What is Magnesium L Threonate:
Magnesium L Threonate powder is a binary compound of L-Threonic Acid and magnesium ion. Magnesium L Threonate is a degradation product of vitamin C. The simple edible salts of Magnesium L Threonate can promote the absorption and utilization of vitamin C in human body. In 2016, the National Health and Family Planning Commission issued Announcement No.8, which listed Magnesium L Threonate as a new variety of food nutrition fortifier to strengthen magnesium in food. The US Food and Drug Administration approved it as one of the sources of magnesium compounds for food use. Magnesium is an important nutritional factor of human body, which participates in many physiological activities of human body and has a special role in maintaining the functions of myocardium, nerves and muscles. In addition, it can also treat a variety of nervous system diseases, improve the refractory symptoms of schizophrenia, enhance memory ability, improve memory defects and so on.
Magnesium L Threonate powder is the enantiomer of threonine and the metabolite of vitamin C. L- ascorbic acid is an electron donor and an endogenous antioxidant.

The wide application of Magnesium L Threonate
Magnesium L Threonate powder is the basic unit of protein, which is widely used in food, medicine, additives and cosmetics industries.

Pharmaceutical industry
Magnesium L Threonate is the raw material for synthesizing human proteins, hormones, enzymes and antibodies. It participates in normal metabolism and physiological activities in the human body. Magnesium L Threonate and its derivatives can be used as nutritional enhancers, metabolic improvers and nutritional supplements.
feed additive
As a degradation product of vitamin C, Magnesium L Threonate can promote the absorption and utilization of vitamin C, thus improving its activity, and has a synergistic effect with insulin, so it can be widely used in the animal field.


Cosmetic industry
Magnesium L Threonate can form new brain cells and synapses-taking enough magnesium can help the brain maintain and form healthy brain cells and synapses. This will keep your brain alive. Thereby delaying skin aging.
Agricultural application
With the in-depth study of the physiological function of Magnesium L Threonate, its application in agriculture has gradually increased. First of all, magnesium ions can supplement the magnesium element missing in the soil and make the soil fertile.


biological engineering
Magnesium L Threonate is an organic magnesium salt. It is usually synthesized by threonic acid and magnesium ion through chemical reaction, and has good water solubility and bioavailability. Magnesium threonate does not exist directly in nature, but it can be obtained by artificial synthesis.
food additives
Magnesium, as a nutrient source of food nutritional fortifier, has been listed in the National Standard for Food Safety, Standard for the Use of Food Nutritional Fortifier (GB14880), and it is allowed to be used to prepare food categories such as milk powder and beverages. Magnesium L Threonate in this application is a compound source of magnesium, which is used to prepare milk powder (except milk powder for children and milk powder for pregnant women). The US Food and Drug Administration has approved it as one of the compound sources of magnesium to be used in food.

How does Magnesium L Threonate improve anxiety?
Higher stress level may lead to magnesium deficiency by increasing magnesium loss with urine.
In addition, magnesium deficiency can also increase stress response.
In animals, magnesium deficiency will increase the mortality caused by stress, and effectively correcting magnesium deficiency can improve the ability of nervous system to resist stress.
In other words, stress will lead to magnesium deficiency, which in turn will lead to stress.
Animals receiving low magnesium diet showed more anxiety-related behaviors, which may be due to the high excitability of the brain and the increase of cortisol production.
Importantly, two studies have proved that supplementing Magnesium L Threonate to animals can relieve anxiety.
Therefore, Magnesium L Threonate may play a central role in relieving anxiety. In short, anxiety can lead to magnesium deficiency, and vice versa. Considering that most people in the United States fail to get enough magnesium through diet, it may play an important role in relieving anxiety by supplementing Magnesium L Threonate powder.
Safety information of Magnesium L Threonate
Magnesium L Threonate powder is a low toxic compound and has no obvious acute toxic effect on human body. However, appropriate protective measures should still be taken during operation, such as wearing protective glasses and gloves to avoid inhalation and contact with skin. Observe the relevant safety operation procedures and store them in a dry and well-ventilated place, away from fire sources and combustible materials. Correct laboratory operation methods should be followed when using and handling magnesium L- threonate.
