latitude & the incidence of disease: overwhelming proof that vitamin d3 deficiency causes most human diseases (please note- A major analysis published in 2009 pooled together the results of 394 studies examining vitamin D levels in over 30,000 people all across the globe in order to investigate the effect of latitude on vitamin D status. The authors only included people who were native to the area in which they were living, and who were free-living The latitude studies are observational - as opposed to interventional - studies that use ambient solar UV radiation as a proxy for latitude and vitamin D status. For these studies, researchers compare rates of certain major cancers - most notably breast, colorectal and prostate cancer - to rates of sunlight exposure. This group of research has the liability of being wildly inconsistent A good way to test if the sun is about 50 degrees above the horizon, or higher, is that your shadow should be slightly shorter than you are tall. If the shadow cast by your body is the same length, or longer, than your height you will not produce Vitamin D-even while your skin is exposed to direct sunlight
That answer is sunlight and vitamin D. Low latitudes (closer to the equator) receive much more sunlight, and sunlight is more direct much of the year. A study of latitude backs the efficacy of sunlight, and possibly vitamin D, on reducing the risk of Covid-19. This was a large, study, drawing reliable data from 88 countries The UV index offers a scale which allows you to measure the intensity of the UV rays. The highest UV intensity is reached when the sun is at its highest point in the day, halfway between sunrise and sunset — called solar noon. This is usually between 11.30 and 12.30 (or 12.30 and 1.30 in locations where daylight saving is being observed)
Vitamin D's major biologic function in humans is to maintain Latitude, time of day, and season of the year have a dramatic influence on the cutaneous production of vitamin D 3. Above and below latitudes of approximately 40° N and 40° S, respectively, vitamin D 3 synthesis in the skin is absen Because vitamin D is fat soluble upon its ingestion or production in the skin vitamin D 3 gets incorporated into the body fat and is also transported to the liver to be converted to 25(OH)D. 22, 73, 171-174 As a result to treat vitamin D deficiency and prevent recurrence, vitamin D can be given daily, weekly and even monthly with the same. It is well documented that short days and weak sunlight do not trigger vitamin D synthesis in the skin at latitudes above 40 degrees North (10, 12) where the population relies on dietary rather than light-synthetized vitamin D (13). Two forms of vitamin D are present: D2 and D3, ergocalciferol, and cholecalciferol, respectively
RxFiles Q&A Summary Revised T Rawn Nov'17 - Originally Prepared by S Stone, L Regier - www.RxFiles.ca Vitamin D: Therapeutic Overview & Evaluation of Evidence for Current Claims 1,2,3,4 5 Vitamin D deficiency in Canada (see Table 1 below for significance of level) Statistics Canada: 32% of Canadians have levels < 50nmol/L (25% in summer, 40% in winter), an Vitamin D is likely beneficial for other parts of the body as well; studies suggest an overall decrease in death in addition to reductions in blood pressure, respiratory illnesses, cancer, heart disease, and depression. Adequate vitamin D during pregnancy also appears to reduce the chances of having a low-birthweight baby
. Scientists at the Norwegian Institute for Air Research have devised a calculator that will take all those factors into consideration and estimate how many minutes of exposure you need for your skin to produce 25 mcg (the equivalent of 1,000 International Units) of vitamin D This supports a role for ultraviolet B acting via vitamin D synthesis. Factors associated with worse COVID‐19 prognosis include old age, ethnicity, male sex, obesity, diabetes and hypertension and these also associate with deficiency of vitamin D or its response. Vitamin D deficiency is also linked to severity of childhood respiratory illness Vitamin D deficiency is a problem all over the world. However, it's pervasive in young women, infants, older adults, and people who have dark skin (12, 13, 14).About 42% of the U.S. population.
