And not in a good way, right. While we’ve known about the potential for peripheral neuropathy with excess B6 supplementation since the 1980s, currently there’s a seismic shift in our sense of safety even with previously regarded ‘safe’ levels. You may have heard individual whispers, or the chorus of voices coming together, both here and overseas, belonging to members of the public who report suffering sensory nerve impairment with as little as 2mg/d! Is this a mess of mis-diagnosis, false attribution & nocebo? Perhaps for some, but certainly not for all.
How could this be the case given the many RCTs employing hundreds of mgs per day over months, with no such events recorded?
How could this be given, your (?), certainly my, high dose prescriptions, with only 1 case of quickly reversed, peripheral neuropathy in over 20 years, on my books?
The pieces of this complex paradoxical pyridoxine puzzle are coming to light.
Is it the form?, the dose? the duration? individual differences in B6 metabolism & toxicity threshold? amplification of risk secondary to levels of other nutrients, or the use of certain medications? Yes. And we need to understand each element to better tailor every B6 prescription to the individual & mitigate risk. I have spent the best part of this month reading almost every paper on this from the 1970s to last month and I am now alarmed but more importantly, alert, to what prescription practice changes we can all make to lessen the risk, and control the power of B6. It’s been the most compelling deep-dive. Because in spite of a clear TGA warning issued last year that likely prompted the quiet removal of high dose products from market, it would seem none of the companies have the courage to have this difficult conversation with us 🙁 I invite you to ‘feel the fear & do it anyway’ & listen in to our latest Update in Under 30.
