Physiological balance —or homeostasis—refers to the body’s ability to maintain its internal parameters within narrow ranges of optimal functioning, despite constant changes in the environment. Body temperature (37 °C ± 0.5), blood pH (7.35–7.45), blood glucose (0.7–1.1 g/L when fasting), and blood pressure are maintained by continuous negative feedback mechanisms: any deviation triggers a compensatory response. Maintaining this balance constantly engages the autonomic nervous system, the endocrine system (insulin, cortisol, thyroid hormones), the immune system, the kidneys (water and electrolyte balance), and the liver (nutrient metabolism). The quality of this balance depends directly on the intake of essential micronutrients—enzymatic cofactors and second messengers of these regulatory systems—available in vitamin and mineral supplements.
Several factors chronically disrupt homeostasis:
Supporting homeostasis begins with correcting the most common nutritional deficiencies. Magnesium (bisglycinate or malate—300 mg/day) is a cofactor in more than 300 enzymatic reactions involved in energy production, nervous system regulation, muscle contraction, and blood sugar balance. Vitamin D3 (at least 1,000–2,000 IU/day—blood test recommended) regulates more than 200 genes involved in immunity, calcium metabolism, and muscle function. Zinc (10–15 mg/day) acts as a cofactor for more than 300 enzymes and plays a central role in cell repair and the immune response. Electrolytes (sodium, potassium, magnesium) maintain fluid balance and neuromuscular transmission. Omega-3 EPA and DHA (1 to 3 g/day) modulate systemic inflammation and support cell membrane fluidity. Probiotics restore the intestinal barrier and mucosal immunity. Vitamin B12 is essential for cellular methylation, neurotransmitter synthesis, and proper nervous system function. These supplements support homeostasis—any persistent or severe physiological imbalance requires a medical evaluation.
