Vitamin B6: how much you need & why it matters
Amino-acid metabolism, neurotransmitter synthesis.
How much a day (adults)
| NIH (US) RDA | 1.3-1.7 |
If you don't get enough
Associated deficiency: Vitamin B6 deficiency.
Reported signs of running low:
- Peripheral neuropathy
- Microcytic anemia
- Seborrheic dermatitis
- Seizures
These signs have many causes other than vitamin b6, and several are common in pregnancy anyway. They are a reason to ask for a blood test, not to self-diagnose or start a supplement.
Food sources
- Poultry
- Fish
- Potatoes
- Chickpeas
- Bananas
