Metallic Taste

Metallic taste, also known as dysgeusia, is a taste distortion characterized by a persistent metallic, tinny, or otherwise unpleasant taste in the mouth. It can occur independently or be associated with other symptoms. In the context of zinc gluconate supplementation, it is believed to arise from the interaction of zinc with taste receptors or through the release of metallic ions in the oral cavity. The taste is usually perceived on the tongue and can alter the perception of food and drinks. The severity can vary from a mild annoyance to a significant impairment of the sense of taste.
