Thyroid care that reads your full chart, not just your last TSH.
Clara reads your full thyroid history, lab results, medications, and interactions. Our physicians sign off on every dose and every lab order.

Records synced, thyroid panel read in context, dose drafted, then Clara tracks TSH on schedule.
Connect your records
Clara auto-syncs your records from 150,000+ doctors' offices, hospitals, labs, and pharmacies. Before anything is prescribed, Clara reads every TSH and Free T4 you have had drawn, any TPO or TgAb antibody results, your weight trend, your resting HR from wearables, and every medication on your chart. Free to start, no credit card.
A dose grounded in your data
Clara reads your TSH history, your symptoms, and any prior levothyroxine doses, then drafts an appropriate starting dose or dose adjustment based on your weight and medical history. Clara also checks your full medication list for any interactions before drafting a plan. Every change is reviewed and signed off by a licensed physician.
Regular retesting
Clara orders a repeat TSH at 6 to 8 weeks after any dose change, not at your next annual visit. Plans start at $25/mo for physician-approved prescriptions and lab orders. Standard ($50/mo) and Concierge ($150/mo) plans include bundled biomarker panels that capture thyroid, metabolic, and nutrient markers in one pass.
Clara notices the TSH hasn't been rechecked in 18 months and orders it before your next annual visit.
Common symptoms patients describe with an underactive thyroid.
These symptoms overlap with perimenopause, iron deficiency, sleep apnea, and depression. Clara reads all of that context at once rather than anchoring on the first plausible explanation. If TSH alone is not enough, Clara recommends other labs that might provide a better picture.
Levothyroxine dosed to your weight and TSH, with monitoring on the right cadence.
Levothyroxine (T4)
The standard of care for primary, secondary, and tertiary hypothyroidism. Clara sizes the starting dose by weight per the Synthroid label and flags interactions with calcium, iron, PPIs, estrogens, and bile acid sequestrants before drafting. Clara also checks the timing of supplements and other medications that affect absorption.
Autoimmune thyroiditis
TPO antibodies indicate Hashimoto's, which is a common cause of hypothyroidism. Clara folds antibody status into the plan, monitors for associated deficiencies (B12, vitamin D, ferritin), and surveils thyroid function on schedule even when TSH is in range, because patients with Hashimoto's can see their thyroid function decline over time.
Iron, B12, vitamin D
Persistent fatigue on levothyroxine isn't always a dose issue. Nutrient deficiencies like low ferritin, B12, or vitamin D can contribute and are worth checking. Clara reads these alongside your TSH to help identify what may be driving the symptom. Nutrient labs are included in the Standard and Concierge biomarker panels.

Clara manages thyroid care alongside blood pressure, cholesterol, and everything else. Not a one-condition practice.
Understanding your thyroid means reading years of data, not just the latest result.
TSH levels can change over time. Levothyroxine absorption changes with iron, calcium, PPIs, estrogen, and age. Hashimoto's slowly reduces thyroid function over time. The pattern that matters lives across years of labs, not just the last panel.
Reads every TSH you have ever had drawn
Clara auto-syncs from 150,000+ medical sources and cross-correlates every TSH, Free T4, antibody result, and resting HR in one pass. Single bad readings get context. Multi-year trends get surfaced.
Checks for medication interactions before prescribing
Calcium, iron, PPIs, estrogens, SSRIs, rifampin, bile acid sequestrants, soy, and coffee all affect levothyroxine absorption. Clara checks the full label against every medication and supplement on your chart before drafting a dose change.
Questions don't wait for office hours
Palpitations on a new dose. Cold intolerance that has gotten worse. A wearable resting HR that dropped 8 bpm in two weeks. Clara reads your chart and responds with context from your full history. If a dose change looks warranted, it drafts a summary and routes it to a physician for review.
An AI that reads every TSH you have ever had drawn. A physician who signs off on every dose.
