That is one reason I started taking Zinc, along with Vitamin D, C, and I have full prescription of Ivermectin I can fall back on if necessary.
I hate these “studies” because once they’re published and the general public gets wind of them, you can’t afford to buy the damned product anymore. Supply is overwhelmed by demand, the cost skyrockets, hoarding takes hold, and then it’s hello scarcity. Always some SOB somewhere with a lot of money in the market who needs to get richer quicker, so they bankroll studies like this to spike global demand. Could even be foreign money doing it.
