Vitamin B6
Vitamin B6 helps enzymes process nutrients and make chemical messengers that nerve cells use to communicate. It helps the body use food; it does not supply calories itself.

Water-soluble vitamin · What does that mean?What it does, and how
Help enzymes process food components
Enzymes carry out chemical reactions in the body. Active forms of vitamin B6 work alongside many of them, especially in reactions that process amino acids, the building blocks of protein.
Coenzyme activity in metabolism · Evidence
Vitamin B6 coenzyme forms support enzyme-mediated metabolism.
Normal physiological role only; does not establish an effect of eating Kale.

Make messengers for nerve cells
Nerve cells communicate using chemical messengers called neurotransmitters. Vitamin B6 helps the enzymes that make some of these messengers, which explains its connection to the brain and nervous system.
Neurotransmitter synthesis · Evidence
Vitamin B6 participates in neurotransmitter biosynthesis.
