I ran out of my usual B complex, so checked online for similar from a well known maker which is stocked by my local pharmacy. I was surprised to see that for each of their 3 B complex products they give the following warning:
"Long term intake of this amount of vitamin B6 may lead to mild tingling and numbness"
The amounts of B6 were either 25 or 50 micrograms daily (correction it's mgs).
My thoughts are that we take these regularly and don't think about or know about side effects like this.
Checking the NHS website for B6 I find "Don't take more than 10mg of vitamin B6 a day in supplements unless advised to by a doctor."
Any thoughts?
