Is this difficult to make? At £10-20 a kg I might like to take a stab at it
Edit £40 a kg according to amazon

I'm not sure if it's really a viable option to make it at home from beer trub. This is from Wikipedia:
Nutritional yeast is produced by culturing a yeast in a nutrient medium for several days. The primary ingredient in the growth medium is glucose, often from either sugarcane or beet molasses. When the yeast is ready, it is deactivated with heat and then harvested, washed, dried and packaged. The species of yeast used is often a strain of Saccharomyces cerevisiae. The strains are cultured and selected for desirable characteristics and often exhibit a different phenotype from strains of S. cerevisiae used in baking and brewing.

Ok BUT cultivate yeast in glucose = brew
not sure what washing and drying means or if Saccharomyces cerevisiae is a brewing yeast

Washing is literally what it says on the tin. Taking whatever the medium is (in this case glucose) off and washing the yeast with fresh distilled water. It stops it from fermenting anyfirther.
Kveik (a type of Scandinavian beer yeast) go through this process.

the more I research the less viable this becomes... I would need a chem lab

Most brewing strains are s. cerevisiae but not all s. cerevisiae are brewing strains. As that quote said, the selected strains are often different from brewers strains, but I don't know why.

You're probably right but anything that comes fortified (B12 normally), my first thought is "cheap as chips" manufactured processed garbageProbably hence the price.
