Kyolic Reserve aged garlic extract 1.2 g/day, providing 1.2 mg/day S-allylcysteine,
does it really help with Reduction of office systolic blood pressure in uncontrolled hypertension?
research showsGrade C with 50 points. In a 12-week placebo trial, the adjusted office-SBP contrast was -5.0±2.1 mmHg (P=.016), but the manufacturer supplied capsules and research funding and the small study used protocol-related exclusions.
ads claimThe result cannot be extended to raw garlic, black garlic, all garlic powders, or cardiovascular-event prevention.
Useful facts when choosing a product
- This verdict applies only to the displayed formulation, route, dose, duration, population, endpoint, and comparator.
- Raw garlic, powder, garlic oil, stabilized-allicin products, aged garlic extract, black garlic, fermented garlic, and isolated S-allylcysteine are not interchangeable.
- Caution. Monitor for low blood pressure or dizziness with antihypertensives, and review perioperative or anticoagulant/antiplatelet use with a clinician.
Chamgap Semantic Classification Code
Permanent code issued
S.aged-garlic-extract.oral-addon.office-systolic-blood-pressure.reduce.placeboSupplements and nutraceuticals > Aged garlic extract > Oral add-on > Office systolic blood pressure > Reduction claim > Placebo plus usual care
Bound to AGE 1.2 g plus SAC 1.2 mg/day for 12 weeks and office SBP; DBP and ambulatory pressure are separate. The code identifies the intervention and claim; it never contains the evidence grade, score, or safety result.
Exact Claim Classification
These independent facets prevent evidence from different forms, routes, populations, effects, and comparators from being mixed.
| Intervention class | S · Supplement or nutraceutical |
|---|---|
| Canonical ingredient or intervention | Aged garlic extract |
| Source or part used | Allium sativum L. cloves aged in aqueous ethanol and processed as extract powder |
| Formulation or processing | Kyolic Reserve capsules; 1.2 g AGE and 1.2 mg SAC per day |
| Route | Oral add-on |
| Dose | Two capsules daily, 1.2 g AGE and 1.2 mg SAC |
| Duration | 12 weeks of treatment and follow-up |
| Population | Adults with uncontrolled hypertension on stable antihypertensive therapy or no planned medication change |
| Effect or condition | Lower office systolic blood pressure |
| Primary endpoint | Between-group change in office SBP at week 12 |
| Comparator | Matching placebo plus existing blood-pressure care |
| Duplicate-detection key | Aged garlic extract|Kyolic Reserve capsules; 1.2 g AGE and 1.2 mg SAC per day|Oral add-on|Adults with uncontrolled hypertension on stable antihypertensive therapy or no planned medication change|Lower office systolic blood pressure|12 weeks of treatment and follow-up |
What the research actually shows
The AGE at Heart paper and registry were checked against the same group's earlier dose-ranging study; a blood-pressure meta-analysis retracted in 2026 was excluded.
Why this is classified as C (50)
This is S/R1/I0 with E+ as the sole strength; fewer than 200 participants and protocol-related exclusions yield C/50.
Counterpoint. A dose-ranging study from the same group and a different aged-black-garlic product do not establish independent product-matched replication.
Rejudgment record. Independent Codex cross-check — One formulation, route, population, claim, principal endpoint, and comparator
| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I0 | Evidence comes only from manufacturer studies |
| Effect size | E+ | Meets the clinically important threshold |
| Precision | CX | No pooled confidence interval could be confirmed |
The scoring table and the verdict agree (C).
