Inspiration says: "Invalids too often deprive themselves of sunlight. This is one of nature's most healing agents. It is a very simple, therefore not a fashionable remedy, to enjoy the rays of God's sunlight and beautify our homes with its presence....It is not God who has brought upon us the many woes to which mortals are heirs. Our own folly has led us to deprive ourselves of things that are precious, of blessings which God has provided and which, if properly used, are of inestimable value for the recovery of health. If you would have your homes sweet and inviting, make them bright with air and sunshine...." Ellen White, Testimonies, Vol 2:527.
"Let your judgment be convinced that exercise, sunlight, and air are the blessings which Heaven has provided to make the sick well and to keep in health those who are not sick." --Ibid, 535.
A word to the wise!!!! We nowadays tend to forget that sunshine is one of the eight remedies cited by Ellen White to prevent and cure illness. Thre is too much use of sunblocks.

Vitamin D Needs in Pregnancy
A study published in the British Journal of Nutrition identifies pregnant women, especially if dark skinned, as a high-risk group for vitamin D deficiency. The article states that severe vitamin D deficiency can threaten the life of newborns, while lesser deficiencies may cause long-term health problems.
While a supplemental dose of 20 micrograms per day has been previously recommended for pregnant mothers, new research indicates that higher doses may be required. Further research is needed, since inconsistent advice by doctors undercuts prevention strategies and may lead to some mothers going without any supplementation at all. --British Journal of Nutrition,= August 2010.

Vitamin D Scorecard
Brain
High blood levels linked with 67% reduction in Parkinson's disease risk (Archives of Neurology, July 2010); low levels may increase the risk of depression (Journal of Clinicl Endocrinology & Metabolism, July 2010) and cognitive decline (Archives of Internal Medicine, July 12, 2010).
Bones
Long known to help the body maintain calcium levels, a key requirement for proper bone mineralization; prenatal D intake by mothers required for proper fetal bond development (Journal of Nutrition, Sept. 2010).
Heart
Low levels of Vitamin D have been linked to hypertension, and lab studies indicate supplementation may help lower blood pressure (American Journal of Physiology, Aug. 6, 2010 online); Low levels of this nutrient are also associated withy poor outcome in heart failure patients (Current Drug Targets, Aug. 27, 2010 online) and increased risk of metabolic syndrome, a risk factor for heart disease and diabetes (Endocrine Society meeting, July 2010).
Immune System
Vitamin D helps activate the immune system's T cells (Nature Immunology, April 2010); increased intake may reduce flu risk (American Journal of Clinical Nutrition, May 2010).
Other
Increased intake of this nutrient linked to 40% reduction in colorectal cancer risk (American Journal of Epidemiology, Sept. 1, 2010); may reduce mold allergies in those with asthma (Journal of Clinical Investigation, Aug. 16, 2010 online).
Note: The current recommended daily intake of vitamin D is 400 IU for folks 50 and older. In light of ongoing research, however, the Institute of Medicine's Food and Nutrition Board is expected to recommend an increase in this amount; some studies support intakes as high as 5,000 IU. --Energy Times, October 2010.

Vitamin D discoveries keep growing -- lack of vitamin D linked to muscle injuries and Alzheimer's disease
by S. L. Baker, features writer
(NaturalNews) Over the past few years, researchers have come up with a mountain of evidence that vitamin D is extremely important to maintaining health and preventing and even treating a host of health problems. For example, studies have shown that too little vitamin D may trigger breast cancer, rheumatoid arthritis (http://www.naturalnews.com/028690_R...)
, brittle bones, heart attacks (http://www.naturalnews.com/025069_V...)
and more.
And now there's breaking news that scientists have discovered two more extraordinary benefits to getting enough vitamin D through sun exposure and supplements. It turns out a lack of the remarkable vitamin could result in sports-related muscle injuries. What's more, vitamin D may, in a sense, help "vacuum" out plaques in the brain associated with the dreaded, mind-robbing dementia known as Alzheimer's disease.
A recent study just presented at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting now underway in San Diego has linked too little vitamin D in the body to an increased risk of muscle injuries in athletes. Specifically, the scientists studied National Football League (NFL) football players.
"Eighty percent of the football team we studied had vitamin D insufficiency. African American players and players who suffered muscle injuries had significantly lower levels," said Michael Shindle, MD, lead researcher and member of Summit Medical Group, in a statement to the press.
