I've been following Dr Berg since the start of the coof fiasco. His videos helped me learn about the benefits of some really lesser known supplements/remedies to boost immune system function and fight infection; ie, NAC, Quercitin, Ivermectin, and of course the zinc, vitamins C, K2, phosphatidyl choline, etc.
I never fell for the egg, beef, butter, milk scare porn that's been the FDA mantra for 50+ years, thankfully.
It's interesting that the same foods that help make people strong are the same foods that keep people healthy and strengthen immune system function and response.
