In sunny Australia, why are so many people vitamin D deficient?
Mar 18, 2024

In summer, Australia has one of the highest UV indexes in the world. So, it may be surprising to learn that about one in four of us are deficient in vitamin D.

At least 80 per cent of a person’s vitamin D intake comes through sun exposure, as the skin absorbs and converts UVB radiation. 

“We have surprisingly high levels of vitamin D deficiency considering our climate,” said Professor Rebecca Mason, a bone and skin researcher at the University of Sydney. She attributes the trend to both efforts to protect the skin from melanoma and lifestyle factors.

“Not everybody has an opportunity to be outside in the sun,” she said. “If you’re not well or mobile, you tend not to get outside. Office workers are inside for most of the day. And there are quite a few people in the community who wear covering clothing for modesty and custom.”

New concept explains link between vitamin D and ageing
Mar 18, 2024

by Agnieszka Libudzka
How does vitamin D protect against the most common diseases and at the same time promote healthy ageing? The key to explaining the mechanism may be linking the body's individual response to vitamin D with immunocompetence (potent immunity).
"The results of our research suggest that immunocompetence describes not only an individual's ability to resist pathogens and parasites, but also to fight non-communicable diseases and the aging process itself," says Professor Carsten Carlberg from the Institute of Animal Reproduction and Food Research at the Polish Academy of Sciences (PAS) in Olsztyn, a biochemist who specializes in vitamin D research.

Vitamin D: Canadian’s Overcoming Deficiency
Mar 14, 2024

Vitamin D deficiency is indeed a common issue in Canada and in other countries located at higher latitudes, where sun exposure can be limited, especially during the colder months. Vitamin D is crucial for bone health, immune function, and has been linked to mood regulation among other health benefits. The body primarily produces vitamin D through skin exposure to sunlight, specifically UVB rays. In locations like Canada, the angle of the sun during the fall and winter months significantly reduces the production of vitamin D, contributing to the prevalence of deficiency.

World Glaucoma Day: Is there a link between Vitamin D deficiency and glaucoma?
Mar 12, 2024

Glaucoma, a group of eye diseases, is generally the result of pressure on the eyes. It damages the optic nerve responsible for transmitting visual information. Age is one of the risk factors for glaucoma, but over the years, researchers have also found a link between vitamin D deficiency and glaucoma. Vitamin D is mostly known for contributing in bone health. But can vitamin D also help in treating glaucoma? On World Glaucoma Day, we tell you the connection between vitamin D and glaucoma.

Individuals in the United States Are Not Achieving Optimal Vitamin D Levels
Feb 29, 2024

Researchers found that current vitamin D dosing recommendations are not helping individuals achieve optimal vitamin D levels, thus putting them at risk of experiencing a cardiac event, according to a randomized trial.1

According to the study, low vitamin D levels are associated with increased risk of cardiovascular events, such as heart attack or stroke. Further, the prevalence of vitamin D deficiency—defined as less than or equal to 20 ng/mL—in the United States is estimated at 40%. Currently, the recommended dietary allowance of vitamin D in the US is 600 to 800 IU.

Using the randomized event-driven trial, Target-D, the researchers sought to provide an overview of dosing and titration for individuals to achieve vitamin D serum levels greater than 40 ng/mL.

Could Scots be more at risk of dementia… because of a lack of SUNSHINE?
Feb 20, 2024

Scots may be at a far higher risk of dementia because of their low levels of vitamin D, according to new research.

Experts are calling on ministers to review their guidance on the vitamin in a bid to fight the illness, which is Britain’s biggest killer and costs the country £2billion a year.

The study shows that people deficient in the sunshine vitamin have a 58 per cent greater chance of dementia.

UV→D NOW - Why a supplement does not replace sunlight!
Mar 03, 2022

By Perry Holman, Executive Director, Vitamin D Society

Key Points:

  • No supplement will replace all the benefits of sunlight when considering the full spectrum of light
  • UVB exposure on your skin from sunlight makes Vitamin D naturally without ever going to toxic levels
  • Most people know about the benefits of vitamin D for bone health. Vitamin D also has benefits for the immune system, cardiovascular health, autoimmune diseases such as diabetes, and multiple sclerosis, skin, and has been linked to lower incidence of many forms of cancer
  • UVA exposure releases nitric oxide stores in your skin, helping reduce your blood pressure and improving cardiovascular health
  • Visible light is beneficial for skin, sleep, happiness and relaxation
  • Infrared light is a powerful antioxidant beneficial for intercellular melatonin used by the mitochondria to repair cell damage
  • When sunlight is unavailable or not strong enough, turn to surrogates such as sunbeds, phototherapy units or light boxes
  • Overexposure to sunlight has risks too. The key is to know your skin and take care not to burn. Moderation!

UV→D NOW Let the Sunshine back into your life!
Nov 18, 2021

By Perry Holman, Executive Director, Vitamin D Society

How did we get to this point in our relationship with the sun? If you follow the current health recommendations from some dermatologists you would live in perpetual darkness, in a bunker, and never let the sunshine hit your unprotected skin. Sunscreen use is advised to be applied to your skin everyday of the year regardless of the whether you are indoors or not. Regardless of your skin type. This action has unforeseen consequences that I hope to shine a light on for you.

For November, Vitamin D Awareness Month, we are focusing on educating people to the many benefits of sun and UV exposure. This is why we have named it UVD NOW. Because getting UV exposure is important for vitamin D, nitric oxide and so many other photoproducts for your health. The lack of sun exposure is the main root cause of vitamin D deficiency, and studies have found that people with low vitamin D are at a higher risk of many serious diseases such as cardiovascular disease, major cancers such as breast and colorectal, autoimmune diseases such as diabetes and multiple sclerosis and even infections, flus, colds and much more.

Over 100 Scientists, Doctors, & Leading Authorities Call For Increased Vitamin D Use To Combat COVID-19
Dec 10, 2020

By Dr. Karl Pfleger, PhD AI & Computer Science, Stanford University

To all governments, public health officials, doctors, and healthcare workers,

Scientific evidence indicates vitamin D reduces infections & deaths.

Research shows low vitamin D levels almost certainly promote COVID-19 infections, hospitalizations, and deaths. Given its safety, we call for immediate widespread increased vitamin D intakes.

Vitamin D modulates thousands of genes and many aspects of immune function, both innate and adaptive. The scientific evidence1 shows that:

  • Higher vitamin D blood levels are associated with lower rates of SARS-CoV-2 infection.
  • Higher D levels are associated with lower risk of a severe case (hospitalization, ICU, or death).
  • Intervention studies (including RCTs) indicate that vitamin D can be a very effective treatment.
  • Many papers reveal several biological mechanisms by which vitamin D influences COVID-19.
  • Causal inference modeling, Hill’s criteria, the intervention studies & the biological mechanisms indicate that vitamin D’s influence on COVID-19 is very likely causal, not just correlation.

Vitamin D Deficiency and COVID-19

“For weeks and weeks people from ethnic minority communities have been wanting to know how they can better protect themselves from coronavirus.” [BBC News June 13th 2020] We believe that during Covid-19, ethnic minority communities in the UK, the USA and elsewhere, and all others vulnerable to seasonal Vitamin D deficiency, have been seriously let down by politicians and medical-scientific officialdom. As a result they have been needlessly deprived of extensive biological knowledge that would have protected them against disease and death from a novel virus, for which adequate levels of Vitamin D are essential.
