Vitamin D News
Every cell in your body needs Vitamin D and because it’s so important I like to make sure that I am up to date with the latest Vitamin D news.
It is common knowledge that vitamin D plays an important role in helping the body to absorb calcium and in bone mineralisation.
However accumulating scientific evidence is proving that vitamin D provides more Health benefits than simply bone health.
Vitamin D deficiencies can occur when exposure to sunlight is limited or as the body ages the ability to produce vitamin D is impaired.
USANA’s Vitamin D supplement is formulated with maximum strength to help you achieve an adequate level of vitamin D in one tablet.
A landmark study out this year (2016) in PLOS ONE found that women over 55 with blood concentrations of vitamin D higher than 40ng/ml, had a 67% lower risk of cancer compared women with levels lower than 20ng/ml.
“We have quantitated the ability of adequate amounts of vitamin D to prevent all types of invasive cancer combined, which had been terra incognita until publication, of this paper,” said Cedric Garland, researcher and adjunct professor at the UC San Diego School of Medicine Department of Family Medicine and Public Health.

The researchers concluded that optimal levels for cancer prevention are between 40 and 60ng/ml, and that most cancers occur in people with vitamin D blood levels between 10 and 40ng/ml.
The study did not reveal whether supplementation or sun exposure was the best way to obtain vitamin D. However, the researchers concluded that vitamin D only starts protecting against cancer once you get you blood level up to 40 ng/ml. They noted that more Health benefits were observed at even higher levels.

Vitamin D supplements may help people with diseased hearts, a study suggests.
A trial on 163 heart failure patients found supplements of the vitamin, which is made in the skin when exposed to sunlight, improved their hearts’ ability to pump blood around the body.
The Leeds Teaching Hospitals team, who presented at a meeting of the American College of Cardiology, described the results as “stunning”.
The British Heart Foundation called for longer trials to assess the pills.
Vitamin D is vital for healthy bones and teeth and may have important Health benefits throughout the body but many people are deficient.
The average age of people in the study was 70 and, like many people that age, they had low levels of vitamin D even in summer.
“They do spend less time outside, but the skin’s ability to manufacture vitamin D also gets less effective [with age] and we don’t really understand why that is,” said consultant cardiologist Dr Klaus Witte.
Patients were given either a 100 microgram vitamin D tablet or a sugar pill placebo each day for a year.
And researchers measured the impact on heart failure – a condition in which the heart becomes too weak to pump blood properly.
The key measure was the ejection fraction, the amount of blood pumped out of the chambers of the heart with each beat.
In a healthy adult, the figure is between 60% and 70%, but only a quarter of the blood in the heart was being successfully pumped out in the heart failure patients.
But in those taking the vitamin pills, the ejection fraction increased from 26% to 34%.
Dr Witte told the BBC News website: “It’s quite a big deal, that’s as big as you’d expect from other more expensive treatments that we use, it’s a stunning effect.
“It’s as cheap as chips, has no side effects and a stunning improvement on people already on optimal medical therapy, it is the first time anyone has shown something like this in the last 15 years.”
The study also showed the patients’ hearts became smaller – a suggestion they are becoming more powerful and efficient.
