Magnesium L-threonate capsules and tablets supplying 144 mg elemental magnesium per serving, for importers, distributors and pharmacy chains sourcing a specialty magnesium salt as a food supplement.

Product Description:

Magnesium L-threonate is the magnesium salt of L-threonic acid, a sugar acid formed when vitamin C breaks down. It is sold as a food supplement ingredient in capsules and tablets. The 144 mg on this page is elemental magnesium per daily serving, which is how labels usually express it. Magnesium makes up only about 7 percent of the salt by weight, so that serving needs roughly 2 g of the compound, split across several capsules or tablets a day.

Labels list both the weight of magnesium L-threonate and the elemental magnesium it supplies, with a serving often taken in divided doses. Capsule shells may be gelatine or plant-based HPMC, which matters for vegetarian, halal or kosher listings. Pharmacists will check the serving against national upper limits for supplemental magnesium and any warning statements a market requires. Product copy should carry only claims the target market has authorised, if any.

Sourcing notes. The regulatory category differs by market. Most class it as a food supplement, but the ingredient may need novel-food or new-ingredient status checked before launch. Key specifications are identity of the threonate salt, since other magnesium salts can be substituted, elemental magnesium assay against label claim, heavy metals such as lead, cadmium, arsenic and mercury, and microbial limits. Ask for a CoA per batch, a GMP or food-safety certificate, and allergen and GMO statements. Bottles with desiccant suit room-temperature storage. Give serving size, form, shell type, count per bottle, label language and shelf life on arrival.
