Vitamin D reduced the rate of ICU admission from 50% to 2%. Do black lives matter?

Given that people with dark skin are more likely to be deficient in Vitamin D, wouldn’t studies like these be the best way to show that black lives actually matter? Would you like training in cultural sensitivity or to avoid the intensive care unit?

A free antiviral shining down on you?

In the Castillo study in Spain, 76 patients were randomly assorted into Calciferol treatment ( 0.532 mg Vitamin D ). Of the 26 who didn’t get it, 13 were admitted to the ICU. Of the 50 who got Vitamin D doses on days 1, 3, and 7 — only one ended up in the ICU. It’s worth noting that all patients got HCQ as well, and azithromycin too.

A second study tested 500 people to find out if they were deficient and followed them to see if they caught Covid.

Why has it taken 6 months of pandemic to do these small studies?

Before the pandemic came there was already ample evidence suggesting that it mattered. Vitamin D influences over 200 genes. Its levels also correlate with lower rates of cancer, diabetes, high blood pressure, asthma, heart disease, dental caries, preeclampsia, autoimmune disease, depression, anxiety, and sleep disorders.

Wow. Vitamin D deficiency may cause 40% of respiratory deaths in older people

It’s really quite a scandal.

Missing out on the Sunshine Vitamin?

Historians will marvel that societies that were advanced enough to stream reality-tv-shows at 100 million bits per second, were also so backwards that half the population was deficient in Vitamin D — something that costs 6 cents a dose or comes free from the sun. Nearly 60% of older Germans were deficient, and the ESTHER study puts a fine point on how much that matters. Almost 10,000 people were followed for 15 years in Germany, and during that time about half the people who died of respiratory illnesses might not have died if they had enough Vitamin D.

In this German study 44% did not have adequate Vitamin D and about 1 in 6 people have levels so low they are clinically deficient.

Imagine if someone found a drug that stopped nearly half of all influenza deaths?

Right now, the Northern Hemisphere has higher levels of Vitamin D than most months which is quite likely reducing the death rates. The message needs to get out about Vitamin D before the next Northern Winter.

 

Morethan half the population is deficient.

In terms of respiratory diseases, those whose [...]

Indonesian study: Low Vitamin D patients ten times more likely to die of Coronavirus

Wow. If this is confirmed, Coronavirus is almost a disease of Vitamin D deficiency

Missing out on the Sunshine Vitamin?

Hot off the press: A new Indonesian study of 780 people with Coronavirus found that people with a Vitamin D deficiency were much more likely to die. We discussed Vitamin D at length a few weeks ago, so we already knew Vitamin D is associated with a lower rate of respiratory illness, but the results here are quite remarkable.

Of those who died most (85%) had a co-morbidity, the real surprise is that even more than that, 96% had low Vitamin D levels. Of those who survived, most people had normal Vitamin D levels. Only 7% of survivors had low or deficient Vitamin D. That is quite a split.

Vitamin D deficiency was very common among these Indonensian patients. Half of those measured did not have enough Vitamin D in their blood. Of those that did, 96% survived, and only 4% “expired”. Vitamin D looks like a good protector.

After controlling for known risk like being old, or male or having high blood pressure, a Vitamin D level described as deficient (less than 20ng/ml) was associated with a 10 [...]

Perhaps solve the other pandemic: Vitamin D deficiency — to help beat Coronavirus?

Missing out on the Sunshine Vitamin?

We’re throwing billions at Coronavirus but missing cheap wins.

After masks and soap, the next bargain to reduce the impact of coronavirus is Vitamin D supplements.

Vitamin D deficiency is so common it’s an epidemic affecting a billion people around the world. Ponder that half the population of many western nations are clinically deficient by the end of winter. Add that to a novel virus and consider that higher Vitamin D levels reduce the risk of respiratory tract infections like influenza by as much as 40%.

As Grant et al say:

“Low vitamin D status in winter permits viral epidemics.”

Vitamin D levels also correlate with lower rates of cancer, diabetes, high blood pressure, asthma, heart disease, dental caries, preeclampsia, autoimmune disease, depression, anxiety, and sleep disorders. Vitamin D influences over 200 genes. It’s so crucial, it was likely the reason northern Europeans evolved whiter skin. The lack of sunlight and the introduction of grains in diets (as opposed to eating liver and whales) meant that Europeans weren’t getting enough D from either food or sun. The selective pressure was so strong that lighter skin rapidly took over all the northern [...]
