Vitamin B6 Toxicity: Signs You're Taking Too Much and How to Avoid It
Vitamin B6 Toxicity: Symptoms & Prevention

Understanding Vitamin B6 Toxicity

Vitamin B6, also known as pyridoxine, is essential for brain function, metabolism, and nerve health. However, excessive intake can lead to toxicity, causing serious health issues.

Symptoms of Vitamin B6 Overdose

Taking too much Vitamin B6 can result in:

  • Nerve damage (neuropathy) – Tingling, numbness, or burning sensations in hands and feet.
  • Skin lesions – Rashes or photosensitivity.
  • Digestive issues – Nausea, heartburn, or abdominal pain.
  • Coordination problems – Difficulty walking or maintaining balance.

How Much Is Too Much?

The NHS recommends a daily intake of 1.4mg for men and 1.2mg for women. Exceeding 200mg per day for extended periods can lead to toxicity. High-dose supplements are often the culprit.

Who Is at Risk?

People taking supplements without medical supervision, especially those with certain health conditions, are most vulnerable. Always consult a healthcare professional before starting high-dose B6.

Preventing Vitamin B6 Toxicity

To avoid overdose:

  1. Stick to recommended dietary amounts.
  2. Avoid unnecessary supplements unless prescribed.
  3. Monitor intake from fortified foods.

If symptoms appear, seek medical advice immediately.
