Vitamin B6, also known as pyridoxine, is an essential nutrient that is involved in numerous processes within the body. As a coenzyme, it plays a vital role in the metabolism of carbohydrates, proteins, and fats, converting them into usable energy. Vitamin B6 also supports brain development and function, contributing to cognitive processes such as memory, mood regulation, and neurotransmitter synthesis. Additionally, this vitamin is involved in the production of haemoglobin, the protein responsible for carrying oxygen in the blood. By supporting the immune system, Vitamin B6 helps maintain a strong defence against infections and promotes overall well-being.
