Vitamin K is possibly the least discussed vitamin. It sits off to the side, absent from nutrition panels and with a weird name, so no one ever thinks much about it unless they have a blood clot or rat bait poisoning. But behind the scenes, research has been finding vitamin K is valuable beyond blood clotting, possibly protecting against against cardiovascular disease, dementia, diabetes and osteoporosis.

Australia is one big solar panel but more than one in five of us is vitamin D deficient. Who cares? You should. Let’s find out what vitamin D does - it’s about more than just bones - and how we can be grown ups and meet our vitamin D needs, while looking after our skin.

This one is complex but, by the end, I hope you feel you’ve replaced your chronic low-grade calcium guilt with a plan.
