Vitamin B6 is central to protein metabolism — it helps your dog break down and reassemble amino acids, making it essential whenever protein demands are high (growth, pregnancy, recovery). It also plays key roles in red blood cell production, neurotransmitter synthesis (including serotonin and dopamine), and immune function. Dogs on high-protein diets actually need more B6 because the vitamin is consumed proportionally during protein processing.
A medium banana provides about 0.4mg of vitamin B6 — a medium dog needs approximately 0.4–2.0mg per day. Chicken breast, salmon, sweet potato, turkey, and bananas are all good sources. B6 needs increase with higher protein intake, so dogs on high-protein diets may benefit from B6-rich whole foods alongside their regular meals.
0.0% of daily nutrient intake
Vitamin B6 (Pyridoxine) makes up 0.0% of your dog's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Anemia, skin lesions, poor growth in puppies, reduced immune response, and in severe cases, seizures and neurological dysfunction. Weight loss and reduced appetite may also occur.
B6 is water-soluble and moderate excess is safely excreted. However, chronic extremely high doses of supplemental B6 can cause nerve damage (peripheral neuropathy) — this is a concern with megadose supplements, not food sources.
| Life Stage | Size | Min | Max | Unit | Notes |
|---|---|---|---|---|---|
| Adult | medium 10-25kg | 0.4 | 2 | mg | NRC recommended allowance. B6 needs scale with protein intake — higher protein diets require more B6. |
| Senior | medium 10-25kg | 0.4 | 2 | mg | Senior dogs on higher protein diets for muscle maintenance should ensure adequate B6 to support protein metabolism. |
