I have mostly disavowed other areas of investigation. But this I am still following. Very complex issue, but based on the experiences of many that B6 toxicity is very common and continues to affect users well after blood levels return to normal. Also proposes a protocol for removing B6 from muscles where it does its damage. All info at this website seems well researched and you can get all of the information FREE. It’s a tough protocol to follow, but many on the site have claimed recovery. So here I am. I have taken B vitamin supplements in the past but don’t now and don’t know whether B6 was ever elevated. But it’s a chance.
