Is Sonic Blueberry Add-In High in Histamine?

Sonic Blueberry Add-In

Low histamine

This blueberry add-in is low in histamine, made simply from sugar, blueberry puree, and xanthan gum.

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 fruit add-in made of sugar, blueberry puree concentrate, and a little xanthan gum for texture.

No histamine drivers flagged — blueberry is not a classic liberator, and nothing here is aged or fermented, so the level stays low.
Just fruit and sugar — the puree carries the flavor and the xanthan is only a thickener, so the whole add-in reads as low.

This is a friendly, real-fruit way to flavor a drink without pushing the histamine up.
