It doesn’t start out great:
> According to its co-president, Paul E. Marik, the group has a shared interest in vitamin C.
Apparently they’ve pushed a lot of unproven and not-so-great stuff:
> The group initially started promoting Marik's discredited sepsis treatment protocol as a treatment for COVID-19, and in April 2020 it circulated press releases promoting vitamin C, heparin, hydroxychloroquine and other drugs, before pivoting to ivermectin promotion in October 2020.
A former member of the group expressed skepticism about their approach and resigned over his concerns (there were only 10 people to start with)
> In August 2021 one doctor, Eric Osgood, resigned from the FLCCC because the group "may be contributing to people making the choice not to get vaccinated". Osgood commented: "If you're going to have a page that's dedicated to 'How do you prevent yourself from getting COVID?' that page can't not have vaccines at the top of it".
And apparently one of their members did this:
> In 2021, Fred Wagshul, a member of the FLCCC, prescribed ivermectin for a patient in a hospital in Ohio where he did not have admitting privileges.
Granted, I guess if you were cool with fringe ideas like Vitamin C cures coming into this, none of what I quoted here will change your mind. But this doesn’t strike me as a group I’d trust, even though they have a well-designed website.
