Garmin · AI primary care

A Garmin tells you your VO2 max dropped. Clara tells you why.

Clara reads your VO2 max, HRV, and training-load trend against your full chart, labs, and medications. Free to connect records and start chatting.

Get started How it works

My VO2 max has been dropping for three months. Training's the same and I feel flat.

Clara

Your VO2 max fell from 52 to 46 with training load flat. Your October ferritin was 28, low for a heavily training male; I'd order ferritin, iron studies, and TSH. Our doctor signs off.

Run the labs.

How it works

Connect Garmin Connect. Clara reads the stream against your chart.

Connect Garmin and your records

Clara pulls your Garmin data (VO2 max, HRV status, Body Battery, training load, resting HR, sleep stages, stress) and auto-syncs your medical records from 150,000+ doctors' offices, hospitals, clinics, and labs. No PDFs, no faxed labs. Free to start.

Clara reads the trend, not the ride

A single long run can swing every Garmin metric. The signal is the multi-week trajectory. Clara cross-references rolling Garmin data against your medications, recent labs, hydration patterns, and seasonal training context, and flags the inflections that map to something clinical.

Chat, labs, or Rx when warranted

Ask Clara anything. When the pattern points at something treatable (iron depletion, subclinical hypothyroidism, overtraining syndrome, dehydration-adjacent electrolyte issues), a licensed physician reviews Clara's plan and signs off on lab orders or prescriptions. FDA-approved prescriptions and ad-hoc lab work may be covered by your insurance.

What Clara watches

The Garmin metrics with the most clinical signal.

VO2 max

VO2 max trend as a longevity marker

Garmin's estimated VO2 max is one of the most validated longevity signals any consumer wearable produces. A sustained decline without a training-load explanation is a real clinical signal: iron depletion, subclinical thyroid issues, early cardiac disease, chronic underfueling. Clara reads the trend against your recent labs.

HRV status

HRV status flips and recovery collapse

Garmin's HRV status (balanced / unbalanced / low / poor) is a useful aggregation of nightly HRV against your baseline. A multi-week flip from balanced to unbalanced or low, combined with a rising resting HR, points at overtraining, subclinical infection, disturbed sleep, or a medication change. Clara reads it against your chart, not in isolation.

Body Battery

Chronically low Body Battery

Body Battery persistently running in the 20s is a pattern, not a bad week. Chronic low values with normal training load track with overtraining, iron depletion, untreated sleep-disordered breathing, depression, and thyroid issues. Clara queues the right lab panel based on the pattern you're showing.

Training load & recovery

Training load vs. recovery mismatch

Garmin's training load and acute-to-chronic ratio capture overreach clearly. Clara uses it as context to distinguish "training stress with normal recovery" from "something clinical". A flat training load plus a deteriorating recovery profile is almost never overtraining. That pattern deserves labs.

The AI difference

Garmin is extraordinary at measurement. It is not a clinician.

Garmin Connect shows you every metric. It cannot tell you that your falling VO2 max matches your dropping ferritin from six months ago, or that your flipping HRV status started the week your SSRI dose changed. Those are cross-reference questions against a chart. Clara has the chart, runs the cross-reference in seconds, and turns the answer into a drafted lab order or prescription.

Cross-reads Garmin against your labs

Most unexplained VO2 max declines in healthy adults map to iron status, thyroid function, subclinical sleep-disordered breathing, or underfueling. Clara reads the trend against your ferritin, iron studies, TSH, vitamin D, and B12, and queues the right follow-up.

Separates training stress from clinical signal

Garmin's training-load metrics are the best consumer proxy for training stress. Clara uses them as context, not as an answer. A flat training load with deteriorating recovery is almost never overtraining; that pattern deserves labs, and Clara orders them.

Medication-aware pattern recognition

Your beta blocker will suppress Garmin's HR zones and distort VO2 max estimates. Your SSRI will flatten HRV for weeks. Your GLP-1 will change resting HR. Clara with the full medication list open stops misreading expected pharmacology as "declining fitness", and catches the drug effect that actually is pathologic.

Common questions

Garmin with Clara: the questions patients actually ask.

What does Clara cost?

Connecting your medical records and chatting with Clara is free. Wearable integration (Garmin, Oura, Eight Sleep, Fitbit, Peloton, Whoop, Apple Watch) is included with the Standard plan at $50/month, which also includes 74 biomarker tests as part of the membership (not billed separately, not billed to insurance). All plans are HSA/FSA eligible. Prescriptions Clara writes and ad-hoc lab orders are billed by your pharmacy or lab and may be covered by your insurance.

How does Clara use my Garmin data?

Clara pulls your VO2 max, HRV status, Body Battery, training load, resting HR, sleep stages, and stress data from Garmin Connect and reads them against your full medical chart: current medications, recent labs, prior diagnoses, and anything else in the record. When a pattern intersects with something clinical, Clara surfaces it and queues the right next step.

My VO2 max has been declining. What can Clara actually do?

A sustained VO2 max decline without a training-load explanation is a genuine clinical signal. Clara reads it against your chart and orders the right panel: ferritin and iron studies for the most common driver (iron depletion, especially in endurance athletes and menstruating adults), TSH for thyroid, CBC, vitamin D, B12, and, if the picture suggests it, a lipid panel and fasting glucose. For a deeper dive, see longevity labs.

Is Clara a real medical practice?

Yes. Clara is licensed in all 50 states. All diagnoses, prescriptions, and lab orders are reviewed and signed off by licensed physicians. Clara's AI handles intake, continuous monitoring, and clinical reasoning.

How is this different from my regular doctor?

Can your old doctor read your entire medical chart and every Garmin activity and recovery metric you've recorded this year, every time you meet? Clara can. A sports-medicine visit might look at VO2 max once. Your PCP will not. Clara reads the trajectory continuously and queues the right workup when the Garmin trend says something the annual physical won't catch. For broader primary-care context, see AI primary care or longevity.

Can I use my insurance, HSA, or FSA?

Clara's membership is cash-pay, not billed through insurance, but every plan is HSA/FSA eligible so you can pay it with pre-tax dollars. Prescriptions Clara writes go to your pharmacy and may be covered by your plan like any other script; ad-hoc lab orders at Labcorp or Quest may be covered when applicable. The 74-test biomarker panel bundled into the Standard plan is a separate category. That cost is included in the membership itself and is not billed to your insurance.

Is my Garmin and medical data private?

Clara is HIPAA compliant. Your Garmin data and medical records are used to personalize your care. They are not sold, and they are not used to train public AI models.
