The Claim
Some individuals believe that Vitamin B6 is completely safe at any dose because it is a water-soluble vitamin and excess is excreted.
Origin
This misconception is based on the general understanding that water-soluble vitamins are less likely to cause toxicity compared to fat-soluble ones.
What Science Says
While it's true that Vitamin B6 is water-soluble, high doses over time can lead to nerve damage and sensory neuropathy. Case reports and RCTs have documented adverse effects at intakes over 200 mg per day. The tolerable upper intake level is set to prevent such outcomes.
Verdict
False
