Garlic Supplements Lower Blood Pressure and Cholesterol, Prevent Infections

Study Title: 'Garlic Lowers Blood Pressure in Hypertensive Individuals, Regulates Serum Cholesterol, and Stimulates Immunity: An Updated Meta-analysis and Review."
Number of Participants: 20 trials with 970 participants
Length of Study: 20 studies of variable length
Type of Study: Meta-Analysis of randomized controlled trials (RCTs)
Publication: The Journal of Nutrition
Study Result: Study Authors: "Our review suggests that garlic supplements have the potential to lower blood pressure in hypertensive individuals, to regulate slightly elevated cholesterol concentrations, and to stimulate the immune system. Garlic supplements are highly tolerated and may be considered as a complementary treatment option for hypertension, slightly elevated cholesterol, and stimulation of immunity."

In this meta-analysis of 20 random controlled trials, garlic supplements were found to lower blood pressure in patients with high blood pressure (≥140/90 mm Hg) by an average of 8.7 mm Hg for systolic and 6.1 for diastolic blood pressure. The study previously found garlic to be effective in reducing total and LDL cholesterol by 10% if taken for >2 mo by individuals with slightly elevated cholesterol levels. Clinical trials have shown garlic to significantly reduce the number, duration, and severity of upper respiratory infections.

Editor’s Note: Since garlic works in several ways to reduce the risk of cardiovascular disease, by reducing blood pressure, reducing cholesterol, and thinning the blood, it is an excellent food and supplement for anyone concerned about heart disease. Garlic extracts standardized for allicin have the most consistent effects in studies.
