Used as a dietary supplement to support immune system function, address vitamin C and zinc deficiencies, and potentially reduce the severity and duration of common cold symptoms. May also be used as an adjuvant in wound healing and general wellness support.
Vitamin C (ascorbic acid) acts as an antioxidant and supports immune cell function and collagen synthesis. Zinc is an essential mineral that plays a critical role in immune response, protein synthesis, and wound healing. Together, these nutrients work synergistically to support the body's natural defense mechanisms.
Generally well-tolerated but may cause gastrointestinal upset (nausea, diarrhea) in some individuals, especially with high doses. Zinc should not be taken long-term at high doses without medical supervision. May interact with certain antibiotics (tetracyclines, quinolones) and copper absorption. Consult a healthcare provider before use if pregnant, nursing, or taking other medications.
