Here is the quote (one of many) I found on the internet in a Google search a month ago: " People almost never get too much vitamin B6 from food. But taking high levels of vitamin B6 from supplements for a year or longer can cause severe nerve damage, leading people to lose control of their bodily movements.Feb 17, 2016"
I checked the multivitamin capsule I was taking each morning and discovered it contained 200% ADA of B6. This on top of a vegetarian diet already rich in B vitamins. My numbness in the legs and the uncontrollable muscle spasms in arms and legs had gotten worse after I started taking them. I stopped the vitamin capsules, went on a gluten free diet, and increased exercise to 5 days a week. I met with the Neurologist at Mayo who was not surprised that a lot of my problem had been identified.
