Anybody else using Lactoferrin in their strategy and why? This was at one time on my list for antiviral stuff, but something about it made me hesitant to use it even though it has good antiviral activity in theory. Maybe it was the iron that made me wary of it, I don't remember.
I'm using it.
1) It interferes with the virus ability to attach to host cell membrane by blocking HSPGs and this M protein in the virus is partially used by the virus to navigate to an ACE2 receptor where the S-protein enters.
2) Expression of the Lactoferrin gene was the highest upregulated gene in SARS-CoV1 cohort of PBMCs.
I am still looking into exactly how Lactoferrin works. I think it upregulates NK cells, which would be huge, but the actual efficiency (cytotoxicity) of those cells may be questionable. Upon symptoms, I intend to dose 2 grams per day in two equally divided doses. I take nothing now.
