10 Surprising Benefits of Olive Oil and Lemon Juice

Did you know that ancient Greeks consumed olive oil daily not just as food but as medicine? This centuries-old practice of drinking olive oil combined with lemon juice has steadily gained popularity in modern wellness circles—and for good reason. The powerful combination of heart-healthy fats from olive oil and vitamin-rich citrus creates a simple yet potent elixir that supports multiple body systems.

In this post, you’ll learn 10 surprising ways this simple morning drink can boost your health, backed by scientific research and practical advice for incorporating it into your daily routine. From digestive health to glowing skin, drinking olive oil and lemon juice offers benefits that might just transform your wellness routine.

What Is “Drinking Olive Oil and Lemon Juice”?

Drinking olive oil and lemon juice is a traditional Mediterranean health practice that involves consuming a small amount of extra virgin olive oil mixed with freshly squeezed lemon juice, typically on an empty stomach in the morning. This remedy has roots in Greek, Italian, and Spanish folk medicine, where olive oil has been revered for its therapeutic properties for thousands of years.

The practice is elegantly simple: combine one tablespoon of high-quality extra virgin olive oil with the juice of half a fresh lemon, consume it straight, and follow with a glass of warm water. While this might sound unusual to those unfamiliar with Mediterranean wellness traditions, the combination offers a powerful nutritional punch that supports whole-body health.

Nutritional Synergy

What makes drinking olive oil and lemon juice particularly effective is the synergistic relationship between these two ingredients:

Olive Oil provides:

• Monounsaturated fatty acids (primarily oleic acid)
• Polyphenols and antioxidants (including oleocanthal, oleuropein)
• Vitamins E and K
• Anti-inflammatory compounds

Lemon Juice contributes:

• Vitamin C (ascorbic acid)
• Citric acid
• Flavonoids
• Potassium
• Antioxidants

When combined, these ingredients create a powerful synergy. The fat in olive oil helps your body absorb the fat-soluble vitamins and antioxidants in both ingredients. Meanwhile, the acidity from lemon juice aids digestion and helps release bile from the liver, which assists in fat digestion and absorption of the olive oil’s nutrients.

10 Surprising Health Benefits

Benefit 1: Supports Digestive Health

Drinking olive oil and lemon juice first thing in the morning can kickstart your digestive system in multiple ways. The combination works as a gentle, natural laxative that helps relieve constipation and promotes regular bowel movements.

The olive oil coats the lining of your digestive tract, reducing irritation and inflammation, while lemon juice stimulates bile production in the liver, which helps break down fats and improves digestion. A study published in the Journal of Nutritional Science found that olive oil consumption improved gut microbiota diversity, which is essential for optimal digestive health.

Research from the University of Naples has shown that olive oil’s oleic acid can reduce inflammation in digestive conditions and may help prevent or manage irritable bowel syndrome symptoms.

Benefit 2: Boosts Immune Function

The vitamin C content in lemon juice is well-known for supporting immune system function, but what many don’t realize is how olive oil enhances this benefit. The combination of vitamin C from lemons and the antioxidants in olive oil creates a powerful immunity-boosting mixture.

Olive oil contains oleocanthal, which has similar anti-inflammatory effects to ibuprofen, helping your body fight infections. Meanwhile, lemon’s vitamin C supports white blood cell production and function—your body’s first line of defense against pathogens.

Regular consumption of this mixture has been associated with fewer seasonal illnesses and faster recovery times when sickness does occur, according to research published in Frontiers in Immunology.

Benefit 3: Promotes Heart Health

One of the most well-documented benefits of drinking olive oil and lemon juice relates to cardiovascular health. Extra virgin olive oil is a cornerstone of the Mediterranean diet, which is consistently ranked as one of the healthiest dietary patterns for heart health.

The monounsaturated fats in olive oil help reduce LDL (bad) cholesterol while maintaining or increasing HDL (good) cholesterol levels. Additionally, olive oil’s polyphenols have been shown to improve endothelial function—how well the inner lining of blood vessels functions.

Meanwhile, the potassium in lemons helps maintain healthy blood pressure levels, and citrus flavonoids improve blood vessel function. A landmark study in the New England Journal of Medicine found that people who regularly consumed olive oil had a significantly lower risk of cardiovascular events than those who didn’t.

