Swanson OdorlessGarlic is an effective way to get the benefits of garlic without the unpleasant odor that accompanies many garlic supplements. Each capsule provides 500 mg of garlic with a potency of 10,000 ppm allicin to support cardiovascular health without the lingering odor on your breath. The allicin in garlic may also support the immune system by producing more natural killer (NK) cells in the blood. Garlic supplementation reduces circulating markers of oxidative stress (e.g., malondialdehyde) and inflammation (e.g., C-reactive protein and TNF-alpha). Garlic supplementation may also reduce total cholesterol levels, especially in people with cardiovascular disease, and improve other markers of cardiovascular health (coronary artery calcium, carotid intima-media thickness, etc.).
