@ray666 Dear Ray, I am not normally on this site, but I feel I must jump in here. Last year I developed symptoms of numbness, loss of balance, mental instability and other symptoms. I went to several doctors and could not find a cause for my symptoms. Finally I saw a Physician (I don't know what it is called in the States - I am writing from Melbourne, Australia, but mean a doctor who speciaizes in diagnoses.) He took an extensive blood test, and it showed that I had 600 TIMES the normal amount of Vitamib B6 in my body. At the time I was only taking one multivitamin capsule a day, but B6 occurs naturally in many foods, and taking the supplement tipped me over into an overdose of Vitamin B6. As soon as I stopped taking vitamins, my symptoms disappeared. So to anyone taking supplements or thinking of taking supplements, please talk to your doctor first. It could be the very supplement(s) you are taking which are causing your symptoms! Don't believe everything you read on the internet about megadoses of supplements. If they eally woked, don't you think every doctor would be recommending them? Stay well, and stay safe. @ellu
