By “good,” are you asking if they’re safe, or rather, effective?
I’ve consumed expired powdered-form supplements and never gotten sick or had any other adverse reactions.
How were they stored?
Those packets should be airtight & foil lined, but still – cool, dry storage places are preferable in my book.
I know that some medications lose their potency after a while, but the way those powders are processed – and the fact that they’re individually sealed – they may not be effected even in that capacity.
It’s not like a half-used container that’s been opened since the expiration date.
Oftentimes, those dates are simply for stock rotation purposes.
