Science Corner

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

Exercise & Recovery

Work smart, not just hard.

Recovery is the curing phase — where the body hardens, adapts, and actually becomes stronger. The podium isn't won by who does the most work; it's won by who absorbs the most. Real-time recovery biomarkers — from a phosphate recovery test that tracks the ATP building block to metabolic buffer and magnesium — turn recovery from guesswork into an active strategy.

KetKetonesConfirms your metabolic zone — whether your body has switched to burning fat for fuel.
MgMagnesiumVital for muscle function and relaxation. Check excretion so you aren't running low.
HCO₃Metabolic BufferBicarbonate reserves that buffer the acid your muscles produce under intense load.
PO₄PhosphateThe energy mineral — a key building block of ATP, your cellular fuel.
ZnZincEssential trace mineral for immune and metabolic support during active recovery.

How to Use BodyCheck - Use Cases

A routine repeats. A protocol reacts to your data.

01

After a brutal tempo run

You're in an acidic, metabolically stressed state and reaching for recovery supplements.

The protocol

Instead of "magnesium every night," take it only when Metabolic Buffer and pH show you're genuinely under stress.

Metabolic BufferpH BalanceMagnesium
02

Race-week hydration

Every athlete sweats differently — 1–2 L/hr, some salty, some not. Thirst is a terrible gauge.

The protocol

Read Specific Gravity and Chloride together to dial fluid and electrolytes to your exact sweat rate.

Specific GravityChloride
03

Auditing your supplements

You're stacking pills and hoping they're actually absorbing.

The protocol

If Mineral Load spikes right after a dose, you've hit your absorption limit — stop wasting money on more.

04

Dialing in a clean diet

You eat your greens but can't see whether it's working.

The protocol

Track Dietary Nitrates, Alkaline Buffer and Vitamin C to confirm your nutrition is filling measurable gaps.

05

Confirming ketosis

You're cutting carbs and want proof the switch actually flipped.

The protocol

Track Ketones to know the exact moment your metabolism switches to burning fat for fuel.

Ketones
01

Non-invasive

Urine summarizes what your body has processed and discarded over the last several hours — no needles, no draws.

02

Daily, not 2–4× a year

A blood draw is a single-moment snapshot. Urine testing is a habit you can run every single day.

03

Tactical, not abstract

Biomarkers become real-time data you can act on between sessions — measured to CLSI standards.

Data is only as powerful as your ability to use it.
