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
