Vitamin D deficiency is a major risk factor for catching COVID-19, being sick enough to need hospitalization, and dying from it. Don’t take that risk, please. Vitamin-D comes from sunshine entering superficially into the skin, and causing a photochemical reaction that creates vitamin-D. The great majority of people who do not work outdoors are deficient in vitamin-D, mildly, moderately or severely. Black people in New York and in Northern Europe, rich and poor alike, were some of the most deficient in vitamin-D last spring. Do you recall how that went?
Above and below the sub-tropics, the winter sun is too weak to produce vitamin-D, even if you can bare your skin at midday. Vitamin-D supplementation is cheap, safe and effective. Somebody may have already screamed, “Don’t take too much” at you. I agree. What’s a good dose and what’s “too much”. The dose I have taken for over a decade is 1/8 of 1 milligram per day. That is 125 micrograms, or 5000 units. 1 mg of vitamin-D3 is 40,000 units. Weird, right? 1 mg sounds like nothing, and 40,000units sounds like WAY TOO MUCH.
Zinc has been known since the 1990s to shorten the severity and duration of “some common colds”, namely those caused by coronaviruses. The studies used treatment dosages of roughly 150 to 250 mg per day of zinc, usually as lozenges, spread out through the day in divided doses. What zinc does inside a cell, infected by a coronavirus, is to reduce its ability to make more coronaviruses. That is ideal in the period of exposure and early infection, to reduce viral replication enough to let the innate immune system keep the virus from getting the better of you. Take 50 mg per day of oral zinc, as a tablet or lozenge, together with 250 mg of Quercetin, also readily available, a natural product of onions and other vegetables. Quercetin helps zinc get into cells, which is where zinc is effective. (It’s really hard to eat enough onions to get that much.)
It is good to buy an inexpensive pulse oximeter and get to know what your usual baseline is. For most people it is 97% to 99% saturation. It will be lower if you live at high altitude. Dropping 2 points from normal means your lungs are not working right. It likely means COVID Pneumonia, if you have a positive test, already. Some people will read a little higher than they really are, so if you read a little low (95%), and feel short of breath, you may actually need oxygen. You may need to go to a hospital. If your pulse oximeter reads 93% or below, you really should be promptly evaluated at a hospital. You might need to check in.Treat Your Own COVID – The Automatic Earth
