Why no push on supplements?

Because there is no scientific evidence to prove that supplements prevent COVID or death. Hell, if you go to GNC which only sells supplements, nearly every one in the store says “not FDA approved” or “health effects have not been measured in a scientific study”

We can agree that 98% of the deaths associated with COVID are a result of an underlying health condition I.e Obesity, heart disease, liver disease, diabetes etc. but the CDC literally testified before Congress that they classify COVID deaths as ANYONE who was infected with COVID at the time of death as a COVID death. They have literally classified car crash victims as COVID deaths because they had the virus. They also testified that less than 2% of all deaths are from the virus itself.

If you have antibodies, you have had COVID or you’re fully vaccinated. But your antibodies don’t continue to rise from the vaccine 6 months after fully vaccinated. They only do that if you have had the virus

Just because you can take them doesn't mean 1. they work on you. 2. Are what the label say the strength and contents are what's in them. Or that you don't have serious health issues. Many of the dead in nursing homes were not obese.

Ok well I I'm kinda round since I left the military. I received the 2 Phizer shots last year in March April at VA. The second one knocked me for a loop. I've had off and on vertigo ever since. One daughter to keep her job in WA state got the Johnson which put her in the hospital 5 days. Son in the Army got both Phizer. He generally maxes the APFT, he had to take the "new" APRT two weeks later, he blames not maxing it on the shot. Probably. Other daughter in WA had to get the shot and her husband did also. But 6 weeks ago he caught the Covid, they just told him to go home and tough it out. He was a breath away from dying when my daughter finally found someone to administer the antibody infusion to which he started breathing better within the hour, and is full recovered.
There is an understanding that if your low on a certain element a supplement could be used to replace that but you have to be tested for each element. Just to take something could cause further imbalance of something else. Some supplements won't absorb well without another element so taking too much of something may not work at all because the other element it works with isn't there or is low. VA has me on a D3 supplement they provide. I also take a Cal-Mag-Zinc and C and a multi B complex as per doc.
So in the past 120 days, I have lost 4 good friends to Covid that were fully vaxed that caught Covid and died within 3 days. One with shot that barely made it only because of persistence. I have also 7 friends and relatives that have not been vaxed and caught it, yet survived and are doing fine. Pick your poison.
Last March my daughter in Montana caught it tested positive, yet her husband and two kids tested negative. He just started a new job and his boss said if you test positive I'll pay you to be off. Second test, he and the kids are still negative, though they were worse off. She was still positive. He got up and went to work in spite of it all. They are fine now. And they are non vaxers. They own their home and everything else plus home school, so if it becomes mandatory there, they will just go off grid.
This one size fits all is like the oversized one size fits all sweater. You may be able to put it on but it will fit everyone differently. Lets say you go to the doctor to get BP meds. They're going to look at history, weight, overall health, allergies before prescribing something. There's over 30 different varieties of BP meds.
