metabolism and may improve blood sugar control, particularly in people with type 2 diabetes.
Magnesium Supplements
For those not meeting magnesium needs through diet alone, supplements are an option. Different forms have different uses and absorption rates:
Common Types of Magnesium Supplements:
| Type | Best For | Notes |
|---|---|---|
| Magnesium Citrate | Constipation, general use | High absorption, gentle laxative effect |
| Magnesium Glycinate | Anxiety, sleep, muscle cramps | Calming, good for long-term use |
| Magnesium Oxide | Indigestion, constipation | Less bioavailable, may cause loose stools |
| Magnesium Threonate | Cognitive health | Crosses blood-brain barrier |
| Magnesium Malate | Fatigue, fibromyalgia | Energy production, well absorbed |
Recommended Daily Dosage
The Recommended Dietary Allowance (RDA) for magnesium varies by age, gender, and life stage:
| Group | RDA |

| Adult women (19-30) | 310 mg/day |
