Benefits of Garlic Extract (Aged / Allicin)

Evidence-Based Benefits

• Blood pressure reduction — Ried et al. (2016) meta-analysis of 20 RCTs found garlic supplementation reduced systolic BP by 5.1 mmHg and diastolic BP by 2.5 mmHg in hypertensive individuals, comparable to some first-line antihypertensive medications.
• Cholesterol management — a 2018 meta-analysis in Medicine found garlic supplements reduced total cholesterol by 17 mg/dL and LDL by 9 mg/dL on average, with greater effects in those with elevated baseline levels.
• Arterial health — Matsumoto et al. (2016) demonstrated that aged garlic extract reduced coronary artery calcification progression by 80% compared to placebo over 12 months, suggesting protection against atherosclerosis.
• Anti-platelet activity — garlic compounds inhibit platelet aggregation through multiple pathways, including thromboxane synthesis inhibition, potentially reducing thrombotic cardiovascular event risk.

What the Research Says

Garlic is among the most extensively studied cardiovascular supplements. Ried et al. (2016) published the definitive meta-analysis on garlic and blood pressure, confirming clinically meaningful reductions in hypertensive patients. Matsumoto et al. (2016) provided compelling evidence that aged garlic extract slows coronary artery calcification progression. Sobenin et al. (2008) demonstrated cholesterol-lowering effects in a time-release garlic powder preparation. The key distinction is between aged garlic extract (standardized to S-allylcysteine) and allicin-based products — AGE has the most consistent clinical evidence and better tolerability.
