PH012 — Energy Stability Under Variable Conditions
Capacity to maintain energy output when nutritional, physiological, or environmental conditions change.
How steadily energy production holds when conditions around nutrition, physiology, or demand shift.
Therapeutic areas: TA001 ★TA005TA006TA007
Provenance: Core Version 1 registry phenome for energy stability when environmental and physiological conditions change. Near-duplicate review flag with PH013 (RF001) — fuel-substrate specificity reserved for PH013. (origin: BRAIN)

Foundational Evidence
Evidence Confidence: Low–Medium
Registry-level score for this phenome's foundational evidence stack — not Biology → Phenome Confidence on individual mechanism pages.
Metabolic-flexibility reviews strongly anchor the construct; single-FM mechanism linkage in BRAIN v1 — nutrition layer is micronutrient/bioenergetic context rather than condition-variable energy trials.
Registry-level foundational evidence for this phenome. Mechanism pages link to phenome IDs and carry relationship-specific evidence — not duplicated here.
