Depletions

Vitamin B6 (Pyridoxine)

Symptoms of vitamin B ₆ deficiency may include weakness, nervousness, insomnia, mental confusion, irritability, and anemia. Long-term low levels of this nutrient may also increase the risk of heart disease as well as colon and prostate cancers.

Editorial Note

The selected depletions information presented here identifies some of the nutrients that may be depleted by certain medications. The signs and symptoms associated with nutrient deficiency may also indicate conditions other than nutrient deficiency. If you are experiencing any of the signs or symptoms mentioned, it does not necessarily mean that you are nutrient deficient. Nutrient depletion depends upon a number of factors, including your medical history, diet, and lifestyle as well as the length of time you have been taking the medication. Please consult your healthcare provider; he or she can best assess and address your individual healthcare needs, and determine if you are at risk for nutrient depletions from these medications as well as others not listed here.
