Vitamin B6 Food Sources: Everyday Foods and Dietary Needs

Vitamin B6 is found in a wide range of everyday foods. It contributes to normal protein metabolism, red-blood-cell formation and nervous-system function. For most people, the first step is to eat a varied diet—not to seek high-dose supplements. This guide focuses on food sources and dietary requirements. For supplement risks, see our separate vitamin B6 supplement safety guide.

What is vitamin B6?

Vitamin B6 is the collective name for related compounds, including pyridoxine and pyridoxal. It is a water-soluble vitamin involved in many enzyme reactions. Adequate intake supports normal body functions; this does not mean that taking extra B6 above your needs improves memory, energy or mood.

Everyday food sources of vitamin B6

Chicken and turkey: practical protein sources that also contribute B6.
Fish: salmon and tuna can contribute meaningful amounts.
Chickpeas and other legumes: useful plant-based options.
Potatoes: a familiar food that contains B6.
Bananas: contribute a smaller amount as part of a varied diet.
Fortified cereals: amounts vary by brand; check the nutrition information.

Different foods provide different nutrients, so variety matters more than relying on one ingredient. Food composition changes with portion size and preparation. For a detailed list of food amounts, consult the NIH Office of Dietary Supplements' vitamin B6 fact sheet.

How much vitamin B6 do you need?

Dietary requirements depend on age and life stage. As an example, the NIH recommends approximately 1.3 mg per day for adults aged 19–50, with different recommendations for older adults, pregnancy and breastfeeding. These figures describe total dietary intake, not a suggested supplement dose. Australian advice should be interpreted using relevant local nutrient reference values and individual circumstances.

If you are concerned about a restricted diet, poor absorption or a medical condition, a GP or accredited practising dietitian can assess whether additional support is needed. Do not diagnose a deficiency based on tiredness alone.

Does more vitamin B6 mean better nerve health?

No. Vitamin B6 is necessary for normal nerve function, but excess vitamin B6 from supplements can damage nerves. The TGA warns that peripheral neuropathy can occur with supplementary B6, including in some people taking multiple products and at doses below 50 mg daily. Symptoms may include tingling, burning or numbness of the hands and feet.

Normal dietary intake from food is not associated with this risk. If you experience such symptoms while taking supplements containing B6, stop those supplements and seek medical advice promptly. See our complete B6 supplement safety and label-checking guide for the different ingredient names and Australian regulatory warnings.

When might a supplement be appropriate?

Most people can obtain adequate B6 from food. A health professional may recommend supplementation when there is a diagnosed deficiency or a specific clinical need. Before buying any B-complex or multivitamin, check whether it duplicates B6 already present in other supplements, including magnesium or zinc products.

Never treat a large percentage on a label as proof that the product is more effective. If you are considering PURITYFIC Active Multi B Complex, review its current label with a pharmacist to decide whether it is appropriate for your circumstances.
