| Beetroot Nitrate Blood Pressure Randomized Trial | Background/Objectives: Health challenges associated with metabolic syndrome (MetS) have stimulated investigations into the effectiveness of nutraceutical interventions, including beetroot juice (BRJ), in mitigating MetS risk factors. | 4 | Haswell C (2026) | Effects of Nitrate- and Betalain-Rich Beetroot Juice Ingestion on Vascular Function and Metabolic Syndrome Risk Factors in Healthy Adults: A Pilot Study. |
| Beetroot Nitrate Blood Pressure Randomized Trial | Conclusions: Supplementation with BRJ reduced SBP relative to placebo, and the betalain-rich NZBR also reduced SVR, whereas the higher-nitrate UKBR did not. | 4 | Haswell C (2026) | Effects of Nitrate- and Betalain-Rich Beetroot Juice Ingestion on Vascular Function and Metabolic Syndrome Risk Factors in Healthy Adults: A Pilot Study. |
| Beetroot Nitrate Blood Pressure Randomized Trial | Methods: This repeated-measures crossover trial ( n = 16 healthy participants) investigates the effects of daily ingestion of two different BRJs [United Kingdom beetroot juice (UKBR), 1280 mg nitrate, 147 mg betalains; New Zealand beetroot juice (NZBR), 1120 mg nitrate, 506 mg betalains] and placebo (PL) on plasma nitrate and nitrite levels, MetS biomarkers and systemic vascular resistance (SVR). | 4 | Haswell C (2026) | Effects of Nitrate- and Betalain-Rich Beetroot Juice Ingestion on Vascular Function and Metabolic Syndrome Risk Factors in Healthy Adults: A Pilot Study. |
| Beetroot Nitrate Blood Pressure Randomized Trial | Nitrate, produced endogenously, and absorbed from dietary sources (e.g., beetroot), is concentrated in/secreted by the salivary glands and reduced by lingual bacterial nitrate reductases to nitrite (the 'enterosalivary circulation'). | 4 | Webb AJ (2026) | Lowering salivary pH with sugar-containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice). |
| Beetroot Nitrate Blood Pressure Randomized Trial | Following systemic absorption, nitrite is further reduced to vasodilating NO intravascularly. | 4 | Webb AJ (2026) | Lowering salivary pH with sugar-containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice). |
| Beetroot Nitrate Blood Pressure Randomized Trial | Systolic and diastolic BP were decreased by 2.7 ± 0.5 and 1.9 ± 0.5 mmHg, respectively (both p Conclusion Acutely lowering salivary pH (with sugar-containing gum) augments salivary nitrite production, plasma [nitrite] and BP-lowering with dietary nitrate. | 4 | Webb AJ (2026) | Lowering salivary pH with sugar-containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice). |
| Beetroot Nitrate Blood Pressure Randomized Trial | Aims The nitrate-nitrite-nitric oxide (NO) pathway has a wide range of effects including blood pressure (BP) regulation. | 4 | Webb AJ (2026) | Lowering salivary pH with sugar-containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice). |
