Garlic Root Extract
Also known as: Garlic, Garlic Root Extract, *Allium sativum*
Overview
Garlic root extract, derived from the bulb of *Allium sativum*, is renowned for its extensive culinary and medicinal applications. This herbal supplement is particularly noted for its potential cardiovascular benefits, particularly in reducing blood pressure and improving lipid profiles. The active compounds in garlic, notably allicin and its derivatives, have antioxidant and anti-inflammatory properties. Research has been mixed, with a significant body of literature supporting garlic's efficacy in various health conditions, while some studies present inconclusive results. Garlic can be consumed in various forms, including raw, powdered, or as an extract, with aged garlic extract often favored for its better bioavailability and efficacy in clinical studies.
Benefits
Garlic root extract offers several evidence-based benefits: 1. **Blood Pressure Reduction**: A meta-analysis indicated aged garlic extract significantly lowers systolic blood pressure (SBP) by approximately -4.03 mmHg and diastolic blood pressure (DBP) by -1.44 mmHg, particularly at doses exceeding 1200 mg/day. 2. **Components of Metabolic Syndrome**: Garlic has shown effectiveness in decreasing triglycerides, total cholesterol, and LDL cholesterol levels. Those with metabolic syndrome may particularly benefit. 3. **Reduction in Inflammation**: Garlic supplementation has been linked to decreased C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-α), highlighting its anti-inflammatory effects.
How it works
The active components of garlic, especially allicin, play a crucial role in its health benefits. Allicin interacts with various biological pathways that enhance endothelial function, which improves blood flow and may reduce blood pressure. Additionally, garlic exhibits anti-inflammatory properties by downregulating pro-inflammatory cytokines and enhancing antioxidant defenses, thereby decreasing oxidative stress in the body.
Side effects
Garlic is generally safe for moderate consumption but can lead to several side effects. Common adverse effects include gastrointestinal discomfort and unpleasant breath odor. Uncommon reactions can include allergic responses. Rarely, there can be risks of bleeding, particularly when taken with anticoagulants, thus requiring careful consideration for individuals on such medications. Additionally, garlic may interact with certain drugs, such as blood thinners and diabetes medications, necessitating consultation with healthcare providers. Pregnant or breastfeeding women should exercise caution due to limited safety data in those populations.
Dosage
The recommended dosage of garlic root extract typically depends on the intended health benefit. For blood pressure reduction, a starting dose of 600-1200 mg/day is generally effective, with the optimal range being 1200-2400 mg/day for enhanced cardiovascular benefits. While exact upper limits are not strictly defined, high doses may increase side effect risks. It is advisable to ensure consistent daily intake for optimal effects, and aged garlic extract is recommended over raw forms due to better bioavailability and effectiveness.