Vitamin D tocicity is quite rare adn easy to correct, a new article>> Vitamin D toxicity is rare, and usually a result of accidental overdosing, according to recent study Posted on: January 24, 2018 by Vitamin D Council Interest in vitamin D supplementation and testing has increased over the last few decades By the current blood test for vitamin D, most African-Americans are deficient. That can lead to weak bones. So many doctors prescribe supplement pills to bring their levels up. But the problem is. There are three ways to get vitamin D and help prevent a vitamin deficiency: Sun exposure: As noted earlier, getting a limited amount of sun exposure may help your body get enough D. Check with your physician to see how much sunlight is safe. A common recommendation is about 20 minutes of sun several times a week—not a problem in Five Star. According to the chart, someone with skin type 1 would need to bare 50 to 75 percent of their skin to sunlight for 10 to 15 minutes, when the UV Index is between 3 and 5. Doing so several times per would likely get them to an optimal level of vitamin D. Someone with skin type III, meanwhile, would need 40 or more minutes in the sun to produce. 11740 COVID-19 mortality rate highest North of 35 degrees latitude (Vitamin D) - April 20, 2020 983 21 Apr, 2020 12:16 11702 Clear Association between Influenza and low Vitamin D - March 2020 739 20 Apr, 2020 16:55 Select action to perform with checked Vitamin D is the 3rd most important contributor to health

Lack of sun exposure and inadequate oral intake are both responsible for vitamin D deficiency. This article provides a retrospective, examining the effects of Vitamin D deficiency in 71 patients. The study's inclusion criterion was low vitamin D level combined with musculoskeletal symptoms but without the presence of. Vitamin D is an essential nutrient for the body. The body needs vitamin D to absorb calcium.Vitamin D also plays a role in bone growth, bone healing, and immune system function. This article looks. Vitamin D plays three key roles in bone health: Helps with calcium absorption from food in the intestine. Ensures the correct renewal and mineralization of bone. Helps to keep muscles strong and so reduces the risk of falling. Vitamin D is made in the skin when the skin is exposed to UV-B rays in sunlight. Only a limited number of foods contain. Your latitude is the geographic coordinate that states your north-south position on the surface of the Earth. You can find your latitude by using the Internet, a real map, by making a compass, or by using a few other tricks. If you want to know how to find your latitude, see Step 1 to get started
Calculates a table of changes in the solar elevation and azimuth angles for a day and draws the chart. Input negative degree for west longtitude and south latitude. If your local time is on Daylight Saving time, select 'ON' from DST mode When you can make vitamin D is also dependent on latitude and season. Those who live closer to the equator, where the midday sun is high in the sky throughout the year, have the ability to produce vitamin D year-round, whereas those north of about 34 degrees latitude (approximately Los Angeles, CA, or Atlanta, GA) experience a vitamin D. Latitude and Season - those closer to the equator have the ability to produce vitamin D year-round, while areas located north of 34 degrees latitude (approximately Los Angeles, CA, or Atlanta, GA) experience a varying degree of Vitamin D Winter Those with dark skin however, at the 38th latitude north of the equator, would need from 2100 to 3100 IU total vitamin D per day year round. By comparison, typically recommended intakes have been on the order of 400-800 IU per day The highest mortality rates of COVID-19 have been generally reported in countries with lower average levels of vitamin D or above the [37th parallel north] geographic latitude line, where the.
