System Buffer Capacity

Meaning

System Buffer Capacity is a physiological metric representing the total reserve and adaptive range a biological system possesses to absorb and effectively neutralize stressors, whether metabolic, physical, or psychological, without progressing into a state of functional failure or disease. In the context of hormonal health, this capacity is largely governed by the integrity and reserve of the adrenal, thyroid, and gonadal axes, as well as the efficiency of the body’s detoxification and antioxidant systems. A high buffer capacity signifies robust resilience and a reduced allostatic load, allowing the individual to maintain peak performance even under significant stress.
