Functions:

Amino Acid Metabolism: Vitamin B6 is a coenzyme involved in the metabolism of amino acids and the synthesis of neurotransmitters.

Cognitive Development: It plays a role in cognitive development by contributing to the production of neurotransmitters that regulate mood and sleep.

Immune Function: Vitamin B6 supports immune function and hemoglobin production.

Deficiency:

Vitamin B6 deficiency can lead to anemia, dermatitis, depression, confusion, and a weakened immune system. It is more common in individuals with kidney disease or autoimmune disorders.
