Functional classification of food additives: Food nutrition fortifier magnesium as a source of nutrients for food nutrition fortifiers has been listed in the "National Food Safety Standards for the Use of Food Nutrition Fortifiers" (GB14880), allowing it to be used in the preparation of milk powder and beverages and other foods Category, the magnesium L-threonate in this application is a source of magnesium compounds, used to formulate milk powder (except milk powder for children and milk powder for pregnant women) (food category 01.03.02) and beverages (14.01) And 14.06 (except for the related varieties) (food category 14.0). The US Food and Drug Administration approved it as one of the sources of magnesium compounds for use in food. Process necessity: Magnesium L-threonate is a food nutrient fortifier made by synthetic reaction of vitamin C, calcium carbonate, magnesium carbonate, etc. There are also many types of magnesium supplements for you to choose from, but—the one that can cross the blood-brain barrier and directly nourish the brain—is only magnesium L-threonate. Magnesium L-threonate is a mineral that benefits the brain. Magnesium L-threonate can penetrate the cell membrane of brain cells and increase the concentration of magnesium in the brain.
