Study confirms vitamin D protection against cold and flu
Dec 11, 2017

A new global collaborative study has confirmed that vitamin D supplementation can help protect against acute respiratory infections.

The study, a participant data meta-analysis of 25 randomized controlled trials including more than 11,000 participants, has been published online in The BMJ.

“Most people understand that vitamin D is critical for bone and muscle health,” said Carlos Camargo, MD, DrPH, of the Department of Emergency Medicine at Massachusetts General Hospital (MGH) and the study’s senior author.

Low Vitamin D Levels at Birth Linked to Higher Autism Risk
Nov 29, 2017

Summary: Researchers have identified a link between low levels of vitamin D at birth and an increased risk of a child being diagnosed on the autism spectrum by the age of three.

Source: Wiley.

Low vitamin D levels at birth were associated with an increased risk of autism spectrum disorders (ASDs) at the age of 3 years, researchers report in a recent Journal of Bone and Mineral Research study.

In the study of 27,940 newborns in China, 310 were diagnosed with ASDs at 3 years of age, with a prevalence of 1.11 percent. When the 310 children with ASDs were compared with 1,240 control subjects, the risk of ASDs was significantly increased in each of the three lower quartiles of vitamin D level at birth, when compared with the highest quartile: an increased risk of ASDs by 260 percent in the lowest quartile, 150 percent in the second quartile, and 90 percent in the third quartile.

“Neonatal vitamin D status was significantly associated with the risk of ASDs and intellectual disability,” said senior author Dr. Yuan-Lin Zheng.

Vitamin D may help prevent rheumatoid arthritis, suggests study
Nov 21, 2017

Maintaining sufficient vitamin D levels may help to prevent rheumatoid arthritis, according to researchers.

A study led by the University of Birmingham compared the ability of immune cells in blood from inflamed joints in people with rheumatoid arthritis to respond to the so-called sunshine vitamin.

The experts found tissue that was not diseased responded well to vitamin D, suggesting it could be effective at preventing the onset of rheumatoid arthritis, which affects more than 400,000 people in the UK.

The vitamin proved much less effective once the disorder was established, suggesting much higher doses may be needed in combination with other anti-inflammatories such as steroids.

The study’s co-author, Prof Martin Hewison, said the results had significant implications for people in the UK.

Study Finds Tanning Salon Sunbeds Effective for Raising Vitamin D Levels
Nov 16, 2017

Sunbeds with a UVB component similar to solar summer sunshine may provide an effective alternate vitamin D source during winter months, according to a new Canadian study just published in the journal Dermato Endocrinology. 

 
People who use tanning salons, specifically sunbeds that have UVB during the winter reach physiological blood levels (>100 nmol/L) of vitamin D, the study reported. It found 
that participants who used typical sunbeds emitting UVB rays in the range equivalent to outdoor summer sunshine increased their vitamin D blood levels on average by 42 nmol/L. This was achieved using standard tanning exposure schedules on salon sunbeds.
 
“Sunbeds enable exposure to nearly 100% of skin in a controlled manner which amplifies their effectiveness for vitamin D production,” said Dr. Samantha Kimball, lead author and research director at Pure North S’Energy Foundation in Calgary, AB. “We found that you can effectively raise your vitamin D levels into the desired range without burning and following Health Canada’s recommendations. But there are risks to any type of UV exposure, whether from the sun or sunbed.”

Research into link between vitamin D and schizophrenia wins medal
Nov 15, 2017

Research into brain development and schizophrenia has led to international acclaim for The University of Queensland’s Professor John McGrath, recipient of Denmark’s Strömgren Medal.

Queensland Brain Institute researcher and Director of the Queensland Centre for Mental Health Research’s Professor McGrath studies the epidemiology of schizophrenia – searching for the causes, effects and patterns of the illness.

Professor McGrath and his team demonstrated low vitamin D status in pregnant women and babies could affect brain development and increase risk of schizophrenia later in life.

Professor McGrath’s 2016 appointment to the Niels Bohr Professorship Program in Aarhus, Denmark established an international program of psychiatric epidemiology, which included a project to investigate the link between schizophrenia and vitamin D levels in 80,000 newborns.

Professor McGrath will deliver the medal’s accompanying Erik Strömgren Lecture. 

“It will be an opportunity to reflect on many years of vitamin D research, done in close collaboration with my colleagues in Denmark,” said Professor McGrath.

Vitamin D may be simple treatment to enhance burn healing
Nov 06, 2017

Patients with severe burns who have higher levels of vitamin D recover more successfully than those with lower levels, according to a study presented at the Society for Endocrinology annual conference in Harrogate. This study is the first to investigate the role of vitamin D in recovery from burn injury and suggests that vitamin D supplementation may be a simple and cost-effective treatment to enhance burn healing.