The researchers worked with 89 football players, average age 25, from a single NFL team, giving them laboratory tests to measure vitamin D levels in the spring 2010 as part of the athletes' routine pre-season evaluations. Over the course of the season, the team provided data to the scientists so they could document how many of players missed games due to muscle injuries. Vitamin D levels were also classified according to a player's race and how much playing time was lost due to muscle injuries.
The results showed that a large number of these super fit, professional athletes were actually seriously deficient in vitamin D. Twenty-seven players were dramatically deficient and 45 more had levels consistent with insufficiency. In fact, only 17 players tested had values in the normal limits. African American players were far more likely to have the lowest levels of vitamin D. And the 16 players who suffered muscle injuries were found to have the lowest vitamin D levels.
"Screening and treatment of vitamin D insufficiency in professional athletes may be a simple way to help prevent injuries," Dr. Scott Rodeo, MD, Co-Chief of the Sports Medicine and Shoulder Service at the Hospital for Special Surgery, noted in the press statement.
While preventing sports injuries with vitamin D is an exciting possibility, consider this other, potentially mind blowing news about the remarkable vitamin -- it may help prevent and even reverse the buildup of amyloid beta plaques in the brain that are associated with Alzheimer's disease.
That's the conclusion of new research just published in BioMed Central's open access journal Fluids and Barriers of the CNS. A lack of vitamin D has been suspected to play a role both Alzheimer's disease and less serious but worrisome age-related memory problems. And now a study conducted by scientists at Tohoku University in Japan has found that removal of amyloid plaques from the brain depend on vitamin D.
The researchers treated mice bred to have amyloid beta plaques in their brains with injections of vitamin D. The result? The vitamin D therapy actually helped remove these plaques, which are the hallmark of Alzheimer's disease, from the rodents' brains.
"Vitamin D appears to increase transport of amyloid beta across the blood brain barrier (BBB) by regulating protein expression, via the vitamin D receptor...These results lead the way towards new therapeutic targets in the search for prevention of Alzheimer's disease," Professor Tetsuya Terasaki said in a media statement.
Editor's note: NaturalNews is opposed to the use of animals in medical experiments that expose them to harm. We present these findings in protest of the way in which they were acquired.

Optimum vitamin D blood saturation reduces all-cause mortality by nearly thirty percent
by John Phillip
(NaturalNews) The importance of vitamin D for human health has been the topic of extensive research over the past decade. Suboptimal levels of the prohormone are known to compromise immunity, cardiovascular health, bone health and normal metabolism. The result of a new meta-analysis study published in the European Journal of Clinical Nutrition shows that adequate circulating vitamin D reduces the risk of all-cause mortality by 29 percent. Vitamin D has been shown to provide the blueprint required for healthy DNA replication of cellular structures; low levels of the sunshine vitamin dramatically increase the incidence of many cancer lines as genetic mutations proliferate. Millions of at-risk people can protect themselves by ensuring normal blood saturation levels through a simple blood test and prudent sun exposure or supplementation.
Vitamin D deficiency runs rampant in the aging population around the world. Researchers estimate that correcting this deficiency by doubling the typically low vitamin D levels would result in a 20 percent mortality reduction. A body of evidence shows that senior adults with the lowest level of vitamin D blood saturation more than double their risk of cardiovascular disease and mortality.
Vitamin D blood level lowers colorectal cancer risk by forty percent
Researchers performed a large meta-analysis of eleven vitamin D studies including 59,231 individuals. They compared individuals in the highest quartile with those in the lowest quartile and found the increased risk of early morality from all causes was 29 percent. As blood levels dropped below 30 ng/mL, the risk for death went up in a linear manner. It is important to note that fifty-percent of U.S. citizens have vitamin D levels below 30 ng/mL and forty percent have major deficiency (below 20 ng/mL), problems made worse by lack of sun exposure in the winter.
In an independent and supporting body of research, scientists from the national cancer Center in Tokyo publishing in the American Journal of Epidemiology found that the highest levels of vitamin D blood saturation lowered the risk of colorectal cancer by forty percent. In a study of 737 people with colon cancer and 703 cancer-free individuals, researchers found that those with the highest levels of vitamin D and increased levels of calcium experienced the lowest risk from this common form of cancer.
