Early Access · Launching 2026

Your family history
isn't your fate.

Get ahead of your health.

A comprehensive liquid health check for prevention. One blood draw measures 70+ routine markers and 1,000+ proteins across your key organ systems. Your clinician builds a precision intervention plan around what they find, and retests in 4 to 6 months to prove it's working at the molecular level.

No spam, ever.

Test. Intervene. Retest. See your biology change.

Why this exists

The healthcare system has two settings: healthy and sick.
Millions of us are neither.

Family history is a biological signal — heart disease, dementia, and metabolic disease run in families, passed down through shared biology. For people who carry that risk, there is a missed opportunity to act until symptoms appear. Kale is built to help you monitor and manage your risk of disease before it becomes one.

Your clinician reviews everything
A licensed clinician reads your report before you do. You meet with them to walk through your results, ask questions, and discuss your history. They provide a precision intervention plan and refer for imaging where your signals warrant a closer look.

Retest at 4 to 6 months
The retest proves whether your interventions are working at the molecular level. One timepoint is a snapshot. Two timepoints is a trajectory.
What standard testing misses

The same organ.
Two completely different pictures.

Your liver
Biological age +6 years faster than expected for your age and sex.
We picked up signals associated with three biological processes in your liver.
Hepatic Metabolic Stress
Proteins associated with how your liver processes and stores fat. This pattern is not measurable on standard liver panels.
Signal detected
Hepatic Inflammation
Proteins associated with your liver's inflammatory response. Not yet reflected in standard ALT/AST values.
Signal detected
Hepatic Fibrotic Signalling
Proteins associated with structural repair and scarring. No pattern of concern for your age and sex.
No signal detected
Your clinician's plan
↺
Zone 2 cardio, 150 min/week. RCT evidence supports 20 to 30% liver fat reduction over 12 weeks at this dose.
⏱
Time restricted eating, 14 hour fast daily. Reduces hepatic lipogenesis. Specific to your fat metabolism signal.
+
Omega-3 EPA/DHA 2g/day and Vitamin E 400 IU. Evidence-based for hepatic inflammatory processes at this dose.
🍷
Alcohol under 7 units/week. The threshold above which hepatic inflammatory burden increases given your current signals.
↗
FibroScan referral sent. Non-invasive liver imaging to stage and confirm.
↻
Retest in 4 months. Signals tracked. Protocol adjusted based on what moves and what does not.
Kale reports blood biomarkers alongside research-grade population proteomic signals to support clinician interpretation. They are not clinical diagnostic tests and do not constitute a medical diagnosis. All signals are reviewed by a licensed clinician before delivery.
The loop

Measure whether your interventions
are actually working.

The proteins in your blood reveal how your interventions are actually impacting your biological markers. Retest every 4 to 6 months and see, at the molecular level, whether what you are doing is making a difference.

Organ-level proteomic aging is one of the most replicated findings in recent biology. Protein signatures in blood reflect the biological age of individual organs and predict major disease outcomes years before symptoms appear.
