Product Introduction
Sodium Ascorbate DC99 is a directly compressible, high-purity sodium salt of L‑ascorbic acid. In aqueous media, it dissociates into ascorbate anion and sodium ion; the ascorbate moiety acts as the biologically active form.
1.Redox & Antioxidant Mechanism
Ascorbate functions as an electron donor, directly scavenging reactive oxygen species (ROS/RNS) including peroxyl radicals, superoxide, and hydroxyl radicals. It regenerates oxidized vitamin E back to its reduced, active form, sustaining lipid‑phase antioxidant defense.
2.Enzymatic Cofactor Role
It serves as an essential cofactor for Fe²⁺‑dependent dioxygenases, supporting prolyl/lysyl hydroxylases for collagen maturation, TET enzymes for epigenetic regulation, and dopamine β‑hydroxylase for neurotransmitter synthesis.
3.Physical & Formulation Properties
Neutral pH minimizes gastric irritation compared to acidic ascorbic acid. DC99 grade is engineered for direct compression with consistent flowability and compressibility, supporting high‑efficiency tableting without wet granulation.

Frequently Asked Questions
What is the difference between Sodium Ascorbate DC99 and regular ascorbic acid?
-
Sodium Ascorbate DC99 is a neutral pH sodium salt of vitamin C, whereas ascorbic acid is acidic. DC99 is gentler on the stomach, more stable, and suitable for direct compression and high‑dose supplementation.
What does "DC99" stand for?
-
DC99 = Direct Compression 99%. It indicates the product is designed for direct tableting with ≥99% assay, high flowability, and strong compression properties to streamline manufacturing.
Is Sodium Ascorbate DC99 suitable for sensitive stomachs?
-
Yes. Its neutral pH minimizes gastric irritation compared to acidic ascorbic acid, making it well‑tolerated for daily and high‑dose use.
What is the shelf life and storage?
-
24 months when stored sealed, dry, cool, and away from direct light. Avoid moisture and high temperature to preserve stability.
Can you provide custom particle sizes and packaging?
-
Yes. We offer custom particle distributions and flexible packaging (1 kg–25 kg drums), supporting OEM specifications and bulk orders.
