Drinking Olive Oil Before Bed: Benefits, Sleep, and Digestion

While the Mediterranean diet is widely recognized for its extra virgin olive oil benefits in reducing chronic disease risk, a growing trend involves consuming a small amount of olive oil right before bed. This practice is believed to maximize the oil’s restorative properties, supporting everything from sleep quality to morning digestion.

Key Takeaways

• Sleep Connection: Olive oil contains trace amounts of melatonin, which may help regulate the sleep-wake cycle, contributing to the link between the Mediterranean diet and improved sleep quality.
• Digestive Aid: Due to the fat content, drinking olive oil before bed can support bile flow, act as a mild laxative, and promote healthy gut microbiota, making it excellent for  for digestion.
• Heart Health: As a rich source of monounsaturated fatty acids and polyphenols, regular consumption supports cholesterol management and reduces inflammation, boosting olive oil for heart health.
• Quality Matters: To reap the maximum benefits, always choose extra virgin olive oil (EVOO) due to its higher content of bioactive compounds and antioxidants.

The Nutritional Profile of Olive Oil

The extensive health benefits of olive oil are intrinsically linked to its unique nutritional structure, primarily consisting of fats and powerful bioactive compounds.

Monounsaturated Fatty Acids

Olive oil is predominantly composed of monounsaturated fatty acids (MUFAs), mainly oleic acid, which can make up as much as 83% of the fat content. MUFAs are generally considered “healthy fats” and are less prone to oxygen-induced damage than polyunsaturated fats, contributing to the oil’s stability and protective properties in the body.

Potent Polyphenols

The compounds responsible for the sharp, peppery finish of high-quality extra virgin olive oil come from polyphenols. These compounds, including oleuropein, hydroxytyrosol, and oleocanthal, function have been linked to their antioxidants and anti-inflammatory properties

Their presence are believed to underlie the oil’s health benefits Choosing EVOO, which is minimally processed, ensures the highest concentration of these beneficial phenols.

Can Olive Oil Help You Sleep?

The belief that olive oil can improve sleep quality is linked to two main factors: its unique chemical composition and its systemic effects on metabolism and hunger. This is a key reason why many individuals adopt the practice of drinking olive oil at night, especially when considering olive oil and sleep.

The Melatonin Connection

Recent scientific reviews have investigated the presence of melatonin, a hormone critical for regulating the sleep-wake cycle, in dietary components of the Mediterranean diet. A systematic review from 2023 noted that the consumption of foods typical of the Mediterranean diet, including olive,may increase intake of melatonin and related metabolites.

While the amount of melatonin in a single dose of olive oil may be small, this finding provides a chemical link that supports the observation that greater adherence to the Mediterranean diet is associated with better overall sleep quality.

Stabilizing Blood Sugar

Waking up in the middle of the night can sometimes be triggered by fluctuations in blood sugar. Olive oil’s polyphenols have been associated with better insulin sensitivity and improved glucose metabolism.

Consuming a source of healthy fat like olive oil with meals can help stabilize glucose levels throughout the night, potentially improving sleep onset latency and total sleep time by preventing hunger or metabolic dips that cause arousal.

Digestive and Anti-Inflammatory Benefits

One of the most immediate and noticeable extra virgin olive oil benefits is its positive effect on the gastrointestinal system, making it a popular choice for olive oil for digestion.

Supporting Gut Health

Olive oil and its bioactive compounds contribute to gut health in several key ways, as noted by recent research on gut health and olive oil:

• Prebiotic Effects: Extra Virgin Olive Oil’s phenolic compounds support the growth of beneficial gut microbes while reducing harmful bacteria. This nurturing effect on the microbiome may help the intestinal barrier.
• Enhancing Bile Flow: The consumption of dietary fats, such as olive oil, triggers cholecystokinin (CKK) and stimulates gallbladder contraction to release bile. This process aids in fat digestion and absorbing fat-soluble vitamins, thereby aiding overall digestive function.
• Constipation Relief: Olive oil acts as a gentle lubricant for the digestive tract, which can help soften stools and promote regularity. Some studies suggest a potential benefit in constipation relief.

