BACKGROUND FROM DAN MURPHY | |
The world standard uses nmol/l, while US standard uses mg/dl. | |
For vitamin D, to convert mg/dl to nmol/l, divide the mg/dl by 2.5. | |
For vitamin D, to convert nmol/l to mg/dl, just multiply by 2.5. | |
KEY POINTS FROM THIS ARTICLE: |
|
1) “Over the past several years, the surprising prevalence of vitamin D deficiency has become broadly recognized.” | |
2) Vitamin D deficiency is linked to: Osteoporosis Cardiovascular disease Cancer Autoimmune diseases Multiple | |
sclerosis Pain Loss of Cognitive function Decreased strength Increased rate of all-cause mortality | |
3) “Deficiency of vitamin D is now recognized as a pandemic, with more than half of the world’s population at risk.” | |
4) Approximately 50% of the healthy North American population and more than 80% of those with chronic | |
diseases are vitamin D deficient. | |
5) 80% of healthy Caucasian infants are vitamin D deficient. [And the rate of vitamin D deficiency tends to be | |
greater in African American and Hispanic children]. | |
6) Those with vitamin D deficiency experience 39% higher annual healthcare costs than those with normal levels of vitamin D. | |
7) Suggested levels of vitamin D as measured by 25(OH)D3 is: Caucasians 125 – 175 nmol/l = 50 – 70 mg/dl | |
Hispanics 100 – 150 nmol/l = 40 – 60 mg/dl African Americans 80 – 120 nmol/l = 32- 48 mg/dl | |
8) The minimum blood levels of vitamin D [25(OH)D3] is 80 nmol/l (32 mg/dl). | |
9) Prolonged intake of 10,000 IU of supplemental vitamin D3 “is likely to pose no risk of adverse effects | |
in almost all individuals.” | |
10) The maximum safe levels for vitamin 25(OH)D3 in the blood is 275 nmol/l (100 mg/dl). | |
11) Sarcoidosis patients (and other granulomatous diseases) should not supplement with vitamin D because it increases | |
granuloma production increasing the risk of hypercalcemia | |
12) A loading dose of supplemental vitamin D3 of 10,000 IU/day for 3 months and maintenance dose of 5,000 IU/day | |
“is not enough for most people in northern climes.” | |
13) The loading dose of supplemental vitamin D3 should be about 20,000 IU/day for 3 – 6 months | |
with a maintenance dose of 5,000 IU/day. Those taking this amount of supplemental vitamin D3 | |
should periodically have their serum 25(OH)D3 levels measured. | |

KEY POINTS FROM DAN MURPHY |
|
1) It has been known for more than a century that sunlight can treat tuberculosis. | |
2) In 1895, Niels Finsen of Denmark effectively treated tuberculosis with exposure to high-intensity light produced | |
from an electric arc lamp. This phototherapy “cured or substantially improved the disease in about 95% of affected | |
people, and by the 1920s sun exposure for the treatment of pulmonary tuberculosis had become routine.” | |
3) Sunlight effectively treats tuberculosis because it produces vitamin D, which in turn produces a microbe- | |
fighting peptide. | |
4) Treating tuberculosis with sunshine was so effective that its discoverer was awarded the Nobel Prize in 1903. | |
5) Sunlight helps us battle tuberculosis and other microbes “by stimulating the synthesis of vitamin D, [which] | |
upregulates the expression of a microbe-fighting peptide.” | |
6) Vitamin D stimulates the synthesis of the potent antimicrobial peptide called LL-37 in skin and in circulating | |
phagocytic cells that make up the innate immune response. This improves the immune response. | |
7) Macrophages [innate immune response] more effectively kill tuberculosis after they are exposed to vitamin D3. | |
8) American blacks are particularly susceptible to infection by tuberculosis because they have substantially lower | |
serum vitamin D levels than whites, as a result of the greater UV shielding afforded by their skin's higher melanin | |
content. Treatment with vitamin D3 should augment the microbicidal capacity of monocytes in blacks. | |
9) “We currently base vitamin D requirements on amounts required to sustain optimal health of our skeleton. | |
The studies reported here suggest that optimal functioning of our innate immune system might require more vitamin D.” | |
10) “Perhaps in the future we might be able to treat or prevent certain infectious diseases with safe and inexpensive | |