World-renowned vitamin D expert, Dr. Michael Holick commented "maintaining optimal vitamin D status is important for reducing risk of colorectal cancer independent of the calcium effect." Nutrition experts recommend maintaining vitamin D levels between 50 and 70 ng/mL as measured by a 25(OH)D blood test. New evidence suggests that calcium provided from natural food sources (590 mg per day) provides a synergistic effect with vitamin D to dramatically lower all-cause mortality.

The 10 symptoms of vitamin D deficiency you need to recognize
by Aurora Geib
(NaturalNews) Taking vitamin D while still young may be good for the body in the long run. Results from a study conducted by the University of Zurich have confirmed that sufficient amounts of vitamin D taken consistently are necessary to maintain bone health.
Many people believe that maintaining healthy eating habits is enough, but only few foods naturally contain significant levels of vitamin D. According to Dr. Heike A. Bischoff-Ferrari, a faculty of UZH, in order to get adequate levels of vitamin D through diet alone, two servings of fatty fish like salmon or mackerel would have to be consumed every day. It is thus necessary to increase vitamin D levels in the body through sufficient sun exposure and supplementation in order to use the sunshine vitamin's full potential for maintaining proper body functioning.
This misconception about maintaining D levels through diet does have a degree of ground since vitamin D is not a stand alone vitamin. To perform many functions, vitamin D works in cooperation with other vitamins like magnesium, which can be found in leafy green vegetables such as spinach. This unique characteristic of vitamin D has contributed to the management of many chronic illnesses.
The many faces of vitamin D
Decades ago, health care professionals thought vitamin D was only good for keeping healthy bones and teeth. Recent advances in science, however, have put this vitamin in the spotlight by revealing its multifaceted role in the proper functioning of the human body and its ability to lower the risk of illnesses not formerly associated with it.
Despite the recent revelations about the potential of vitamin D, it appears that not everyone appreciates this discovery. The current lifestyle of working indoors has contributed to the growing number of vitamin D deficiency cases worldwide. This is compounded by the fact that not everyone is aware that he or she may be vitamin D deficient.
Am I vitamin D deficient?
The best way to discover vitamin D deficiency is to take a blood test that will measure the level of the vitamin in your blood. You can either ask your doctor to administer the test or buy a home test kit do the test yourself. However, you are certainly vitamin D deficient if you have any of the following ailments, and you need to consult with your doctor regarding your preventive, as well as curative, options as soon as possible.
1.) The flu - In a study published in the Cambridge Journals, it was discovered that vitamin D deficiency predisposes children to respiratory diseases. An intervention study conducted showed that vitamin D reduces the incidence of respiratory infections in children.
2.) Muscle weakness - According to Michael F. Holick, a leading vitamin D expert, muscle weakness is usually caused by vitamin D deficiency because for skeletal muscles to function properly, their vitamin D receptors must be sustained by vitamin D.
3.) Psoriasis - In a study published by the UK PubMed central, it was discovered that synthetic vitamin D analogues were found useful in the treatment of psoriasis.
4.) Chronic kidney disease - According to Holick, patients with advanced chronic kidney diseases (especially those requiring dialysis) are unable to make the active form of vitamin D. These individuals need to take 1,25-dihydroxyvitamin D3 or one of its calcemic analogues to support calcium metabolism, decrease the risk of renal bone disease and regulate parathyroid hormone levels.
5.) Diabetes - A study conducted in Finland was featured in Lancet.com in which 10,366 children were given 2000 international units (IU)/day of vitamin D3 per day during their first day of life. The children were monitored for 31 years and in all of them, the risk of type 1 diabetes was reduced by 80 percent.
6.) Asthma - Vitamin D may reduce the severity of asthma attacks. Research conducted in Japan revealed that asthma attacks in school children were significantly lowered in those subjects taking a daily vitamin D supplement of 1200 IU a day.
7.) Periodontal disease - Those suffering from this chronic gum disease that causes swelling and bleeding gums should consider raising their vitamin D levels to produce defensins and cathelicidin, compounds that contain microbial properties and lower the number of bacteria in the mouth.
8.) Cardiovascular disease - Congestive heart failure is associated with vitamin D deficiency. Research conducted at Harvard University among nurses found that women with low vitamin D levels (17 ng/m [42 nmol/L]) had a 67 percent increased risk of developing hypertension.
