Vitamin B6 is centrally involved in amino acid metabolism, which makes it particularly important for cats given their high protein requirements. It serves as a coenzyme in over 100 enzymatic reactions, most of which involve protein and amino acid processing. B6 also supports red blood cell formation, neurotransmitter synthesis (affecting mood and brain function), and immune system regulation. Because cats metabolize significantly more protein than most pets, their B6 requirements are proportionally higher.
A small serving of cooked chicken breast (about 30g) provides roughly 0.15–0.2mg of vitamin B6 — your adult cat needs approximately 0.2–0.8mg per day, comfortably supplied by any meat-based diet or commercial cat food.
0.0% of daily nutrient intake
Vitamin B6 (Pyridoxine) makes up 0.0% of your cat's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Loss of appetite, weight loss, anemia, skin lesions, kidney damage (oxalate crystal formation), convulsions, and stunted growth in kittens. Deficiency is uncommon in cats eating meat-based diets.
Very high doses of supplemental B6 over extended periods can cause nerve damage (peripheral neuropathy) with signs including unsteady gait and loss of sensation in the paws. This is only a concern with excessive supplementation, not dietary intake.
| Life Stage | Size | Min | Max | Unit | Notes |
|---|---|---|---|---|---|
| Adult | — | 0.2 | 0.8 | mg | B6 requirements increase with protein intake. Since cats eat high-protein diets, their B6 needs are proportionally higher than many other pets. |
| Juvenile | — | 0.25 | 1 | mg | Growing kittens need B6 for protein metabolism and neurotransmitter synthesis during rapid development. |

B vitamins work synergistically in energy metabolism and nervous system function. Thiamine and B6 in particular both support nerve health and amino acid processing, and adequate levels of both are needed for optimal function.
What this means: Meat-based diets naturally provide a full complement of B vitamins, so individual B vitamin deficiencies are uncommon in cats eating commercial food. The exception is thiamine, which can be destroyed by raw fish (thiaminase) or excessive heat during food processing. If your cat shows neurological signs, check thiamine status first.
