What makes magnesium L-threonate special?

Magnesium L-threonate is a unique form of magnesium bound to L-threonic acid – a vitamin C breakdown product. This compound is known for its excellent absorption, enabling efficient magnesium uptake by the body. Developed in the USA under the name Magtein® by Threotech LLC.

How does magnesium support the body?

Magnesium contributes to normal nervous system and psychological function, promotes a normal energy-yielding metabolism and supports electrolyte balance. It also plays a role in cell division and helps reduce tiredness and fatigue. With 3 capsules per day, the body is provided with 144 mg of magnesium in a highly bioavailable form.

We offer a range of different magnesium salts. To understand the difference between them, we need to take a brief detour into chemistry. Elemental magnesium is always positively charged and must therefore find a negatively charged bonding partner in order to exist as a stable, balanced salt.

There are a wide variety of magnesium salts, but not all of them dissolve well in the body and are therefore able to release magnesium to our cells (bioavailability). We primarily offer highly bioavailable and organically bound forms of magnesium.

But why do we actually need magnesium in our bodies? We are all familiar with ‘calf cramps’ and know that magnesium can help with these. It can be said that magnesium acts on cramps in the body by promoting muscle relaxation, regulating calcium uptake into muscle cells and maintaining electrolyte balance. Furthermore, magnesium is involved in over 600 reactions in the body, making it a very important mineral for our bodies. In addition to the muscles, it also contributes to the maintenance of normal bones and teeth. It contributes to normal protein synthesis and plays a role in cell division.

We therefore need to provide our bodies with a form of magnesium that dissolves easily. Magnesium can, for example, be bound to citric acid (magnesium citrate) or taurine (magnesium taurate). When the magnesium salt dissolves in the body, we are not only supplied with magnesium but also with the corresponding binding partner. This leads to the following conclusions:

Magnesium citrate: magnesium + citric acid – highly soluble, may gently stimulate bowel function. Magnesium contributes to electrolyte balance and normal energy metabolism.
Magnesium malate: magnesium + malic acid – considered well tolerated, may gently stimulate bowel function. Magnesium also contributes to normal muscle function and to the reduction of tiredness and fatigue.
Magnesium ascorbate: magnesium + ascorbic acid (vitamin C) – focuses on vitamin C supply, highly soluble and gentle on the stomach.
Magtein® (magnesium L-threonate): Magnesium + L-threonic acid – special chemical structure, well tolerated, currently the subject of research in the field of cognitive function. Magnesium contributes to the normal functioning of the nervous system and to normal psychological function. Focus on the nervous system and as a supplement during periods of mental strain.
Magnesium (bis)glycinate: magnesium + the amino acid L-glycine – chelated form, very stable, very well tolerated. Magnesium also contributes to normal psychological function and to the normal functioning of the nervous system. Focus on the nervous system and psychological well-being; suitable for stress and inner restlessness; often preferred in the evening.
Magnesium taurate: magnesium + the amino acid taurine – stable chelate structure, well tolerated. Magnesium also contributes to normal muscle function. Focus on cardiac and vascular muscles.
Magnesium oxide – sourced from the Dead Sea with a particularly high content of elemental magnesium (60%).

We offer these forms of magnesium as individual supplements; in addition, we have the following combination products:

Magnesia 7+1 – our colourful blend of 7+1 magnesium salts (magnesium citrate, magnesium bisglycinate, magnesium malate, magnesium taurate, magnesium gluconate, magnesium lactate, magnesium phosphate, magnesium carbonate).
Calcium & Magnesium – calcium and magnesium contribute to normal muscle function and the maintenance of normal bones
Magnesium Malate & Glycinate – organic magnesium compounds with rapid absorption. Magnesium also contributes to normal muscle function, to the reduction of tiredness and fatigue, and to the normal functioning of the nervous system.

Summary: Magnesium must always find a binding partner and exist in the form of a salt. This binding partner, in turn, can offer benefits for the body or have effects on the target tissue. By carefully selecting the right magnesium salt, you can prioritise different areas of the body – for example, the muscles, heart, nerves, energy levels or cognitive function.

Which magnesium compound is best suited depends primarily on individual tolerability, the preferred time of intake, and the individual dietary situation.

For versatile magnesium supplementation

Those who want to combine different magnesium compounds can opt for a combination product. Magnesia 7+1 contains eight different magnesium salts, providing a broad-based magnesium supply.

Which form of magnesium is suitable for digestion?

Magnesium citrate and magnesium malate can mildly stimulate intestinal activity and soften the stool. They are therefore often preferred in cases of sluggish digestion.

Those who tend to have loose stools or diarrhea should initially use these forms with caution and can alternatively choose well-tolerated compounds such as magnesium bisglycinate or magnesium taurate.

Which form of magnesium is suitable at which time of day?

Magnesium citrate, magnesium malate, magnesium taurate, and magnesium L-threonate are often taken in the morning or during the day. Magnesium bisglycinate is often preferred in the evening due to its combination with the amino acid glycine.

Higher amounts of magnesium should ideally be divided into several smaller portions throughout the day. This can improve tolerability.

Organic magnesium compounds are generally highly soluble, are absorbed rapidly and are considered to be particularly well tolerated. They are particularly suitable for situations where there is an increased need for magnesium or where the digestive system is sensitive.
Inorganic magnesium compounds contain a high proportion of elemental magnesium and are released more slowly. They are particularly suitable for replenishing magnesium stores over the long term.

A combination of both forms may be beneficial in order to combine rapid availability with a sustained supply.

Magnesium L-threonate (Magtein®) is a specialised magnesium compound containing L-threonic acid, a breakdown product of vitamin C.
This form of magnesium is the subject of current research into the nervous system and cognitive functions, and is specifically used when the focus is on mental performance and concentration.

Depending on the compound, magnesium can have a laxative effect.
A common cause is that magnesium citrate draws water into the bowel, which can lead to diarrhoea.

Alternatives that are better tolerated:

Magnesium glycinate
Magnesium taurate
Magnesium threonate

These forms are particularly suitable for people with sensitive systems.
