CN-001HRV describes variation in the time between heartbeats. It can provide information about autonomic regulation of the heart, but a low value alone does not diagnose disease, nutrient deficiency or biological age.

Read the full article →CN-004IBS is a disorder of gut–brain interaction. Gut sensitivity, bowel movements, food and sometimes a previous intestinal infection can contribute. No single test identifies the cause in everyone with IBS.

Research on immune metabolism raises useful questions, but does not establish one shared cause or treatment for everyone.

The body may compensate by producing more insulin, and blood glucose can rise over time. It is part of a complex metabolic process, not a diagnosis made from one symptom.

Polyphenols such as quercetin and fisetin feature in research, but that does not make supplements containing them an established treatment for ageing. A COMT variant does not provide a validated personalised dose.

Different precursor supplements are being studied, but higher NAD levels are not equivalent to demonstrated improvements in health or lifespan. Links with methylation need interpretation without treating biochemistry alone as clinical proof.