Benefit 4: Aids in Detoxification

While “detox” has become a buzzword, the olive oil and lemon juice combination genuinely supports your body’s natural detoxification processes. Lemon juice acts as a diuretic, helping flush toxins through increased urination, while also stimulating liver enzyme function.

The liver is your primary detoxification organ, and olive oil helps trigger the release of bile, which carries toxins to be excreted. This natural flush helps cleanse your system without harsh chemicals or extreme measures.

Studies from the World Journal of Gastroenterology suggest that olive oil may help prevent fatty liver disease, keeping this vital detoxification organ functioning optimally.

Benefit 5: Enhances Skin Radiance

Looking for that natural glow? Drinking olive oil and lemon juice might be your answer. This combination provides essential nutrients that promote skin health from the inside out.

Olive oil’s vitamin E and antioxidants help protect skin cells from oxidative damage, while its healthy fats help maintain skin elasticity and moisture. Lemon’s vitamin C is crucial for collagen production—the protein responsible for skin’s firmness.

Dermatological research published in the Journal of Dermatological Science shows that both topical and internal consumption of olive oil can improve skin barrier function and reduce signs of aging.

Benefit 6: Balances Blood Sugar

For those concerned about blood sugar management, the olive oil and lemon juice combination offers surprising benefits. Olive oil is comprised of primarily monounsaturated fats, which don’t trigger blood sugar spikes and can actually improve insulin sensitivity when replacing saturated fats in the diet.

Research published in Diabetes Care found that adding olive oil to meals resulted in lower post-meal blood sugar levels compared to meals with other types of fat. The acetic acid in lemon juice has been shown to slow carbohydrate digestion, further helping to prevent blood glucose spikes.

This makes drinking olive oil and lemon juice potentially beneficial for those with insulin resistance or at risk for type 2 diabetes.

Benefit 7: Helps with Weight Management

It might seem counterintuitive that consuming olive oil—a calorie-dense fat—could help with weight management, but research suggests otherwise. The monounsaturated fats in olive oil promote satiety, helping you feel fuller longer and potentially reducing overall calorie intake throughout the day.

A study published in the European Journal of Nutrition found that olive oil increased the release of hormones that signal fullness. When combined with lemon juice, which can temporarily boost metabolism through its thermogenic effect, this drink may support weight management efforts as part of a balanced diet.

Some research suggests that starting the day with olive oil and lemon juice helps reduce cravings and stabilize blood sugar, preventing the energy crashes that often lead to unhealthy snacking.

Benefit 8: Reduces Inflammation

Chronic inflammation is at the root of many modern diseases, from arthritis to diabetes and even cancer. Both olive oil and lemon juice contain potent anti-inflammatory compounds that can help combat this underlying issue.

Olive oil contains oleocanthal, which has been shown to work similarly to NSAIDs like ibuprofen at reducing inflammation. The flavonoids in lemons also have significant anti-inflammatory properties, particularly in the digestive tract.

Research published in Current Pharmaceutical Design demonstrated that regular consumption of olive oil significantly reduced inflammatory markers in the blood, potentially lowering the risk of inflammation-related diseases.

Benefit 9: Improves Joint Mobility

For those suffering from joint pain or stiffness, the anti-inflammatory properties of drinking olive oil and lemon juice may provide relief. Olive oil’s oleocanthal not only reduces inflammation but has been specifically studied for its effects on joint health.

A study in the International Journal of Rheumatic Diseases found that olive oil supplementation improved pain scores and decreased morning stiffness in people with rheumatoid arthritis. The vitamin C in lemon juice additionally supports collagen formation needed for cartilage repair.

Regular consumption may help improve mobility and reduce discomfort associated with age-related joint changes or inflammatory conditions.

Benefit 10: Supports Liver Function

Your liver performs over 500 vital functions, including filtering toxins, processing nutrients, and producing bile. The olive oil and lemon juice combination provides specific support for this hardworking organ.

Olive oil helps stimulate bile flow, which aids in digestion and helps remove waste products processed by the liver. Lemon juice contains naringenin, a flavonoid that research has shown can help protect liver cells from damage.

A study in the World Journal of Gastroenterology found that olive oil consumption was associated with lower rates of non-alcoholic fatty liver disease, a growing health concern linked to the modern Western diet.
