Final answer:
Dietary supplements can help reduce anxiety by correcting nutrient deficiencies important for brain function and mood regulation, complementing a balanced diet.
Step-by-step explanation:
Dietary supplements may help reduce anxiety by addressing nutrient deficiencies that affect brain function and mood regulation. A balanced diet ensures the provision of essential nutrients and vitamins and minerals that support the maintenance of proper bodily functions, including good health and reproductive capability. It is important to note that supplements are not meant to provide instant relief, replace regular meals, or stimulate the nervous system. Instead, they complement the diet to ensure the nervous system, which includes the parasympathetic and sympathetic systems, can properly regulate the processing of information and behavior control.
