The brain is the central control organ of our body and requires a variety of nutrients in order to function optimally. These nutrients play an important role in maintaining cognitive function, memory and mental performance. Among the most important nutrients for the brain are omega-3 fatty acids, which are found in oily fish, flaxseed and nuts. Omega-3 fatty acids are crucial for neuronal development, brain signaling and anti-inflammation. The brain also needs vitamins and minerals such as vitamin B12, folic acid, vitamin D, iron and zinc. These nutrients are essential for the production of neurotransmitters, neuronal communication and the regeneration of nerve cells. A balanced diet rich in fruit, vegetables, wholegrain products, healthy fats and lean protein can help to ensure that the brain is supplied with important nutrients. Care should also be taken to ensure adequate fluid intake, as dehydration can have a negative impact on cognitive function. In addition to a healthy diet, it is also important to integrate regular physical activity, sufficient sleep, stress management and mental challenges into everyday life in order to support and improve brain function. The targeted supply of nutrients and care of the entire organism can promote long-term brain health. The vitamins B1, B2, B6, B12, biotin and niacin contained in buckwheat germ powder can contribute to normal nervous system function, pantothenic acid to normal mental performance, folic acid to normal mental function and zinc to normal cognitive function.
