Agreed. But in the absence of any other authoritative opinion where would you look - common sense and peer reviews aside? Because it seems that we have a lot of folk who have used 'this' or 'that' but nothing really official.....and if you wouldn't trust the FDA would you really trust the manufacturer?
It is a can of worms, I'll grant you. And common sense should prevail, and peer reviews relied upon, but.........
And, as I've done quite a bit of research online and by word of mouth, it seems nobody agrees with each other and they aren't prepared to put their cards on the table and say this is safe or that is safe, except the FDA. For what that's worth.
As Les says probably best to use the manufacturers data sheet. And common sense😀
