Garlic Extract Oil
Also known as: Allium sativum, Garlic Oil, Aged Garlic Extract, Garlic Supplement, Garlic Extract Oil
Overview
Garlic (*Allium sativum*) is a prominent member of the Allium family, well-known for its culinary applications and numerous medicinal properties. In oil form, garlic extract oil is rich in bioactive compounds, notably allicin, which contributes to various health benefits. Research has shown that garlic extract oil can support cardiovascular health, enhance glycemic control, and provide anti-inflammatory effects. Commonly consumed in forms such as oils, capsules, and powders, garlic extract oil allows for flexible intake tailored to user preferences. A comprehensive body of systematic reviews corroborates the therapeutic efficacy and safety of garlic and its extracts, affirming their role in health improvement across multiple contexts.
Benefits
Garlic supplementation is linked to substantial improvements in metabolic and cardiovascular health. Meta-analyses indicate that garlic significantly lowers fasting blood glucose levels (mean reduction: -7.01 mg/dL) and HbA1c (-0.66%). It also effectively reduces total and LDL cholesterol levels, with mean declines of -14.17 mg/dL and -8.20 mg/dL, respectively. Hypertensive patients particularly benefit, showing reductions in systolic (-4.03 mmHg) and diastolic pressures (-1.44 mmHg) with aged garlic extract. Additionally, garlic's anti-inflammatory properties, evidenced by lower C-reactive protein levels, are beneficial for individuals facing cardiovascular issues, hyperlipidemia, or type 2 diabetes mellitus.
How it works
The therapeutic effects of garlic largely stem from its active components, especially allicin. Allicin is known to inhibit HMG-CoA reductase, a crucial enzyme in cholesterol synthesis, thus aiding in lipid reduction. Furthermore, garlic promotes insulin sensitivity and enhances glucose metabolism, contributing to cardiovascular health. Its anti-inflammatory actions are characterized by reduced levels of inflammatory markers such as C-reactive protein and TNF-α. The bioavailability of these active compounds can vary significantly depending on the preparation, with aged garlic extract showing superior absorption characteristics over raw garlic.
Side effects
Garlic supplementation is generally well tolerated, although some users may experience gastrointestinal issues such as bloating, gas, and diarrhea, which can affect more than 5% of individuals. Allergic reactions to garlic are rare but can occur, manifesting as skin rashes or respiratory difficulties. Other common side effects, which are usually benign, include halitosis and body odor. Caution should be exercised for those on anticoagulant medications like warfarin, as garlic may increase bleeding risks. It is advisable to cease garlic supplementation at least two weeks before any surgical procedures to reduce complications. Pregnant and breastfeeding women should consult healthcare providers before using garlic, particularly those with pre-existing gastrointestinal concerns.
Dosage
For effective supplementation, a minimum of 600-900 mg daily of aged garlic extract (AGE) is typically recommended. For enhanced improvements in lipid profiles and blood pressure, an intake of approximately 1200 mg/day of AGE is advisable. While a definitive upper limit for safe consumption has not been established, exceeding 2400 mg/day may elevate the risk of adverse effects. To minimize potential gastrointestinal discomfort, it is advisable to take garlic supplements during meals. Aged garlic extract is preferred for its enhanced bioavailability; however, garlic oil remains effective when sourced from reputable manufacturers, especially when consumed alongside fatty foods to improve absorption.
