(1) Background: Lifestyle changes, eventually associated with a nutraceutical, are recommended strategies for managing high-normal blood pressure (BP) patients with low-moderate cardiovascu-lar (CV) risk. Nitrates-enriched products (i.e., red beet extracts) may help reduce BP, exerting vas-oactive properties and enhancing adherence to lifestyle advice. Our study aimed to evaluate the effectiveness in clinical practice of generic written lifestyle advice and a beetroot-based nutraceu-tical prescription based on the 2018 ESC/ESH guidelines on 24-hour BP in a population with high-normal BP and low-moderate CV risk.; (2) Methods: A longitudinal observational study was con-ducted in two ESH hypertension excellence centres on 43 consecutive subjects with high-normal BP based on repeated office BP (OBP) measurements and a low-moderate CV risk. Twenty-four-hour ambulatory BP monitoring (ABPM) was carried out at baseline and three months after ge-neric written ESC/ESH advice for lifestyle changes associated with a nutraceutical containing 500 mg of dry beetroot extract; (3) Results: Mean age 50±11 years, 54% males, 58% overweight/obese, mean OBP 135±3/85±3 mmHg. At baseline, 24-hour BP, daytime BP and night-time BP were 127±7/80±6 mmHg, 131±8/83±6 mmHg and 118±8/70±5 mmHg, respectively, BP profiles compat-ible with hypertension status in some subjects. After a median follow-up of 98 (92-121) days, all BPs, except night-time diastolic BP, were significantly decreased: -3±6/-2±4 mmHg for 24-hour BP, -3.9±6.0/-3.0±4.0 mmHg for daytime BP and -3.3±7.4/-1.3±4.7 mmHg for night-time BP, respec-tively. No significant clinical changes in weight were detected. BP decreased independently of baseline BP level, gender, smoking status and BMI, while a more substantial decrease in BP was observed in older patients; (4) Conclusions: Our pilot study shows for the first time that written generic lifestyle advice based on ESC/ESH hypertension guidelines coupled with a beetroot-based nutraceutical may represent a valid initial non-pharmacological approach in subjects with high-normal BP and low-moderate CV risk even without personalized diet interventions.
