Sodium sulfite
Other names sodium sulfite, E221
Sodium sulfite: high in histamine. If you're sensitive to any of these, check it against your profile before eating.
Intolerances
- Histamine (+liberators / DAO inhibitors)High
Sodium sulfite is the plain sodium salt of the group, and sulfites are not documented as inhibitors of DAO, the enzyme that clears histamine. Sulfites are here because their intolerance looks like histamine intolerance and travels in the same foods — not because a mechanism links them. It supplies no histamine, and the family shares no mechanism here - only the foods and the elimination protocol.

Frequently asked questions
Which intolerances does sodium sulfite affect?
Sodium sulfite is notable for histamine. Clear on tyramine, salicylate, sucrose, FODMAPs, lactose, oligosaccharides, sorbitol, fructose, nickel, oxalates and gluten.
Does sodium sulfite contain histamine?
Yes — sodium sulfite is high in histamine. Sodium sulfite is the plain sodium salt of the group, and sulfites are not documented as inhibitors of DAO, the enzyme that clears histamine. Sulfites are here because their intolerance looks like histamine intolerance and travels in the same foods — not because a mechanism links them.
