Who benefits financially from mandatory synthetic folic acid fortification of the UK food supply?

Not a rhetorical question. Actual answer below. 🧵 Synthetic folic acid is made at scale by:

→ DSM-Firmenich (Dutch-Swiss)
→ BASF (German)
→ Chinese manufacturers

Pennies per dose.

Mandatory fortification = guaranteed demand across every UK flour product. Indefinitely.

No marketing needed. The government does it for them.

From late 2026, synthetic folic acid will be added to almost every loaf of bread, every pack of flour, every pizza base in the UK.

No opt-out. No label warning. No conversation about who it might harm.

Here's what the headlines aren't telling you. 🧵 The UK government's folic acid fortification mandate applies to all non-wholemeal wheat flour.

The stated goal: reduce neural tube defects in pregnancies.

A worthy aim. But the method — adding synthetic B9 to the food supply for 67 million people — is a blunt instrument with real clinical consequences.
