It is known that excessive consumption of pyridoxine/Vitamin B6, regardless of whether it comes from food or supplement sources, can lead to sensory neuropathy.

The Recommended Dietary Allowance for it is 1-2 mg/day and the Tolerable Upper Intake Level (UL) is 100 mg/day for adults. If you are eating supplements which are rich in Vitamin B6 you could be over the UL.
