The Effect of Spirulina Supplementation on Blood Pressure in Adults: A GRADE-Assessed Systematic Review and Meta-Analysis of Randomized Clinical Trials.
Previous studies have yielded controversial results regarding the effect of spirulina on blood pressure (BP), which need updating. So, this updated systematic review and meta-analysis of randomized controlled trials (RCTs) carry out a more accurate estimation of the effect of spirulina on BP in adults. This systematic searches (in PubMed/Medline, Scopus, and ISI Web of Science) until April 1, 2024, to identify related RCTs based on PICOS guidelines (population (individuals > 18 years old), the intervention (spirulina), the comparison (control or placebo group), the outcomes (systolic BP (SBP) and diastolic BP (DBP)), the study design (RCTs)), and PRISMA-checklist (Supporting Information, data S2). We evaluated the impact of spirulina on DBP and SBP. Conventional procedures were employed for analyzing publication bias, heterogeneity, and sensitivity. The GRADE criteria and the Cochrane assessment method were employed to evaluate the risk of bias (ROB) and certainty of evidence across the studies, respectively. The result shows spirulina consumption decreases SBP (WMD: -4.41 mmHg, 95% CI: -6.74 to -2.07, I2 = 66.1%) and DBP (WMD: -2.84 mmHg, 95% CI: -4.65 to -1.03, I2 = 62.3%). Subgroup analysis demonstrated SBP and DBP were still lower in individuals with ≥ 120 and ≥ 80 mmHg, hypertension (HTN) individuals, overweight individuals, age > 50 years, and > 8 weeks of intervention. Indeed, we do not observe publication bias, ROB, or interference studies in the overall results of BPs, and based on GRADE, our outcomes have moderate quality. Because of the low number of studies and participants, the dose-response and meta-regression are not significant. His study demonstrated spirulina intervention decreased SBP and DBP in HTN and overweight individuals, age > 50 years, and > 8 weeks of intervention. So, spirulina intake decreases BP and could be used in clinical practice. Furthermore, more and high-quality RCTs are needed to establish the clinical efficacy of the spirulina and determine cutoff spirulina interventions based on dose and duration.

期刊介绍：
Phytotherapy Research is an internationally recognized pharmacological journal that serves as a trailblazing resource for biochemists, pharmacologists, and toxicologists. We strive to disseminate groundbreaking research on medicinal plants, pushing the boundaries of knowledge and understanding in this field.
Our primary focus areas encompass pharmacology, toxicology, and the clinical applications of herbs and natural products in medicine. We actively encourage submissions on the effects of commonly consumed food ingredients and standardized plant extracts. We welcome a range of contributions including original research papers, review articles, and letters.
By providing a platform for the latest developments and discoveries in phytotherapy, we aim to support the advancement of scientific knowledge and contribute to the improvement of modern medicine.
