# Nitrate-Rich Beetroot Interventions University of Exeter Introduced a Beetroot Juice Protocol By Debra John | Written with AI assistance | Published 2026-03-09 | Updated 2026-03-13 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/beetroot-juice-protocol References: [naturalnews](https://www.naturalnews.com/2026-03-03-beet-juice-blood-pressure-older-adults.html)  Researchers at the [University of Exeter](https://www.trendhunter.com/trends/time-traveler) introduced a concentrated beetroot juice protocol that lowered blood pressure in older adults, featuring a twice-daily dose of nitrate-rich juice designed to reshape the [oral microbiome](https://www.trendhunter.com/trends/myfitstrip). The trial compared 39 younger and 36 older participants and found a meaningful systolic drop only in the older group after two weeks. Using gene sequencing, the team reported that the intervention suppressed inflammation-linked bacteria such as Prevotella while boosting nitrate-converting strains like Neisseria, which produce nitrite from dietary nitrate; nitrite then converts to nitric oxide, a vasodilator. The study recommended roughly half to one cup of beetroot juice daily or equivalent servings of [nitrate-rich vegetables](https://www.trendhunter.com/trends/wakunaga-of-america). For consumers, the finding suggests a simple dietary strategy to improve vascular function and circulation in aging adults, supporting blood-pressure management and exercise recovery. The work highlights how targeted foods can remodel microbial communities to restore age-declining nitric oxide production.
