Vitamin B6, also known as pyridoxine, is an important vitamin that plays a key role in brain function. It helps your body produce neurotransmitters, which are chemicals that transmit signals between nerve cells in the brain. These neurotransmitters affect many aspects of brain function, including mood, memory, and sleep.
In addition to its role in brain function, vitamin B6 also helps your body produce hemoglobin, which carries oxygen in your blood, and can help reduce inflammation in the body. It’s found in a variety of foods, including meat, fish, poultry, bananas, and leafy greens. A deficiency in vitamin B6 can lead to symptoms like fatigue, depression, and memory problems. However, most people in developed countries get enough vitamin B6 through their diet.
