There unfortunately isn’t enough organic cheese made in the UK to have a large enough supply of whey to make whey protein with it. You need very large quantities of whey to produce whey protein, as the filtration systems have to filter out such tiny things such as lactose from the whey and therefore the equipment is very expensive and can only be carried out on a very large scale. This is why we have organic whey from the UK combined with organic whey from a few other European countries such as Germany and France.
