Ingredient profile
The Science
Description
Characterized by a stout, thick white stem and a small tan cap, the King Oyster is rich in ergothioneine, a potent cytoprotective antioxidant. Its dense fiber structure acts as a functional prebiotic, slowing glucose absorption and supporting gut health. Remarkably meaty and succulent, it offers a mild, sweet, and savory flavor profile that transforms into a savory delicacy when sliced and seared for functional meals.
