Zinc supplementation has emerged as an important element of choice for the management of Covid-19 symptoms along with anti-infective and other antiparasitic drug, according to Dr. Scott Read, Senior Lecturer, School of Medicine at Western Sydney University, Australia.
Dr Scott also recommends prophylactic use of zinc may be in a lower dose of 20mg improves systemic zinc levels but higher dosage is always beneficial in acute infections. “Zinc deficiency has been associated with an increased susceptibility to infectious diseases, including viral infections,” Dr. Scott said.
Studies have shown that the zinc status of an individual is a critical factor that can influence immunity against viral infections.
He further adds, “Zinc, recently has generated a lot of excitement as one of the promising candidates to reduce the severity of Covid-19 infection. Several published observations are the reasons why there is a global enthusiasm that zinc therapy could be a possible therapeutic option. However, the biggest challenge in realizing the therapeutic value of zinc is lack of understanding of optimal dosage of zinc supplementation.”
The right amount of zinc, that is, 50 mg, which of course is available in few brands, that can be counted on fingertips, would not only allow zinc to achieve its therapeutic potential against Covid-19 but also could circumvent the confounding multiple responses & efficacies associated with insufficient dosage intake of zinc, offered by majority of the conventional brands available in the market.
In India currently few brands are available with 50mg dose strength such as Zincolife, Aarzin etc. 50mg zinc with its unbeaten role as an adjunct therapy for Covid-19 and advantages such as lack of toxicity, low cost and ease of availability could be rapidly implemented clinically.
Even in present scenario, governments of Uttar Pradesh, West Bengal, Maharashtra, and Assam have already included Zinc along with other nutraceuticals, anti-infectives, corticosteroids & antiparasitic, etc drugs in their protocol for the management of Covid-19.
Dr. Scott cited several studies in support of the effectiveness of zinc 50mg daily in cases of SARs-CoV2 or coronavirus.
Another research published in Clinical Immunology Journal, Consumption of up to 50mg Zinc per day may provide a protective role against the Covid-19, likely by improving the host’s resistance against viral infections.
Dr Scott concludes, “In nut-shell, to guard people at masses and to protect those who came in close contact with Covid-19 patients as well as in the treatment of asymptomatic and mild Covid patients” zinc “but at the right dose” plays pivotal role in alleviating the symptoms.
