Aged Garlic Extract
Aged Garlic Extract (Kyolic)
Odorless garlic extract with strong evidence for cardiovascular health, blood pressure, and immune support.
Aged Garlic Extract (AGE) is produced by aging raw garlic in a controlled process that converts harsh compounds into beneficial ones like S-allyl cysteine. Unlike raw garlic, it's odorless and gentler on the stomach. Strong clinical evidence supports benefits for blood pressure, cholesterol, arterial stiffness, and immune function.
Mechanisms of Action
Vasodilation
Relaxes blood vessels to lower blood pressure
Antioxidant Protection
Protects against oxidative damage
Lipid Modulation
May improve cholesterol profile
Recommended Dose
600-1200mg aged garlic extract

Saadh MJ et al. • Prostaglandins & other lipid mediators (2024)
“The results of this study suggest that AGE supplements may be beneficial for improving blood pressure in hypertensive patients, but significant effects are observed only at doses over 1200 mg/day.”
Key Findings:
- AGE tea supplementation reduces systolic blood pressure (SBP) (WMD: -4.03; %95CI: -6.87, -1.20; I2: 57.1 %) and diastolic blood pressure (DBP) (WMD: -1.44; 95 % CI= -2.87, -0.02; P = 0.052; I2: 36.8 %; P: 0.105).
- Moreover, subgroup analysis indicated that higher doses of AGE supplementation in hypertensive patients significantly decreased DBP, and SBP.
- The results of this study suggest that AGE supplements may be beneficial for improving blood pressure in hypertensive patients, but significant effects are observed only at doses over 1200 mg/day.
- To confirm these results, well-designed future trials will be needed.

“However, garlic could be considered a safe natural medicine to debilitate inflammation in CAD patients.© 2023 John Wiley & Sons Ltd.”
Key Findings:
- The standardized mean difference with 95% CI was calculated using fixed-effect or random-effect models.
- In the case of subgroup analysis, the overall effect was significantly effective in reducing TC, LDL levels and improving HDL levels in CV risk patients.
- Our study findings provide consistent evidence that intake of garlic reduces CVD risk factors.

Zeng T et al. • Journal of the science of food and agriculture (2012)
“Garlic could reduce serum TC and TG levels, and garlic therapy should benefit patients with risk of cardiovascular diseases.”
Key Findings:
- Compared with the placebo groups, serum TC and TG levels in the garlic group were reduced by 0.28 (95% CI, -0.45, -0.11) mmol L⁻¹ (P = 0.001) and 0.13 (95% CI, -0.20, -0.06) mmol L⁻¹ (P < 0.001), respectively.
- Garlic could reduce serum TC and TG levels, and garlic therapy should benefit patients with risk of cardiovascular diseases.
- Further research warranted to confirm findings
Zhang L et al. • The American journal of clinical nutrition (2006)
“In this rural Chinese population with low meat intake and moderate cholesterol concentrations, long-term garlic supplementation had no effect on lipid profiles, whereas micronutrient supplementation was associated with small but significant increases in total and LDL-cholesterol concentrations at 7.3 y.”
Key Findings:
- Regressions adjusted for covariates indicated increases of 0.22 mmol total cholesterol/L (P = 0.01) and 0.19 mmol LDL/L (P = 0.02) after 7.3 y of micronutrient supplementation, but no effect of garlic supplementation or short-term amoxicillin and omeprazole treatment.

- Further research warranted to confirm findings
Serrano JCE et al. • Nutrients (2023)
“It was concluded that low-dose SAC supplementation in an optimized black-garlic extract allows for an extra-significant reduction in blood pressure in a Grade I hypertensive population receiving drug treatment.”
Key Findings:
- A reduction in systolic and diastolic blood pressure of 1.8 mmHg (0.7 to 4.1 95% CI) and 1.5 mmHg (0.3 to 3.0 95% CI), respectively, was observed.
- It was concluded that low-dose SAC supplementation in an optimized black-garlic extract allows for an extra-significant reduction in blood pressure in a Grade I hypertensive population receiving drug treatment.
- No changes in endothelial function and inflammatory cytokines were observed.
