IHOP Pistachio Syrup

Low histamine

IHOP's Pistachio Syrup is low in histamine, a simple sweet flavoring syrup with no flagged drivers.

Most of this is cooked to order, which is the best case for histamine. Even so, a restaurant kitchen preps ahead and holds things warm through a service, so freshness varies more than it would at home. The rating above comes from the chain's published ingredients. If a dish is borderline for you, asking how it is prepared tells you more than the menu does.

This is a flavored syrup built mostly from cane sugar, sea salt, spirulina for color, a touch of citric acid, xanthan gum, and turmeric.

  • Sugar-based syrup — the backbone is pure cane sugar with color and thickener, none of which carry histamine, so the whole thing stays low.

  • The small extras are mild — the citric acid, spirulina, and turmeric are here in tiny flavoring amounts and none are flagged as histamine drivers.

This is one of the gentler add-ons on the menu, so pour it over pancakes without much worry.
