Magnesium Oxide - MgO (240mg elemental magnesium x 60 Caps @ 1.2 cent per mg)

South Africa’s Most Cost-Effective Magnesium Supplement 

They will never tell you that  Magnesium Oxide (MgO) is the best-value magnesium supplement in South Africa. Each capsule delivers 240 mg of elemental magnesium—more than any other form, gram for gram, ensuring maximum absorption and benefits for your body. See below the amounts of elemental magnesium in other compounds like magnesium glycinate.

Why Magnesium Is Essential

Magnesium supports over 300 bodily functions, including muscle and nerve health, bone strength, and blood sugar regulation. Most South Africans are deficient, as modern diets and purified water lack the 600+ mg of elemental magnesium our ancestors absorbed daily from mineral-rich wells and fountains. The outdated RDA (300–420 mg) underestimates true needs due to low absorption and losses in stool and sweat. 

Key Benefits of Magnesium Oxide - MgO

• Muscles & Bones: Enhances muscle strength, endurance, and bone health; helps prevent osteoporosis and speeds fracture healing. 
• Brain & Mood: Improves sleep quality, focus, memory, and calmness while reducing anxiety and migraine frequency. 
• Stress & Immunity: Lowers cortisol (stress hormone), boosts GABA (calming hormone), and strengthens immune response. 
• Digestion: Neutralizes stomach acid to relieve heartburn and indigestion. 
• Bonus: Supports healthy sleep patterns and may alleviate PMS symptoms. 

Why Choose 240mg MgO? 

• Superior Absorption: Capsules (not tablets) dissolve rapidly in stomach acid, achieving 22.8% bioavailability—comparable to magnesium glycinate (23.5%). 
• Enhanced with D-Ribose: Boosts magnesium absorption for a noticeable energy lift within hours. 
• Safe & Gentle: Less likely to cause diarrhea compared to other magnesium forms. Excess is safely excreted, preventing overdose.
• Comparison: 
  • Magnesium Glycinate (500 mg): 70 mg elemental magnesium 
  • Magnesium L-Threonate (500 mg): 40 mg elemental magnesium 
  • Magnesium Citrate (500 mg): 55 mg elemental magnesium 
  • Magnesium Malate (500 mg): 60 mg elemental magnesium 
  • Magnesium Oxide (500 mg): 240 mg elemental magnesium 

Who Needs Magnesium Oxide?

Perfect for athletes, students, mothers, executives, and the elderly. Supports conditions like depression, insomnia, ADHD, and more. During pregnancy, MgO reduces stress and promotes a calmer baby, supporting brain and bone development.

How Much Magnesium Do You Need?

Take two capsules MgO daily (480 mg elemental magnesium) plus dietary sources (e.g., 105 mg from 50 g Nucleo) to reach the recommended 600+ mg of daily elemental magnesium. High-performance athletes may safely take up to five capsules daily.

For improved sleep take the 2 x MgO caps before bed. 

Why Avoid Calcium Supplements?

Unlike magnesium and vitamin D3, calcium supplements don’t improve bone density and may increase mortality risk above 300 mg daily. Focus on magnesium for optimal bone health.
