Yes, I’ve been avoiding anything from China that you put in your body, as much as I possibly can. Food of course, but it’s really hard to avoid supplement ingredients, because the vast majority of supplement brands source from China. There are a handful that don’t or at least test them frequently. Vegetable protein powders, say pea, almost all from China or processed in China. Medication, if you take a variety of meds, you pretty much can’t avoid it, sadly.
But, while China is by far the worst, it’s not like other places are trustworthy. And it’s not a new phenomenon. It’s as old as human society. Why do you think the FDA and regulatory agencies had to be created in the first place. Extensive fraud of every kind. Wherever there’s money to be made. Go read some history. It’s everywhere and as far back as you care to look. Adulterated flour, oils, jams, anything and everything. Medication - almost all of it was either useless or actively harmful, yes, the famous “snake oil” was an actual phenomenon.
People love to complain about “excessive regulation” and the FDA, but I’ll take that every time over the alternative. You can’t change human nature. You can only regulate it as best you can.
