Aged Garlic Extract: Clinical Evidence & Substantiation Summary
What Is Aged Garlic Extract?
Aged garlic extract (AGE) is produced by ageing raw garlic in ethanol for 20+ months, producing unique organosulfur compounds including S-allylcysteine (SAC). Clinical evidence strongly supports its cardiovascular benefits.
Mechanism of action: SAC and other AGE compounds inhibit cholesterol synthesis (HMG-CoA reductase), reduce platelet aggregation, improve endothelial function via eNOS activation, and lower blood pressure through ACE inhibition and hydrogen sulfide production.
Clinical Evidence Summary
Below are 3 key clinical studies on Aged Garlic Extract. Nutra Comp analyses 48+ studies in its full clinical evidence report.
Garlic supplementation and blood pressure: updated meta-analysis
Population: 20 RCTs, 970 participants
Key finding: Garlic supplementation reduced SBP by 8.3 mmHg (p<0.001) and DBP by 5.5 mmHg (p<0.001) in hypertensive individuals.
Aged garlic extract and lipid profile
Population: 12 RCTs
Key finding: AGE reduced total cholesterol by 17 mg/dL (p=0.001) and LDL cholesterol by 9 mg/dL (p=0.01) after ≥12 weeks.
Garlic and coronary artery calcification
Population: 45 adults
Key finding: AGE (2,400 mg/day) significantly slowed progression of coronary artery calcification by 48% versus placebo over 12 months (p=0.01).

Frequently Asked Questions
Is garlic extract FDA approved?
Garlic extract is a dietary supplement under DSHEA. Kyolic® aged garlic extract is the most clinically studied form.
What's the difference between aged and fresh garlic?
Ageing converts harsh, unstable allicin into stable, odourless SAC compounds. Aged garlic extract has more consistent bioactivity and fewer GI side effects.
What dosage is used in clinical studies?
Most studies use 600–2,400 mg/day of aged garlic extract. The blood pressure meta-analysis found effects at ≥600 mg/day.