9.) Schizophrenia and Depression - These disorders have been linked to vitamin D deficiency. In a study, it was discovered that maintaining sufficient vitamin D among pregnant women and during childhood was necessary to satisfy the vitamin D receptor in the brain integral for brain development and mental function maintenance in later life.
10.) Cancer - Researchers at Georgetown University Medical Center in Washington DC discovered a connection between high vitamin D intake and reduced risk of breast cancer. These findings, presented at the American Association for Cancer Research, revealed that increased doses of the sunshine vitamin were linked to a 75 percent reduction in overall cancer growth and 50 percent reduction in tumor cases among those already having the disease. Of interest was the capacity of vitamin supplementation to help control the development and growth of breast cancer specially estrogen-sensitive breast cancer.
Prevention is proactive
These various health conditions associated with vitamin D deficiency need not be something to fear. A proactive approach to prevention can assist in the avoidance of the many chronic diseases associated with vitamin D deficiency. For one, thousands of dollars can be saved, not to mention the peace of mind, simply at the cost of taking a walk under the sun. Save the umbrellas for the rainy days.

How vitamin D helps prevent lung cancer
by Aurora Geib
(NaturalNews) Increasing vitamin D may now be a matter of life or death, as recent studies have shown that it may play a vital role in the fight against lung cancer. To date, lung cancer is one of the three most common cancers that kill men and women in developed countries with a statistic of one million deaths every year.
Researchers from the University of California at San Diego discovered a correlative relationship between higher rates of lung cancer and less exposure to the sun.
Cancer and vitamin D
The study compared data from national and international databases and compared the lung cancer rates in 111 countries. It found a correlation with smoking, lung cancer and significant lower UVB exposure. Although the current study focused only on lung cancer, research conducted on other cancers have pointed to the fact that most cancer cases are seen in subjects living far from the equator, suggesting that lower levels of vitamin D also account for a high risk of colon and other cancers.
Traditionally, vitamin D was thought to be mostly responsible for bone health and was the medical answer to the rickets phenomenon decades ago. More recent findings have shown that the body has cells and tissues which contain vitamin D receptors necessary for its proper functioning, spurring a lot of interest in the potential of what it can do. The fact that it has just been discovered to prevent a spectrum of chronic diseases, cancer included, has stimulated a debate about whether it is the answer to the cancer problem that has plagued the world.
As early as 2001, the British Journal of Cancer featured a study revealing that cooked and raw fish lowered the risk of lung adenocarcinoma among the Japanese. In a more recent study of Norwegian men and women, consumption of cod liver oil was also found to protect against lung cancer. Fish and cod liver are some of the richest food sources of vitamin D.
What is vitamin D?
Curiously, vitamin D is not a vitamin but a hormone that, as earlier mentioned, affects a lot of physiological processes.
The body needs sufficient sun exposure to produce vitamin D . It can even be stored in the skin until the time when body needs it again. Strangely, it is impossible to get an overdose from sun exposure since the body has a mechanism that controls the amount it needs.
Getting vitamin D from dietary sources may not be enough, as there are not many foods naturally containing vitamin D. This leaves supplementation, which can be an option for those who may not get enough sun exposure.
The recommended intake by the US government is set at 600 IU for children and adults until 70 years of age. Adults above 70 are recommended to take 800 IU a day. A recent study appearing in the Anticancer Research Journal suggests that to be able to take advantage of cancer protection benefits, higher levels are required, or as much as 4,000 to 8,000 IU for adults per day.
Vitamin D controls cancer cells
The likely explanation for this is that vitamin D locally controls genes that help keep cancer at bay by keeping cellular proliferation in check. It has also been suggested that it can induce cell death and regeneration, reducing the potential for malignant cells to survive. Once it has done its job, it initiates its own destruction to guarantee that it does not enter circulation to influence calcium metabolism.
Andreas Moritz, a practitioner of alternative medicine and author of "Cancer is not Disease - It's a Survival Mechanism," describes cancer as the body's healing attempt when all other measures of self-preservation have failed. According to him, the reason the body allows some of its cells to become abnormal is because it attempts to heal itself. Thus, blocking its healing attempt can destroy the body while supporting it in its healing mechanisms can save it.
