Performance Substrate Assessment

Meaning

Performance Substrate Assessment is the clinical evaluation of the body’s available molecular resources that directly fuel physical and cognitive activity and recovery. This comprehensive analysis extends beyond simple glucose measurement to include circulating levels of essential amino acids, fatty acids, key vitamins, and cofactors required for ATP production and neurotransmitter synthesis. Optimizing these substrates is a prerequisite for sustained energy, mental clarity, and efficient muscle repair. This assessment provides the tangible biochemical data needed for precision nutritional and metabolic intervention.
