A new study echoes findings of previous research, indicating that taking vitamin D supplements does not provide some of the purported health benefits, but a report on the research from The Times clarifies the resounding point: sunlight, not supplements, is the answer.
However, Vieth isn’t offering a free pass to become a vampire. There may not be a physiological difference between vitamin D3 sources, but the evidence makes a powerful case for continuing to source it from sunshine — if not for the vitamin, then for many other good things.
“Sunlight provides benefits that are not mediated via vitamin D,” he writes, such as improved blood pressure, mood, and life expectancy. He points to a 2016 prospective longitudinal study from the Journal of Internal Medicine that looked at sun exposure habits and causes of death in more than 29,500 Swedish women over 20 years. continue reading

“Laughably low recommendations” for vitamin D intake prevent forward progress in solving the vitamin D deficiency epidemic and reducing the associated adverse health conditions
Key Points
Prevalence of vitamin D deficiency is common – a 2018 study found that vitamin D deficiency and insufficiency are increasing at a global level – it is and has been a pandemic
Severe vitamin D deficiency, defined as less than 12 ng/ml, dramatically increases the risk of excess mortality, infections, and many other diseases, and should be avoided whenever possible
Another study found that higher levels of vitamin D were linked to a 59% lower risk of developing Alzheimer’s Disease
Academic who showed chemical sunscreens harm coral reefs suspects they also contribute to beach erosion by poisoning plants that stabilise sand dunes
Chemical sunscreens have ingredients that can stress corals and leave them more susceptible to disease and death, according to research published in 2015
Now the researcher who headed that study is investigating whether they may also harm plants holding sand dunes together, and thus contribute to beach erosion
A US researcher is investigating whether the chemical sunscreens he showed damage corals are also toxic to plants on sand dunes and thus contribute to the erosion of beaches.
Salon owners – it's time to join forces and make a mark in the tanning industry. To maintain and develop a prosperous indoor tanning industry in Canada by educating Canadians on how to maximize the benefits while minimizing the manageable risks of responsible UV exposure. We will pursue continuous improvement of the perception of tanning amongst Canadians through scientific facts and research that support indoor tanning as an intelligent, controlled choice for UV exposure.
