Vitamin B6
B-Complex vitamins are essential for functioning of the nervous system. However, excessive consumption can lead to paradoxical neurotoxicity, resulting in irreversible sensory neuropathy.

Vitamin B6 Toxicity

What caregivers know about vitamin B6 toxicity has risen to the level of an urban legend in many cases. The scientific literature does not help much. The claims of the amount required and the amount of time needed for developing toxicity vary greatly from one peer-reviewed article to the next. Having found very little guidance in the general scientific literature, we turned to the National Institute of Health (NIH) for vitamin B6 toxicity information.

The NIH states that the amount of time for the lowest daily dose of vitamin B6 administration to display side effects from excessive vitamin B6 is one gram per day for 12 months. The minimum dosing value cited here represents a total dose of 365 grams of vitamin B6 spread out over a 12 month period. The NIH also notes that severity of symptoms appear to be dose dependent and stopping the vitamin B6 usually stops the symptoms.

Under this protocol, there is no exposure of patients to the NIH established minimum vitamin B6 levels intake associated with side effects.
