Disodium guanylate (E627) is the disodium salt of guanylic acid (GMP), a nucleotide naturally present in dried mushrooms, seaweed, and certain fish. It is used as a flavor enhancer with even greater synergy with glutamates than disodium inosinate. The combination of GMP and IMP (5'-ribonucleotides, E635) is one of the most potent umami enhancement systems available.
Dramatically potentiates umami flavors in processed foods, allowing reduced MSG use; used in combination with MSG and disodium inosinate in snack seasonings.
Considered safe at food use levels. As a purine nucleotide, it raises the same gout/hyperuricemia concerns as disodium inosinate. Commercial disodium guanylate is often derived from fish (sardines) or yeast, making it non-vegan and non-vegetarian in most commercial applications. People with gout should be aware of cumulative purine intake from these additives.

Naturally occurring in dried shiitake mushrooms and nori seaweed, which provide the same GMP without additive labeling.
Often derived from fish or yeast. Always check with the manufacturer for vegan-specific sourcing.
Both are nucleotide flavor enhancers; GMP (guanylate) is slightly more potent in its synergy with glutamates. They are typically used together.
On chips, noodles, and seasonings — often in the fine print near MSG or as part of 'contains: soy, MSG.'
Yes, at typical food additive levels. Individuals with gout should limit purine-containing additives.
