Sounds like a boring and not-relevant-for-most topic but it was a surprisingly interesting and relevant-for-many conversation. Did you know that some widely-used magnesium supplements contain up to forty times (40X) the RDI (recommended daily intake) of vitamin B6? Even more ridiculous when you consider that most people don't even know these products contain any B6 because they're actually trying to supplement their magnesium! And what are the potential consequences of overdosing on B6? Oh, only muscle weakness, nerve damage, numbness, tingling, nausea, loss of balance, peripheral pain, vision damage and more. Guess who just checked and (subsequently) chucked his magnesium tabs in the bin?
