Can Garlic Reduce Cholesterol Naturally? Know What a Dietitian Says

Garlic has long been valued as both a cooking ingredient and a traditional home remedy. From boosting flavour in meals to being praised for its health benefits, garlic has earned a reputation as a natural way to support heart health. One of the most common claims is that it can lower cholesterol.

But how true is this claim? Can eating garlic really reduce cholesterol naturally, or is it simply a popular myth?

According to the British Heart Foundation, garlic may have a positive effect on cholesterol, but the benefits are modest. While it can be a healthy addition to your diet, it should not replace prescribed medication or other proven lifestyle measures for managing high cholesterol.

Why Is Garlic Considered Good For Heart Health?

Garlic contains several natural compounds, including one called allicin, which is formed when fresh garlic is crushed or chopped.

These compounds have antioxidant and anti-inflammatory properties that may help protect blood vessels from damage. Researchers believe they may also influence the way the body produces and processes cholesterol.

Because inflammation and oxidative stress contribute to cardiovascular disease, foods that help reduce these processes may support overall heart health.

Can Garlic Really Lower Cholesterol?

According to Dr Archana Batra, Dietitian and Certified Diabetes Educator, “Garlic may produce a modest reduction in total cholesterol and LDL cholesterol when consumed regularly. However, the effect is generally small. This means garlic alone is unlikely to bring cholesterol down to healthy levels if it is significantly raised.”

The benefits seen in studies are usually greater when garlic is combined with other healthy lifestyle habits, such as eating a balanced diet, exercising regularly, and maintaining a healthy weight.

How Much Garlic Should You Eat?

There is no official recommendation for the amount of garlic needed to lower cholesterol.

Many studies have used fresh garlic or garlic extracts over several weeks or months. A 2024 review published in the journal ‘Frontiers in Nutrition’ suggests consumption of 10 grams of garlic per day for two months to avail cholesterol-lowering benefits.

However, eating more garlic does not necessarily produce better results.

Including one or two cloves of fresh garlic in your daily cooking is a practical and healthy way to enjoy its flavour and potential benefits.

It is important to remember that garlic works best as part of an overall healthy eating pattern rather than as a single remedy.

Is Raw Garlic Better Than Cooked Garlic?

Some people believe that raw garlic is much more effective than cooked garlic because heating can reduce the amount of allicin, the compound linked to many of its health benefits.

According to Dr Batra, while raw garlic may contain higher levels of certain active compounds, cooked garlic still provides valuable nutrients and beneficial plant compounds.

Whether eaten raw or cooked, garlic can be included as part of a balanced diet. The most important factor is consuming it regularly in sensible amounts.

Can Garlic Replace Cholesterol-Lowering Medicines?

The simple answer is no.

Dr Batra emphasises that garlic should not be considered a substitute for prescribed cholesterol-lowering medications or comprehensive lifestyle changes, even though it can be part of a heart-healthy eating pattern.

People with high cholesterol, especially those at increased risk of heart disease, may need medicines such as statins to lower LDL cholesterol effectively.

Stopping medication and relying only on garlic could increase the risk of serious complications, including heart attack and stroke.

NOTE: Always follow your doctor's advice regarding treatment.

Are Garlic Supplements Effective?

Garlic supplements are widely available, but their quality and effectiveness can vary.

Different supplements contain different amounts of active compounds, making it difficult to know how much benefit they provide.

Some garlic supplements may also interact with medicines, especially blood thinners, increasing the risk of bleeding.

For most people, eating fresh garlic as part of everyday meals is a safer and more natural option.

If you are considering garlic supplements, speak to your healthcare provider first.

Who Should Avoid Garlic?

Although garlic is safe for most people when used in cooking, some individuals should be cautious. Large amounts of garlic may cause:

• Heartburn
• Stomach discomfort
• Bad breath
• Digestive upset

People taking blood-thinning medicines or preparing for surgery should consult their doctor before using large amounts of garlic or garlic supplements because they may increase the risk of bleeding.

Your cholesterol levels are influenced by many factors, including genetics, age, physical activity, body weight, medical conditions and your overall eating pattern.

Focusing on one ingredient while ignoring other aspects of health is unlikely to produce lasting results. Instead, aim to build healthy habits that you can maintain over time.

Final Word

Garlic is a nutritious ingredient that offers several potential health benefits. Research suggests it may produce a modest reduction in total cholesterol and LDL cholesterol when eaten regularly, thanks to its natural antioxidant and anti-inflammatory compounds. However, as Dr Archana Batra points out, the effect is generally small. The best approach is to include garlic as part of a balanced, heart-healthy diet.
