Garlic

Immune Support
Garlic and aged garlic extract (AGE) has been shown to help improve immune cell function and reduce the severity of infections like colds and flus (1). 

In addition to boosting general immune function, studies suggest that garlic has strong anti-cancer properties. Garlic works to protect against cancer by reducing free radicals, increasing glutathione, repairing DNA, and preventing chromosomal damage, among others (2).


Reduces Inflammation
Studies show that aged garlic extract (AGE) can modulate immune cell distribution and increase serum levels of inflammation-fighting TNF-α and IL-6 (3). This may help reduce the development of low-grade inflammatory chronic diseases, especially related to obesity. 

 

Allergy Support
Aged garlic extract (AGE) has shown potential anti-allergic effects. Studies show that AGE can  reduces the body’s allergic responses by modifying the function of immune cells, specifically altering the function of mast cells, basophils, and T lymphocytes to reduce the allergic cascade and inflammatory response (4). 


Respiratory Support
Garlic could reduce viral infections in the upper respiratory tract, including the common cold (5). Studies suggest that garlic has antiviral effects and can specifically help reduce the risk of conditions like lung cancer (6, 7).

Gut Health Support
Garlic helps to support gut health by improving the composition of the gut microbiome (8). Studies suggest this may be specifically helpful to improve health and gut function in those with high-fat diets, as garlic also improves gut dyslipidemia (9).

Heart Support
Garlic has been shown to improve cardiovascular function and reduce risk of cardiovascular disease. One study suggests that garlic can reduce serum cholesterol (10). Others show that garlic supplementation reduces blood pressure in those with hypertension (11). 

Studies also show that garlic has hypoglycemic effects and can reduce fasting blood sugar levels (12).


Energy Support
Garlic has been shown to increase exercise endurance and improve fatigue, whether related to physical exertion, fatigue from illness, or general tiredness from an unknown cause (13). 

Why garlic helps fatigue is still being studied, but some research points to garlic’s ability to reduce oxidative stress, facilitate glucose metabolism, and enhance oxygenation in muscles as the mechanisms of action (14).

Mood Support
Low-temperature aged garlic (LTAG) and raw garlic have been shown to reduce acute stress and may moderate depression by decreasing stress hormones such as cortisol, corticotropin-releasing factor, and corticosterone (15).


Sleep Support
The anti-inflammatory effect of garlic has been recommended to help improve sleep in those with conditions like sleep apnea (16).
