Stevia

Stevia sweetness comes from leaf compounds called steviol glycosides — extracted without fermentation or aging.

• Why it's generally well tolerated — there's no known mechanism by which stevia triggers histamine release or interferes with histamine breakdown

• Watch for blends — stevia is often combined with erythritol, inulin, or other fillers; the stevia itself is low risk, but other ingredients in the blend may affect tolerance differently

Pure stevia extract or single-ingredient stevia is the simplest choice if you want to keep things low risk.
