Could Vitamin D Help Fight COVID-19?

My opinion is that you keep the correct levels of vitamin D in your body. Now a days, due to staying indoors, it is possible that you will develop the deficiency of vitamin D. Get this checked by your doctor and use the correct dose to stay healthy.

Here are my notes:
Daily 10 microgram or 400 IU/Day

Lippincott’s Biochemistry Review 4th Edition. Page 388
Daily 5 mg of cholecalciferol or 200 IU of Vitamin D.

However, 800 IU/Day is shown to reduce the incidence of osteoporotic fractures.
800 IU/Day recommended by the Institute of Medicine to maintain bone health.

Frank deficiency is when the levels of 25-hydroxycholecalciferol (25OHD) is less than 20 ng/mL (50 mmol/L)

No consensus that the oral vitamin D supplements are helpful

Ergocalciferol from plants is called Vitamin D2
Cholecalciferol from the animal tissue is called Vitamin D3

7 deidro-cholesterol to (UV light) to cholecalciferol (D3) to 25 hydroxylase in liver to 25 OH D to -hydroxycholecalciferol 1-hydroxylase in kidney to 1,25 DiOH D3

Vitamin D Receptors are abbreviated to VDR in the notes. These are cytosolic receptors.

Deficiency of vitamin D makes people more susceptible to respiratory tract infections.
Vitamin D supplement can reduce these infections by 12%
Keep in mind, this is for those who are deficient in this vitamin. If you are not deficient, then it will not make a difference. Because, you are already good.
Evidence is not sufficient to say that vitamin D helps prevent respiratory infections.

2018 Study

People with autoimmune diseases commonly have hypovitaminosis D

What are cathelicidins?

What are beta defensins?

2011 Study

Activation of TLR and PAMPs on macrophages increases the production of 1, alpha hydroxylase and the VDR. This in turn causes more production of cathelicidine and beta defensins 4.

Vitamin D also affects monocytes to reduce production of IL1, IL6, IL8, IL12, and TNF. Regulating the immune response.

Vitamin D acts on the dendritic cells to inhibit/reduce their differentiation and maturation. It reduces their MHCII expression, co-stimulatory molecules like CD40, CD80, CD86, decreased production of IL-12 etc.

2013 Study

Vitamin D improves immune system by helping produce cathelicidine and by helping modulate inflammatory cascade. Especially for the respiratory infections.
It also helps produce NFk-B (nuclear factor kappa light chain for activated B cells.)

Notes about the NFkB

Helps with cytokine production and cell survival.
NFk-B factor becomes active when T and B cell receptors become active. Its activation causes the gene expressions that allow T cell development, maturation, and proliferation.
T and B cells have Vitamin D receptors that help them produce NFk-B

Continuing the notes from the study:
In pulmonary infections. Lung epithelial cells are able to convert inactive vitamin D to its active form. This active Vitamin D then helps produce cathelicidine. Which helps kill the pathogens.

Vitamin D seems to favor TH2 and TH17 cell activation which is anti-inflammatory profile.
Vitamin D seems to reduce the activation of TH1 cells which are pro inflammatory by their IFN-gamma action.
A deficiency of vitamin D may dysregulate the inflammatory response of the body.

Vitamin B also increases the IkBa. This leads to inhibition of NFkB. This helps reduce the production of IL6 and IL8 by inhibiting the production of NFkB.

Vitamin D might just save you from getting Covid-19

There may be a cheap and effective way to help prevent getting infected with Covid-19 and fighting it if you’ve already been infected. Taha Meli Arvas explains, In Brief.

Vitamin C, Vitamin D and COVID - Prevention of COVID

Vitamin C, Vitamin D and COVID - Prevention of COVID

Does colder temperature make you more prone to getting a cold Or COVID?
Most health experts agree that people spend more time indoors and in close contact with other people when it’s cold, which likely increases germs spread.
Also, experts believe that our immune system may be more active when our body is warmer, as in during the summer months.

COVID Update Today by Doctor Mike Hansen (YouTube Video Playlist)

Back in 2007, there was this study…

- In this one particular study looking at the spread of the influenza virus, they put guinea pigs together in a chamber and carried out different environmental experiments on them. They found that low relative humidities of 20%–35% were most favorable for infection, while the transmission was completely blocked at high humidity of 80%.
They also found that when guinea pigs were kept at 5 °C, transmission occurred with greater frequency than at 20 °C, while at 30 °C, no transmission was detected.
The authors concluded that low relative humidities produced by indoor heating and cold
temperatures favored the spread of the influenza virus.

I also want to add that cold weather, by itself, can cause a runny nose without necessarily
having a cold allows for the virus to be carried in those secretions, which probably facilitates transmission.
40% of common colds are caused by rhinoviruses. The second most common cause of cold is the coronavirus, the normal one, not this novel coronavirus.
Its been shown that the rhinovirus reproduces more quickly at cooler temperatures means you might catch a cold more quickly if you’re chilly.

