Sadly the article doesn't say how much Vitamin D we need, but given many of us report improvements in our well being after finding we need Vitamin D3 supplements to boost our Vitamin D into the normal range, I though this article would be of interest. There is obviously a great deal more we need to learn about the role of Vitamin D in our bodies!
"Professor Elina Hypponen has spent more than a decade examining the short and long-term health effects of vitamin D. Arriving in Adelaide recently from University College London in the United Kingdom, Prof Hypponen is now based at UniSA’s School of Population Health.
“The reason there are such wide-ranging health effects is that these vitamin D receptors are present throughout the body – they’re in most vital organs, they’re in different types of immune cells, they’re in your gut. If the receptor for a hormone exists in certain parts of the body, then you really need to start thinking about what it’s doing there." (Emphasis mine - Neil)
While much research has been done into the effects of low vitamin D status, Prof Hypponen is now turning her attention to the other end of spectrum – what happens when the body has high levels of vitamin D. Prof Hypponen says there is an emerging body of research that suggests high levels of vitamin D isn’t always a good thing.
“There is an expectation that higher vitamin D status is always better and that it will always lead to beneficial health outcomes but we are beginning to think that theory might not always hold true,” she says."
“That’s where I would like to take my work next – I’d like to see if we can obtain evidence about when we move to the higher end of the vitamin D status scale to see whether there is any evidence to suggest potential adverse effects. I’d like to find out how high is it safe to go.”

I recently saw this Dusky Moorhenbuilding a nest on a fallen branch in the middle of a nearby waterway while ignoring the passing traffic. When I checked back yesterday, she was sitting on the nest and wouldn't budge for some of my sandwich. We've just had the driest November in 17 years and some recent hot days have resulted in the water level falling so low that the nest is no longer surrounded by water. We had some rain today - hopefully enough to replenish the water and dissuade children and marauding cats from interfering.
