Please note more info on supplement toxicity, especially vitamin B toxicity-- also the dangers of excess Vitamin D and folate. I have nerve damage which may be from, or have been exacerbated by, excess folate and B6. I am going to get most of my vitamins now from food (and sunlight exposure) rather than supplements. See article below. Can You Overdose on Vitamins?
This happened to me also - B6 is a dangerous supplement. I recommend joining the B6 Toxicity FB group to help with healing.