substances that induce expression of endogenous antimicrobial peptides.” | |

RE: Epidemic Influenza and Vitamin D Epidemiology and Infection October 2007, Vol. 135, No. 7, pp. 1095-1098 JOHN F. ALOIA and MELISSA LI-NG
|
|
KEY POINTS FROM DAN MURPHY |
|
1) “There is an epidemic of vitamin D insufficiency in the United States, the public health impact of this observation | |
could be great.” | |
2) “The occurrence of the common cold and influenza shows clear seasonality. The cold and influenza season | |
corresponds to the season of vitamin D insufficiency.” | |
3) “The lack of vitamin D during the winter may be a ‘seasonal stimulus’ to the infectivity of the influenza virus.” | |
4) “Vitamin D is produced in the skin when sunlight is absorbed. Thus, vitamin D levels, or serum | |
25-hydroxyvitamin D (25-OHD), fluctuate seasonally.” | |
5) Vitamin D has important functions in the immune system, specifically the innate immune system. | |
6) Over a 3-year period, taking 800 IU of vitamin D3 reduced the incidence of colds and flu's by 70%. | |
Taking 2,000 IU of vitamin D3 reduced the incidence of colds and flu's to nearly zero (only one case out of 104 users). | |
7) “Vitamin D supplementation, particularly at higher doses, may protect against the ‘typical’ | |
winter cold and influenza.” | |
8) “The physiological basis of the protective effect of vitamin D lies in its ability to stimulate innate immunity | |
and to moderate inflammation.” | |
9) “These reports provide a rationale for vitamin D supplementation in the prevention of colds and influenza.” | |
10) Only vitamin D3 is bioactive; vitamin D2 (ergocalciferol) “is not vitamin D but a less potent vitamin D | |
analogue that plays no role in normal human physiology.” | |
11) “Physiological doses [800 – 2,000 IU / day] of vitamin D prevent many viral respiratory infections.” | |
12) “It is also reasonable to postulate that pharmacological doses of vitamin D may be effective adjuvants in | |
a breathtakingly large number of life-threatening infections.” | |

Vitamin D Supplementation and Total Mortality |
|
Archives of Internal Medicine |
|
KEY POINTS FROM DAN MURPHY |
|
1) “Low vitamin D status could be associated with higher mortality from life-threatening conditions including | |
cancer, cardiovascular disease, and diabetes mellitus that account for 60% to 70% of total mortality in | |
high-income countries.” | |
2) Vitamin D supplements are associated with decreases in total mortality rates. | |
3) UV-B radiation is between wavelengths 280-315 nm. UV-A radiation is between wavelengths 315-400 nm. | |
4) UV-B radiation reduces more rapidly than UV-A radiation with increasing distance from the equator and | |
with winter. | |
5) UV-B radiation is necessary for the synthesis of vitamin D in the skin. | |
6) Vitamin D is also found in oily fish, eggs, and butter. | |
7) The physiologically active form of vitamin D is dihydroxyvitamin D3 (calcitriol). | |
8) This study showed that 5.7 years of supplementation with between 400 – 833 IU of vitamin D / day | |
resulted in a 7% decrease in all cause mortality over that period of time. | |
9) Calcium supplements did not reduce all cause mortality, it was only the vitamin D that did so. | |
10) The intake of ordinary doses of vitamin D supplements is associated with decreases in total mortality rates. | |
11) Vitamin D is important in calcium and phosphorus homeostasis, bone health, cancer, cardiovascular disease, | |
diabetes, some infectious diseases, multiple sclerosis, and type-2 diabetes mellitus. | |
12) In this study,” individuals who supplemented with vitamin D had a statistically significant 7% reduction | |
in mortality from any cause, and the reduction was 8% for those who supplemented for at least 3 years.” | |
13) Vitamin D influences both incidence and survival of cancer. | |
14) Vitamin D has been shown to be critical for innate immunity and the production of antibiotic peptides, | |
and thus deficiency could contribute to diseases such as tuberculosis. | |
15) “As a species, we do not get as much sun exposure as we used to, and dietary sources of vitamin D are minimal.” | |
