Vitamin B deficiency: Symptoms, risks, and dietary sources of B vitamins
B vitamins are essential organic compounds critical for maintaining the body’s homeostatic balance, including metabolic reactions, neurotransmitter synthesis, and tissue repair mechanisms. The B-vitamin complex is particularly vital for regulating nervous system function, thereby supporting psychological stability and cognitive performance. Inadequate intake of these vitamins may lead to neurological dysfunction, impaired concentration, or depressive disorders. Furthermore, B vitamins are indispensable for cellular energy metabolism, bolstering immune responses and maintaining the integrity of skin and mucosal membranes. Given the significant health risks associated with prolonged deficiencies, it is imperative to recognize symptomatic manifestations and identify dietary sources of these micronutrients to prevent deficiencies effectively.
