Biomarkers & optimal ranges
Learn the key biomarkers across metabolic, hormonal, and cognitive health — what each one measures, what the optimal range is, and what drives it in either direction.
Your biology is measurable. Your biomarkers are trackable. The research on what actually moves them — blood glucose variability, GrimAge, BDNF, NAD⁺, cortisol patterns, muscle protein synthesis — is accessible, if you know where to look and how to read it. Lontreau.edu is built around that science.

Lontreau.edu is built on one premise: that the science of longevity is genuinely useful to people who are willing to engage with it seriously.
Pro gives you full access to every programme, course, challenge, community space, and research resource on the platform — organised by biological system, not by trend.
A structured starting point — built on the science of how your key biological systems interact. FORWARD covers the foundational frameworks of health optimisation: how metabolic function, hormonal signalling, gut health, and cognitive biology connect, and what the evidence says about the interventions that actually move the needle.

Establish your baseline. Review your current blood work, body composition data, and health history against the FORWARD framework.
Use the FORWARD protocols and reference library to build a plan around your specific markers — not a generic template.
Work through structured protocols, track your inputs, and use Short Protocols and Extended Programmes to drive specific outcomes.
Return to your biomarkers. Compare against baseline. Adjust the plan based on what the data shows — not how you feel.
Learn the key biomarkers across metabolic, hormonal, and cognitive health — what each one measures, what the optimal range is, and what drives it in either direction.
Each update covers a specific development in the science — drawn from primary literature and translated into precise, accessible language. Direct about what the evidence supports.
A structured self-assessment framework using your own blood work and DEXA biomarkers. Understand where you sit relative to optimal ranges — not just reference ranges.
One membership. Complete access. Every programme, course, challenge, research resource, and community space — organised by biological system, not by trend.

Structured research library — organised by biological system, not by trend
Live sessions with longevity experts — recorded for members
Each course takes a single domain and uncovers what is happening at the cellular and systems level, what the primary research shows, and how that translates into protocol. Built for people who want to understand the science well enough to make genuinely informed decisions.
Two of the most powerful systems shaping how you age aren't human at all — they're microbial. The gut and oral microbiomes are living ecosystems that influence digestion, immunity, hormones, and inflammation — the very foundations of your healthspan. Learn how these microbial networks act as master regulators of your biology, affecting everything from energy and metabolism to cardiovascular and cognitive health.
The hormonal transition of peri-menopause and menopause is one of the most significant biological shifts a woman will experience — and one of the most misunderstood. This course covers the mechanisms behind oestrogen, progesterone, and testosterone decline, their downstream effects on metabolic health, bone density, cognition, and cardiovascular risk, and the evidence-based interventions that actually move the needle.
Your genome is not your destiny — but it is a detailed instruction manual. This course will cover how to read your genetic data in the context of longevity, understand SNPs that influence metabolic function, inflammation, detoxification, and cognitive resilience, and translate that information into personalised protocol decisions.

Real-time data on how your body responds to food, sleep, stress and movement.
Blood glucose is one of the most powerful and measurable levers in longevity. This challenge uses a Continuous Glucose Monitor (CGM) to give you real-time data on how your body responds to food, sleep, stress, and movement — and teaches you to interpret that data the way a functional medicine clinician would. Normal ranges are not optimal ranges. This is where that distinction becomes personal.
What you will learnLab reference ranges are built for disease detection, not performance. Learn the difference between a 'normal' fasting glucose and an optimal one — and why that gap matters for your biological age, energy, and long-term metabolic health.
Understand fasting glucose, post-meal spikes, time-in-range, glucose variability, and what each pattern tells you about your metabolic flexibility, insulin sensitivity, and inflammation risk.
Apply the science directly: which foods blunt glucose spikes, how a 10-minute walk after eating changes your curve, how poor sleep raises your fasting glucose, and how to build a metabolic environment that supports longevity.
Challenge included with membership. The Blood Sugar Optimisation with CGM Challenge is available immediately when you join, along with every other protocol, programme and resource in the library. The CGM device itself is purchased separately.
Start 90 days freeLonger-duration programmes focused on the core systems of healthspan: metabolic function, muscle preservation, cognitive performance, and stress physiology. Structured tracking, evidence-based protocols, and defined outcome markers throughout.
Take control of your energy, focus, and metabolic health. Using CGMs, food tracking, and lifestyle devices, uncover patterns in your glucose responses and learn how your habits impact your metabolism.
Unlock your body's natural GLP-1 potential. Optimise appetite, blood sugar, and metabolic health through evidence-based strategies targeting your gut lining, microbiome, diet, and daily rhythms.
Evidence-based tactics that support cellular repair, reduce inflammation, optimise metabolism, and improve hormonal balance — with measurable improvements in biological age as the outcome.

Longevity medicine is not a single intervention — it is a systems approach. Every programme and course on Lontreau.edu is built around the domains that the evidence consistently shows to be the primary drivers of healthspan. Genetics is part of the picture, but it is one input among many.
