The Best Time to Take Vitamin D for Maximum Absorption, According to Health Experts
Mar 27, 2024
When it comes to the supplement aisle, multivitamins, omega-3s and probiotics might score more shelf real estate. However, if that multi doesn’t come with a dose of vitamin D, your doctor might recommend adding another pill to your routine.
Roxana Ehsani, M.S., RD, CSSD, a Miami-based board-certified sports dietitian, explains that vitamin D is one of four fat-soluble vitamins (A, E and K are the others). It’s also a hormone our body creates after being exposed to the sun, playing “many important roles in our body,” adds Ehsani. These include supporting your immune system, muscle and nerve function, your body’s ability to absorb calcium and more.

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.
