Usage

Functions of Sodium Pantothenate

Sodium Pantothenate, the sodium salt form of Vitamin B5, serves the following key functions:

‌Nutritional Supplement‌: Acts as a Vitamin B5 supplement, participating in energy metabolism and maintaining normal physiological functions. Widely used in food, health products, and pharmaceuticals.

‌Medical Applications‌: Employed in long-term replacement therapy for hypothyroidism, improving symptoms through metabolic regulation.

‌Extended Applications‌: Utilized in cosmetics as a moisturizing and reparative agent to enhance product efficacy.

China is the world’s leading producer of Vitamin B5 (D-calcium pantothenate) and intermediates (e.g., D-pantolactone). In 2023, China’s D-calcium pantothenate capacity reached nearly ‌30,000 metric tons‌, dominating global supply. Sodium Pantothenate, as a derivative of pantothenic acid, directly benefits from upstream raw material capacity expansion and mature production technologies.

China’s factory focuses on eco-friendly processes (e.g., ‌bio-enzymatic synthesis‌) to replace traditional chemical synthesis, not only reducing pollution from cyanide-containing wastewater, but also improving capacity utilization rates.
