> Why the main media/government channels don’t talk about this more is baffling and potentially criminal. Maybe because there’s no money to be made from Vitamin D because there are no patents?

Or perhaps the supplies would run empty if this became big news (?)

Vitamin D is extremely cheap, so I assume it is very easy to manufacture. It's also freely available in a lot of different stores. So I doubt there would really be a shortage.

Additional data point: In Belgium, it's encouraged to give your children daily Vitamin D supplements until the age of 6. That tells me that there is scientific consensus about the safety, and that there is a large supply of it.

Wouldn't that be a good thing for supplement manufacturers? They can charge more due to the scarcity.

It's definitely getting out there anyway, in my local Boots the entire vit D section was empty, still a few bottles of the more expensive versions left (e.g. gluten free versions).

Yes, but supplement manufacturers can't make health claims.
