Does Vitamin D help with Immunity? | Vitamin D and Covid

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

Vitamin D3 (Cholecalciferol) and Vitamin D2 (Ergocalciferol) and Calcitriol

So what does not having enough vitamin D have to do with COVID? 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 insufficient vitamin D status and the risk of certain infections remains cloudy. For example, in 2017, a meta-analysis study consisted of 25 separate randomized trials with about 11,000 patients in total, evaluating the incidence of acute respiratory disease.

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 less than 10 ng/mL and those treated daily or weekly with 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?
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, mainly because we won’t have RCT results for vitamin D anytime soon. However, 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.

I am a doctor working in India, and I find your video and subjects interesting, contemporary, and refreshes and adds on to my knowledge. Kudos Doc, keep it up. Waiting list more topics.

[stikaeric]

There is a reason why the flu is worse in winter when we get less sun and so less Vitamin D. This is a very good video.

[stikaeric]

When you are critically ill it is too late. Better to get D levels up now.

[bluemoon-pmhv]

I take D3 with K2 and has helped me greatly with a lot of health issues, just saying about myself. Everyone should do their own research. God bless✌❤

[dsmj]

People need to start fighting back against YouTube censorship.

[jamesstevenson]

This doc sounds as if he knows what he’s talking about. Very educational . The information he shares just flows from him like water flowing from a tap.

[mduduzigama]

Ever since I found this channel a month and a half ago, my love for medicine has been given a turbo boost. Thank you

[redhedhik-chik]

One more comment; my last 4 years I worked in intense mental health. Those who were deficient consistently had poor self image, unexplained depression, and negativism. Those who agreed to supplementing with Vitamin D had startling recoveries! Ty again.

[scottgoodman]

I can't think of a rational reason to remove a video of a man discussing scientific studies. For God's sake, this is one of the good uses of technology.

[redhedhik-chik]

May I say this; after intense work in corrections (dark environments, poor diets, high stress) as a RN, I observed 'miraculous recoveries' in those who supplemented with Vitamin D! One patient was hospitalized several times with no diagnosis except Vit D deficiency: he had respiratory symptoms (cough, low O2, malaise). He was able to afford supplements and made a full recovery. However, he would occasionally relapse and neglect his Vit D supplements for long periods; his symptoms would reappear! This was not an isolated incident: I observed these symptoms in many of my correctional patients. Also, those with fair skin and in particular, those with blue, green, or hazel eyes were most likely to have these symptoms. Also, African American patients also experienced the same. Sometimes they would also have unresolved/unexplained deep leg pain that didn't respond to pain relievers or stretching. I literally observed hundreds of patients over a period of 12 years. Let me also add that those with type 2 diabetes almost always had Vitamin/mineral deficiencies: supplements and diet education is a neccessary part of their maintenance and recovery of symptoms. Ty for your advice and sry for the long comment.

I'm practicing primary care in Chicago and have been checking vitamin d levels with the routine yearly labs. Universal insufficiency/deficiency in everyone not taking supplements.

[c.g.ku.]

Being a Hashimoto patient, I take 10000 IU D3 and 200 mcg K2 daily in the months of November, December and January. In Germany, those are the dark months. The rest of the year, I'm fine with 5000 IU D3 and 200 mcg K2 daily. Stay safe and good health to you all!

[petuniaandpoppy]

Thanks for not dumbing it down. Keep up the high quality content. We really appreciate you taking the time to get this level of detailed info out to those who wouldn’t otherwise have access.

[LGFITNESS]

More doctors should care to educate us the way you do:

1. Without their prescription and hidden “selling points”; 🤥
2. Without us having to pay top dollar for unnecessary medical consultations; 🤑
3. Without putting our lives at risk by requiring unnecessary medical consultations during a global pandemic! 😷
4. Without expecting us to always know which and when to ask the “right questions”; 🤔
5. Without expecting us to know which Google link is the “bull’s eye” credible source; 🥵
6. Without expecting us to trust media and their politicized “contaminated” doctors! 😡
7. Before we’re on the verge of dying! 🤢🤮🤒🤕😑

I’ve learned so much from you in just a few of your videos!
Thanks SOOO very much!!!

[BT-kmnl]

Mike Hansen is my type of doctor, precise, strongly and strictly scientific, reference based, fluent in his videos. I am sure he is a star in the hospital. greetings from Sweden.

[BigHenFor]

I find it highly ironic that YouTube are policing educational content like this, but allowing quackery like Soulvana to plaster their ads all over your content Dr Hansen.

[ExecDefense]

Glad YT didn't take it down! We need this reliable information to help make informed decisions concerning health. Keep up the great work Dr. Mike.

[guygrotke]

Life guards in Hawaii have levels around 70 ng/ml, and they never have toxicity. 4000 iu/day will raise your level by about 40 ng/ml. That's a pretty decent level with no danger of toxicity, unless your doctor has told you otherwise.

[JohnHalbleib]

Thank you for this. I’ve followed your videos for about 5 weeks now and was especially interested to hear what you had to say about vitamin D and it’s potential relevance to the current pandemic. Great information.
