Hidden heart helper: Nitrate-Fortified biscuits could lower blood pressure
NCT ID NCT07172425
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a safe amount of nitrate—a natural compound found in leafy greens and beetroot—to common oat-based foods like biscuits, cereal bars, and porridge can improve nitric oxide levels and lower blood pressure. Thirty healthy adults will try each fortified food in a random order, and researchers will measure nitrate levels in their blood, saliva, and urine over 24 hours. The goal is to find an affordable, tasty way to support heart health for everyone.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
inorganic potassium nitrate added to oat-based foods (biscuits, cereal bars, porridge)
What this could lead to
If successful, this could point toward a simple, low-cost way to add heart-healthy nitrate to common foods, potentially helping manage blood pressure in populations that cannot afford expensive supplements.
What could go wrong
This is a very early, small study in only 30 healthy volunteers. It tests short-term effects, not long-term benefits or real-world use. The results may not apply to people with high blood pressure or other health conditions.
