Can probiotics help reduce cardiovascular risk? A meta-analysis published in Annals of Medicine (2015;47(6):430–440. doi:10.3109/07853890.2015.1071872) examined whether probiotic supplementation was linked with changes in blood lipids and other markers associated with cardiovascular disease.
The analysis included 15 studies published between 2000 and 2014, involving a total of 788 participants. Across these trials, probiotic use was associated with statistically significant improvements in several cardiovascular risk factors. These included reductions in total cholesterol, LDL cholesterol, body mass index, waist circumference, and certain inflammatory markers.
Based on these pooled findings, the authors concluded that probiotic supplementation appears to be effective in improving lipid profiles and other coexisting factors linked with cardiovascular risk. While these results do not demonstrate prevention of heart attacks, they suggest that the gut microbiome may play a role in metabolic and inflammatory processes relevant to cardiovascular health.
As with all meta-analyses, the findings reflect averages across studies with varying designs and probiotic strains, and further well-controlled research is needed to clarify clinical relevance and long-term outcomes. It seems that good gut health may improve cardiovascular health; click to learn more.
