Origin of vitamin and mineral mix

Hello, while a bit has already been talked about origins of the ingredients like the oats I wondered if something can be said about the origins of the vitamins and minerals. Are these processed from certain plants and which are these?

Or is this even unknown to Jimmy Joy itself because only the final minerals and vitamins are bought?

It’s interesting the don’t answer this because I can’t find a answer for that and where the oat and soy comes from
