B6 (pyridoxine) is a water-soluble vitamin that plays a crucial role in various bodily functions. It is essential for the metabolism of proteins, carbohydrates, and fats, helping the body convert food into energy. Additionally, B6 is important for the production of neurotransmitters, which are chemicals that transmit signals in the brain. This vitamin can be found in a variety of foods, including poultry, fish, potatoes, chickpeas, bananas, and fortified cereals. A deficiency in B6 can lead to symptoms such as anemia, skin disorders, and neurological issues. Maintaining adequate levels of B6 is vital for overall health.
