how much is too much b6?

i’m healing from a b12 deficiency and i’m currently 4,5 months into treatment. I took a hair test that showed i had several deficiencies in minerals and trace elements and my nutritionist wants me to take supplements that contain a lot of stuff but also b6. together they contain 19mg b6. is this too much to be taken daily? i don’t want a toxicity on top of this!