Vitamin D Deficiency Here is a chart of vitamin D blood level distribution by race. Dark skin blocks vitamin D production, and therefore causes vitamin D deficiency. Black people living at northern latitudes are most severely deficient and for them vitamin D supplementation is essential Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and many other biological effects. In humans, the most important compounds in this group are vitamin D 3 (also known as cholecalciferol) and vitamin D 2 (ergocalciferol).. The major natural source of the vitamin is synthesis of cholecalciferol in the lower. Vitamin D, or calcidiol, has a half-life -- meaning it stays in your blood for 15 days before half of the level is gone. This is a strong indicator of how well your body is manufacturing vitamin D for bone development and your overall well-being. Yet, calcidiol is inadequate in reflecting vitamin D stores in the body Here is how a dosage affects blood levels on average:  100 IU (2.5 mcg) per day increases vitamin D blood levels 1 ng/ml (2.5 nmol/L). 500 IU (12.5 mcg) per day increases vitamin D blood levels 5 ng/ml (12.5 nmol/L). 1000 IU (25 mcg) per day increases vitamin D blood levels 10 ng/ml (25 nmol/L) Babies in northern communities (north of 55° latitude, which is about the level of Edmonton) or who have other risk factors (such as dark skin) should get 800 IU per day between October and April, where there is less sunlight. *Range of vitamin D levels in breast milk, measured in lactating women taking a daily vitamin D supplement of 400 IU
Vitamin D3 is the form you find naturally in foods like fish eggs or salmon or oysters or other foods rich in vitamin D. Also, 50,000 IU once a week is kind of strange dosing. Most health care providers will recommend a smaller, daily dose of D3 The most accurate way to measure how much vitamin D is in your body is the 25-hydroxy vitamin D blood test. A level of 20 nanograms/milliliter to 50 ng/mL is considered adequate for healthy people Vitamin D is added to milk and other dairy products, orange juice, soymilk, and fortified cereals. Check the food label to see if vitamin D has been added to a particular product. One eight-ounce serving of milk usually has 25% of the daily value (DV) of vitamin D. The DV is based on a total daily intake of 400 IU of vitamin D
The study of the relationship between vitamin D levels and cancer mortality has been based largely on latitude or other surrogates for exposure to solar radiation, not vitamin D itself ( 6, 7, 10). There has, however, been one randomized controlled 5-year trial of triannual high oral doses of vitamin D that evaluated cancer mortality The UV Index must be over 3 to make vitamin D, which usually occurs around midday between 10am and 2pm. UV Index varies tremendously depending on the time of day, time of year, latitude, weather, air pollution, and geographical location
Vitamin D supplement. 5000-6000 units of vitamin D every day no matter the season. Dr. Holik's recommendations for ideal levels of vitamin D. Minimum 30 ng/ml, however 40-60 ng/ml is ideal. Max 100. Over 150 - 200 is dangerous. Dr. Holik's guidelines for obtaining adequate sun exposure. Obtain unprotected, non-burning, sun exposure maintain vitamin D levels in the body.(7) Factors such as seasons and latitude can play a role in vitamin D synthesis, for example less vitamin D is synthesised in winter, particularly at latitudes further from the equator. Figure 1: Synthesis of vitamin D Rates of vitamin D deficiency <20ng/ml exceed 33% of the population in most of the world, and most estimates of insufficiency <30ng/ml are well over 50% (but much higher in many countries). 3 Rates are even higher in winter, and several groups have notably worse deficiency: the overweight, those with dark skin (especially far from the equator. .e., rickets), but a heightened sensitivity to a host of diseases. The map to the left is a rough sketch of variation in skin color.
