95% of the world's vitamin C is produced in China. Here's a factual comparison.
The Global Ascorbic Acid Market
Global production: ~150,000 tonnes/year. China: 95% of production.
In Europe, one major producer remains: DSM (dsm-firmenich). Its Quali-C brand is the last European bastion.
Technical Comparison
| Criterion | China origin (typical) | Europe origin (DSM) |
|---|---|---|
| Purity | 97–99% | ≥99,7% |
| Reference standard | BP/CP or internal standard | European Pharmacopoeia (Ph. Eur.) |
| GMP Certification | Variable (China GMP) | EU GMP (EMA inspected) |
| Heavy metals control | Per applied standard | <0.5 ppm Pb (ICH Q3D) |
| Residual solvents | Not always tested | Controlled (ICH Q3C) |
| Raw material | Corn (often GMO) | Certified non-GMO |
| Traceability | Multi-intermediary | Direct manufacturer to distributor |
| Auditability | Complex (distance, language) | Standard European audit |
Manufacturing Process
Both use the modified Reichstein process. Difference lies in production conditions.
DSM: two-step fermentation, multiple crystallization. Purity consistently >99.7%.
The Standards Question
Multiple pharmacopoeias exist. Ph. Eur. imposes the strictest limits.
Chinese manufacturers can produce Ph. Eur. compliant acid. But most target less demanding markets.
Traceability and Supply Chain
Chinese chain: often 3-5 intermediaries. Potential opacity.
Direct European sourcing: 1-2 links. Identified and auditable manufacturer.
Why the Price Gap
European vitamin C: 2-4x more expensive. Extra cost: a few cents per daily dose.
Our Choice
Exclusively European L-ascorbic acid (DSM), Ph. Eur. compliant, non-GMO certified, direct traceability.
The origin of your vitamin C is not a logistical detail. It determines what you put in your body every day.
