I’ve never used protein powder so i have no idea what it is like…
I do know that zinc lozenges taste very metallic when you are especially deficient in zinc, but mildly metallic when not deficient
I wonder if you are extra sensitive to something in the powder that others do not notice.
Not implying that a chemical aftertaste is ever a good thing or that there is any blame or fault … but that people have a wide range of preferences. For example: cilantro supertasters reporting it as “like soap” (or my wife saying it tastes like the smell of stinkbugs)
idk, just sharing my $0.02 worth of thoughts
