Dipotassium guanylate

Dipotassium guanylate is notable for histamine. Clear on tyramine, salicylate, sucrose, FODMAPs, lactose, oligosaccharides, sorbitol, fructose, nickel, oxalates and gluten.

Dipotassium guanylate contains only low levels of histamine. Dipotassium guanylate is a nucleotide flavour enhancer extracted from yeast or from fish - both among the most amine-rich raw materials there are. Purification separates the nucleotide from the amines, so the additive itself carries none; the origin is why it appears on elimination lists, and why it usually sits beside yeast extract on a label. Blackwell measured yeast products, not this additive. Amounts vary by brand and recipe, so always check the label of the exact product.
