Purity Metrics (Third Party Verified)

When sodium ascorbate is implemented at higher intake levels, purity becomes dose-dependent exposure. PUR-C™ publishes representative third-party verified outcome data to provide transparency regarding key purity parameters.
Endotoxin Activity (EU/g)
PUR-C™: 0.154 EU/g Commercial sodium ascorbate sample evaluated: 1.50 EU/g Observed difference: approximately 9–10× lower endotoxin activity in the tested comparison.
Microbial Bioburden (CFU)
PUR-C™: Aerobic <1 | Anaerobic <1 | Fungal <1 Commercial sodium ascorbate sample evaluated: Aerobic 324* | Anaerobic 31 | Fungal 6 Observed difference: ≥99% lower total bioburden in the tested comparison. Aerobic count reported by laboratory as an estimate due to high colony density.
Quality Framework
PUR-C™ applies a three-phase quality structure:
  1. Raw material qualification under proprietary specifications
  2. Controlled manufacturing with in-process oversight
  3. Independent third-party verification prior to batch release
Laboratory identities, analytical methodologies, internal specifications, and process controls remain proprietary. Comparisons reflect tested market samples and are not intended to represent all products in commerce.

Enhancing Bioavailability with Sodium Ion Co-Transport

Sodium Ascorbate significantly enhances bioavailability through the vital role of sodium ions in the function of sodium-dependent vitamin C transporters (SVCTs) on cell membranes. These transporters, particularly SVCT1 and SVCT2, use the energy from sodium ions to move vitamin C into cells against its concentration gradient.

The sodium ions in Sodium Ascorbate are crucial for triggering conformational changes in SVCTs, which are responsible for vitamin C uptake. SVCT1 is primarily involved in the absorption of vitamin C in the intestines, while SVCT2 distributes vitamin C to various tissues throughout the body. Sodium ions facilitate the transport process by providing the necessary energy for SVCTs to function effectively. Without sufficient sodium ions, SVCTs cannot transport vitamin C efficiently, potentially leading to deficiencies and suboptimal cellular absorption.

SVCT1 and SVCT2 rely on sodium cotransport to bring vitamin C into the cells. Sodium ions bind to the transporters, causing them to change shape and allowing vitamin C to be transported into the cell. This process ensures that vitamin C is absorbed efficiently, maintaining optimal physiological levels.

By providing both vitamin C and the essential sodium ions required for its transport, Sodium Ascorbate ensures efficient vitamin C uptake. This dual functionality enhances cellular absorption and maximizes the bioavailability of vitamin C, leading to better clinical outcomes and improved patient health.
