The nanotech stuff I'm agnostic about; it seems quite hard to believe, but then so does so much else regarding covid. I've not had a chance to watch the vid yet, but regarding blood coagulation, a mid western doc has touched on this stuff, talking about zeta potential of the blood (a measure of its stickiness, I think); she notes that one thing that can be done to increase that zeta potential is to simply eat chia seeds. One of those no risk, low cost solutions.