And this probably applies to the coronavirus as well.

It's likely that with the combination of all of these 5 factors, meaning cooler temp, lower humidity, people staying indoors more often in winter months, cold weather causing runny noses, and our immune system is more active when it's warmer, these combinations of factors likely explain why colds, flu, and COVID are more likely to cause infections in the winter months.
But there is likely a 6th factor as well. And that is vitamin D. Our bodies don’t normally make vitamin D unless we get sunlight. In the winter months, for most of us in this world, we don’t get enough sunlight to make enough vitamin D. Unless you live in a warm, maybe you are the exception. So if you aren’t getting enough sunlight in the winter months, that means you have to get enough vitamin D in your diet. And if you don’t do that, you will have low vitamin D levels. Vitamin D helps regulate or Calcium levels and is important for bone and muscle health. It also plays a role in regulating our immune system, but its exact role is not known.

Why is this important for the common cold, flu, and perhaps with this novel, the coronavirus that’s causing COVID? Well, vitamin D doesn’t affect these viruses themselves. Instead, it affects our immune systems.

So what is my recommendation for taking Vitamin D?
The best thing to do is check with your doctor to see if you might have low vitamin D, and if it is low, you’ll def need to get more vitamin D, especially during the winter months.

Vitamin C is a water-soluble vitamin. It is vital to white blood cells that help to fight infections and overall immune system health. Vitamin C is also important for iron absorption, and being deficient in iron can make you more vulnerable to infections in general.
The normal, recommended daily intake of vitamin C for adults from the diet and/or supplements is 75 to 120 mg. You can get about 80 to 90 mg from a cup of orange juice or sliced orange, or even more from kiwi fruit or a cup of sweet peppers.

Zinc has become one of the most popular suggestions for reducing symptoms of COVID.
Some studies showed that zinc reduces the duration of a cold by half, while others showed no effect. Another study found that the type of zinc taken determined the result—zinc gluconate lozenges that provided 13.3 milligrams (mg) of zinc lessened the duration of colds, but zinc acetate lozenges that provided 5 mg or 11.5 mg of zinc did not.

Hopefully, YT does not take this video down, as it's all based on medical studies. If they keep doing this, I will have to upload my videos to a different website.

The Vitamin D supplement that I take:

Mentioned Video:
Vitamin D3 (Cholecalciferol) and Vitamin D2 (Ergocalciferol) and Calcitriol
Video Link:

So what does not having enough vitamin D have to do with COVID 19? And IF insufficient vitamin D levels CAUSE more severe disease, why is that? Well, I have to first clarify that it's not proven that insufficient vitamin D levels lead to worse outcomes. But while it hasn’t been proven, it also certainly hasn’t been disproven. And there is more and more compelling evidence suggesting that lower levels lead to worse outcomes. And there’s no question that vitamin D plays an important role in our immune system. More and more studies are coming out that are sorting out its exact role in this capacity. But the link between poor vitamin D status and risk of certain infections remains cloudy. In 2017, a meta-analysis study consisted of 25 different randomized trials with about 11,000 patients in total, evaluating the incidence of acute respiratory infection.

Vitamin D supplementation reduced the percentage of patients experiencing an acute respiratory tract infection. The incidence of URTI in the vitamin D group was 40.3%, compared to 42.2% in the placebo group. In a subgroup analysis, vitamin D supplementation was most effective in patients with vitamin D levels less than 10 ng/mL and those treated daily or weekly smaller doses instead of a huge single dose. The takeaway from this meta-analysis study is that being vitamin d deficient probably makes people more prone to getting upper respiratory infections and should take supplemental vitamin D. But people who have low levels should be taking supplemental vitamin D regardless. Vitamin D has major effects on nearly all our immune system cells, including dendritic cells, macrophages, and T and B lymphocytes. These immune cells have a receptor that binds to vitamin D, called the vitamin D receptor, or VDR.

Here are some questions we still need answers to:
1) what level of vitamin D is adequate to protect against or minimize the impact of COVID 19?
2) What level of vitamin D is considered too high
3) should more and more people get their vitamin D levels checked, especially during this pandemic, when fewer and fewer people are physically going to the doctor?
4) should people just supplement themselves? If so, how much?

These are all tough questions to answer, especially because we won’t have RCT results for vitamin D anytime soon. Given that low dose, vitamin D is pretty darn safe, it seems quite reasonable for people to take a low dose supplement, especially if they think they might not be getting enough from sunlight or their diet. Of course, ideally, you want to have a discussion with your doctor if possible.

A common question is, How much Vitamin D should I take a day?
Personally, I take 1,000 IU per day. I know that I’m not going to run anywhere near toxic levels of vitamin D with that dose, while at the same time, I know that I won’t be vitamin D deficient.
