Vitamin B6, also known as pyridoxine, is one of the essential B vitamins your body needs to function properly. While it may not receive as much attention as some other nutrients, Vitamin B6 plays a critical role in hundreds of biochemical reactions throughout the body. From supporting brain health and immune function to helping produce red blood cells, this vitamin is necessary for overall wellness.
Unfortunately, many people may not be getting enough Vitamin B6 through their daily diet. When the body becomes deficient in this important nutrient, it can lead to a variety of symptoms and health concerns that can affect quality of life.
What Does Vitamin B6 Do?
Vitamin B6 helps the body:
- Convert food into energy
- Produce neurotransmitters such as serotonin and dopamine
- Support healthy brain function
- Create hemoglobin, the protein that carries oxygen in red blood cells
- Support immune system health
- Help regulate homocysteine levels, which are associated with heart health
- Assist in protein and amino acid metabolism
Because Vitamin B6 is involved in so many bodily processes, even a mild deficiency can create noticeable symptoms.
Signs and Symptoms of Vitamin B6 Deficiency
Fatigue and Low Energy
One of the earliest signs of Vitamin B6 deficiency is feeling tired or lacking energy. Since B6 helps convert carbohydrates, fats, and proteins into usable energy, insufficient levels can leave you feeling sluggish and fatigued.
Mood Changes and Irritability
Vitamin B6 is necessary for the production of important neurotransmitters that regulate mood. Low levels may contribute to symptoms such as:
- Irritability
- Anxiety
- Depression
- Difficulty concentrating
- Brain fog
Some individuals may notice emotional changes before any physical symptoms appear.
Weakened Immune Function
Vitamin B6 plays an important role in maintaining a healthy immune system. Deficiency may reduce the body’s ability to produce antibodies and white blood cells, making it more difficult to fight off infections and illnesses.
If you find yourself frequently catching colds or taking longer to recover from illness, inadequate nutrient intake could be a contributing factor.
Skin Problems

A lack of Vitamin B6 can affect skin health. Some people develop:
- Dry, flaky skin
- Rashes
- Cracks around the mouth
- Inflamed tongue
- Dermatitis-like symptoms
Healthy skin depends on proper nutrient intake, and B6 is one of the vitamins that helps maintain skin integrity.
Numbness and Tingling
Because Vitamin B6 supports nerve function, deficiency can sometimes lead to neurological symptoms such as:
- Tingling in the hands and feet
- Numbness
- Burning sensations
- Difficulty with coordination
Long-term deficiency may contribute to more significant nerve-related concerns.
Anemia
Vitamin B6 is necessary for hemoglobin production. Without enough B6, the body may struggle to produce healthy red blood cells, leading to anemia.
Symptoms of anemia may include:
- Weakness
- Fatigue
- Shortness of breath
- Dizziness
- Pale skin
Since red blood cells carry oxygen throughout the body, reduced production can leave you feeling drained and exhausted.
Cognitive Changes
Vitamin B6 helps support brain health and cognitive function. Low levels have been associated with:
- Memory difficulties
- Mental fog
- Trouble focusing
- Reduced mental clarity
Maintaining adequate B6 intake can help support healthy brain function throughout life.
Who Is at Risk for Vitamin B6 Deficiency?
Certain individuals may have a higher risk of developing a deficiency, including:
- Older adults
- People with kidney disease
- Individuals with digestive disorders
- Those with chronic inflammation
- People who consume excessive alcohol
- Individuals with poor dietary habits
Because modern diets are often lacking in nutrient-dense foods, many people may not consistently get optimal levels of essential vitamins.
Food Sources of Vitamin B6
Vitamin B6 can be found in foods such as:
- Chicken
- Turkey
- Fish
- Potatoes
- Bananas
- Chickpeas
- Sunflower seeds
- Fortified cereals
While eating a balanced diet is important, many people choose to supplement to help fill nutritional gaps and support overall wellness.