Despite improvements in burn care over the last 10 years, many patients are still at risk of poor recovery. Complications can range from delayed wound healing through to infections. Patients with severe burns are at high risk of infection that may lead to life-threatening sepsis. Vitamin D is known to have antibacterial actions that may help combat infection and therefore aid in wound healing of burn patients.

In order to investigate the role of vitamin D in recovery from burn injuries, Professor Janet Lord and Dr Khaled Al-Tarrah, at the Institute of Inflammation & Aging in Birmingham, assessed the recovery progress, over one year, in patients with severe burns and correlated this with their vitamin D levels. The study found that patients with higher levels of vitamin D had a better prognosis, with improved wound healing, fewer complications and less scarring. The data also showed that burns patients tend to have lower levels of vitamin D. These data suggest that vitamin D supplementation immediately following burn injury may have potent health benefits to the patient, including enhanced antimicrobial activity to prevent infection, and improved wound healing.

Canadian Winter How can I get enough vitamin D?
Nov 10, 2017

By Perry Holman, Executive Director, Vitamin D Society

Canadians’ vitamin D levels drop substantially in winter due to the lack of UVB in the sun at our northern latitude at this time of year. For November Vitamin D Awareness month, the Vitamin D Society has released a new short video to help people develop a vitamin D winter action plan.

First, let’s understand why a great number of Canadians are vitamin D deficient. Until about 100 years ago, people spent a large amount of their time outdoors. Now most of us work indoors and increasingly spend our leisure time inside, drawn to the Internet, TV, video games and other passive forms of recreation. When we are outdoors, many of us follow health warnings to protect ourselves from UV exposure with sunscreen, clothing and shade.

The result is that Canadians’ vitamin D levels have fallen by 13% in just six years. Approximately 14 million Canadians — 38% of the population — do not meet Health Canada guidelines for vitamin D levels of 50 nmol/L. This puts them at a higher risk for serious diseases such as osteoporosis, diabetes, multiple sclerosis, cancer and cardiovascular disease.

But it gets worse. The vitamin D level recommended by Health Canada is only half the level recommended by a large number of vitamin D experts. Forty eight scientists, doctors and researchers have recommended that everyone reach a 25(OH)D blood level of between 100-150 nmol/L. And nearly all of us, 93% of us in fact, are below these optimal vitamin D levels.

If you are not taking vitamin D daily - then it may not be working
Aug 03, 2017

by Carole Baggerly, Director at GrassrootsHealth

Today I have decided to get all the exercise I will need this month. So, I am going to get up, head to the gym and do 15 different sessions of cardio interspersed with 15 different sessions of my weight machines. Then, I will take a yoga class to round out the day. 

Ridiculous - right?

Are People Really Taking Sky-High Doses of Vitamin D?
Jul 11, 2017

By Perry Holman, Executive Director, Vitamin D Society

A new study1 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. Also vitamin D supplement use of ≥4000 IU per day increased from 0.2% in 2007 to 3.2% in 2014.

The researchers made this key point in their discussion:

“Overall, 3% of the population exceeded the tolerable upper limit of 4000 IU daily, and may be at risk of adverse effects as a consequence”

But how many people were really supplementing over 4000 IU/d? If they were just taking 4000 IU/d there would be no risk as this is the safe upper limit and does not require doctor supervision.

Vitamin D Day calls attention to World Health Crisis

NEWS RELEASE
For Immediate Distribution

TORONTO, Ont (October 26, 2017) – Canadians’ vitamin D levels continue to plummet, according to the latest report from Statistics Canada. Vitamin D levels for Canadians, aged six to 79, have dropped by 13% in the last six years and show no signs of improvement. Fourteen million Canadians do not meet Health Canada’s vitamin D blood level requirements of 50 nmol/L. This figure rises to 15 million —40 per cent of us — during winter months.

The Vitamin D Society has proclaimed November as Vitamin D Awareness month since 2009 and is working with the Vitamin D Council from the US to celebrate Vitamin D Day on November 2nd. Vitamin D Day is a day for Canadians to learn about the importance of vitamin D for good health and to take action to ensure that they have optimal vitamin D blood levels.

Dr. Gerry Schwalfenberg, an Assistant Clinical Professor at the University of Alberta who also has a clinical patient practice, has published numerous papers calling attention to this disturbing vitamin D deficiency problem.

“I see patients’ vitamin D levels start to drop at this time of the year when sunlight does not contain sufficient UVB to make vitamin D in your skin,” he says. “Without immediate corrective action through supplementation or artificial UVB exposure, these people will be vitamin D deficient until next summer or longer if they avoid the sun. This leads to a higher risk of many diseases such as cancer, heart disease, osteoporosis, diabetes, multiple sclerosis and also infections such as colds and flu.”
