We’ve been on the Nutraceutical protocol for the last 2 years, it’s not a cure, but immune boosting help, C, D, K2, Magnesium, NAC, Zinc, Quercetin, Melatonin. We both got Omi on February, I’m 59, but hardly was affected, just loss of smell for 3 weeks. My wife had it worse, but still on the mend after 3 days of fever and malaise. She had brain fog, and loss of smell and taste for about 6 weeks. We credit the supplements for limiting the illness and effects.
