Four Commonly Ignored Signs of Vitamin B6 Deficiency

3. Tingling, Numbness, or Burning Sensations (Peripheral Neuropathy)

Vitamin B6 is essential for healthy nerve function. A lack of it can damage nerve cells, leading to peripheral neuropathy—a condition that causes tingling, numbness, or burning sensations in the hands and feet.

Why it happens:
Insufficient B6 disrupts the synthesis of myelin, the protective covering of nerves, and neurotransmitters. Weakness or strange feelings are the result of damaged nerves’ inability to transmit messages properly.

How it affects daily life:
This symptom can interfere with walking, typing, or gripping objects. Some individuals also experience muscle cramps or balance problems, which may increase the risk of falls.

What to do:
Restoring Vitamin B6 levels through food or supplements often reduces nerve-related symptoms. Prolonged deficit, however, may result in irreversible nerve damage if treatment is not received.

4. Weakened Immune Function

The immune system relies on Vitamin B6 to produce antibodies and white blood cells that fight infections. Deficiency weakens the body’s defenses, making it more vulnerable to viruses and bacteria.

Why it happens:
The metabolic processes that produce immune cells are supported by vitamin B6.When levels are low, these processes slow down, reducing the body’s ability to respond to infections.

How it shows up:

• Frequent colds or respiratory infections
• Slow recovery from minor illnesses
• General feeling of weakness or being “run down”

What to do:
Consuming foods like poultry, spinach, chickpeas, and fortified grains strengthens immunity. For people with chronic illnesses or poor nutrient absorption, supplementation may be necessary.

Risk Factors for Vitamin B6 Deficiency

Certain groups are more at risk, including:

• People with chronic kidney disease
• Alcohol-dependent individuals
• Pregnant women (due to increased nutritional needs)
• Elderly adults with reduced nutrient absorption
• Individuals on medications such as isoniazid, hydralazine, or penicillamine

Being aware of these risk factors helps in early prevention.

How to Prevent and Treat Vitamin B6 Deficiency

• Eat a balanced diet: Include fish, poultry, starchy vegetables, bananas, and whole grains.
• Avoid excessive alcohol consumption: Alcohol reduces the body’s ability to absorb B6.
• Consider supplementation: Only under a doctor’s guidance, especially for people with medical conditions or restricted diets.
• Regular checkups: Blood tests can confirm B6 levels if deficiency is suspected.

Conclusion

Vitamin B6 may not get as much attention as other vitamins, but it is critical for physical and mental health. Cracked lips, mood changes, nerve issues, and frequent infections are all signals that your body may be running low on this essential nutrient. Unfortunately, these signs are often brushed aside until the deficiency becomes severe.

By paying attention to these symptoms and making dietary adjustments, you can prevent complications and maintain optimal health. If you suspect a deficiency, don’t hesitate to consult a healthcare provider—early detection and treatment are always the best approach.
