| Functions |
- Works with B12 and Folate in Methylation reactions
- Brain and nerve function: transports amino acids into brain for use in making neurotransmitters; converts tryptophan to serotonin
- Involved in:
- Gluconeogenesis
- Formation of body proteins and structural compounds: chemical transmitters in nervous system, red blood cells, prostaglandins
- Maintaining hormonal balance and proper immune function

| Sources notes |
Best sources yeast, wheat germ, sunflower seeds, whole-beans, banana, avocado |
| Vegetable Sources |
kale; spinach; turnip greens; peppers; potatoes |

- Suspicions that food colorings, medications, and excessive protein and alcohol intake are antagonizing B6 use in body
- Active form pyridoxal 5′ phosphate (PLP) made in liver from food: Zinc needed for this
- Zinc, Vitamin B2 and Magnesium needed at target sites for function
- Very heat stable
|
| Deficiency factors |
- Brain and nerve function: deficiency causes abnormal brain wave patterns and decrease in nervous system activity and impaired nerve function
- Depression; convulsions; glucose intolerance
|
| Toxicity |
Can be toxic, leading to neuropathy, sensorial neuropathy and impaired detoxification reactions |
