Why It Matters
Most people who take supplements never actually check whether they're working - they just keep taking them and hope. This panel re-tests the exact markers your supplements are meant to move, so you can see in black and white whether your stack is doing anything or whether it's time to adjust it.

Some testing companies count every calculated ratio and derived index as its own separate "biomarker," so a modest panel gets marketed as having 100+ biomarkers. We count every result that actually appears on your lab report - including calculated values like ratios, since those are real numbers you'll see and can verify yourself - but we don't add anything that isn't genuinely part of what gets reported, and we don't count conditional add-on tests that only run if an initial result comes back abnormal. The number you see is the number of results you'll actually get back, and you can count them yourself on your own report.
