NT-proBNP

Advanced wellness

also n-terminal pro-b-type natriuretic peptide

What it isA fragment released when ventricular heart muscle is stretched or pressure-loaded. The heart cleaves a precursor protein into the active hormone (BNP) and this stable, easily-measured fragment (NT-proBNP).

DoesSignals the kidneys to excrete sodium and water and dilates blood vessels — the heart's own way of unloading pressure.

GoodLow NT-proBNP confirms an unstressed heart and intact diastolic and systolic.

BadElevated NT-proBNP signals heart failure, volume overload, or chronic cardiac stress, and predicts cardiovascular events and mortality.

Standard

<125 pg/mL (age <75); <450 pg/mL (age ≥75).

Optimal

10–50 pg/mL (lower is good)

Modifiers

Rises with age, kidney disease, obesity (paradoxically lowers); also rises in atrial fibrillation.

How to optimize

Supplements: Omega-3 EPA+DHA (2–4g/day), CoQ10 (200mg/day), magnesium glycinate (300mg/day), taurine (3g/day).
Peptides: —
Drugs: ACE inhibitors, ARBs, ARNI (sacubitril/valsartan), beta-blockers, SGLT2 inhibitors, mineralocorticoid receptor antagonists.
