Zinc is an essential micronutrient factoring in anti-inflammatory and antioxidant functions. In vitro, zinc deficiency is related to enhanced IL-6 and IL-1β production, thereby translating to a pronounced inflammatory response. Hence, there are various ongoing studies to evaluate the role of zinc in antiviral immunity. The recommended dietary allowance for zinc is 11 mg/day in men and 8 mg/day in women. There are concerns for impaired intestinal absorption of copper and suppression of the immune system with long-term intake of high-dose zinc. [57]