16) Given the high probability of benefit for at least some of the many conditions that have been associated | |
with vitamin D deficiency, and the low likelihood of harm, it seems prudent that physicians suggest supplementation. | |
17) “An individual with minimal sun exposure (e.g. a nursing home resident) may require 1000 to 2000 | |
IU/d to achieve levels of 30 to 40 ng/mL.” | |
18) “Ideally, the form of vitamin D used should be cholecalciferol (vitamin D3) rather than | |
ergocalciferol (vitamin D2), which may not be as effective | |

KEY POINTS FROM DAN MURPHY |
|
1) Higher serum levels of vitamin D3 are associated with substantially lower incidence rates of colon, breast, ovarian, | |
renal, pancreatic, aggressive prostate and other cancers. | |
2) Raising the minimum year-around serum vitamin D3 level to 40 to 60 ng/mL (100–150 nmol/L) would prevent | |
approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, | |
and three fourths of deaths from these diseases in the US and Canada. This would also reduce fatality rates of | |
patients who have breast, colorectal, or prostate cancer by half. | |
3) Raising serum vitamin D3 level 40 to 60 ng/mL would require supplementation with about 2,000 IU of | |
vitamin D3 per day. “There are no unreasonable risks from intake of 2,000 IU per day of vitamin D3.” | |
4) High sun exposure reduces both the incidence of and mortality from breast and prostate cancers. | |
5) Higher sun exposure in childhood and adolescence reduce the lifetime incidence of prostate cancer by about 50%. | |
6) “Approximately 220,149 new cases of breast cancer and 254,105 new cases of colorectal cancer would | |
be prevented annually in the world by raising serum vitamin D3 concentrations to approximately 40 to 60 ng/mL, | |
which is, in general, associated with oral intake of 2,000 IU of vitamin D3 per day.” | |
7) Vitamin D3 serum level of 40 to 60 ng/mL would prevent three fourths of deaths from breast and | |
colorectal cancer in the US and Canada. [Wow!] | |
8) There are ten separate mechanisms by which vitamin D3 and calcium reduce cancer incidence and mortality. | |
9) Preventing the spread of cancerous cells is dependent upon intercellular adherence. Intercellular adherence | |
is requires extracellular calcium ions. Low calcium levels thus allow the spread of cancer cells. | |
10) Intercellular adherence is also degraded by omege-6 vegetable oils. “Unfortunately, omega-6 linoleic acid | |
is the most common polyunsaturated fatty acid consumed in the Western diet (median intake 15 g/day).” | |
11) The “National Academy of Sciences–Institute of Medicine recommended adequate intake [of vitamin D3] | |
should be revised upward to at least 2,000 to 4,000 IU/day. Adoption of the new adequate intake [of vitamin D3] | |
would substantially reduce the incidence of cancer, and there are no consistently established adverse effects | |
of vitamin D3 intake in the range below 4,000 IU/day that would be sufficient to justify a lower adequate intake | |
of [vitamin D3].” | |
12) “The upper limit [of vitamin D3] should be increased to at least 5,000 IU/day, based on expected benefits | |
compared to anticipated minor risks.” Some knowledgeable vitamin D scientists and physicians have recommended a | |
higher upper limit of 10,000 IU/day. | |
13) Vitamin D3 (cholecalciferol) should replace vitamin D2 (ergocalciferol) because vitamin D3 is more effective in | |
humans. | |
14) “The preventive effects of higher vitamin D3 intake have led 16 vitamin D scientists and concerned physicians | |
in the US and Canada to disseminate a call to action recommending universal daily intake of 2000 IU of vitamin D3.” | |
15) Low vitamin D levels also increase the incidence of myocardial infarction, type-1 diabetes, multiple sclerosis, | |
and falls. | |
16) “Populations living at or higher than 30° latitude in either the northern or southern hemisphere, | |
or who have a mainly indoor lifestyle, should be considered at high risk of breast, colon, ovarian, and many | |
other types of cancer as a result of highly prevalent vitamin D deficiency.” | |
