Vitamin D Can Fight Covid-19!

Vitamin D Can Fight Covid-19!

Vitamin D and the Immune System

Vitamin D is required for a properly-functioning immune system.

Individuals with deficient levels of Vitamin D have a higher probability of developing diseases related to a poorly-functioning immune system.

The level of Vitamin D, specifically 25-(OH)D3, needed is much higher than was realized 20 years ago when Michael Casparian, MD, and I wrote an article on Vitamin D. At that time, the optimal level of 25-(OH)D3 in a person’s blood was considered to be 30 – 40 ng/mL. However, new research has now shown that to achieve an optimal level that enables the immune system to fight off pathogens such as Covid-19, the level of 25-(OH)D3 must be at least 50 ng/mL.

The winter months in the Northern Hemisphere are when flu and Covid cases spike. January and February could be really bad months for Covid.

This is because it is impossible to achieve and maintain optimal levels of 25-(OH) D3 during the winter months in the Northern Hemisphere as the angle of the sun prevents UVB radiation from penetrating the ozone layer to activate pro-hormone D in bare, exposed skin. Sun-bathing in the winter in Chicago would be uncomfortable and useless for increasing your Vitamin D levels.

Eating several servings per day of oily fish like sardines will help raise your Vitamin D levels somewhat, but that is really the only food you could eat that would raise Vitamin D levels. The amount of Vitamin D3 you can get from other food sources is too tiny to help.

The best course of action during the winter months is to take a Vitamin D supplement that does NOT include calcium. Optimized Vitamin D levels maintain appropriate calcium regulation without taking supplemental calcium. Milk actually doesn’t do most bodies good. Excess calcium can create its own health problems such as weaker bones or kidney stones.

If you live in the Northern Hemisphere, it is highly probable that your levels of 25-(OH)D3 are far below the optimal level of 50 ng/mL. During the Pandemic, I have been taking 4000 IU/day of Vitamin D3. I will increase this to 6000 IU/day during January and February. I am also fully vaccinated with Pfizer, including a booster shot. And I wear a mask indoors or in crowds outdoors.

The Omicron variant is much more infectious than the Delta variant. As of this writing, we do not know how it compares in terms of disease and death, but it is best practice to do all we can to avoid any illness, however ‘mild’ it may be. A ‘mild’ case can still be debilitating.

Actions to take to minimize the possibility becoming ill with Covid or the Flu:

  1. Get vaccinated (and boosted).
  2. Wear a mask indoors and in crowds outdoors.
  3. Take a daily supplement of Vitamin D3.

Human Food and Agriculture

Dr. Anth Talks released several videos that form an important collection.  The topics discussed include what humans are meant to eat and how the development of agriculture created major changes to ecology, diet, and human health.

Those videos are collected in this post for ease of access and viewing.

White Privilege: What It Is and How to Incorporate the Topic into your Class Sessions

My article on White Privilege: What It Is and How to Incorporate the Topic into your Class Sessions was published by NISOD, an organization of community and technical colleges, on June 4, 2020.

I did a Webinar on White Privilege for NISOD on January 31, 2020.

Please contact me to arrange for a seminar or workshop on White Privilege for your organization and to receive a PDF of my article on White Privilege which includes links for further information and cases.


White Privilege: What Is It? Do You Have It?

White Privilege is a concept that causes angst and dissension.  However, it is actually simple and straightforward.  Let’s take the second question first: Do You Have It?  Yes. If you are white or perceived by others to be white, you have it.  So, What Is It?

Simply stated, White Privilege is the ability to live your life doing your ordinary, daily activities without having to worry that you might become a target.  If this is still unclear, here are several examples.

White Privilege is deciding to go shopping at an upscale department store and not being worried that you will be trailed by a security guard or intimidated into leaving because you don’t look like “our type of customer.”  Read about two such incidents that happened at Barney’s in New York City where the customers were not white.

White Privilege is being in a car accident, knocking on the door of a nearby house to request help, and not fearing that you will be shot through the door instead.  The white homeowner who shot and killed a black woman asking for help was later convicted of murder, but that was no consolation to the woman.

White Privilege is being a boy playing in a park with a toy gun and not having to worry that a police officer will drive up and kill you.  White Privilege is also being able to kill that child and not having to go to trial and be convicted of murder.  Instead, the officer was fired.  Later, he was hired by another police department in Ohio, but quit when there was a public outcry. 

White Privilege is being taken seriously as a medical professional during a medical emergency on a plane, even when you offer no proof, simply because you are a white male when the first physician to offer help is ignored because she is black.

Once that physician’s story received publicity, it was quickly shown that ignoring non-white, non-male physicians is not a rare event.

White Privilege is eating lunch with your girlfriends in the school cafeteria and laughing uproariously without having to worry that you and your friends will be dragged off to the office and strip-searched for drugs. Why else would you be laughing if you weren’t high?  The school denies ‘strip-searching’ although they do agree that the girls had to remove at least some of their clothes and that they were given a medical exam.  Governor Cuomo is investigating.  As someone who has an uproarious laugh, I am disturbed to think that laughing could be considered a sign of drug use.

White Privilege is being a man who loves cars, owns a really nice one, and never worries about being randomly pulled over by police officers who think a man like him could not/should not own a car like that.  Highly-educated, professional black men always have that concern in the back of their minds when they are driving.

Driving while black can be dangerous.

White Privilege is entering your home and never having to think that someone might call the police on you to accuse you of breaking and entering.  Even when a non-white person proves to the police that they are in their own home, they still risk being arrested.

White Privilege is a type of Power, even for those white individuals who think they are powerless.  White Privilege allows those perceived as white to shop, play, laugh, work, ask for help, drive a nice car, and feel safe in their home without worry or fear that they will be targeted, arrested, or even killed for being the ‘wrong type of person.’

Since White Privilege is Power, those with this Power need to use it to aid those who do not have it.  When you see someone being targeted simply because that person is not white, intervene. Use your Power to make your community a more welcoming place.
