Pyridoxal is a form of vitamin B6, an essential nutrient that plays a crucial role in various bodily functions. It is involved in the metabolism of proteins, carbohydrates, and fats, helping the body convert food into energy. Pyridoxal also supports the production of neurotransmitters, which are chemicals that transmit signals in the brain, contributing to mood regulation and cognitive function. This vitamin is naturally found in foods such as fish, poultry, potatoes, and non-citrus fruits. A deficiency in pyridoxal can lead to symptoms like irritability, depression, and weakened immune function. Ensuring adequate intake through diet or supplements is important for overall health.
