What it is & primary uses
A culinary allium available as food, powder, oil or aged extract, with preparation-dependent active compounds.
Main benefits
- Some meta-analyses report small blood-pressure and LDL reductions.
- Preparations are not equivalent and hard cardiovascular outcomes are unproven.
Studied protocols
Research doses are grouped by outcome. They describe study designs—not a personal prescription.
600–1,200 mg/day aged or standardized garlic extract
- Study duration
- Commonly 4–12 weeks; protocol and outcome vary
- Interpretation
- Preparations are not equivalent and hard cardiovascular outcomes are unproven.
04Food sources & equivalents＋
Can food provide a studied amount?
Fresh garlic can provide related dietary exposure, but food and extract milligrams are not automatically interchangeable.
Dietary exposure; verify composition before comparing with a studied supplement dose
- How this was estimated
- Dose Radar compares the declared active ingredient with official composition data or the studied standardized extract—not with marketing names.
- Important limitation
- Natural content, preparation, bioavailability and formulation vary. This comparison does not prove equal physiological effect.
Food equivalents compare ingredient mass using published composition values. They do not prove equal absorption, formulation, physiological effect, safety or personal need.

With food
Food commonly improves gastrointestinal tolerance, although it can change absorption for some ingredients.
- Practical approach
- With food, divided. Keep the formulation and daily total consistent with the evidence context shown above.
- Watch for
- Anticoagulants
Meal guidance reflects human pharmacokinetic, clinical, official-label or evidence-review sources where available. A food pairing can change absorption or tolerability, but does not make a supplement necessary, effective or safe for every person.

An unlisted pair means no established pair-specific interaction was identified in this review—not proof that every dose, product or person is safe.
This is not proof that every dose, product or user context is safe. Medication and condition checks still apply.
07Research notes＋
Moderate evidence for the stated context. Preparations are not equivalent and hard cardiovascular outcomes are unproven.
The displayed amount comes from human research or an official evidence summary. It is not a personalized prescription, and formulation can change whether the comparison is valid.
08Scientific references＋
Peer-reviewed human research and formal evidence reviews. Open each source to inspect the complete paper record.

Dose context: Ingredient-specific human literature; dose and formulation vary
This live index supports source verification. A new paper does not change the Dose Radar grade until its design, population and formulation are reviewed.
09Expert & media references＋
Podcast and practitioner statements are clearly separated from research. They may explain practice or emerging ideas, but do not prove efficacy.
