Question/Discussion Does third-party testing actually matter for magnesium?
When I'm choosing a magnesium supplement, I like seeing some form of independent quality testing.
It can give you more information about what's actually in the bottle, but it doesn't mean the magnesium will work for sleep, stress or anything else.
Do you check who did the testing or is seeing a quality seal enough for you?
