Current clinical trials and systematic reviews support the claim that garlic supplementation can help lower cholesterol and reduce blood pressure.
The retrieved literature contains multiple randomized controlled trials and meta-analyses (such as papers 5, 7, and 9) specifically investigating Allium sativum (garlic) and reporting statistically significant reductions in cholesterol, LDL, and blood pressure parameters. Other papers in the prompt investigate different supplements (spirulina, soy, vitamin D, green tea, probiotic yogurt) and are tangential, while papers 10 and 11 provide additional animal or combined data. The specific garlic papers consistently support the claim.
