Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Zinc supplementation during cancer treatment is supported by some scientific evidence, particularly for its role in reducing certain side effects of chemotherapy and radiotherapy. Zinc is an essential trace element involved in immune function, wound healing, and cellular repair, which are all relevant in the context of cancer therapy. Multiple studies have investigated zinc’s role in managing oral mucositis, a common and painful side effect of chemotherapy and radiation, especially in head and neck cancers. Some randomized controlled trials and meta-analyses suggest that zinc supplementation may reduce the incidence and severity of oral mucositis. For example, a 2021 meta-analysis published in Supportive Care in Cancer found that zinc supplementation reduced the severity and duration of oral mucositis in patients undergoing radiotherapy. However, the evidence is not universally strong or consistent across all side effects or cancer types. There are concerns about excessive zinc intake potentially interfering with other trace elements (such as copper) or immune responses. Additionally, zinc supplementation does not treat the cancer itself but may help mitigate specific treatment-related side effects. Major clinical guidelines do not recommend routine zinc supplementation for all cancer patients but suggest it may be considered for specific indications like mucositis, particularly when dietary intake is insufficient. In summary, while not universally endorsed, zinc is used with some scientific backing for reducing certain side effects of cancer treatment, primarily oral mucositis, but its use should be individualized and monitored.
