Disodium-5′-guanylate and the Vegetarian Diet

Sodium guanylate is the sodium salt of guanylic acid and is primarily used as a flavor enhancer in the food industry. It is often found in conjunction with monosodium glutamate (MSG) to enhance savory flavors in foods. Although naturally occurring in some foods, commercial sodium guanylate can be synthesized from yeast extract or derived from animal sources, such as fish, making it unsuitable for strict vegetarians and vegans unless the source is specified.
