What vitamin B6 does
B6 helps more than 100 enzymes, mostly in protein metabolism. It’s needed to make haemoglobin and neurotransmitters like serotonin.
How much
Adults need about 1.3–1.7 mg a day.
Plant sources
Chickpeas, bananas, potatoes, avocado, sweet potatoes, pistachios, sunflower seeds, lentils and whole grains.
How many portions of each food would cover a day's Vitamin B6?
A note
Long-term high-dose B6 supplements can damage nerves. Foods won’t — stick to food sources unless your doctor advises otherwise.