17) Vitamin D should be used to “reduce incidence and mortality from cancer, and substantially increase treatment | |
success.” | |

On the Epidemiology of Influenza Virology Journal February 25, 2008, Volume 5 John J Cannell, Michael Zasloff, Cedric F Garland, Robert Scragg and Edward Giovannucci
|
|
KEY POINTS FROM DAN MURPHY |
|
1) Vitamin D upregulates the endogenous antibiotics of innate immunity and suggest that the incongruities | |
in flu behavior may be secondary to the epidemiology of vitamin D deficiency. | |
2) Recently epidemiological studies question vaccine effectiveness because “influenza mortality and hospitalization | |
rates for older Americans significantly increased in the 80's and 90's, during the same time that influenza vaccination | |
rates for elderly Americans dramatically increased.” | |
3) A 2006 study stated “We found no evidence of reduction in influenza-related mortality in the last 15 years, | |
despite the concomitant increase of influenza vaccination coverage from ~10% to ~60%.” | |
4) The seasonality of influenza indicates that it is controlled by a “seasonal stimulus.” This “seasonal stimulus” | |
may be seasonal impairments of the antimicrobial peptide systems crucial to innate immunity caused by dramatic | |
seasonal fluctuations in vitamin D3. | |
5) Innate immunity is that branch of host defense that is “hard-wired” to respond rapidly to microorganisms. | |
6) “The evidence that vitamin D has profound effects on innate immunity is rapidly growing.” “Vitamin D is the | |
‘antibiotic vitamin’ due primarily to its robust effects on innate immunity.” | |
7) In a 2007 study, 104 women given vitamin D were three times less likely to report cold and flu symptoms than | |
placebo controls. “A low dose (800 IU/day) not only reduced reported incidence, it abolished the seasonality of | |
reported colds and flu. A higher dose (2000 IU/day), given during the last year of their trial, virtually eradicated all | |
reports of colds or flu.” | |
8) “Relative – but easily correctable – deficiencies in innate immunity probably exist in many dark-skinned and aged | |
individuals, especially during the winter,” because of reduced ability to produce vitamin D. | |
9) During the 1918 flu pandemic, there were five attempts to transmit the flu to a well person from a sick person, and | |
these attempts exceeded a combined total of 150 well patients. Methods of transmission included cough, spit, and | |
breathe. None of these attempts succeeded. [Very Interesting] | |
10) In previous ages, flu
epidemics spread rapidly despite the lack of modern transport
because influenza was already embedded in the population and erupted when impairments in innate immunity occurred as a consequence of seasonal |
|
reduced vitamin D. | |
11) These authors propose individual variations in vitamin D3 levels explain the variations in the innate immunity of the | |
volunteers who purposefully exposed themselves to the flu but did not become ill. | |
12) Influenza mortality has not declined with increasing vaccination rates because influenza vaccines improve adaptive | |
immunity, and the key is innate immunity. [The innate immune response rules the adaptive immune response: if | |
the innate immune response ignores an invader, one will not make antibodies {adaptaive immune response} | |
to that invader How the Immune System Works, by Loren Sompayrac, Blackwell Science, 2008] | |
“The innate immunity of the aged declined over the last 20 years due to medical and governmental warnings to avoid | |
the sun. While the young usually ignore such advice, the elderly often follow it. We suggest that improvements in | |
adaptive immunity from increased vaccination of the aged are inadequate to compensate for declines in innate immunity | |
the aged suffered over that same time.” | |
13) “Compelling epidemiological evidence indicates vitamin D deficiency is the ‘seasonal stimulus’ [responsible for flu | |
outbreaks].” | |
14) Lower respiratory tract infections are more frequent in those with low vitamin D3 levels. | |
15) Vitamin D3 regulates 1,000 human genes. | |
16) A 2007 study found 2,000 IU of vitamin D per day “abolished the seasonality of influenza.” | |
