Probiotics: A Potential Strategy for Preventing and Managing Cardiovascular Disease

Probiotics are gaining recognition as a viable strategy for mitigating cardiovascular risk factors. Specifically, recent studies highlight their potential benefits in managing cholesterol levels, blood pressure, and inflammation, which are critical components in the prevention of cardiovascular diseases (CVD). This comprehensive review aims to elucidate the impact of probiotic consumption on major cardiovascular risk factors, including individuals with hypertension, type II diabetes mellitus, metabolic syndrome, hypercholesterolemia, and in secondary prevention in coronary artery disease. Scientific evidence based on human studies suggests that probiotic consumption is associated with positive effects on anthropometric measures, inflammation markers, blood pressure, glucose metabolism markers, lipid profiles, and endothelial function. However, these findings should be interpreted pragmatically and acknowledge the significant variability in results. This variability may be attributed to factors such as probiotic composition (single strain or multiple strains), the characteristics of the delivery matrix (food, capsules, and sachets), the duration of the intervention, the dosage regimen, and baseline health profiles of the participants. Incorporating probiotics as part of a comprehensive and healthy lifestyle approach can be considered a feasible strategy for both the prevention and management of CVD. However, further research is needed on factors influencing the effect of probiotics, such as: (i) optimal probiotic strain(s), (ii) appropriate dosage, (iii) duration of treatment, (iv) optimal delivery vehicle, and (v) sex-specific differences.
