Garlic Extract
Snapshot
Garlic extract is a concentrated source of organosulfur compounds, primarily allicin, known for supporting cardiovascular health, immune function, and antioxidant defense.
What is Garlic Extract?
Garlic extract is derived from the bulbs of Allium sativum, standardized to yield high concentrations of allicin and related sulfur compounds that provide garlic’s signature health benefits without the taste or odor intensity of raw garlic.
Where It Comes From
Fresh garlic bulbs are harvested, peeled, and processed into powders or extracts. Allicin content is stabilized via enzymatic or enteric‑coating techniques to preserve activity through storage and digestion.
Key Nutrients & Compounds
The primary active compound is allicin, formed when alliin and the enzyme alliinase mix upon crushing garlic. Other important constituents include ajoene, diallyl disulfide, S‑allyl cysteine, and trace vitamins and minerals.
Health Benefits
Garlic extract supports healthy blood pressure and cholesterol levels by improving endothelial function and lipid metabolism. Its antimicrobial and immune‑modulating properties help reduce infection risk, while antioxidant effects combat oxidative stress and support detoxification pathways.
Recommended Dosage
Standardized extracts typically provide 600–1,200 mg daily, delivering 1.3%–1.6% allicin or equivalent. Divided doses with meals enhance tolerance and absorption.
How to Use It
Garlic extract is available in capsules, tablets, or oils. Take with food to minimize gastrointestinal upset. Enteric‑coated formulations reduce odor and ensure intestinal release.
Who Should Use It?
Ideal for individuals seeking cardiovascular support, enhanced immune function, or natural antibacterial activity. It benefits those with elevated blood pressure, borderline cholesterol levels, or frequent minor infections.
Possible Interactions or Cautions
Garlic may enhance effects of anticoagulant and antiplatelet medications, increasing bleeding risk. It can cause mild gastrointestinal discomfort or heartburn in sensitive individuals. Consult a healthcare provider if on prescription medications or before surgery.
Final Thoughts
Garlic extract offers a convenient, potent form of garlic’s health‑promoting compounds. When standardized and used properly, it provides comprehensive support for heart health, immunity, and antioxidant protection.
