Most of the article did not make sense and was repetitive, I don't think this is long enough but got to summarize up to:

Studies have shown zinc supplements improves immune system function and resistance to infection with its anti-inflammatory and antibacterial properties. Research suggests that this could also explain why taking a zinc supplement at the beginning of a cold can reduce its severity and that it can reduce its duration even before the cold starts. Especially during a time of a pandemic, taking zinc supplements can provide an individual with additional protection against Covid 19.

In addition, adequate zinc intake is crucial for older adults, as there is a high risk of impairment of immune system function, heart disease, diabetes, cancer and other health problems.
