# University of Freiburg sauerkraut blood pressure study > Live situation record from CLSTR: https://clstr.news/situations/university-of-freiburg-sauerkraut-blood-pressure-study > Updated: 2026-08-11T13:36:52.000Z. Sources: 4. Developments: 2. Researchers at the University of Freiburg conducted a randomized crossover trial involving 87 healthy adults to investigate the effects of sauerkraut consumption on cardiovascular health. The study, published in the European Journal of Clinical Nutrition, found that consuming 100 grams of sauerkraut daily for four weeks resulted in a modest average reduction in systolic blood pressure of between 1.5 and 2.5 mmHg. The findings indicated that both fresh and pasteurized sauerkraut provided similar benefits. This suggests that the cardiovascular effects may be driven by organic acids and metabolites produced during fermentation rather than live probiotics. The most significant reductions in blood pressure were observed in participants under the age of 50. Researchers noted that while the results are statistically significant, sauerkraut should be viewed as a modest dietary tool rather than a primary treatment for cardiovascular disease. ## Timeline ### 2026-08-11: University of Freiburg study finds sauerkraut may lower blood pressure A University of Freiburg study found that eating 100g of sauerkraut daily for four weeks can modestly lower systolic blood pressure, regardless of whether the product contains live probiotics. 2 sources. https://clstr.news/cluster/university-of-freiburg-study-finds-sauerkraut-may-lower-blood-pressure ### 2026-08-08: University of Freiburg study links sauerkraut to lower blood pressure Researchers at the University of Freiburg found that daily consumption of sauerkraut can measurably lower systolic blood pressure, with benefits persisting even in pasteurized versions. 2 sources. https://clstr.news/cluster/university-of-freiburg-study-links-sauerkraut-to-lower-blood-pressure --- Cite as: University of Freiburg sauerkraut blood pressure study.
