Additional Notes

Approximately 140,000 tonnes of vitamin C are manufactured annually globally, with China accounting for over 85% of supply. The chemical is identical to natural vitamin C but produced via a two-step process (Reichstein synthesis followed by fermentation, or entirely via fermentation). The 'natural' vs 'synthetic' vitamin C debate is nutritionally irrelevant — the molecule is chemically identical.
