Garlic
SaveA sulfur-rich bulb with some of the strongest herb data for cardiovascular and immune support.
Quick verdict
Garlic is one of the most evidence-backed culinary herbs, especially for blood pressure and modest lipid support.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Meta-analyses show modest reductions in blood pressure and lipids, with additional evidence for immune and vascular support. Allicin potential depends heavily on preparation and freshness.
Benefits
- May modestly reduce blood pressure
- Provides antimicrobial sulfur compounds
- Supports vascular and immune health
Dosage notes
Typical supplemental use ranges from 600-1200 mg/day of aged extract or powder; culinary use remains valuable.
Side effects
- Reflux
- Garlic odor
- Increased bleeding tendency
Who should be cautious
Can increase bleeding risk and cause substantial reflux or odor. High doses may interact with anticoagulants and antiplatelet drugs.
What this page cannot tell you
Aged extract, powder, oil, and fresh garlic are not interchangeable, and allicin yield varies dramatically.
