Premium Bioactive Ingredients

  • High Magnesium citrate quality: ultra pure trimagnesium dicitrate (98%) with 14.5% elemental magnesium. Mg citrate contains in opposite only approx. 7% magnesium
  • Organic Magnesium citrate: a form of magnesium that is easily absorbed by the body
  • A fruit acid chelate of magnesium and citric acid with a distinctive set of effects and properties
  • pH-Value: approximately 7-8, neutral to slightly alkaline (magnesium hydrogen citrate has an acid value of 3.5-4.5)
  • Compared to other forms of magnesium:
    Magnesium content: ++ second highest
    Quick absorption: +++ very high
    Energy metabolism: +++ very high

How are we different?

The fruit acid chelate magnesium citrate is magnesium bound to citric acid. There are two types of magnesium citrate, which contain either approximately 7% or 15% elemental magnesium. The trimagnesium dicitrate we use has a high active ingredient content (15%), and is characterised by high bioavailability and absorption rates. It has an active ingredient purity of 98%+.

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 then package this product in environmentally friendly amber glass.

Tri-Magnesium Dicitrate

Magnesium citrate is base-forming, contributes to normal energy metabolism, normal muscle function, balance of electrolytes and normal protein synthesis. Tri-magnesium dicitrate is the magnesium compound with the second highest content of pure (elemental) magnesium.

Magnesium citrate is a highly bioavailable magnesium compound and has very good price/performance ratio. It is normally very well tolerated and quickly absorbed by the body, unlike, for example, magnesium carbonates, which are continuously absorbed over a longer period of time.

Magnesium for Muscles

Magnesium citrate is of particular importance to athletes, as it contributes, among other things, to normal energy metabolism, normal muscle function, electrolyte balance and normal protein synthesis.

Health Benefits of Magnesium According to the European Food Safety Authority (EFSA)

Magnesium contributes to:

  • The reduction of tiredness and fatigue
  • Electrolyte balance
  • Normal energy-yielding metabolism
  • Normal functioning of the nervous system
  • Normal muscle function
  • Normal protein synthesis
  • Normal psychological function
  • The maintenance of normal bones
  • The maintenance of normal teeth

and magnesium has a role in the process of cell division.


Recommended Dosage

Take 3 capsules (100mg pure magnesium per capsule) daily with 200ml water, ideally spread throughout the day.

Note: Spreading the dosage out across the day can improve absorption, since only a limited amount of magnesium can be absorbed at a time. Ideal intake times for magnesium include the morning just after waking, before lunch or after sports, and in the evening before bed. Taking magnesium on an empty stomach or 30 minutes before a meal can improve absorption.

Daily Requirements

The German Nutrition Society recommends a daily intake of between 300 and 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 250 mg 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 four 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 portions per day.

Food Supplement

Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Keep out of reach of children.


Store in a cool, dry place away from direct sunlight and heat.
