Can Vitamin D Deficiency in Children Affect the Severity of Illnesses?
Jan 15, 2018

A recently published systematic review and meta-analysis assesses the prevalence of vitamin D deficiency in children admitted to the pediatric intensive care unit. 

Vitamin D is a regulator of calcium levels in the body. A deficiency in vitamin D levels correlates with many skeletal conditions and has been identified as a cause of conditions such as hypocalcaemia, an electrolyte imbalance characterized by low levels of calcium in the blood. The deficiency affects the pathology of the brain, cardiovascular system, respiratory system, and immune system. Due to the vital role of these systems in critical illnesses, a vitamin D deficiency in children can have a significant impact on the treatment and onset of several diseases.

A Canadian review study published by Critical Care compared the vitamin D status of patients in the pediatric intensive care unit (PICU) with the vitamin D status of healthy individuals of the same age. The study also assessed the contribution of vitamin D deficiency in children towards increased critical illness and mortality.

Reduced sunlight may contribute to winter weight gain
Jan 10, 2018

We may have a new reason, in addition to vitamin D generation, to bask in a little sunshine.

A breakthrough study by University of Alberta researchers has shown the fat cells that lie just beneath our skin shrink when exposed to the blue light emitted by the sun.

“When the sun’s blue light wavelengths—the light we can see with our eye—penetrate our skin and reach the fat cells just beneath, lipid droplets reduce in size and are released out of the cell. In other words, our cells don’t store as much fat,” said Peter Light, senior author of the study, who is a professor of pharmacology and the director of the U of A’s Alberta Diabetes Institute.

“If you flip our findings around, the insufficient sunlight exposure we get eight months of the year living in a northern climate may be promoting fat storage and contributing to the typical weight gain some of us have over winter,” added the Dr. Charles A. Allard Chair in Diabetes Research.

High doses of vitamin D rapidly reduce arterial stiffness
Jan 02, 2018

In just four months, high-doses of vitamin D reduce arterial stiffness in young, overweight/obese, vitamin-deficient, but otherwise still healthy African-Americans, researchers say.

Rigid artery walls are an independent predictor of cardiovascular- related disease and death and D deficiency appears to be a contributor, says Dr. Yanbin Dong, geneticist and cardiologist at the Georgia Prevention Institute at the Medical College of Georgia at Augusta University.

So researchers looked at baseline and again 16 weeks later in 70 African-Americans ages 13-45 - all of whom had some degree of arterial stiffness - taking varying doses of the vitamin best known for its role in bone health.

In what appears to be the first randomized trial of its kind, they found that arterial stiffness was improved by vitamin D supplementation in a dose-response manner in this population, they write in the journal PLOS ONE.

Overweight/obese blacks are at increased risk for vitamin D deficiency because darker skin absorbs less sunlight - the skin makes vitamin D in response to sun exposure - and fat tends to sequester vitamin D for no apparent purpose, says Dong, the study's corresponding author.

Low vitamin D, muscle injuries linked in NFL prospects
Dec 21, 2017

NFL prospects with low levels of vitamin D are more likely to get serious muscle injuries, according to a study published Thursday.

The study examined 214 college football players from the 2015 NFL Scouting Combine, an annual showcase where players perform for talent scouts. It found statistically significant differences in muscle injuries, with the rate increasing with the severity of the vitamin D deficiency.

 It also found a racial disparity, with low levels of vitamin D in 70 percent of the 167 black athletes surveyed. In the 47 white or Polynesian athletes, just 13 percent had low levels. Lighter-skinned people can produce more vitamin D simply by exposing their skin to the sun.

While the study doesn’t prove cause and effect, the correlation is strong enough that it should be investigated further, said Dr. Brian Rebolledo, a Scripps Clinic orthopedic surgeon who helped lead the research.

Could a Vitamin D3 Supplement Affect Heart Failure Outcomes?
Dec 18, 2017

 A recent study examines if a high-dose vitamin D3 supplement could replenish vitamin D stores in deficient heart failure patients.

 Roughly 600,000 Canadians currently live with heart failure and 50,000 new cases are diagnosed each year. The cost of the disease burden amounts to $2.8 billion annually.1 Prognosis is generally poor with an average one-year mortality rate of 33%.2 Numerous studies indicate that a vitamin D deficiency in patients with heart failure can significantly increase the risk of morbidity and mortality, including from sudden cardiac death.3,4

Adequate clinical data on the effects of a vitamin D3 supplement in heart failure patients are not available, especially on quality of life (QOL) indices and exercise cardiopulmonary status (CPX). Both the QOL index and CPX are good prognostic markers of mortality and morbidity in heart failure patients. A recent study attempted to monitor the effects of a vitamin D3 supplement on these markers in heart failure patients. The results of the study were published in a recent issue of BMC Cardiovascular Disorders.5

Vitamin D levels linked to better brain health
Dec 18, 2017

FORGET brain training, crosswords and puzzles — improving your mind could be as simple as getting a daily dose of sunlight.

Melbourne University researchers have found older women who have adequate vitamin D levels have better attention, cognitive flexibility and working memory.

Dr Alicia Goodwill studied 252 participants aged 55-67 from the Women’s Healthy Ageing Project to investigate the association between midlife vitamin D and cognition in Australian women.

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?

Canadian Study Finds Tanning Salon Sunbeds Effective for Raising Vitamin D Levels

NEWS RELEASE
For Immediate Distribution

TORONTO, Ont (November 15, 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.”

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.”
