Brain natriuretic peptide (BNP) is a natural heart hormone used clinically as a biomarker in heart failure evaluation. It is not a wellness peptide. External BNP affects blood pressure and fluid balance and can cause dangerous hypotension.
Common reasons people consider it
- clinical relevance as a heart-failure biomarker (BNP/NT-proBNP)
- physiology relevance in natriuresis and vascular tone regulation
Most commonly reported downsides
- lightheadedness from lower blood pressure
- headache
- fatigue
Rare but important symptoms to watch for
These are uncommon, but if they occur, stop and seek medical care.
- fainting or severe dizziness
- dangerous low blood pressure symptoms (confusion, collapse)
- signs of electrolyte imbalance (severe weakness, palpitations)
Who should be cautious
- people with low blood pressure or on vasodilators/blood pressure meds
- people with kidney disease or unstable fluid balance
- pregnant or breastfeeding individuals
- adolescents (high consequence plus limited context for use)
