What is the significance of a pyridoxine deficiency?
Pyridoxine deficiency causes blood, skin, and nerve changes. This vitamin is unique in that either deficiency or excess can cause peripheral neuropathy.
How does pyridoxine deficiency cause anemia?
Low levels of pyridoxine can lead to numbness or tingling in the hands and feet (peripheral neuropathy) and seizures. This vitamin is needed for red blood cells to form. It’s needed for iron to convert into hemoglobin. Low levels of pyridoxine can cause anemia and many other health problems.

What is the function of pyridoxine?