Reducing Inflammation

Chronic inflammation is a root cause of many health issues. The high concentration of phenolic compounds in EVOO provides significant anti-inflammatory benefits.

Some research shows the compounds in healthy fats, such as olive oil, are foundational to an anti-inflammatory diet. The polyphenol oleocanthal, specifically, has demonstrated anti-inflammatory effects in lab studies that are similar to those of ibuprofen by inhibiting specific enzyme pathways in the body. By reducing systemic inflammation overnight, olive oil may help support cellular repair and reduce oxidative stress.

Heart Health and Cholesterol Management

The most widely supported reason for consuming olive oil daily is its profound impact on cardiovascular health. Regular, light consumption of EVOO is crucial for realizing its full olive oil for heart health potential.

Improving Lipid Profiles

Extra virgin olive oil benefits the heart primarily by enhancing how fats are processed in the body, which directly impacts cholesterol levels.

• Boosting HDL: Polyphenols in EVOO help protect High-Density Lipoprotein (HDL)—often called “good cholesterol”—and enhance the process of cholesterol efflux, which efficiently removes excess cholesterol from tissue and artery walls.
• Lowering LDL:  Regular consumption of EVOO improves lipid profiles and reduces Low-Density Lipoprotein (LDL) concentrations.

Mayo Clinic experts note that replacing saturated and trans fats with healthy MUFAs, like those found in olive oil, can help lower the risk of heart disease and stroke.

Metabolism and Weight Management

Many people who incorporate olive oil into their evening routine do so for its potential role in weight management, specifically controlling nighttime hunger. This suggests a direct link between olive oil and weight loss.

Promoting Satiety

The monounsaturated fatty acids in olive oil play a role in regulating appetite. Research suggests that the consumption of healthy fats, including monounsaturated fats, can slow gastric emptying which can increase feelings of fullness (satiety) and might reduce overall food intake.

Dietary fats like olive oil stimulate the release of key gut hormones, such as cholecystokinin (CCK) which signals to the brain that the body is satisfied. This mechanism is critical for controlling cravings and avoiding unnecessary snacking, which is a key advantage of consuming olive oil at night.

Impact on Abdominal Fat and Nuance

Observational studies have explored the link between olive oil consumption and body composition. Recent findings suggest that regular intake of EVOO may be associated with lower measures of abdominal obesity (belly fat) and healthier weight management over time.

However, researchers note that balance is key. While MUFAs are beneficial, consuming excessive amounts of fat—even healthy fats like olive oil—without corresponding changes in total caloric intake can still contribute to weight gain. Some preliminary studies caution that excessive oleic acid content in the diet may influence fuel fat cell growth. Moderation and substitution of less healthy fats remain the most effective strategies for long-term olive oil and weight loss.

Extra Virgin vs. Regular: Does It Matter?

When integrating olive oil into a wellness routine, the type of oil you choose significantly impacts the level of extra virgin olive oil benefits you receive.

Extra Virgin Olive Oil (EVOO):

• Processing: Made by mechanically pressing olives without the use of high heat or chemical solvents.
• Nutrient Retention: This minimal processing preserves the highest levels of beneficial polyphenols and other antioxidants.
• Benefits: This oil has the highest polyphenol content, is associated with the highest quality oil, offering the richest flavor, deepest color, and has the strongest evidence for health benefits. .

Regular or Refined Olive Oil:

• Processing: Subjected to heat, chemical solvents, or filtration methods.
• Nutrient Loss: This heavy processing strips away most of the healthy phenols and antioxidants.
• Benefits: Contains far loss polyphenols as EVOO which reduces its antioxidant and ant-inflammatory properties..

For all medicinal and wellness purposes, including the nightly routine, Extra Virgin Olive Oil is the recommended choice.

How to Take Olive Oil Before Bed

There is no formal, universally agreed-upon recommended dosage of olive oil for nighttime consumption. However, based on the amounts used in successful clinical and observational trials focusing on general health and appetite regulation, a specific range has emerged.

