Is country life one of the crappy brands?
No, it’s decent. I liked Solgar until they were bought out by P&G at which point I stopped recommending them. My favorites are Jarrow, Doctor’s Best and Life Extension. A little more spendy, but worth the price. If you want magnesium there’s only one brand to bother with and that is KAL’s magnesium glycinate. Unless you want magnesium-l-threonate for brain support.
