Vitamin B6, also known as pyridoxine, is essential for brain function, immune support, and metabolism. This article explores the numerous health benefits of Vitamin B6, its rich food sources, and the symptoms of deficiency, highlighting the importance of maintaining adequate levels for overall well-being.

Health Benefits of Vitamin B6 (Pyridoxine)

Improves Mood: Helps produce neurotransmitters like serotonin and dopamine, which regulate mood and reduce depression.
Promotes Brain Health: Supports brain development and function, potentially reducing cognitive decline.
Boosts Immune System: Essential for maintaining a healthy immune system.
Prevents Anemia: Aids in the production of haemoglobin, preventing and treating anaemia.

Supports Skin Health: Helps maintain healthy skin by supporting collagen production

Functions and Roles

Amino Acid Metabolism: PLP is crucial for the metabolism of amino acids, including transamination, deamination, and decarboxylation reactions.
Neurotransmitter Synthesis: It is involved in the synthesis of neurotransmitters such as serotonin, dopamine, and gamma-aminobutyric acid (GABA).
Haemoglobin Production: PLP is essential for the synthesis of heme, a component of haemoglobin.
Glucose Regulation: It helps in the regulation of blood glucose levels by participating in gluconeogenesis and glycogenolysis.

Vitamin B6 is vital for numerous physiological functions, and its deficiency can lead to various health issues, including anaemia, dermatitis, depression, and confusion
