Our Picks

Lab test kits, supplements, devices, and resources reviewed by our medical advisory team — with honest assessments of what works, what doesn't, and who it's for.

At-Home Lab Tests

Get the biomarkers that matter without waiting for a doctor's order. These are the panels our medical team recommends most.

Lab Test

Comprehensive Metabolic Panel

Covers fasting insulin, HbA1c, fasting glucose, lipid panel, hs-CRP, and uric acid. The gold standard for catching insulin resistance and metabolic syndrome early.

Best for: Anyone with unexplained weight gain, energy crashes, or family history of type 2 diabetes.

Lab Test

Complete Hormone Panel

Total and free testosterone, estradiol, DHEA-S, SHBG, TSH, free T3, free T4, AM cortisol, FSH, and LH. Goes well beyond the single-marker screening most doctors order.

Best for: Fatigue, low libido, mood changes, suspected thyroid issues, or perimenopause symptoms.

Lab Test

Fatigue & Recovery Panel

Ferritin, vitamin D (25-OH), RBC magnesium, B12, thyroid panel, cortisol, CBC, and hs-CRP. Targets the physiological causes of fatigue that sleep hygiene won't fix.

Best for: Waking unrefreshed, afternoon crashes, poor HRV, or chronic tiredness despite adequate sleep.

Supplements

Only compounds with clinical trial evidence. We skip the trendy stuff and focus on what actually moves biomarkers.

Supplement

Magnesium Glycinate

Supports 600+ enzymatic processes including sleep regulation and glucose metabolism. Glycinate form has superior bioavailability and minimal GI side effects compared to oxide or citrate.

Evidence: Clinical trials show improvements in sleep quality, insulin sensitivity, and HRV. Deficiency is common — serum magnesium misses 80% of cases.
Supplement

Vitamin D3 + K2

Vitamin D insufficiency (<30 ng/mL) affects an estimated 42% of US adults. K2 ensures calcium is directed to bones rather than arteries.

Evidence: Meta-analyses link optimal vitamin D (40-60 ng/mL) to improved insulin sensitivity, immune function, and sleep quality.
Supplement

Berberine

Plant alkaloid studied as a glucose-lowering agent. Multiple RCTs show it reduces fasting glucose and HbA1c comparably to metformin in some populations.

Evidence: A 2024 meta-analysis of 46 RCTs confirmed significant reductions in fasting glucose, HbA1c, and HOMA-IR. Not a substitute for medical treatment.

Health Devices

Monitoring tools that provide actionable data over time — not just one-time snapshots.

Device

Continuous Glucose Monitor (CGM)

Tracks real-time glucose responses to food, exercise, stress, and sleep. Reveals patterns a single fasting glucose test can't. Brands like Dexcom, Libre, and Levels offer consumer-accessible options.

Best for: Insulin resistance investigation, weight loss plateaus, or anyone curious about their glycemic responses.
Device

HRV & Sleep Tracker

Devices like Oura Ring, Whoop, and Apple Watch track heart rate variability, resting heart rate, and sleep stages — providing trends that reflect autonomic nervous system health.

Best for: Recovery monitoring, stress tracking, and sleep quality assessment over weeks and months.
