US

42% of people have a vitamin D deficiency

82.1% of black people

69.2% of Hispanic people.
Higher blood levels = over 33 ng/ml or 82.4 nmol/l
Lower blood levels less than 12 ng/ml or 30 nmol/l
50% lower risk of colorectal cancer
Consuming 1,000 IU (25 mcg) daily would help 50% of people reach a vitamin D blood level of 33 ng/ml (82.4 nmol/l)
Consuming 2,000 IU (50 mcg) daily would help nearly everyone reach a blood level of 33 ng/ml (82.4 nmol/l)
Taking 1,000 IU (25 mcg) of vitamin D daily reduced heart disease risk by 10%
Consuming 1,000–4,000 IU (25–100 mcg) of vitamin D daily should be ideal for most people to reach healthy vitamin D blood levels.
However, don’t consume more than 4,000 IU of vitamin D without your doctor's permission. It exceeds the safe upper limits of intake and is not linked to more health benefits

Dr. John, you have changed my life. As a black person living in the UK, you have enlightened me. I now take Vitamin D supplements religiously and I feel so confident with my health moving forward. May God bless you.

Hair loss and thinning is my problem, and menopause depression. I started watching you during Covid and learned about the importance of Vit. D. Thank you!
I take 5, 000 in daily. Since starting that dose, my hair is not falling out by the handful and, it’s finally growing longer. It really made a huge difference! I also had Covid 19 twice and had moderate cold symptoms and loss of taste and smell for only 2 days. I have you, Dr. Campbell, to thank for my better health. Next pestilence coming sooner than later and I’ll be right here, learning from you!! 🙏🌺🐝

There is also a relationship between low vitamin D during the winter and depression. I just retired as a mental health therapist and D has been helpful to me with mood stress. The counseling clients I worked with who were willing to take 2, 000-4, 000 IU had far less problems with depression and many were actually able to get off anti-depressants. Good sleep patterns are also essential to mood stability and -- I believe -- stronger immunity.

Thank you for this video!

Vitamin D
How many vitamin D should I take?

It depends on several preconditions.
1: your actual status of vitamin D
2: your body weight
3: your behavior and your skin type

1: If your actual status is to low and you start to take your dailymaintenance dose, it will take months or years until you reach a sufficient level.

2: how much you take it’s directly dependent from your bodyweight.
For example: 100 kg male needs the double daily maintenance dose then a 50 kg woman.
Due to the newest studies the level of vitamin D can be much higher than it was recommended before. (Michael F. Holick, USA)(80 ng/ml)

As a rule of thumb you are good if your daily vitamin D intake is between 70 and 90 iU per kilogram- after you have compensated your deficiency.
So for the hundred kilo man it’s between 7000 and 9000 IU/day. Daily intake is better than weekly, specially due to the immune system.
It is not possible to overdose with this amount.
A theoretical toxicity of vitamin D is a relative vitamin K2 deficiency. Therefore you have to take really high doses vitamin D over a long time.
(This is like trying to pump up a lorry tyre with a bicycle pump and being afraid of bursting it.)
Also the heavier ones need more in the beginning to compensate the deficit.

3: normally you get vitamin D from the sun.
But this works in our part of the world only between 15th of March and 15th of September.
It is in inevitable that’s the sun is standing higher than 45° cause your skin needs UVB rays to produce vitamin D.
Also the sky must be clear, -blue sky.
The skin surface should be as great as possible- uncreamed.
Suncream inhibits vitamin D production.
The time depending on your skin type it’s only between 10 or 20 minutes each side. After this time your skin will not produce more vitamin D.
In this case the skin can produce about 20, 000 iU per day.
A high vitamin D level protect from sunburn. Studies have shown that higher vitamin D levels are protecting from all sorts of cancer. Some are reduced more than 90%.
Sorry my English isn’t perfect but it should do.

My wonderful physician is especially vigilant with her patients' vitamin levels, therefore, I was instructed to supplement both D and B12 some years ago. In these troubled times I am fortunate to have received such excellent care.

[paxetbonum]

I worked in a medical lab setting. We performed about 150 Vit D level assays per day. Of that number we found approximately 60% of the patients with Vitamin D level below 20 ug.I often commented about this finding between my coworkers.

[patriciamasterson]

Thank you once again from Saint Helena CA. USA. Am 78 yrs and have chronic Lyme Disease. Am taking 5000 I either K2.

