Five Writers. Five Pillars. One Evidence Standard.

Alyssa covers clinical biomarkers and preventive health diagnostics. Her writing focuses on translating peer-reviewed biomarker research into actionable intelligence — what to test, what the numbers mean, and what the longevity targets look like compared to standard clinical ranges.

• ApoB and cardiovascular particle count
• Fasting insulin and metabolic early warning
• hsCRP and chronic inflammation
• Longevity vs clinical reference ranges

Rachel covers evidence-based longevity interventions — the named protocols with documented effects on biological aging markers. Her writing breaks down exactly what to do, for how long, and what the research says about expected outcomes.

• Zone 2 training and VO2 max
• Time-restricted eating protocols
• Cold exposure and sauna evidence
• Protocol periodisation and sequencing

Olivia covers the intersection of stress physiology, brain health, and cognitive longevity. Her focus is the cortisol-hippocampus relationship, BDNF, and the evidence base for interventions that protect or restore cognitive function over time.

• Cortisol and hippocampal cell renewal
• Sleep deprivation and cognitive decline
• BDNF and neuroplasticity
• MBSR and stress intervention evidence

Lorena covers insulin resistance, glucose variability, and the metabolic markers most people never track. Her writing connects metabolic dysfunction to biological aging — making visible the damage that standard blood panels miss entirely.

• Insulin resistance and early detection
• Ultra-processed food and metabolic impact
• Glucose variability and cellular aging
• Metabolic flexibility and mitochondrial function

Savannah covers sleep architecture, HRV, and parasympathetic recovery. Her position: if your recovery system is broken, every other protocol you are running produces a fraction of its expected return. Recovery is not rest — it is a measurable biological process.

• Sleep architecture — SWS, REM, light sleep
• HRV as a recovery readiness signal
• Glymphatic system and waste clearance
• The four sleep architecture killers
