How are we different?

Our premium Magnesium Complex Ultra capsules contain seven selected forms of magnesium: Magnesium citrate, -malate, -gluconate, -ascorbate, -taurate, -glycinate and -carbonate (from Sango coral). The magnesium compounds magnesium citrate, -malate, -gluconate, -ascorbate, -taurate and -glycinate are derived from fruit-based acids as well as amino acid chelates. The individual magnesium compounds are of the highest quality and purity. Our Sango coral is sourced from sustainable mining in water at depths of over 50m around the island of Okinawa. We never source coral from land mining on the island itself. The sediment found on the island has been washed out by acid rain and, as a result, contains barely any marine trace elements.

Our Magnesium Complex Ultra combines the different nutrients and reabsorption rates of the various magnesium compounds into a product of exceptionally high tolerability and bioavailability for dietary supplementation in cases of increased magnesium requirements. The valuable magnesium compounds of various fruit and amino acids as well as Sango coral are therefore combined in an optimised ratio. Each form of magnesium in this complex has a different effect and can be absorbed by different tissues (muscles, brain, organs). Taken together, these 7 types of magnesium provide complete coverage for the whole body. The high level of absorption results from the exclusive use of organic magnesium compounds.

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.

Magnesium Glycinate

Magnesium glycinate is bound to the amino acid glycine. Large amounts of glycine can be found in connective tissue and the brain. Magnesium glycinate is considered to be one of the most bioavailable magnesium compounds, and it positively contributes to normal protein synthesis, a healthy nervous system, and psychological functioning.

Magnesium Taurate

Magnesium taurate is bound to the amino acid taurine. Large amounts of taurine can be found in muscle and eye tissues, as well as the brain. Magnesium taurate contributes to the reduction of tiredness and fatigue, normal protein synthesis, and normal muscle functioning.

Magnesium Citrate

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. Magnesium citrate is base-forming, contributes to energy metabolism, healthy muscles, electrolyte balance and protein synthesis.

Magnesium Malate

Magnesium malate is a salt of malic acid and contributes to normal energy metabolism, the reduction of tiredness and fatigue, and normal functioning of the nervous system.

Magnesium Gluconate

Magnesium gluconate is a salt of gluconic acid (fruit acid), which can be found in kombucha. Magnesium gluconate is highly bioavailable and contributes to normal energy production metabolism and normal nervous system function. It also plays a role in cell division.

Magnesium Ascorbate

Magnesium ascorbate, also known as buffered vitamin C, is a salt of ascorbic acid (vitamin C). It is very well tolerated and has a high bioavailability.

Magnesium Carbonate from Sango Coral

Sango corals form calcium and magnesium carbonate structures in an optimal ratio of approximately 2:1, as can be similarly found in the human body (in teeth and bones). For this reason, Sango coral is also suitable for the production of dental implants which, instead of being rejected by the body, can grow together with the jaw and enrich its bone substance. Thanks to its highly porous structure, Sango coral is comparatively quickly absorbed for a carbonate, and in addition to calcium, it supplies more than 70 other trace elements.

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.
