Established biology
Fundamental processes such as cellular energy metabolism and circadian regulation provide a scientific foundation.
The questionWhat has been demonstrated, in which system, and under which conditions?
A plausible mechanism is a beginning. Reliable clinical knowledge also needs valid measurement, appropriate comparison, reproducible findings and outcomes that matter to people.

These are ways of reading a claim, not evidence ratings for the entire framework.
Fundamental processes such as cellular energy metabolism and circadian regulation provide a scientific foundation.
The questionWhat has been demonstrated, in which system, and under which conditions?
New biomarkers and multi-system models can generate valuable hypotheses. Their usefulness in clinical decisions requires separate validation.
The questionDoes the measure reliably predict or improve a meaningful outcome?
Individualised optimization strategies should be evaluated for benefit, harm, uncertainty and alternatives.
The questionIs there evidence for this intervention in this population, beyond a change in a laboratory result?
Map the evidence. Define testable questions. Evaluate measurement quality. Study outcomes and safety. Publish methods and limitations transparently.
