What Does the Latest Science Say About Kyolic Aged Garlic Extract?

Kyolic Aged Garlic Extract is produced through a proprietary 20-month aging process that transforms the harsh, volatile compounds in raw garlic into stable, highly bioavailable ones with remarkably wide-ranging health benefits. Wondering if Kyolic Aged Garlic Extract is right for you? Check out the latest evidence to understand why it may warrant a place in your daily routine.

Cardiovascular health

Research has repeatedly found that Aged Garlic Extract (AGE) supports cardiovascular health in numerous ways. For instance, a 2024 randomized, double-blind, placebo-controlled study that appeared in the Journal of Functional Foods found that supplementing with 1.2g of Aged Garlic Extract powder daily decreased systolic blood pressure by 18.6 mmHg after four weeks and 18.1 mmHg after 12 weeks in people with high blood pressure. Diastolic blood pressure dropped by 10.6 mmHg at week four. In addition, AGE improved stool consistency, glycemic parameters, and LDL cholesterol.¹*

An earlier analysis of 12 clinical trials involving 553 people with hypertension reported that Aged Garlic Extract lowered systolic blood pressure by an average of 8.3 mmHg and diastolic blood pressure by 5.5 mmHg, which is similar to standard blood pressure medication. The meta-analysis concluded that these changes translated to a 16-40 percent reduction in the risk of suffering from a heart attack or other cardiovascular event.² *

Another 2025 study in the journal Experimental and Therapeutic Medicine reviewed the therapeutic effects of Aged Garlic Extract (AGE) on atherosclerosis—an artery-narrowing condition affecting up to 75 percent of all Americans over the age of 60. It reported that AGE works on multiple fronts to reduce the risk of this artery-clogging disease. In addition to lowering blood pressure, the actions of AGE include suppressing chronic inflammation, reducing total cholesterol, inhibiting the formation of calcified plaque, and activating endothelial nitric oxide.³ An earlier study documented the ability of AGE to increase arterial elasticity in people with high blood pressure.⁴ Together these actions may improve endothelial function and reduce the risk of atherosclerosis.*

Immunity

Building a strong immune system is critical for guarding against both seasonal pathogens and chronic, more serious, diseases. A rich source of bioactive compounds, studies show that Aged Garlic Extract supplementation fortifies the immune system by enhancing the function of T-cells and Natural Killer (NK) cells, stimulating key cytokines, and preventing the suppression of the body’s immune response.⁵ The real-world benefits of these actions was shown in a 2016 clinical trial involving 120 healthy volunteers. Compared to those taking a placebo, the volunteers consuming 2.56 g of AGE daily for 45–90 days experienced improve immune function and a reduction in the severity and duration of colds and flu.⁶*

More recent research reports that Aged Garlic Extract protects against chronic illness thanks to its antioxidant and anti-inflammatory properties and its ability to modify the gut microbiome. This, in turn, reduces oxidative stress and enhances gut-derived immunity.⁷  *

Cognition and memory

Aged Garlic Extract also shows promise for cognitive health, primarily through its neuroprotective, antioxidant, and anti-inflammatory properties. Recent research suggests its potential for enhancing global cognition and reducing cardiovascular risk factors associated with dementia. While many studies are preclinical, some emerging human data indicates AGE may improve memory and reduce cognitive decline, particularly in older adults. ⁸ *

Gut health

Emerging evidence suggests that Aged Garlic Extract, which acts like a prebiotic, improves the gut microbiota by increasing the richness and diversity of beneficial bacteria like Lactobacillus and Clostridia after just three months of supplementation. According to this 2018 randomized, placebo-controlled clinical trial, these changes may also help activate innate immunity in the gut.⁹ While more human investigation into the impact of AGE on gut health is needed, preclinical research conducted in 2025 has found that it might improve dysmotility in older adults.¹⁰ Dysmotility— problems with the muscles in your GI tract that contract to move food through your digestive system—is common in the elderly and may lead to muscle loss (sarcopenia) and frailty.*

Aerobic fitness

It’s no secret that exercise is good for you. In fact, study after study clearly shows that getting regular aerobic exercise can significantly improve your cardiovascular health by boosting something called VO₂ max (the maximum amount of oxygen your body can absorb and use during intense exercise and a marker of aerobic fitness).¹¹ Research shows that pairing those aerobic workouts with Aged Garlic Extract can improve your aerobic fitness and performance even more. In a 2025 double-blind, placebo-controlled, randomized study involving 75 middle-aged recreational endurance athletes, supplementing with AGE was found to increase VO₂ max and arterial flexibility, while decreasing fatigue and reducing post-workout recovery time. These benefits weren’t seen in those taking the placebo.¹² *

Oral health

Periodontal disease—a serious infection that can destroy the gums, ligaments, and bone supporting the teeth—is a common condition affecting up to 60 percent of adults.¹³ Aged Garlic Extract has been shown to reduce both the incidence and the symptoms of periodontal disease thanks to its antioxidant and anti-inflammatory properties.¹⁴ One 2023 study review published in the Journal of Indian Association of Public Health Dentistry found that AGE inhibits the buildup of plaque and improves gum healing.¹⁵ *

These studies, along with earlier scientific research, confirms the many benefits authentic Kyolic Aged Garlic Extract provides. These benefits range from improved blood pressure and overall cardiovascular health to immunity, aerobic fitness, and oral health.* Preclinical studies into the impact of Kyolic AGE on brain and gut health are also promising. What’s more, clinical trials show that Kyolic Aged Garlic Extract is extremely safe and well-tolerated in most people, making it ideal for daily use. Of course, it’s always a good idea to check with your healthcare provider before adding any new supplement, especially if you are pregnant, nursing, or taking medication for a chronic illness. Share these studies with your provider and see if they agree that Kyolic Aged Garlic Extract is a good choice to support your wellness journey.
