Vitamin C Zinc Ascorbate

Vitamin C Zinc Ascorbate (CAS 331242-75-2) is the zinc salt of L-ascorbic acid, delivering both vitamin C and zinc activity within a single compound. This dual-nutrient character makes it a technically efficient choice for formulators seeking to consolidate active ingredient loads in supplement matrices, while maintaining the well-documented functional profile associated with ascorbate chemistry. In the food supplement sector, Zinc Ascorbate is listed under Annex II of Directive 2002/46/EC as a permitted source of zinc (identified as zinc L-ascorbate), providing a clear regulatory pathway for manufacturers developing products for the EU market. Formulators should note that it does not appear in Annex II of Regulation 1925/2006 and should therefore not be positioned for general food fortification purposes under that framework.

Vitamin C carries a well-established set of authorised EU health claims under Regulation (EC) No 432/2012. These include contributions to normal collagen formation for the function of blood vessels, bones, cartilage, gums, skin and teeth; normal energy-yielding metabolism; normal functioning of the nervous and immune systems; protection of cells from oxidative stress; increase of iron absorption; and regeneration of the reduced form of vitamin E. These authorised claims represent a substantiated communication framework for finished product labelling and marketing materials. Within nutraceutical and supplement manufacturing, Zinc Ascorbate is primarily used in tablet, capsule, and sachet applications where a non-acidic or mildly buffered vitamin C source is preferred over straight ascorbic acid. Its comparatively gentle gastric profile is relevant for product positioning in sensitive-stomach formulations, and its zinc co-delivery simplifies bill-of-materials management for immune-support and antioxidant product ranges.

Pharmaceutical and healthcare applications may require material produced and tested in accordance with recognised pharmacopoeial standards. Buyers should request documentation confirming compliance with applicable quality frameworks, including Ph. Eur. or USP monograph alignment where relevant to their product registration or quality system requirements. Certificates of Analysis, full traceability documentation, and specification sheets are available on request. SoleChem supplies Zinc Ascorbate as a fine crystalline or powder-form material suited to direct blending and encapsulation processes. Packaging is offered in 25 kg fibre drums or cartons for standard bulk orders, with smaller 1–5 kg pack sizes available for development batches or lower-volume production runs. All consignments are supported by full batch documentation in line with EU distributor obligations under GMP-adjacent supply chain expectations.

As a European chemical distributor, SoleChem sources Zinc Ascorbate from audited manufacturing partners and maintains stock to support consistent supply continuity. Technical queries, sample requests, and documentation packages can be directed to the SoleChem commercial team.