If Moritz is correct, how we approach cancer may hold a vital clue to its solution. The present treatment of cancer involves procedures such as chemotherapy, invasive procedure and use of pharmaceuticals. This narrow-minded focus on finding a cure practically ignores other options which have been around far longer than conventional medicine - such as the concept of a nutritional cure.
A look at the current trend in cancer treatments has seen such debilitating side effects in a patient's quality of life that it may appear to hasten a patient's decline rather improve his or her health. A patient may as well not undergo chemotherapy, as his chances of surviving without the procedure may well be higher than when he is undergoing treatment.
Nutritional care, on the other hand, seeks to work with the body's needs by providing the necessary vitamins and minerals needed to properly function. It is actually the natural way of keeping the body in balance and the best way to prevent diseases. In the event that the body's system is compromised due to illness, the body's immune system may be strengthened by taking food that naturally boost its immune system.
The alternative option, in the face of emerging research, has supported the idea of nutritional care - an empowered approach to disease that has seen many succumb to the influence of conventional medicine instead. Perhaps, it can now be said that to properly beat cancer, a needle may no longer suffice, and all that it may take is the enjoyment of life with good vitamin D-rich food and a lot of play under the sun.

'Vitamin D Guide' infographic explains importance of vitamin D for optimal health
by Ethan A. Huff, staff writer
(NaturalNews) The vital importance of getting plenty of vitamin D as part of a healthy lifestyle cannot be overstated, and a newly released NaturalNews infographic explains some of the many reasons why vitamin D is crucial to health, as well as how much of it you should be getting.
You can view the infographic here:
http://www.naturalnews.com/Infographic-The-Vitamin-D-Guide.html
Vitamin D can prevent practically every disease known to man
A prohormone, vitamin D is a crucial component of proper development, growth and maintenance of the human body. Without it, the body is prone to develop practically every disease in existence, as vitamin D's metabolic product, 1,25-dihydroxyvitamin D (calcitriol), is responsible for unlocking more than 2,700 binding sites on the human genome (http://www.vitamindcouncil.org/about-vitamin-d/what-is-vitamin-d/).
Vitamin D deficiency, in other words, can lead to high blood pressure, osteoporosis, rickets, depression, diabetes, heart disease, kidney disease, influenza, obesity, hair loss, and cancer. NaturalNews has covered many of the studies over the years that show this to be true, but now this information is available all in one place on the infographic.
Government guidelines for vitamin D are too low
Did you know that the federal government's guidelines for vitamin D intake are far lower than what you really need to stay healthy? The daily dosage of 600 international units (IU) of vitamin D that the government says is adequate for children and adults under the age of 70 is a mere 15 percent of the 4,000 IU daily recommendation given by many nutritionists.
While 600 IU may prevent you from getting rickets, it is not nearly enough to prevent the host of illnesses that are on the rise in modern society today. In fact, the government's recommendations are so low that government advisory boards in recent years have proposed increasing the recommended intake guidelines for vitamin D.
Vitamin D more effective than flu shot at preventing flu
The Vitamin D Guide infographic also points out that vitamin D has been shown to be far more effective than the flu shot at preventing influenza. While a mere one out of every 100 people that take the flu shot are said to avoid the flu as a result, every person that maintains optimal blood levels of vitamin D should be able to avoid the flu.
Be sure to check out the Vitamin D Guide infographic here:
http://www.naturalnews.com/Infographic-The-Vitamin-D-Guide.html
Natural sunlight exposure, vitamin D3 best ways to get vitamin D
The best way for humans to get vitamin D is to regularly expose their skin to natural sunlight. Individuals with fairer skin tones need about 15 minutes of daily sun exposure during the summer months to produce adequate levels of vitamin D in the body. Those with darker skin, depending on the shade, will need as much as an hour and a half of daily sunlight exposure.
During the winter months, it is much more difficult to get enough sunlight exposure, which is why supplementing with vitamin D3 may be necessary. You can also obtain minimal amounts of vitamin D from salmon, sardines, mackerel, shrimp, cod, eggs, fortified cow's milk and fortified yogurt. Raw milk is also said to have high levels of naturally occurring vitamin D.
Be sure to share the Vitamin D Guide with your friends and family so they can learn more about the importance of vitamin D:

Vitamin D, calcium found to save lives among elderly
by Ethan A. Huff, staff writer
(NaturalNews) A new study published in the Journal of Clinical Endocrinology and Metabolism (JCEM) has found that elderly individuals who supplement with both vitamin D and calcium together may have a decreased risk of early mortality. Based on data compiled from eight different randomized controlled trials, researchers found that seniors who supplement with both vitamin D and calcium are about seven percent less likely to die early compared to others.
