> Excess B12 is really bad. Neuropathy.

Do you have any source for this? I can find some "it-might-be-bad" studies through a quick googling, but in general the idea seem to be that excess B12 is thought to be unproblematic ("it's just peed out").

B6 not B12. My bad.

Can confirm, overdosing on Vitamin B6 is bad. Lots of very scary symptoms.

I accidentally poisoned myself with B6 from Magnesium tablets over the course of a year: https://davids.town/vitamin-b6-overdose (my levels were 38x the healthy range).

tl;dr: Always check your Magnesium for what else the tablet includes. If it contains Pyridoxine hydrochloride (i.e. Vitamin B6) or another Pyridoxine compound, find one that doesn't. Since then, Swisse is the only brand I've found that consistently sells "pure" Magnesium tablets here in Australia.

Both of those have od risk around daily of 250 mg B6, 250 mcg B12, I believe.
