Folic acid, also known as vitamin B9, plays a crucial role in our body’s mental functions. It is important for the formation of neurotransmitters, which are responsible for the transmission of signals between nerve cells. A deficiency in folic acid can lead to impairment of these processes and have a negative impact on our mental health. Studies have shown that adequate folic acid levels in the body can be associated with improved cognitive function and a lower likelihood of depression. Folic acid may also help to reduce the risk of dementia and Alzheimer’s disease as it helps to maintain the health of nerve cells. It is important to get enough folic acid through a balanced diet, as our bodies cannot produce this vitamin on their own. Foods such as green leafy vegetables, pulses, nuts and seeds are rich in folic acid and can help to support our mental function and mental health. A lack of folic acid can lead to a variety of mental health problems, such as depression, anxiety and memory problems. Studies have shown that a sufficient supply of folic acid can help to improve mood and increase general well-being.
