You're going to go. Hello and welcome to a very warm and sunny Friday 5 as I sit here in my South

London studios. What a glorious spot of weather we're having across most of the UK right now.

I do hope it is happy and sunny wherever you are and wherever you are listening.

Now of

shown to potentially play such an important part

in supporting our immune system,

never more so important than it is now. important

around the world have also been shown to have some of the lowest levels

of vitamin D. So there does appear to be a powerful correlation. And as you probably know, there

are actually two forms of vitamin D

there's ergo calciferal which is

vitamin D2

and cole calciferal if I've said that correctly, which is Vitamin D3. And during the summer when we are hopefully

getting some sunlight on our skin, our vitamin D levels are naturally higher, but at other times we especially need to make sure that we are getting plenty in our diets, especially if you are a plant-based eater, as vitamin D is only found in relatively small numbers of foods, mostly animal origin such as oily

fish, red meat, liver, especially and egg yolks.

Now it's also added as a synthetic supplement to things like packet breakfast

cereals and the British government suggests that we take a supplement to give us

around 10 micrograms a day and not to go above a hundred micrograms. So, Vitamin D3 comes from animal produce, as I said, mostly meat and

oily fish. And Vitamin D2, interestingly, comes from some plant-based food supplements and also from mushrooms

that have been grown in direct sunlight or put onto a window sill, so they create D3 before we eat them. Now D2
