Y’all keep slathering on that sunscreen. Wouldn’t want you to get any of that pesky vitamin D.
Thanks for posting this.
I’ve seen that it was rare that people with good levels of Vit. D got Covid.
Ironically that sunscreen is what’s partially responsible for coral bleaching.
People slather it on, then go in the ocean and it washes off and blocks the sunlight portions corals need to survive..................
My rheumatologist has me on vitamin D for scleroderma. Scleroderma is a thickening of the skin that manifests like arthritis.
“People slather it on, then go in the ocean and it washes off and blocks the sunlight portions corals need to survive”
how many tera-tons of washed off sunblock are needed from U.S. beaches to reach and destroy coral reefs thousands of miles away?
It’s not just US, but everywhere all over the earth. It’s used by beach-goers everywhere...............
Oh, this is from Mercola. His net worth from selling “supplements” and useless “devices” is over $100 million. He sells this stuff by implying that he’s selling miracle cures. Nope, I have no desire to increase his net worth.
If vitamin D were really a cancer killer, how is it that people who get plenty of sunshine still get cancer?
Vitamin D is far more like a hormone than a vitamin. It also has a LOT of actions, both in its original form and its breakdown products.
However, a small number of people get a bad reaction to taking it in supplement form, and a different small group of people do not absorb it easily in that form.
And while you can absorb sunlight through your skin to produce it, it takes a long time, perhaps two weeks, before it turns into serum (blood) Vitamin D.
It helps modulate immune response to pathogens, both familiar and unusual. It prevents an overreaction by acting as an ACE inhibitor. One of its breakdown products is known to erode viral coats in the blood, killing the virus.
It also activates and opens up other immune pathways, making for a more effective response.
Excellent.
My sister has neurological problems - her vitamin D level tested as 0. She’s had to have infusions twice a day. Going out in the sun is not an option given her coloring and that she lives at 6,000 feet.
Recent blood test was 59ng/mL. I take 5000 IU vit. D /day plus magnesium and K2,
Me too!...................
Perhaps for more people would get cancer if they didnt take vit d. It certainly isn’t a cure all, but there seems to be mounting evidence that it can help- perhaps people with low d get cancer far more frequently than people with adequate d levels.
I drink a lot of whole milk, and go out in the sun without sunscreen, and I do not have cancer.
Just sayin....
There are several 10,000 IU d3 products hitting the market, as well.
I will say that Vitamin D is a wonder drug.
I have had patients with low Vitamin D who are depressed. After getting the levels up they felt oh so much better.
Thanks for posting about vitamin D.
For years I’ve heard about huge benefits from vit. D. Then I recently came across some cautioning info. I’m not a medical expert and am not sure what to make of this.
Bottom line: According to the following article from the NIH, “the evidence was inadequate or too contradictory to conclude that the vitamin [vitamin D] had any effect on a long list of potential health outcomes (e.g., on resistance to chronic diseases or functional measures), except for measures related to bone health.”
Here are selected quotes from the very long NIH article:
VITAMIN D
Colorectal cancer
... Vitamin D alone did not significantly affect the development of new serrated polyps, but the combination of vitamin D with calcium increased the risk almost fourfold. The VITAL trial found no association between vitamin D supplementation and the risk of colorectal adenomas or serrated polyps
Pancreatic cancer
An investigation that pooled data from 10 studies of cancer in 12,205 men and women found... an increased risk of pancreatic cancer with 25(OH)D levels of... 40 ng/mL or above
Prostate cancer
Research to date provides mixed evidence on whether levels of 25(OH)D are associated with the development of prostate cancer.
Several studies published in 2014 suggested that high levels of 25(OH)D might increase the risk of prostate cancer.
Breast cancer
Some observational studies support an inverse association between 25(OH)D levels and breast cancer risk and mortality, but others do not...
Conclusions about vitamin D and cancer
The USPSTF stated that, due to insufficient evidence, it was unable to assess the balance of benefits and harms of supplemental vitamin D to prevent cancer...
Taken together, studies to date do not indicate that vitamin D with or without calcium supplementation reduces the incidence of cancer, but adequate or higher 25(OH)D levels might reduce cancer mortality rates.
Further research is needed to determine whether vitamin D inadequacy increases cancer risk, whether greater exposure to the nutrient can prevent cancer, and whether some individuals could have an increased risk of cancer because of their vitamin D status over time.
Cardiovascular disease
... Overall, clinical trials show that vitamin D supplementation does not reduce CVD risk, even for people with low 25(OH)D status (below 20 nmol/L [12 ng/mL]) at baseline
Type 2 diabetes
... Clinical trials to date provide little evidence that vitamin D supplementation helps maintain glucose homeostasis, reduces the risk of progression from prediabetes to type 2 diabetes, or helps manage the disease, particularly in vitamin D-replete individuals.
Health Risks from Excessive Vitamin D
While acknowledging that signs and symptoms of toxicity are unlikely at daily intakes below... 10,000 IU, the FNB [Food and Nutrition Board] noted that even vitamin D intakes lower than the ULs [Tolerable Upper Intake Levels] might have adverse health effects over time.
The FNB recommended avoiding serum 25(OH)D levels above approximately 50–60 ng/mL, and it found that even lower serum levels (approximately... 30–48f ng/mL) are associated with increases in rates of all-cause mortality, risk of cancer at some sites (e.g., pancreas), risk of cardiovascular events, and number of falls and fractures among older adults.
[This link has much more info on all of the above:

Frankly, I’d much rather believe all the positive things that Mercola (and many others) say about vitamin D. But the above info from the NIH is troubling.
I don’t know how to reconcile the two.
Maybe someone who knows more than I do can comment.
Just wanted to add that I suspect that at least some of the negative findings regarding vitamin D (in my post above) might be due to the fact that many people who take vit. D supplements are also taking high doses of calcium, since the two are often combined.
So I wonder if maybe the excess calcium is causing some of the problems that the NIH overview attributes to vit. D.
But I really don’t know.
“ Ironically that sunscreen is what’s partially responsible for coral bleaching.”
Wow, I never considered that.
Several other factors also. It the Caribbean it’s also Sahara Desert dust from Africa that carries microorganisms that damage corals...........................
