Just to make it clear, any responses I get, will not be taken as "medical advice", just good practice for everyday health.

I got some Vitamin B12 to add to my regimen of supplements that I take to guard against COVID (or whatever this thing is, that is making people so sick).  I presently take not only a senior men's multivitamin, as well as a male health supplement (Ageless Male Max, though not for any "virility" benefits, as I live celibately as a divorced husband without annulment) and mega-doses of Vitamin C, Vitamin D, zinc, and selenium. 

The bottle says each tablet has 1000 mcg.  Regardless of what the bottle says, what would be a recommended dosage?  Anyone know?

My father (who had been a physician's assistant and Army medic) gave my grandmother a B12 shot once a week (she couldn't have weighed 90 pounds soaking wet, tiny little woman, little Scots-Irish spitfire not to be trifled with), and she lived to the age of 89.   I always remind my son that he may have to put up with me for the next 30 years.

I would add turmeric to your diet, it has many properties.

Also kirfir is a very very good probiotic. A health expert who is 91 thinks it's what keeps him going.

God bless

I've considered turmeric (which gets pronounced two different ways, "TUR-murick" and "tur-MARE-ick"), but I take so many supplements as it is, I really want to keep additions to a minimum.  I do like kefir (alternate spelling) --- that sounds Arabic (as well as like a rude word for black South Africans) but the drink actually originated in the Caucasus by way of Russia.

I take, among other things, 5 grams of Vitamin C per day.  It can affect one's digestion.  (Let's just say that I have no problem "staying regular", beyond that would be TMI.)  I was told that 20 grams would be better, to which I protested that there is no way my stomach would tolerate 20 grams.  That'd be a case of "the cure being worse than the disease".

Incidentally, I had another Russian drink once, called kvass --- it tastes like sour beer, and it will "plug you up" like nobody's business.  Like drinking radiator seal.  Never again.

Been taking tumeric in liquid form for about a year and I’m convinced it is a valuable supplement. Like others who have responded, lots of C, also zinc, resveratrol (which is  found in red wine) and magnesium and plenty of natural vitamin D being I live in Florida and spend a lot of time outside.I  recently added HCQ for now as well as I’m 60years old and so far, remaining healthy Thank God! Finally, I enjoy fine tequila and believe it is a viable supplement…though I’m sure there will be some disagreement on that but I believe in it
