4 Symptoms of Vitamin B6 Deficiency That Are Often Ignored

3. Tingling and Numbness (Neuropathy)

Vitamin B6 is essential for nerve function, and a deficiency can cause nerve damage over time. Symptoms include:

• The hands and feet are tingly or numb.
• A “pins-and-needles” sensation
• Poor coordination or muscle weakness

Because these symptoms resemble circulatory issues or nerve disorders, many people do not associate them with low B6 levels.

4. Skin Rashes and Cracked Lips

A deficiency in vitamin B6 can cause skin and lip problems, including:

• Itchy, red, and flaky skin (seborrheic dermatitis)
• Cheilitis, or painful fractures in the corners of the mouth
• Dry, chapped lips that don’t heal easily
