Sonic Green Tea Concentrate

Moderate histamine

This is a green tea concentrate, and it lands moderate because green tea is a listed DAO inhibitor.

Fast food is cooked in batches and held warm rather than made when you order it, so it is rarely as fresh as something cooked at home. That matters here because histamine builds up as protein foods sit, which means the same item can affect you differently depending on how long it waited.

This is a green tea concentrate made from green tea essence and extract with a touch of citric acid and magnesium citrate.

  • Green tea — it sits in SIGHI's restricted column and is marked as a possible DAO blocker, so it may slow the breakdown of histamine from the rest of your meal.

  • The other additives — the small amount of citric acid and magnesium citrate are not the driver here; the green tea itself sets the moderate rating.

For a gentler drink, a caffeine-free herbal option keeps the tea out of the picture.