Paramedic here, been working the front lines, taking tons of flights during COVID and testing people for COVID-19. Havent gotten sick, there was a moment for about 2 days I felt like my chest might be getting heavy. Since the begining ive been taking Vit D like... a massive amount at least 10, 000 UI a day in the start - then now every other day or so, along with Calcium, Vit C, and Echanacea. Also, on this topic I do have caramilk skin and a mix of Austrian and Jamaican heritage - meaning that also my skin color in some way plays a role in my vit D levels. So far I havent gotten noticeably sick other than the chest tightness, ive been on the front lines since day one, quaruntined a few sick people. So I would recommend w.e. it is that Vit D c/ Calcium and Vit C does. Im not recommending it as a treatment as a paramedic, im recommending it as a friend of humans, seems to have worked well for me. ALSO, I am Type O blood and apparently there is some data stating that we do see reduced symptoms in that blood type as well. Food for thought. Stay safe and PLEASE call when you need us, Where ever, When ever - Well be there for you.

Thank you for your videos. I share them with everyone I know. I'm African American. I was well into my 40s before a primary care physician recommended that I get my vitamin D levels tested and to take supplements. This really needs to be part of the public health messaging in the U.S..

[gjt]

I would just like to thank you John, I’ve been taking 2000 IU’s of vitamin D3 and 100mcg of vitamin K2 for the last 3 weeks after watching your channel. My hay fever has disappeared and a big patch of Eczema on my elbow is healing, it all makes sense because I work night shifts and my skin has cleared up before on holiday in a sunnier climate. No more harmful steroid sprays and creams.

[barbaraduffell]

Thanks Dr. John from Oklahoma! I have been taking Vitamin D 5, 000 IU for many years per my Immunologist. Have blood test every 6 months! Enjoy your informative videos!🌞💕

[melaniedeatrich]

Doctor, thanks to you I began taking Vitamin D supplements months ago when I first heard you talk about that huge meta-analysis study. It seemed to me that if I'm deficient I need to supplement whether or not it will protect me from COVID-19. I'm sick that medical professionals in leadership positions around the world didn't make recommendations for supplementation months ago and I wonder how many people could have been saved. Thanks to you from me and my family.

[rahn]

I've been personally taking 2000 UI a day (recently upped to 3000 UI) in response to the growing evidence that low levels of vitamin D resulted in more severe cases of the disease.
An unexpected side-effect that I wasn't considering was that it seems to have been improving my mood. I suspect that I was vitamin D deficient, something it seems my doctor hadn't really considered when attempting to treat my depressive episodes.

[andrei]

I live in Moscow. After my tour to Thailand, I noticed a significant improvement in my health because there is a lot of sun and vitamin D. Then I started taking 5000 IU a day to keep my D around 60. It is improving my mood. I rarely get the flu now.

[GarryBurgess]

Half way through the video I've doubled my dose. Thank you very much for such helpful information, and greetings from Canada.

[theonlylionesse]

Thank you Dr. Campbell from Brooklyn. My pcp, 6yrs ago noticed I was low in Vitamin D and prescribed a Vitamin D regimen for me. He also advised that people exactly what you stated, people of African descent tend to suffer from low vitamin D. Hopefully NY's medical professionals and officials will realize this as a possible valid reason for disparity in COVID-19 infections and death rates.

[brendamartin]

I have taken 5000 IU for several years for my bones. At 70 they are no longer borderline osteoporous. Very happy that is also helping my immune system.

[islandbirdw]

I am a fellow RN in USA and I live in the NW northern hemisphere. I’ve been taking vitamin D year round but I titrate the dose up in October-November and titrate back down in March-April. The doses I use are 2-3000 IU, then up to a max of 5000 IU in dead of winter. I’ve had serum vitamin D levels measured at my peak dose and surprisingly it was in the recommended range but not even close to the highest level allowed. So I could even take more and still not be too much at least for my body chemistry and the climate of the extreme northern hemisphere.
I have definitely noted better resistance to catching colds and flu. So far I haven’t contracted CoV19 but I live in a more rural part of my community with fewer cases for now. Despite this I’ve been masking in public now since January when I saw leaked utube videos from China. My expertise is in critical care, cardiology and cardiopulmonary rehab nurse specialist for 33 years I just could tell how very dangerous virus was.

I myself have weak lungs. From a very young age I had croup every time I got a cold or flu. I’ve had 6 bouts of pneumonia that resulted in a gas enhanced pulmonary function testing that showed I have a diffusion abnormalities that impair gas exchange. Not taking any chances.

[WeOutHere]

Heard Joe Rogan takes 4000 IU so I upped mine to 6000 IU in case I have to fight him.

[heatherb]

My doctors have always told me I had low vitamin D, ever since watching you I’ve started taking supplements for vitamin D. It’s good information to know for sure! Rather be safe then sorry. Thank you Dr!
