Insights
The science, in the moments that matter.
For those who refuse to settle for average, the margin between a podium finish and the middle of the pack is written in your training. BodyCheck translates urine biomarkers into tactical data — so you train on truth, not guesswork.
The biomarker index — 12 markers, 3 pillars
Explore what BodyCheck actually reads.

Pillar 01
Hydration
Manage hydro-dynamics, not just water.
Blood is your engine's coolant. When you sweat you lose blood volume — the heart works harder, muscles get less oxygen, you overheat. Most athletes estimate fluid needs with formulas like the Galpin equation, but that's still a guess. BodyCheck shows you how to measure hydration directly: reading Specific Gravity and Chloride together gives you a real hydration index, so you can measure your hydration level every day instead of estimating it — calibrated to your exact sweat rate and workload.
How often to test
Built for a daily habit, not a yearly check-up.
Most people get blood work a few times a year. A BodyCheck test takes one urine sample and about two minutes, so you can test as often as your training demands.
No needles, no draws
Urine reflects what your body has processed over the last several hours. One sample is all it takes, so testing often is easy to keep up.
Daily, for serious training
For athletes in a training block, bodybuilders on a cut or bulk, and biohackers running a protocol. Test each morning to learn your typical range and catch changes the day they happen.
1–2 times a week, for a check-in
For staying on track between goals. A weekly check shows how your hydration, diet and recovery are trending. When you want sharper answers, step up to daily.
Going deeper? Test throughout the day.
Run several tests in one day to see how your body responds to training, food and rest in real time.
- Morning
Set your baseline after a night's sleep, before food or training.
- After a workout
See what the session cost you in hydration, electrolytes and metabolic buffer.
- Before bed
Confirm you've rehydrated and replaced what you lost, so tomorrow starts in range.
How to Use BodyCheck - Use Cases
A routine repeats. A protocol reacts to your data.
Race-week hydration
Every athlete sweats differently — 1–2 L/hr, some salty, some not. Thirst is a terrible gauge.
Read Specific Gravity and Chloride together to dial fluid and electrolytes to your exact sweat rate.
After a brutal tempo run
You're in an acidic, metabolically stressed state and reaching for recovery supplements.
Instead of "magnesium every night," take it only when Metabolic Buffer and pH show you're genuinely under stress.
Auditing your supplements
You're stacking pills and hoping they're actually absorbing.
If Mineral Load spikes right after a dose, you've hit your absorption limit — stop wasting money on more.
Dialing in a clean diet
You eat your greens but can't see whether it's working.
Track Dietary Nitrates, Alkaline Buffer and Vitamin C to confirm your nutrition is filling measurable gaps.
Confirming ketosis
You're cutting carbs and want proof the switch actually flipped.
Track Ketones to know the exact moment your metabolism switches to burning fat for fuel.
Data is only as powerful as your ability to use it.
