Vitamin C Magnesium L-Ascorbate

Vitamin C Magnesium L-Ascorbate (CAS 15431-40-0) is the magnesium salt of L-ascorbic acid, offering a buffered, non-acidic source of Vitamin C combined with a bioavailable form of magnesium. Its near-neutral pH profile makes it a technically practical alternative to ascorbic acid in formulations where acidity is a processing or tolerance concern. In the food supplement sector, Vitamin C Magnesium L-Ascorbate is listed under Annex II of Directive 2002/46/EC as a permitted source of both Vitamin C and magnesium, supporting its use across EU-marketed dietary supplements. Formulators can leverage the authorised EU health claims associated with Vitamin C under Regulation (EC) 432/2012, which recognise its contribution to normal collagen formation, energy-yielding metabolism, immune system function, protection of cells from oxidative stress, iron absorption, nervous system function, and the regeneration of Vitamin E. These claims apply subject to the conditions of use specified in the Regulation.

For nutraceutical and supplement manufacturers, the ingredient is well-suited to capsule, tablet, and powder blend applications. Its buffered character is particularly relevant where gastric sensitivity is a formulation consideration. The dual mineral-vitamin profile also appeals to combination supplement formats targeting general wellness or sports nutrition positioning. In food and nutrition applications, the compound functions as an antioxidant and stabiliser, helping to protect formulations from oxidative degradation. It is typically supplied as an off-white to pale yellowish free-flowing powder, with standard quality benchmarks including loss on drying not more than 10.0%, pH in the range of 6.0–8.5, and sulfate levels within accepted limits consistent with food-grade specifications.

Personal care and cosmetic formulators use Vitamin C Magnesium L-Ascorbate for its antioxidant and humectant properties in skin-facing applications. Its improved stability relative to free ascorbic acid and its compatibility with aqueous systems make it a practical active ingredient in serums, creams, and treatment formulations where oxidative stress protection and moisture retention are formulation objectives. SoleChem supplies Vitamin C Magnesium L-Ascorbate to food-grade and cosmetic-grade quality standards. Bulk material is available in 25 kg fibre drums or cartons as standard commercial packaging, with smaller lot sizes of 1–5 kg available to support R&D, scale-up, or low-volume production requirements.

As a European distributor with established supply chain relationships, SoleChem can provide consistent batch quality, documentation support including certificates of analysis and safety data sheets, and technical assistance for specification alignment across supplement, food, and cosmetic applications.
