Little is known about the combined effects of ginger and garlic on inflammation in humans. However, based on the available research, it’s likely that using garlic and ginger together could help reduce markers of inflammation.

Summary: Studies show that garlic and ginger both separately offer potent anti-inflammatory effects. Based on results from clinical research, it’s likely that combining garlic and ginger would offer anti-inflammatory benefits.

2. Garlic and ginger may protect against cellular damage

Oxidative stress occurs when an overload of molecules called reactive oxygen species (ROS) overwhelms your body’s defenses.

The body’s antioxidant defense system includes antioxidant enzymes, such as superoxide dismutase and glutathione peroxidase. These help keep the level of ROS in balance. However, when this system is overwhelmed, oxidative stress occurs, which leads to cellular damage.

Studies show garlic and ginger may help reduce oxidative stress markers, including the highly reactive and damaging compound malondialdehyde.

A 2015 study gave people with type 2 diabetes 2 grams of ginger powder daily for 12 weeks. At the end of this treatment, they had significantly reduced blood levels of malondialdehyde compared with a control group.

A 2016 study showed that taking ginger supplements reduced levels of malondialdehyde and the inflammatory marker TNF-α in people with tuberculosis.

A 2008 study in 13 older people found that taking garlic supplements daily for 1 month decreased malondialdehyde levels and boosted levels of the antioxidant enzymes superoxide dismutase and glutathione peroxidase.

What’s more, a 2020 study in rats with Alzheimer’s disease demonstrated that combined treatment with garlic, ginger, and chili pepper extract significantly increased levels of the defense enzymes superoxide dismutase and glutathione peroxidase.

It also significantly decreased levels of the damaging compound malondialdehyde.

Summary: Studies in humans and rodents show that garlic and ginger may help reduce markers of oxidative stress and may help boost antioxidant defenses.

3. Garlic and ginger may benefit cognitive health

Regularly consuming garlic and ginger or taking garlic and ginger supplements may help protect your brain and improve cognition.

Some population studies have suggested that consuming garlic may be particularly helpful for protecting against cognitive impairment in certain populations.

A 2019 population study that included 27,437 older Chinese people found that those who consumed garlic more frequently were less likely to experience cognitive impairment. They also lived longer than those who rarely consumed garlic.

Scientists need to do more studies on this phenomenon, including research on other groups of people.

Studies have shown that taking garlic powder may improve memory and attention in healthy adults.

Research suggests the organosulfur compounds in garlic may help protect against nerve cell inflammation and degeneration.

Research has also linked ginger to cognitive benefits. In a 2011 study, taking 400 or 800 mg of ginger extract daily for 2 months helped improve cognitive performance and memory in healthy women, compared with a placebo.

Additionally, animal studies suggest that taking ginger may help decrease brain damage, protect against neurodegenerative disease, and increase levels of antioxidant enzymes in the brain.

Summary: Ginger and garlic may benefit brain health by protecting against cognitive decline and improving cognitive function.

4. Garlic and ginger may reduce heart disease risk factors

Studies have shown that garlic and ginger have strong heart-protective properties and may help decrease some risk factors of heart disease, including:

A 2014 review of 22 high-quality studies found that consuming garlic powder significantly reduced levels of total and LDL (bad) cholesterol and fasting blood sugar and blood pressure levels.

Other studies have shown that garlic helps reduce blood pressure, blood sugar, and cholesterol and helps prevent atherosclerosis or plaque buildup in the arteries.

Studies have also linked ginger to heart health benefits.

A 2017 study including 4,628 participants found that consuming 1 gram of ginger daily decreased people’s risk of high blood pressure and coronary heart disease by 8% and 13%, respectively.

Ginger supplements may also help improve blood sugar control and reduce levels of triglycerides, total cholesterol, and inflammatory markers in people with diabetes. This is significant because people with diabetes have an increased risk of heart disease.

Therefore, consuming garlic and ginger regularly or taking garlic and ginger supplements may help you promote heart health.

However, you should check with a healthcare professional before taking high-dose garlic and ginger supplements because they may interact with certain medications. These include blood thinners, which healthcare professionals use to treat heart disease.

Summary: Studies show that ginger and garlic may help reduce heart disease risk factors like high blood pressure and high blood lipid levels and help protect against heart disease.

5. Garlic and ginger may be beneficial for those with diabetes

Garlic and ginger may help reduce blood sugar levels and improve other health markers in people with diabetes, especially if you take them in supplement form.

A 2020 study of 103 people with type 2 diabetes gave participants 1.2 grams of ginger supplements daily for 90 days. Those who took it experienced a greater reduction in blood sugar and total cholesterol levels than those who took a placebo.