Dr. Lars Rejnmark, M.D., from Aarhus University in Denmark and his colleagues examined the results of pooled data on more than 70,000 randomized participants with a median age of 70 that participated in vitamin D studies. Some of these participants were instructed to take only vitamin D, while others were instructed to take both vitamin D and calcium. After processing this wealth of data using a stratified Cox regression model, the team discovered that vitamin D can play a powerful role in reducing mortality and increasing life expectancy.
Interestingly, the overall decrease in mortality observed from taking vitamin D with calcium was not the result of vitamin D individuals experiencing fewer fractures, which has been the case in previous studies. There appears to be some other mechanism at play in how the body metabolizes vitamin D alongside calcium that provides other life-extending health benefits.
"This is the largest study ever performed on effects of calcium and vitamin D on mortality," said Rejnmark. "Some studies have suggested calcium (with or without vitamin D) supplements can have adverse effects on cardiovascular health. Although our study does not rule out such effects, we found that calcium with vitamin D supplementation to elderly patients is overall not harmful to survival, and may have beneficial effects on general health."
To gain the most benefits from vitamin D, it is important to also supplement with its various synergistic co-factors, which include magnesium, vitamin K, vitamin A, zinc, and boron. According to the Vitamin D Council, these co-factors are absolutely vital for achieving maximum results from vitamin D, including optimal biosynthesis of this life-giving nutrient. (http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-cofactors/)
"Magnesium has been found to influence the body's utilization of vitamin D in the following ways: Magnesium activates cellular enzymatic activity," says the Vitamin D Council, which emphasizes magnesium as the most important vitamin D co-factor, even though it was not included in the Aarhus study. "Low magnesium has been shown to alter, by way of decreasing, production of vitamin D's active form, 1,25(OH)2D (calcitriol)."

Vitamin D insufficiency promotes chronic disease and increases risk of early death by 50 percent
by John Phillip
(NaturalNews) Medical researchers have been sounding the alarm about the importance of maintaining optimal vitamin D levels from childhood through to the adult years, but millions of aging adults remain grossly deficient in this critical hormone-based nutrient. Vitamin D has demonstrated efficacy in preventing diseases from cancer to cardiovascular disease and dementia. Every cell in the body is now known to have vitamin D receptors where the nutrient provides an essential key to accurate DNA and cellular replication.
A research team from Wake Forest School of Medicine has published the results of an important study on vitamin D and disease risk in the Journal of Clinical Endocrinology and Metabolism (JCEM). The study purports that low levels of vitamin D and high levels of parathyroid hormone are associated with increased mortality in older African American and Caucasian adults. Prior studies on the effects of low vitamin D levels have been conducted on persons of European origin, but this study distinguishes important differences in disease risk between blacks and whites.
Low vitamin D levels are a significant risk factor for disease development and early death
The lead study researcher, Dr. Steven Kritchevsky noted "We observed vitamin D insufficiency (defined as blood levels less than 20 ng/ml), in one third of our study participants. This was associated with nearly a 50 percent increase in the mortality rate in older adults... our findings suggest that low levels of vitamin D may be a substantial public health concern for our nation's older adults." It's important to note that while sun exposure provides a plentiful supply of circulating vitamin D during our younger years, continual warnings to avoid the sun and a natural tendency to produce less of the prohormone from sun exposure as we age, places older adults in a dangerously depleted state.
The study included 2,638 Caucasian and African-American adults, aged 70 to 79. For the baseline reading, participants fasted for 12 hours and blood was drawn and tested to determine levels of vitamin D. Every six months, the study's volunteers were contacted to assess their medical condition. Disease rates were then correlated with vitamin D levels to determine mortality and cause of death. The scientists factored in time of year and degree of sun exposure.
The researchers determined that vitamin D levels under than 30 ng/mL were associated with significantly increased all-cause mortality. Other studies have concluded that even higher vitamin D levels (50 to 70 ng/mL) provided optimal health risk protection. Adults of all ages should have their vitamin D blood saturation checked regularly using the reliable 25(OH)D test, and supplement as necessary to maintain blood levels in the ideal range.
