Vitamin D toxicity rare in people who take supplements, researchers report
Apr 30, 2015

Americans have low vitamin D levels, research shows, and as a result, vitamin D supplement use has climbed in recent years. Vitamin D has been shown to boost bone health and it may play a role in preventing diabetes, cancer, cardiovascular disease and other illnesses. In light of the increased use of vitamin D supplements, researchers set out to learn more about the health of those with high vitamin D levels. They found that toxic levels are actually rare.

Pancreatic cancer risk linked to weak sunlight
Apr 30, 2015

UC San Diego epidemiologists suggest harm may come from low vitamin D

Writing in the April 30 online issue of the Journal of Steroid Biochemistry and Molecular Biology, researchers at University of California San Diego School of Medicine report pancreatic cancer rates are highest in countries with the least amount of sunlight. Low sunlight levels were due to a combination of heavy cloud cover and high latitude.

"If you're living at a high latitude or in a place with a lot of heavy cloud cover, you can't make vitamin D most of the year, which results in a higher-than-normal risk of getting pancreatic cancer," said first author Cedric F. Garland, DrPH, adjunct professor in the Department of Family Medicine and Public Health and member of UC San Diego Moores Cancer Center.

Reviewing Role of Vitamin D in Endocrine Disorders
Apr 27, 2015

It may be time for endocrinologists to rethink vitamin D levels in their patients, according to some experts. With research challenging the recommended daily intake of vitamin D as well as studies on the role vitamin D plays in inflammation and disease prevention, clinicians have a great deal to consider.

In a study published in the journal Cell Reports, for instance, researchers report that inactivation of the vitamin D receptor induced diabetes and atherosclerosis in animal models.1

Researchers found that inactivating the vitamin D receptor on monocytes and macrophages promoted inflammation of the liver and in artery walls. It also increased the ability of monocytes in the blood to adhere and migrate into blood vessel walls.

6 things you should know about vitamin D
Apr 27, 2015

Figuring out all the factors that can affect your vitamin D level is complicated. Your body makes vitamin D when sunlight hits the skin. You can also get the vitamin from food (mainly because it’s been added; few foods are natural sources of vitamin D) or by taking a supplement.

The process by which the body makes vitamin D is complex. It starts when the skin absorbs rays in the invisible ultraviolet B (UVB) part of the light spectrum. The liver and the kidneys also participate to make a form of the vitamin that the body can use.

A number of factors influence a person’s vitamin D levels. Here are six important ones.

Why So Gloomy? In Sun-Deprived China, Only 5% Have Healthy Levels of Vitamin D
Apr 24, 2015

Earlier this week, I found out I have a Vitamin D deficiency. A resident of Beijing, I only recently tried to figure out what was going on after symptoms of fatigue and mild depression led me to the doctor, who ordered a series of blood tests. He told me I was among a number of expats who become Vitamin D deficient after moving here. We deduced that the lack of sunshine from the pollution cover and the fact that I stay inside more often because of air quality issues led to my deficiency.

Luckily, the fix is easy: my doctor prescribed a large dose of daily Vitamin D supplements. But it made me wonder how, after only a year and a half of living in China, Beijing’s poor air quality has already affected my health.

Vitamin D Deficient Follicular Lymphoma Patients Experience Higher Relapse Risk
Apr 23, 2015

Low vitamin D levels prior to treatment may be linked to risk of relapse or death for patients with follicular lymphoma (FL), according to a new study published online in the Journal of Clinical Oncology.

“Our data, replicated internationally, support other published observations linking vitamin D deficiency with inferior cancer outcomes,” said Jonathan W. Friedberg, MD, co-leader of the study, in a statement. Friedberg is director of the Wilmot Cancer Institute at the University of Rochester Medical Center.

Spring Sunshine Welcomed as Canadians Vitamin D Levels Plummet

Risk increased for a number of serious diseases

WOODSTOCK, Ont. (March 19, 2015) – A new Statistics Canada report has confirmed that 12 million Canadians have vitamin D blood levels that are below what Health Canada recommends and vitamin D levels continue to drop from previous years.

Results from the 2012 to 2013 Canadian Health Measures Survey (CHMS), released December 2014, report that 35% or 12 million Canadians have vitamin D blood levels below the Health Canada guideline of 50 nmol/L. This has increased by 3% from the previous Statistics Canada report (2009-2011) of 32%. The mean average vitamin D level for Canadians age 6-79 years has also dropped by 9.9% over the last 4 years from 68 nmol/L to 61 nmol/L. “This downward trend in vitamin D blood levels is putting more Canadians at a higher risk for many cancers including colon, breast and prostate, as well as for cardiovascular disease, diabetes, multiple sclerosis, osteoporosis and other serious diseases” stated Perry Holman, Executive Director of the Vitamin D Society.

Building consensus on optimal vitamin D levels in Canada

Key disease organizations support effort to curb vitamin D deficiency

TORONTO, Ont. (November 21, 2014) - A push to develop a Canadian Vitamin D Consesus that can be used to educate Canadians on the importance of optimal vitamin D levels for health is gaining support.

Vitamin D experts from around the world attended a workshop in Toronto earlier this month with the goal of reducing vitamin D deficiency in Canada.

A number of prominent Canadian disease organizations, including the Multiple Sclerosis Society of Canada, Osteoporosis Canada, the Canadan Breast Cancer Foundation and Prostate Cancer Canada attended the November 4 workshop on vitamin D.

"It's extemely encouraging to see momentum building behind efforts to improve education among Canadians on how to ensure they are getting enough vitamin D. Together, we can help people improve their health and reduce risk to several serious diseases," said workshop chairperson Dr. Reinhold Vieth, retired director of the Bone and Mineral Laboratory at Mount Sinai Hospital and a professor at the University of Toronto in the Department of Laboratory Medicine and Pathobiolgy.

Shining a light on need to boost vitamin D levels in Canada

Vitamin D Society workshop on Nov. 4 to build consensus on curbing vitamin D deficiency

TORONTO, Ont. (October 31, 2014) – As winter draws closer and our daylight hours grow shorter, Canadians are being urged to take steps to protect their health by maintaining sufficient levels of vitamin D.

To mark Vitamin D Awareness Month in November, The Vitamin D Society is spreading the word about the importance of proper vitamin D levels and the affect it has on our everyday health.

On Tuesday, November 4 in Toronto the non-profit organization is hosting the Vitamin D Consensus Workshop, featuring several international medical experts. Representatives from key disease organizations have been invited to attend to help develop a Canadian Vitamin D Consensus that can be used to educate Canadians on the importance of optimal vitamin D levels for health. The workshop comes shortly after World Vitamin D Day on November 2.

“Due to Canada’s northern latitude, Canadians cannot get sufficient levels of vitamin D through sunshine from November to May,” said workshop presenter Dr. Reinhold Vieth, retired director of the Bone and Mineral Laboratory at Mount Sinai Hospital and a professor at the University of Toronto in the Department of Laboratory Medicine and Pathobiology. “Low levels of vitamin D can create a higher risk of serious diseases, such as cancer, cardiovascular disease, diabetes, multiple sclerosis, osteoporosis and others.”
