Many folks fell for that kind peddling, myself included, but I didn't buy into everything they said or sold. I wised up to them when they said that Quercetin would prevent the onset of Covid, yet just a couple months into taking it I got it, and pneumonia with it. Afterwards I threw it all away except for Vitamin D3 (which my doctor always suggested I take, Covid or not), B12 for my feet and a multivitamin. That's it.
Their website has poor scores and reviews on sites like ‘Trustpilot’.
(I was kind of surprised to see Dr. Drew involved with this.)