Recommended Dosage

For those wondering how much olive oil to drink, research studies have used varying amounts, but a consensus suggests starting small:

• General Health: Half a tablespoon (about 7 grams) is often cited as a reasonable starting point.
• For Targeted Benefits (Heart/Digestion): one to two tablespoons (14 to 28 grams) per day has been common in observational Mediterranean diet studies demonstrating cardiovascular benefits.

It is important to start with a low dosage to assess individual tolerance, as larger amounts can cause digestive discomfort.

Consumption Methods

The best way to consume olive oil is the way you enjoy it most and are likely to stick with.

• Straight Shot: Sip it directly if you enjoy the robust, peppery flavor and high phenolic notes.
• Lemon Mix: Stir the oil with a squeeze of fresh lemon juice. This combination may \ improve palatability.
• Drizzled Over Food: Add it to a small serving of plain Greek yogurt or a cup of warm herbal tea (like chamomile) to mellow the taste and add a creamy texture.
• Topical Use: For external benefits, olive oil can be applied directly to the skin as a simple, moisturizing cleanser before bedtime.

Risks and Potential Side Effects

While olive oil is considered safe and a cornerstone of a healthy diet, awareness of potential downsides is important before adopting a nightly routine.

Digestive Concerns

The most common side effect is digestive discomfort, especially when taking a large dose on an empty stomach. Consuming more than a tablespoon may lead to:

• Nausea or Upset Stomach: The high-fat content can be difficult for some to process quickly.
• Diarrhea or Loose Stools: Some people experience loose stools with olive oil which may be amplified in larger quantities.

Medication Interactions

Individuals taking specific medications should consult their doctor before starting a regimen of daily olive oil consumption:

• Blood Pressure: Some studies suggest EVOO may help lower blood pressure, however there is no evidence that normal dietary amounts will interact with antihypertensive medications. As always, it is important to consult with your prescribing physician when taking blood pressure medications.
• Blood Sugar: Olive oil rich diets support glucose regulation. There are no known interactions with insulin or other diabetes medications. Consulting with your physician is always wise when making dietary adjustments while managing glucose disorders.

Calorie Density

Although EVOO supports olive oil and weight loss when substituting less healthy fats, olive oil is calorie-dense. Each tablespoon contains about 120 calories. Adding several tablespoons daily to an already high-calorie diet without reducing other fat sources may contribute to unwanted weight gain.

The Bottom Line

While research on the specific timing of consumption is still evolving, the potential benefits of drinking extra virgin olive oil before bed—including improved digestion, appetite control, and metabolic support—make it a worthwhile habit for many. Olive oil consumption may benefit sleep when viewed in the context of a healthy, Mediterranean-style diet.

Ultimately, whether taken alone or with food, a small daily dose of quality olive oil offers valuable nutrients and antioxidant support that contribute to long-term wellness. While timing is less important, an evening routine may offer gentle, cumulative health benefits.

Frequently Asked Questions

Is it better to drink olive oil in the morning or at night?

There is minimal specific research comparing the timing of olive oil consumption (morning vs. evening). The timing often depends on the desired benefit: night for potential olive oil and sleep support and digestion, or morning for satiety and metabolic boost throughout the day. Consistency and daily intake are more important than timing.

What quality of olive oil should I drink for health benefits?

You should always choose extra virgin olive oil (EVOO). EVOO is mechanically extracted, preserving the high concentration of polyphenols and antioxidants necessary to deliver the potent anti-inflammatory and cardiovascular benefits.

Can olive oil replace my laxative?

Some people report easier bowel movements with high olive oil consumption. However, it should not replace prescribed medications for chronic or severe gastrointestinal conditions without first consulting a healthcare professional.

Is olive oil better than fish oil for heart health?

Both olive oil and fish oil are highly beneficial for heart health, but they work differently. Olive oil provides monounsaturated fatty acids and polyphenols that reduce inflammation and improve cholesterol profiles. Fish oil provides omega-3 polyunsaturated fatty acids (EPA and DHA) that are critical for lowering triglycerides and reducing heart rhythm issues. They are often complementary and can be consumed together.