You might have noticed that the days are getting shorter up here underneath the 49th Parallel (aka Canada's Waistband). It's not your imagination, it's true! Insolation is a climatological term for Incoming Solar Radiation, or the total amount of the sun's energy that strikes the Earth during a day. This number varies quite a lot depending on latitude and time of year Daily treatment with Vitamin D (either cholecalciferol or ergocalciferol) is associated with a rise in measured vitamin D levels, representing an increased amount of stored Vitamin D. In adults, each 100 units of vitamin D taken daily will normally raise vitamin D levels by 2.5 nmol/L (1 μg/L)
The Vitamin D Society recommends people achieve and maintain optimal 25 (OH)D blood levels between 100 - 150 nmol/L (Can) or 40-60 ng/ml (USA). To learn more about vitamin D, please visit www.vitamindsociety.org. Mike Kwiatkowski, Enterprise Canada 905-346-1235 firstname.lastname@example.org Jul 11, 2017. By Perry Holman, Executive Director, Vitamin D Society. A new study 1 recently reported trends in vitamin D supplementation in the USA from 1999 to 2014. It found that that vitamin D supplement use of ≥1000 IU or more per day increased from 0.3% in 1999 to 18.2% in 2014
A&E Mega-dosing vitamin D: Doctor-prescribed 50,000 IU vitamin D may be right for some patients. Thu., Nov. 1, 2018. Some health care providers are prescribing a mega-dose, 50,000 IU vitamin D. The best foods for increasing vitamin D intake are lard, some seafood including fatty fish, cod liver oil, and egg yolk. Lard has 13 IUs of Vitamin D per tablespoon, which still takes a while to add up if you're going for 5000. Per 100 grams (3 ½ ounces), Vitamin D shows up in the following amounts
Even if you are deficient in vitamin D right now, if you take 2000 IU per day you will, after several months, reach and maintain a level of vitamin D of around 25-35 ng/ml, which is an adequate level. 2000 IUs of vitamin D3 is probably less than half your optimum dosage. Even so, it is enough to protect you from the effects of vitamin D deficiency A study in Argentina assessed the effect of latitude on vitamin D status. They found those living in the South had the lowest mean 25(OH)D levels (35.4nmol/l) compared to the mid region (44.7nmol/l) and North (51.7nmol/l) of the country (103). Oceania. Vitamin D deficiency is seen in a number of at risk groups within Australia
Salmon is a great choice. A 3.5 ounce serving of salmon contains between 360 IU and 1,300 IU according to nutrient databases. Whether it's wild or farmed also makes a difference. A 2009 study, for example, found that wild-caught salmon contains 988 IU of vitamin D for a 3.5 ounce (300 gram) serving Free online Vitamin D calculator. It's been brought to my attention that we may not be getting Vitamin D through sunlight during certain months of the year. However there is a calculator HERE that enables you to put in your latitude and longditude, height above sea level and after you have selected whether it is cloudy or not, will work out how. 25-hydroxy-vitamin D of 30-50 nmol/L is mildly deficient. 25-hydroxy-vitamin D of greater than 50 nmol/L is sufficient for the health of bones. Vitamin D levels should be higher at the end of summer to allow for a decrease in levels over winter. Your doctor may recommend a vitamin D supplement if your vitamin D level is below this target level
Vitamin D is an essential fat-soluble vitamin that supports healthy bones and muscles, your cardiovascular health, and your immune function,* at every stage of life, beginning with fetal development through your golden years. Although direct sunlight exposure is a great source of vitamin D, because of seasonal changes The study also showed Norway, Finland and Sweden in the northern latitude have higher vitamin D levels despite less UVB sunlight exposure because supplementation and fortification of food is more common. The correlation between lower vitamin D levels and death from COVID-19 is significant Get your 25 (OH)D levels tested before you start supplementation, take the 4k IU daily, and get them tested again after two months. Aim to get your levels up around 50-60 ng/mL, which is where most of the big benefits seem to kick in. If you don't respond well to 4000 IU, feel free to increase the dosage They then plotted incidence rates for 51 regions according to latitude. The resulting chart was a parabolic curve that looks like a smile. In the paper the researchers call for public health action to address widespread vitamin D inadequacy in U.S. children
