How It Works
Four steps from curiosity to clarity — use our tools, learn from the data, and make better health decisions.
Assess Where You Stand
Start with our free health tools — symptom checkers, risk calculators, and a comprehensive metabolic health assessment. In 5 minutes, you'll have a clear picture of your metabolic, hormonal, and recovery risk factors.
No account required, no payment, no sales pitch. Just data about your health.
Available tools
- Metabolic Health Score Calculator
- Insulin Resistance Risk Assessment
- Hormone Symptom Checker
- Sleep Recovery Score
- Energy Optimization Assessment
Understand What It Means
Based on your results, we surface the most relevant guides, biomarker references, and explainers. Every piece of content is grounded in peer-reviewed research and explains not just the what but the why.
Learn which biomarkers to pay attention to, what optimal ranges actually look like (not just "normal"), and what the current research says about your specific concerns.
What you'll learn
- Which lab markers are most relevant to your symptoms
- The difference between "normal" and optimal reference ranges
- Root causes of common issues like fatigue, weight gain, and brain fog
- Evidence-based approaches backed by clinical research
See What We Recommend
Our medical advisory team reviews supplements, lab test kits, health devices, and other products — rating them on evidence quality, value, and who they're actually for.
We're honest about what works and what doesn't. Every recommendation includes the research behind it, who it's best for, and when you might not need it.
Recommendation categories
- At-home lab test kits (hormone panels, metabolic panels, thyroid)
- Supplements with clinical trial backing
- Health monitoring devices (HRV, CGM, sleep trackers)
- Books and educational resources
Get Treated (If You Need To)
At some point information runs out and you need a clinician — someone who can order the panel, read it against optimal ranges rather than pathology thresholds, and actually prescribe. We don't practise medicine, so for that we point people to our referral partner, Opt Health.
Opt Health is a telehealth longevity practice: a 55+ biomarker blood panel drawn at home or at one of 2,000+ partner labs, an unrushed one-on-one review with a physician, and a treatment plan built off your own numbers. Medication and supplements ship to your door, and you retest to see whether the plan moved anything.
What they treat
- Hormones — testosterone, thyroid, estradiol, cortisol, DHEA
- Metabolic health — insulin resistance, weight, GLP-1 therapy
- Sleep, energy and body composition
- Peptide therapy, prescribed and monitored
- Women's hormone health, including perimenopause
