What it is
Aged Garlic Extract (AGE), often sold under the brand name Kyolic, is produced by slicing garlic and soaking it in ethanol for up to 20 months. This process converts the harsh, unstable allicin into stable, water-soluble sulfur compounds like S-Allyl-Cysteine (SAC).
Because SAC is highly bioavailable (nearly 100% absorption) and doesn't cause the 'garlic breath' associated with allicin, AGE is often the preferred choice for long-term heart health supplementation. It is less of an 'anti-microbial' and more of a 'vascular antioxidant' than raw garlic.
What the research says
Aged garlic has its own unique body of research. Coronary Calcium. A landmark study in The Journal of Nutrition showed that AGE significantly reduced the progression of coronary artery calcification in patients on statin therapy. Arterial Stiffness. It is particularly effective at reducing 'stiffness' in the arteries, which is a major risk factor for heart attacks and strokes. Blood Pressure. Like regular garlic, it is a proven tool for reducing hypertension.
AGE helps with the 'clotting' risk associated with metabolic syndrome. Anti-Platelet. It prevents blood cells from sticking together, reducing the risk of thrombus (clots). It also helps improve the LDL/HDL ratio and reduces systemic inflammation markers like IL-6.
