Vitamin D Protects You From Flu, Oxford Scientists Find
Getting enough vitamin D really can help to protect you against the flu, a study by Oxford scientists has found, with people with severe vitamin D deficiency 33% more likely to be admitted to hospital. The Telegraph has more.
The study revealed that people with a severe vitamin D deficiency were 33% more likely to be admitted to hospital with a respiratory tract infection than those who were receiving adequate amounts.
Vitamin D is the only supplement recommended by the NHS for everyone during winter months, when exposure to sunlight, which the body uses to produce the nutrient, is limited.
It is already known to help regulate the amount of calcium and phosphate in the body, which is vital for bone and muscle health, but experts also believe it may have antiviral properties.
To test this theory, researchers from the Universities of Surrey, Oxford and Reading analysed data on 36,000 British adults to find out how levels of vitamin D in the body affected the rate of hospital admission with respiratory infections.
These included a range of viral and bacterial illnesses such as flu, pneumonia and bronchitis. Previous studies have linked vitamin D deficiency to increased risk of severe Covid, another respiratory infection.
The results from this latest study – the largest to date – revealed that people with a severe vitamin D deficiency, classed as having a concentration below 15 nanomoles per litre (nmol/L) in the blood, were 33% more likely to be admitted to hospital for respiratory infections than those with optimal levels of more than 75nmol/L.
The experts found that for each 10 nmol/L increase in vitamin D, the hospital admission rate for respiratory tract infections fell by 4%.
Overall, some 2,255 patients were admitted to hospital with a respiratory infection out of the 27,872 people included in the final analysis.

What a surprise. Incidentally, the recommended value by the NHS is a bit on the low side. Taking into account of what’s in the diet, I now use at least 100 µg vitamin D3 per day. Some suggest even more, if you look up this topic.
Yes I take at least that, and get a LOT of sunshine, winter and summer.
That is blatant misinformation.
Hancock assured Parliament there was no evidence whatsoever that Vitamin D helped any ILI’s and that the only way to salvation from the novel and deadly Covid lay in vaccination.
And being Health Secretary he should know.
A Health Secretary with no medical or health experience at all.
In fact, as far as I recall, NO Health Secretary has EVER had a medical qualification. Having a Secretary with actual practical experience in such an arcane and important field would be the height of political incompetence. They would inevitably challenge the advice of their supposedly expert (but politically alligned) Expert Advisers.
Wasn’t he an estate agent? Says it all.
No that is Trump’s son-in-law😂😂😂😂
Vit D is important for an effective immune system. It is an effective immune system that guards against infections by respiratory viruses and much else.
However if other aspects of diet, lifestyle, general health are weakening the immune system, eating Vit D by the bucket load won’t help much.
And a note of warning too much can be dangerous. My wife urgently had to stop badly affecting heart rate
You need to take D3 plus K2.
Since watching John Campbell’s analysis of high dose Vit D trials I upped my daily dose and combined it with 50mg zinc which was recommended. The NHS is way behind the curve on this. My specialist thinks I’m overdosing and keeps reminding me!.However, I haven’t had a cold or ILI since upping the dose which is a few years ago now.
If I remember correctly, the main concerns came from calcium uptake alongside, causing issues with the kidneys I believe (pinch of salt, been a while since I researched this)!
Seemed all the other concerns have largely been disproven by studies in various hospitals upping the dosage to 16,000iu or more! The body can produce upwards of 1000iu naturally, in 10-40 minutes conditions depending, which makes the recommended daily dose of 400 or so somewhat laughable!
We can produce large numbers of it, but I think it’s more or less a 3 stage process, with the first stage being in our skin, then onto the kidneys, and ultimately converted into vitamin D and stored in our liver. So the route via diet is a bit different compared with automatic generation. So the timing is different with one of the stages being missed out when we take it in that way.
I am another John Campbell fan, by the way.
Next they will be telling us that ivermectin is a wonder drug which GPs may prescribe at their discretion.
Another crazy conspiracy theory makes it to the MSM!
10 micrograms or 400 International units supplement per day is ridiculously low, at this latitude we should be taking 4000 – 5000 units a day.
My wife and I have been taking 10,000 iu a day for a long time.
How long before they withdraw this paper after pressure and threats..?
When I looked into this at the start of the Covid event I tried to work out when the 400 unit recommendation came in and why.
To the best of my knowledge it came in when the recommendation went from one tablespoonful of cod-liver oil to other dosage forms.
Now when I hear that a dose is the recommended dose I ask recommended for what?
At the time of the original dose recommendation, rickets was probably the only condition, related to vitamin D, there was any concern about.
Personally I take 4,000 units.
That number came up decades ago, as a result of various studies on the ‘rickets’ illness in malnourished kids. Also that resulted in the discovery of what became known as vitamin D. Related knowledge has increased since then, hopefully, but for ages they just stuck with the original number. However, it varies globally, if you look it up.
There are several diseases that are more prevalent in those with brown or black skin, hence with lower vitamin D levels generated by sunlight, so the benefits of vitamin D supplements may go far beyond flu.
The problem is that vitamin D cannot be patented, so no money in it for Big Pharma.
Amazingly it has the same effect for COVID but they cant say that for fear of educating the public. V axx manufacturers would be well out of pocket if the sheep know the truth. And most of them are so thoroughly conditioning that they would refuse to believe it.
Anyone paying attention to the sceptical side of the Covid propaganda knew this several years ago.
Well, hush my mouth and call me Shirley!
Have the “brilliant “ academics at Oxford only just realised this?
or, and this is more likely if they are really brilliant, they knew all the time, but couldn’t say or no one would have had the poison under the name of a vaccine pumped into them.
i wonder why this is being released now?
Most none exulted people have known the benefit of vitamin D since childhood.
The recommended dosage in this article is far to low.
Exactly. Best comment so far! 100%
Good of Oxford scientists to acknowledge the importance of vitamin D in preventing flu. In 2020 those with a negligible Vit D level were known to do worse when hospitalised with covid. That was five yrs ago. The word went out to take Vit D with K. Dr. Zev Zelenko prescribed Quercetin, Zinc, Vit C and D to keep covid at bay. That was five yrs ago.
Well blow me down…….!!!!!!!
