@lynnn Late last year I suffered various mysterious neurological, symptoms, and a clever docyor I consulted (I had already consulted without success) ran a blood test and discovered that my Vitamin B6 levels were 600 times normal. All I was taking at the time was 1 daily multivitamin supplement. Read the labels on the food you buy. Many, many common foods such as breakfast cereals, bread, all sorts of procesed foods have added B6. By the time you add up how much B6 you are getting from your food alone, it might be ridiculous to think of even taking a multivitamin which could push you over the limit. My doctor's advice - throw away all those supplements , if you are eating a normal Western diet you are very unliely to be defficient in any vitamin or mineral. If you fel you could do with something extra, then make an appointment with your doctor, have your blood levels tested, and stop wasting money and damaging your health by self-prescribing or believing all you read on the internet. It might interest you to know that here in Australia, the Government has just taken all Vitamin B6 supplements off pharmacy shelves. Please look after yourself...
