Frequently Asked Questions

Can vitamin B6 cause nerve damage?

Yes. Taking more than 100 mg/day of vitamin B6 for months or years can cause peripheral neuropathy — numbness, tingling, and pain in hands and feet. This is reversible if caught early. The UL is 100 mg/day, but most people only need 1.3-1.7 mg/day.
