We are a company dedicated to the R&D and large-scale production of high-purity, gentle, and highly bioavailable Vitamin C derivatives. We offer pure Sodium Ascorbate powder-a buffered form of Vitamin C created by chelating L-ascorbic acid with sodium ions. With its neutral pH, this product completely resolves the common issue associated with traditional Vitamin C-namely, its "strong acidity causing stomach irritation"-while fully preserving its antioxidant activity.
The two most common challenges encountered when taking Vitamin C are either gastric intolerance due to acidity or inconsistent efficacy. Ordinary ascorbic acid products currently on the market have a pH value of only 2.5–3.5-an acidity level comparable to lemon juice. When consumed in large doses, approximately 20% of users experience stomach discomfort, acid reflux, or even heartburn.
Sodium Ascorbate, however, operates on a fundamentally different principle. Through the "buffering" action of sodium ions on Vitamin C, it raises the pH level to a neutral to slightly alkaline range of 7.0–8.0, thereby eliminating-at the root-any irritation to the gastric mucosa and tooth enamel.

Benefits of sodium ascorbate powder
Provides a Low-Acidity Source of Vitamin C
Sodium ascorbate is the sodium salt form of Vitamin C; with a pH value close to neutral, it is significantly less irritating to the teeth and the mucous membranes of the digestive tract compared to ascorbic acid.
Supports Normal Immune System Function
Vitamin C participates in the activation and protection of immune cells, helping to maintain the body's normal immune response.
Involved in the Normal Synthesis of Collagen
Vitamin C serves as an essential cofactor in the hydroxylation reactions required for collagen synthesis, thereby supporting the health of the skin, bones, teeth, and blood vessels.
Helps Enhance Iron Absorption
Vitamin C reduces ferric iron (Fe³⁺) to ferrous iron (Fe²⁺), thereby promoting the absorption of non-heme iron found in plant-based foods.
Supports the Body's Antioxidant Defense System
Vitamin C is a water-soluble antioxidant that helps protect cells from the effects of oxidative stress.
Application Fields
Dietary Supplements
High-dose vitamin C tablets, capsules, chewables, powdered drink mixes, and immune support formulas.
Food & Beverage Industry
Antioxidant preservative (E301) extending shelf life; vitamin C fortification in fruit juices, functional beverages, canned foods, dairy products, and protein powders.
Meat & Poultry Processing
Color stabilizer accelerating nitrite reduction to nitric oxide for stable red color in cured meats; prevents nitrosamine formation.
Pharmaceuticals
Vitamin C source in injectable formulations, osmotic laxatives for colonoscopy preparation, and oral medicinal products.
Cosmetics & Personal Care
Topical formulations for collagen synthesis, skin brightening, anti-aging, and wrinkle prevention without causing acid burns or irritation.
Animal Feed
Nutritional additive promoting growth and health in poultry, swine, aquaculture, and livestock; also used as a preservative in feed formulations.
Production Process
Product Quality Advantages

FAQ
Q: What is the difference between Sodium Ascorbate and standard Ascorbic Acid?
A: Standard ascorbic acid has a low pH (2.0–3.0) and a very tart, acidic taste that can cause heartburn or gastric upset, especially at higher doses. Sodium ascorbate is chemically buffered with sodium, resulting in a neutral pH (7.0–8.0) that is significantly gentler on the digestive system while providing equivalent vitamin C benefits.
Q: How much sodium does Sodium Ascorbate contain?
A: Sodium ascorbate provides approximately 11% sodium by weight (111 mg of sodium per 1,000 mg of sodium ascorbate, which contains 889 mg of ascorbic acid).This should be considered by individuals monitoring their sodium intake.
Q: Is Sodium Ascorbate GRAS approved?
A: Yes. Sodium ascorbate is listed on the FDA's list of generally recognized as safe (GRAS) substances.As a food additive, it has the E number E301 and is approved for use in the EU, USA, Australia, and New Zealand.
Q: Can it be used in liquid formulations?
A: Absolutely. Sodium ascorbate is highly soluble in cold water (approx. 62 g/100 mL at 25°C), making it ideal for liquid beverage fortification, brines, and ready-to-drink formulations.
Q: How's shipping handled?
A: We ship globally by express, air, or sea-pick the speed that matches your plan (and your patience).
