Have you looked up what foods have a high level of vitamin B6? Perhaps you have been consuming foods with a high level of B6. I do know that bananas have a high B6 level. You also might want to do some research on the Mayo Clinic website and other medical websites besides Google to discover if there is anything other than food that has B6 in it.

Also, how do you feel? If you feel good and normal perhaps that's just the way your body is and you needn't worry about it. After all, we are all different especially when it comes to physical aspects of our bodies.

I hope you get some answers!
