According to a private online group of Alberta Health Services workers against mandatory vaccinations, there are many healthcare employees who remain not fully vaccinated. The group’s members are sharing information of supplements to keep their immune systems healthy while on the job, which include the use of high dose vitamin C, zinc and a supplement known as N-Acetyl-L-Cysteine (NAC). It is getting increasingly hard to get your hands on NAC in the U.S., but here in Canada, it’s as easy to reach as going to your local health store. We spoke with a local retailer to explain why it is such a popular product among some healthcare workers. According to a report from National Center for Biotechnology Information in the U.S., consumption of NAC ‘may suppress SARS-CoV-2 replication and may improve outcomes if used timely.’ According to Health Canada, two Canadian companies that sell NAC were making false or misleading statements, claiming that NAC could mitigate, prevent or treat COVID-19.
