Get Orthomune. Two caps daily — a great combo supplement (in addition to Ivermectin)

Certainly convenient having all those in one cap (actually 2 — one serving), but I take all the same things separately and higher doses of quercetin and NAC.
It’s also missing the bromelain which aids in the absorption of quercetin and other synergistic benefits the two give when together. The manufacturer skimped on that.
