Magnesium Oxide
400mg Capsules
Extended Release
Magnesium as magnesium oxide, providing 700mg per capsule sourced from the Dead Sea. This form of magnesium has a 57% magnesium content, which corresponds to 400mg pure magnesium per capsule. A premium quality ingredient with exceptional purity (over 99.98%). No unnecessary additives, non-GMO, vegan. Year's supply: 365 capsules
- Magnesium oxide from the Dead Sea contains the highest magnesium content of all forms of magnesium (57%), ideal for high-dose servings
- Magnesium contributes to a reduction of tiredness and fatigue, electrolyte balance, normal energy-yielding metabolism, the nervous system, muscle function, psychological function, protein synthesis, maintenance of normal bones and teeth, and has a role in the process of cell division
- Slower and more continuous bioavailability compared to other forms
- Directions: Take 1 capsule daily with 200ml of water
How are we different?
We use a magnesium oxide of the highest quality and exceptional purity, naturally sourced from the Dead Sea. This natural magnesium oxide possesses the highest magnesium content of all forms of magnesium, at 57%. Our magnesium oxide is entirely free from any unnecessary additives.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG.We use environmentally friendly amber glass jars for the packaging of this product.

Effects
Effects
Magnesium Oxide
Magnesium oxide stands out with an impressive 57% magnesium content, far surpassing the typical 5–10% found in other magnesium compounds due to the single oxide atom bond. This allows a high dose to be taken with just one capsule.
The chemical reaction between magnesium oxide and the hydrochloric acid present in the stomach produces magnesium chloride and water, thereby neutralising stomach acidity at high doses. This characteristic makes it less advisable for individuals with low stomach acid levels.
According to the European Food Safety Authority (EFSA):
Magnesium contributes to:
- the reduction of tiredness and fatigue
- electrolyte balance
- normal energy metabolism
- normal functioning of the nervous system
- normal muscle function
- normal protein synthesis
- normal mental function
- the maintenance of normal bones & teeth
- cell division
Dosage
Dosage
Directions
Take 1 capsule (400mg magnesium) daily with 200ml water.
Daily Requirements
The German Nutrition Society recommends a daily intake of between 300–400mg of magnesium (NRV: 375mg). However, individual magnesium needs may vary according to biochemical factors, and can be significantly increased during stressful periods.
Note: According to the German Federal Institute for Risk Assessment (BfR), magnesium intake through supplements should not exceed a maximum daily amount of 250mg of magnesium in food supplements in order to avoid a laxative effect (mild diarrhoea). The maximum amount applies to persons aged four years and older. For infants under 4 years of age, there is no such guidance relating to a daily maximum due to lack of data.
The BfR recommends that the daily dose be divided into at least two separate doses per day. This is because scientific data shows that magnesium tolerability is increased when intake is spread between two or more doses per day.
Food Supplement
Do not exceed the recommended daily intake. Food supplements are not a substitute for a balanced, varied diet and healthy lifestyle. Keep out of reach of young children.
Storage
Store in a cool, dry place away from direct sunlight and heat.