vitamin D, whether vitamin D protects against chronic diseases such as cancer, heart disease and diabetes, and the benefits and risks of widespread supplementation. The amount of UVB in sunlight changes substantially with season, latitude and time of day. 11 These factors greatly affect vitamin D production, which is greatest around two. Vitamin D deficiency interacts with latitude, altitude, sunlight, diet, air pollution, cigarette smoking, age, air pollution, skin color, obesity and all of these factors came together in places like Wuhan and Teheran and Seattle and New York. B-type Ultraviolet light (280-315 nm) (UVB), the frequency of light at which vitamin D is produced in. And, sunlight may have benefits beyond vitamin D, like the amazing story about how your body may use the sun's near-infrared rays that penetrate your skin to activate chlorophyll by-products in your bloodstream to make Co-Q10. Well, there's another way your body appears to use the sun's rays to maximize the effects of the greens we eat 1. Introduction. Vitamin D deficiency, as determined by serum concentrations of 25(OH)D [ie., the sum of 25(OH)D 3 and 25(OH)D 2] is known to compromise musculoskeletal health , .This knowledge has spurred an increase in demand for 25(OH)D testing which has led many laboratories to replace radioactive methods with fully automated immunoassays
5) Season Americans' vitamin D levels vary throughout the year, peaking in August and receding around February. In general, vitamin D levels have been shown to be the lowest during the winter months. In the summer, when the Earth rotates, the angle of sun hitting the atmosphere is optimized for vitamin D production because more UVB reaches the places far away from the equator Vitamin D helps the body absorb calcium, which supports the development and maintenance of healthy bones. Insufficient amounts of it, especially in children, can cause a condition called rickets, a softening of the bones, making patients more prone to fractures and deformities. Seattle's latitude and propensity for cloudy days make it.
As the world's attention has been riveted upon the growing COVID-19 pandemic, many researchers have written brief reports supporting the hypothesis that vitamin D deficiency is related to the incidence and severity of COVID-19. The clear common thread among the top risk groups—vitamin D deficiency—may be being overlooked because of previous overstated claims of vitamin D benefits Most multivitamins have between 200 to 800 IU's of Vitamin D. To give you more context of how much vitamin d you need, a study done on a team at McMurdo Station in Antarctica during the winter (where there is no vitamin D) supplemented with 2000 IU's of Vitamin D per day, and the average blood level was 22 ng/ml (71 nm/l)
Latitude studies - The latitude studies are observational, as opposed to interventional, studies, which use ambient solar UV radiation as a proxy for latitude and vitamin D status. For these studies, researchers compare rates of certain major cancers - most notably breast, colorectal and prostate cancer - to rates of sunlight exposure The relationship between vitamin D deficiency and adverse prognosis has been suggested by the apparent Northern-Southern latitude gradient, with mortality and hospitalisation rates for COVID-19 seen to be higher in northern latitude countries compared with those closer to the equator. 1 Furthermore, research by Alipio and colleagues 2, in a. Some governments are starting to recognise the importance of vitamin D supplementation for population heatlth. Israel started recommending vitamin D in October 2020.; Slovenia has begun administering vitamin D to residents of nursing homes and health care workers.; The French National Academy of Medicine recommends that people over 60 be tested for vitamin D deficiency and given a bolus dose. Vitamin D deficiency is typically diagnosed by measuring the concentration of the 25-hydroxyvitamin D in the blood, which is the most accurate measure of stores of vitamin D in the body. One nanogram per millilitre (1 ng/mL) is equivalent to 2.5 nanomoles per litre (2.5 nmol/L).. Severe deficiency: <12 ng/mL = <30 nmol/L; Deficiency: <20 ng/mL = <50 nmol/
Both produce what we call vitamin D when exposed to UV light. I can't really make any recommendations as to how to improve that process other than recommend living in an environment or latitude that is more conducive to an overall healthier lifestyle Vitamin D insufficiency is prevalent in almost half of the healthy population of developed countries .Risk factors for low 25(OH)D levels are advanced age, female sex, darker skin pigmentation, less sunlight exposure (due to latitude, clothing, or prolonged periods indoors), reduced intake of vitamin D through diet, and the winter season .4 Vitamin D is one of the most intensely studied yet widely debated nutrients in health research over the past decades. The research debate over vitamin D has focused partly on its roles in the body, and more recently on its optimal levels in the body and on the relationship of those levels to dietary intake. Since vitamin D was first recommended.
