Alliàge™ (Aged Garlic Extract — S-Allylcysteine)

Allium sativum
Evidence Level
Limited
2 Clinical Trials
3 Documented Benefits
2/5 Evidence Score

Alliàge™ is a branded aged garlic extract from Vidya Herbs standardized to S-allylcysteine (SAC), marketed for men's hormonal and sexual wellbeing. Aged garlic itself has good evidence for modest cardiovascular benefits: large meta-analyses of randomized trials show small reductions in blood pressure and cholesterol. That evidence is for garlic generally, not for Alliàge specifically. Honest framing: Alliàge's strongest evidence is the cardiometabolic aged-garlic literature; its specific men's-health branded trial is not PubMed-indexed, so that particular claim is less established.

Studied Dose Manufacturer trial: 200 mg/day for 60 days. Aged garlic cardiovascular trials typically use higher SAC-standardized doses.
Active Compound Aged garlic (Allium sativum) extract standardized to S-allylcysteine (SAC). Alliàge™ is manufactured by Vidya Herbs.

Benefits

Cardiovascular support (well-evidenced)

Garlic and aged garlic extract modestly lower blood pressure and improve some cholesterol markers. A large 2026 meta-analysis of 108 randomized trials in about 7,100 people found average reductions of roughly 3.7 mmHg systolic and 2.0 mmHg diastolic blood pressure, plus small drops in total and LDL cholesterol. This evidence is for garlic in general, not for Alliàge specifically, which has no published trial of its own.

Supported by Trial 1

Men's hormonal / sexual wellbeing (manufacturer claim)

The manufacturer (Vidya) reports a placebo-controlled trial in men with low-testosterone symptoms showing improved symptom and erectile-function scores, but this trial is unpublished and not indexed in PubMed, so it cannot be independently verified. Treat it as manufacturer data only. The broader human evidence for garlic raising testosterone is limited. Erectile difficulty is a medical issue that warrants seeing a doctor rather than self-treating with a supplement.

Supported by Trial 2

Antioxidant support

S-allylcysteine is a stable, bioavailable antioxidant that contributes to aged garlic's vascular and general antioxidant benefits.

Supported by Trial 1

Mechanism of action

1

Nitric oxide / vascular effects

Aged garlic supports nitric-oxide-mediated vasodilation and reduces arterial stiffness, lowering blood pressure.

2

Antioxidant S-allylcysteine

SAC scavenges reactive oxygen species and supports endothelial function, the basis for the cardiovascular and general antioxidant effects.

Clinical trials

1
Aged garlic cardiovascular evidence

Systematic reviews and meta-analyses of aged garlic extract / garlic supplementation.

Hypertensive and at-risk adults

A 2026 meta-analysis of 108 randomized trials (about 7,100 people) found garlic lowered blood pressure by roughly 3.7 mmHg systolic and 2.0 mmHg diastolic and slightly reduced total and LDL cholesterol. This is evidence for garlic generally, not for Alliàge itself.

2
Branded Alliàge Men's-Health Trial (manufacturer)

Randomized, double-blind, placebo-controlled, n=52 men, 200 mg/day for 60 days. Not PubMed-indexed.

Men 25–60 with low-testosterone symptoms

Manufacturer reports improved symptom (AMS) and erectile-function (IIEF) scores. Treat as manufacturer evidence; the testosterone claim is not independently established.

Side effects and drug interactions

Common Potential side effects

Generally well tolerated; aged garlic is gentler on the stomach than raw garlic.
Garlic breath/body odor is reduced versus raw garlic but can still occur.
Mild gastrointestinal upset possible.
May add to blood-thinning — relevant around surgery.

Important Drug interactions

Anticoagulants/antiplatelets (warfarin, aspirin): garlic has antiplatelet activity — additive bleeding risk; stop before surgery.
Antihypertensives: possible additive blood-pressure lowering.
Some HIV protease inhibitors (e.g., saquinavir): garlic can reduce drug levels — avoid combining.
