Vitamin D Supplements, Cancer Risk, Low Vitamin D-Dr Greger


Vitamin D despite the name is actually a a
pro-hormone and has many important multiple roles in the body from Maintaining the health
of our bones and teeth to Supporting the health of our immune system, brain, and nervous system.
Regulating insulin levels, Supporting lung function and cardiovascular health and influencing
the expression of genes involved in cancer development. This astonishing study found
that women with blood concentrations of vitamin D higher than 40ng/ml, had a 67% lower risk
of cancer compared women with levels lower than 20ng/ml. The researchers concluded that
optimal levels for cancer prevention are between 40 and 60ng/ml, which is 100-150 nmol/L) and
that most cancers occur in people with vitamin D blood levels between 10 and 40ng/ml. When
the esteemed cancer & health researcher Chris Wark was asked which supplement was the most
important for anti- cancer supplement listen to what his answer was….[Chris Wark] The
most important anti cancer supplement by far is vitamin D without a doubt no question.
Vitamin D, you want to get your blood levels between 40-60 ng/ml. There’s a website called
D action, grass roots D action you can order a vitamin D test for about $50 and see where
your blood levels are at because if you’re under 30 you’re in the risk zone for disease.
If you’re under 20 you’re in the really high risk zone. Supplementing with vitamin
D is essential because most of us don’t get enough sunshine and it’s really hard
to get enough sunshine daily to produce optimal levels of vitamin D in your body. [PBSL] So
does Dr Michael Greger’s research support this claim? And if so how much should we be
taking? [Dr Greger] Higher vitamin D levels are associated with improved survival in colorectal
cancer, and in breast cancer. In fact, about double the risk of breast cancer recurrence
and death in women with the lowest vitamin D levels. And, vitamin D levels also associated
with longer survival with ovarian cancer, and other cancers, like lymphoma. But, bottom-line,
is that you have to put it to the test. We now have a few randomized controlled trials,
and vitamin D supplements do indeed appear to reduce the risk of dying from cancer. What
dose? The researchers suggest maybe getting blood levels up to at least around 75 nanomoles
per liter; levels not reached by as many as three-quarters of women with breast cancer,
or a striking 97% of colon cancer patients. Getting up to these kinds of levels, 75, or
perhaps even better, 100, might require about 2,000 to 4,000 international units of vitamin
D a day—levels of intake for which there appear to be no credible evidence of harm
the findings of these kinds of studies may have a profound influence on future cancer
treatment. [PBSL] Recently I learnt that some people cannot efficiently absorb vitamin D
from supplements and this is concerning, because of the potential connection between vitamin
D & cancers . And the fact that most of us are not getting enough direct sunlight especially
if we live in northern climates. Is there a simple quick and effective way to help enhance
our vitamin D absorption from supplements? Well Lets’ here as Dr Greger tells us more
all the original links are in the description below. [Dr Greger] What do you do if you’re
one of the 42% of Americans with vitamin D deficiency, are put on a vitamin D supplement
regimen, and your levels still don’t budge? That kept happening to this group of docs
at the Cleveland Clinic. “In our practice,” they wrote, “it is common to see patients
treated with vitamin D supplements who do not achieve an appreciable rise in their [vitamin
D] level after therapy despite large prescribed doses.” So, they did a few experiments,
and concluded that “[t]aking vitamin D with the largest meal improves absorption and results
in higher [blood] levels of [vitamin D].” Just that one simple change in timing “results
in about a 50% increase in [blood] levels of [vitamin D] achieved.” They conclude:
“It therefore seems reasonable to ask patients to take vitamin D supplements with their largest
meal because it may be a cost-effective strategy that could very well help patients to achieve
optimal serum levels of [vitamin D].”

  1. Yeah had a profound effect on the dead doctors who used GcMAF to cure cancer etc. It's link for countering nagalase which is produced in cancer patients and how the vit D binding protein plays a role. David Noakes and others need your help. Here is a link to a PDF showing a diagram of how it works

  2. can someone tell me what the nano-whatevers equal to in hours stayed under the sun? we have more than enough sun here now in Lebanon but I don't want to get too little (or too much).
    Also, what are the best supplements for it?

  3. Michael Gregor forgot to mention that the reason why vitamin D is better absorbed with a meal is because it's fat soluble. Vegans should eat some nuts with their meal, otherwise there would be no benefit.

  4. According to this new study vitamin D does not lower our cancer risk.

  8. Is anyone up on Pam Popper's view of vitamin D? Pam Popper is usually on point, but I thought she said not to supplement D3. I'm definitely a bit confused on whether D3 supplementation is good or not….

  9. This year in January the largest and longest study on Vitamin D, with over 5 years duration and more than 25,000 people, came out and found no positive benefits from vitamin D supplements:
    https://www.nejm.org/doi/full/10.1056/NEJMoa1809944
    Now it has also been shown that the main promoter and researcher on vitamin D, author of “The Vitamin D Solution” took money from the supplement industry for decades:

  10. But excessive intake of vitamin D (as with any other nutrient) IS equally harmful!! We're better off getting our vitamins and minerals levels checked BEFORE supplementing. Btw, why is something as basic as that not done by doctors routinely?!? 🙄🤔🤔

  11. I don't steep foot outside without sunscreen so I do have to supplement. And now I know I should take it with a large meal. Thanks.

  12. A few days ago I saw a video on Pamela Poppers channel that vitamin D supplements are not good or something like that. So tired of hearing different things because idk what to do. I have a deficiency from time to time because I'm inside a lot and live in northern Europe so yeah… I also wear SPF when I'm out.

  13. Chris Wark , an esteemed researcher??? Isn't this an exaggerated description for an author who reads and summarises other people's studies?

  14. I read if you take too much vitamin d3. Your calicum goes up to protect the body which lowers vitamin d3.
    My ex was take d3 and he died stage 4 cancer in jan 2019.

  15. But but , skin cancer causes 💀 from the SUN but but, you need sun screen … 💀💀💀. So many people misinformed
