Sounds good. So then why isn't the CDC telling people to zinc up?
Morons. They screwed up the whole pandemic response and we wasted a whole month. They are also probably biased against a simple supplement. In America everything has to be a drug. Read the second post in this thread. Zinc's effect is well known for the rest of the world.
Personally I have been surprised that for people having the virus and going through it at home there is no advice given. "Take a rest and drink fluids." This is it. This is the most scientific advise what America came up with. No taking vitamins or some anti-viral supplement, just drink fluids.
Generally speaking, they never push simple and cheap solutions. Did they ever say, lose weight, give up smoking? (before you get the virus) They are not promoting to boost your immune system, although we still have time, before we get the virus. This is one reason to try to push out the inevitable, so you can get your body in the most optimal state when you get hit by Covid 19.
I was also surprised the government and/or CDC didn't do commercials about how to wash hands or distance yourself MUCH EARLIER. Information costs nothing but could save lives, yet it was up to every channel and program if they spread any kind of helpful info. Finally about 2 weeks ago I started to see government ads. Again, they wasted 3-4 weeks easily.
Now why is that, that is anyone's guess. Was it the anti-science culture what Trump promotes? Was it just plain old stupidity? Anyhow, that is politics, this is the science subgroup.
