I so disagree, my D level was in the tank when I woke up to this issue in late 2006….I was bordering on depression and I live in Sunny calif….but came in from years of being in the sun mostly due to cancer scares……plus I could not tolerate the sun like I did as a younger person….I’m 76.
I live in Minnesota & I’m in my 40’s & mine is below 4. I disagree. I have pain all over, depression like I’ve never had and THIS should be mandatory in my opinion.
lack of exercise contribute to higher rates of cancer and heart disease, so those factors could explain the illnesses, rather than a low vitamin D level. thank you for this information.
This article is very interesting. I am always with low levels of vitamin D. I also have dark skin so is more difficult for me to absorb sun rays to form vitamin D.
Very much informative article. It is well known the relation between calcium , viteman D3 & osteopirosis. But I learned many new things from this article. I want to know the relation between vit D3 defficiency & control if Dia.
Vitamin D we can get in early morning sunrays

Vitamin D is the beneficial for human body. Thank for sharing this post.
Vitamin D is utilized for counteracting and treating rickets, an illness that is brought about by not having enough vitamin D (vitamin D lack). Vitamin D is likewise utilized for treating powerless bones (osteoporosis), bone torment (osteomalacia), bone misfortune in individuals with a condition called hyperparathyroidism, and an inherited malady (osteogenesis imperfecta) in which the bones are particularly weak and effortlessly broken. It is additionally utilized for forestalling falls and breaks in individuals at danger for osteoporosis, and counteracting low calcium and bone misfortune (renal osteodystrophy) in individuals with kidney disappointment.
Thank you for the research about vitamin D.It is highly
useful for all.
Excuse me, I come from Indonesia. Good article above, and add to my knowledge, once again thank you very much.
First when the same group found scant evidence to support routine PSA test or other cancer screening test the medical community particularly the groups benefiting the most $$$ went screaming and hollering about how many lives would be lost. The comment “The safe upper limit is 4,000 IU a day, but keep in mind that there’s very limited research on the long-term safety of taking that amount. “When it comes to vitamins, more is not necessarily better,” Dr. Manson says.”… and yet largely because of the medical community sun exposure has been demonized to the point many are in fact far less than optimal….perhaps Dr. Manson should have noted that that policy has never been evaluated as to long term effects.The most reasonably position seems to be expressed here …. “Why the IOM recommendations for vitamin D are deficient.
Heaney RP1, Holick MF.
The IOM recommendations for vitamin D fail in a major way on logic, on science, and on effective public health guidance. Moreover, by failing to use a physiological referent, the IOM approach constitutes precisely the wrong model for development of nutritional policy.
The fact is most studies on vitamin d use only small amouts often the wrong type D2 instead of D3.

A study done in 2011 Wiley-Blackwell. “Vitamin D can help elderly women survive, review suggests.” ScienceDaily. ScienceDaily, 6 July 2011. . noted The eight-strong international team of researchers identified 50 randomised trials that together had 94,148 participants. They had a mean age of 74 years, and 79% were women. “Our analyses suggest that vitamin D3 reduces mortality by about 6%. This means that you need to give about 200 people vitamin D3 for around two years to save one additional life,” says Bjelakovic.
There were no significant benefits of taking other forms of vitamin D……”
One MUST get it from both sources….food and sun to absorb calcium. Soooo why isn’t it required in nursing homes to get lamp or outside exposure? Also, even the experts talk about one source w/o mentioning the other….if the goal is to absorb calcium then both sources must be used.
Get tested, why wouldn’t you want to know if you are deficient? My level was 22 after years of taking the rmd of “D”. I also had osteoporosis and very low bone density. I raised my “D” to the mid 30s by taking 3,000 iu for years and over 8 years gained 35% in my spine and 23% in my hip. Pay no attention of expert advice unless you want untreated osteoporosis.
I have no idea why the experts are so intent on keeping people uninformed and possibly “D” deficient.
You said “I have no idea why the experts are so intent on keeping people uninformed and possibly “D” deficient.” Reason number one,
Cognitive Dissonance runs rampant in the health care professions. Number two, health care professions stand to loose billions of dollars of annual revenue if the vitamin D deficiency is corrected.
EDITOR: Some mushrooms are now irradiated, but most are not, and so will not contain vitamin D (label will state).
Vitamin D is operates as a ‘hormone’ that affects immune system regulation and functioning. In our modern society, many factors contribute to the likeihood that we do not have enough vitamin D: we do not go outside, sunblock, shirts, too hot , etc (all of these inhibit vitamin D levels). WHY not have vitamin D levels checked for patients with HEADACHES, FATIGUE, JOINT PAIN, Arthritis, Allergies, Eczema, etc (these are all influenced by imunne system functioning). In my practice, patients that have had low vitamin D often have other nutritional issues as well, inclduing low iron, B12 deficiency, etc. It may be more benficial to have nutrient deficiencies evaluated versus multiple prescription medications to address just the symptoms, and not the underlying cause(s).
I can’t wait for the results of the VITamin D and OmegA-3 TriaL (VITAL). I’ve been taking Omega-3 consistently for the past 14 years after I’ve had a quintuple bypass surgery at a young age. I also taken vitamin D off and on, after a blood test indicated that my vitamin D levels were low. I stopped taking vitamin D after reading mixed reviews.
very intereresting, thank you for this nice article. We will speak about it in our blog.
I think vitamin d us an important factor at human’s body so we can get it from sunrays
