Usually in cold weather the clouds are sparse and their blanket effect is not there, and we see the sun in th daytime. This winter the skies have been heavily sprayed blocking out sunlight. This cuts Vitamin D levels to the lowest levels. Here’s a few reasons why we need Vitamin D from Dr Mercola. Get some rays when you can.
Vitamin D Even Improves Pancreatic Cancer
Another little-talked-about benefit of vitamin D relates to pancreatic cancer, one of the deadliest forms of cancer with a five-year survival rate of just 7.2%.31 Researchers published the case of an 83-year-old woman with pancreatic cancer “who errantly took supratherapeutic doses of vitamin D 50,000 U daily, achieving a serum 25(OH)D level of more than 150 ng/mL, with no appreciable side effects.”
Eight months after diagnosis — and consistent daily intake of high-dose vitamin D — scans revealed “no evidence of disease progression.” Further, the researchers noted, “Currently she describes as feeling quite well with no difficulty accomplishing her activities of daily living.” They called for further research to investigate:32
“One cannot conclude that her vitamin D dose was in any way related to this outcome. There is only one CT scan before the initiation of vitamin D, and there is no way to know what her pace of disease would have been in the absence of vitamin D supplementation. In addition, she was taking several other supplements such as shitake mushrooms, although inconsistently and for a shorter duration, which were also intended to treat her malignancy.
Nonetheless, given the poor prognosis of pancreatic cancer and the limited treatment options for patients, this case should stimulate further investigation. The daily dose of 50,000 U of vitamin D3 was well tolerated in our patient for over 10 months at the time of writing. Consideration should be given to a clinical trial that evaluates a similar dose.”
I’ve long recommended a vitamin D level of 40 to 60 ng/ml for optimal health and disease prevention. However, higher levels of 60 to 80 ng/ml may be even better, while a level upward of 100 ng/mL appears safe and beneficial for certain conditions, especially cancer.33
Ideally, Get Your Vitamin D From the Sun
Optimizing your vitamin D levels isn’t only about preventing COVID-19; it supports health in multiple ways. It’s been shown that people genetically predisposed to vitamin D deficiency were 25% more likely to die from any cause compared to those with different genetics conducive to healthy vitamin D levels.34
To optimize your levels, regular sun exposure is the best option, as not only will it naturally raise your vitamin D levels to healthy levels, but it will provide numerous other benefits, such as enhanced production of melatonin — a potent anticancer agent.35 However, if you’re unable to get adequate sun exposure each day, supplementation may be necessary.
The only way to determine how much sun exposure is enough and/or how much vitamin D3 you need to take is to measure your vitamin D level, ideally twice a year. When supplementing, also remember vitamins D and K2, calcium and magnesium all work together and must be properly balanced for optimal health.
Once you’ve confirmed your vitamin D levels via testing, adjust your sun exposure and/or vitamin D3 supplementation accordingly. Then, remember to retest in three to four months to make sure you’ve reached your target level.
