I take 50mg a day in a bio-available form pyridoxal-5-phosphate. Consider this form instead.
I'm taking it because there is some genetic evidence that I would benefit from doing so. No neuropathies thus far but it's only been about a month and a half.
Blood tests since then have shown that my B6 levels are fine with my usual diet, I don't take multivitamins or supplements anymore.
I don't know much about B6 beyond my own experiences with it, so all I can say is make sure you've discussed it with your GP, and be aware of the coasting effect if you do happen to develop any neuropathic symptoms: https://en.wikipedia.org/wiki/Megavitamin-B6_syndrome
Genetic data is useful to know really, especially for people with MTHFR mutations as many pathways get affected.
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.
