That’s a placebo affect. Most generics are stuff that don’t meet the standards of the name brand, but is still fine to sell. Kind of a form of downcycling.
I don’t know that placebo is the right word (or if you just pulled that info out of your ass) but even if it was, if people consume the generic and just feel like it was the same, then who cares? It’s not like people are buying Kirkland chemotherapy, it’s some cookies or lotion or whatever, and our feelings about those things are totally subjective anyway.
There’s way WAY too many generic and store brands for them all to just be QC rejects.
They’re not. I have celiac, and I’ve learned from reading labels that they often have completely different ingredients/manufacturing conditions.
They’re not QC rejects, but they’re also not the same thing repackaged.
It depends, especially with medication it’s the same thing due to regulations.
Usually it is just cheaper ingredients but made in the same factory, and branded with a different label.
