Wow! Scary stuff! Thank you for posting this.

the term B50 reminds me of the odd circumstance many years ago where an acquaintance took something marketed as B50. In it were high dose B vitamins, several of them occurring as 50 mg or 50 units or whatever it was, including B6 50 mg. B6 at 50 mg. is a high dose for B6, too high for many people. My acquaintance took this pill for two days, then ended up in the ER with seizures. She had not had a seizure before.
Later, I learned that many people cannot metabolize that much B6. I never order a multi-vitamin or B complex which has that high a dose of B6. My present multi-vitamin has 8 mg. of B6.
There is a way to get more B6, that is to take pre-metabolized B6, called sometimes p5p. Most people don't need to do this, but it is available if needed.

Good to know, thanks!
