You've probably seen the TikToks or heard your health-nut aunt raving about it. Swigging a spoonful of "liquid gold" right before hitting the hay. It sounds a bit greasy, honestly. But people swear by it for everything from glowing skin to a smoother digestive system. If you're standing in your kitchen at 11 PM wondering how much olive oil should i drink before bed, you aren't alone. It’s a trend with some actual science behind it, but it’s easy to overdo.
Don't just grab the bottle and chug.

The short answer for most people is roughly one tablespoon. That's about 15ml. It’s enough to trigger the biological benefits without making you feel like you just ate a deep-fried shoe. Some hardcore enthusiasts push it to two tablespoons, but that's a lot of fat to dump into your system right before your body tries to shut down for repair.
Why are people actually doing this?
It isn't just a weird internet dare. Extra Virgin Olive Oil (EVOO) is packed with polyphenols and monounsaturated fatty acids. Specifically, oleic acid. When you take it at night, your body is entering a fasting state where it focuses on cellular repair.
Think about your gallbladder. It spends the day storing bile. When you ingest a concentrated dose of healthy fat like olive oil, it triggers the gallbladder to contract and release that bile. This can help prevent gallstones and keeps the digestive "plumbing" moving. If you struggle with constipation, this nighttime ritual is often more effective than a morning dose because it has eight hours to work its magic while you sleep.
It’s also about inflammation. Real EVOO contains a compound called oleocanthal. It actually mimics the effect of ibuprofen. It inhibits the COX-1 and COX-2 enzymes. Taking it before bed means you're providing your body with an anti-inflammatory hit right when natural cortisol levels—the body's built-in anti-inflammatory—are at their lowest point in the 24-hour cycle.
The calorie trap nobody mentions
Here is the thing. Olive oil is dense.
One tablespoon is about 120 calories.
If you’re doing two, that’s 240 calories.
If you just add this to your current diet without changing anything else, you’re looking at gaining about two pounds a month. Purely from the oil. You've got to be smart. If you're going to drink it at night, maybe skip the butter on your toast at lunch or the mayo on your sandwich. It’s a trade-off, not just an "add-on" if weight management is a goal for you.
Finding the right dose: How much olive oil should i drink before bed for my body?
Not everyone is built the same. A 200-pound athlete has different metabolic needs than someone half their size.

- For the beginners: Start with a teaspoon. Seriously. Jumping straight to a tablespoon can cause "disaster pants." Your gallbladder might overreact to the sudden fat load, leading to cramping or urgency. Give it three nights. If your stomach feels fine, move up.
- For digestive health: One tablespoon is the sweet spot. Research often points to this amount for lubricating the intestines.
- For heart health: The famous PREDIMED study, which looked at the Mediterranean diet, generally suggests about 4 tablespoons a day total. If you’ve already had plenty of oil in your salads during the day, you might not need any at bedtime.
The quality matters more than the quantity
If you’re drinking the cheap, clear plastic bottle stuff from the bottom shelf, stop. You’re basically just drinking empty fat. To get the medicinal benefits, it has to be Extra Virgin. It needs to be in a dark glass bottle or a tin. Light destroys the polyphenols.
Actually, there’s a "cough test." High-quality, fresh olive oil contains so much oleocanthal that it should sting the back of your throat. It might even make you cough. Experts like Dr. Mary Flynn from Brown University have noted that this pungent sensation is a direct indicator of the oil's health potency. If it tastes like bland vegetable oil, it’s probably old or fake. And yeah, a huge percentage of olive oil on grocery shelves is actually adulterated with cheaper oils.
Look for a harvest date on the label. Not just an expiration date. You want oil from the most recent harvest season.
Potential side effects you shouldn't ignore
It isn't all sunshine and rainbows.
Drinking oil before bed can trigger acid reflux (GERD) in some people. Fat relaxes the lower esophageal sphincter. That’s the little trapdoor that keeps stomach acid down. If that door stays open because you just downed a shot of oil and then laid flat, you might wake up with a burning throat.
If you have a history of pancreatitis or active gallbladder issues, talk to a doctor first. Pushing the gallbladder to work that hard can be painful if you already have undiagnosed stones.
A better way to swallow it?
If the idea of drinking it straight makes you gag, you're not a failure. It's a weird texture.
Try mixing it with a tiny squeeze of lemon juice. The acidity cuts the greasiness and the vitamin C actually helps with the absorption of certain nutrients. Plus, it tastes a bit like a salad dressing rather than a car lubricant.
Some people also find that a tiny pinch of sea salt helps.
What the science says about the "Bedtime" timing
Is it actually better at night?
There isn't a massive clinical trial specifically comparing "morning oil" vs "night oil." Most Mediterranean studies focus on total daily intake. However, the anecdotal evidence regarding sleep quality is interesting. Some suggest that the healthy fats help stabilize blood sugar throughout the night. If you’re the type of person who wakes up at 3 AM with a racing heart, it might be a blood sugar crash. A shot of oil provides a slow-burning fuel source that might keep you in a deeper sleep.
But again, don't expect miracles if the rest of your diet is a mess.
Actionable Steps for Tonight
If you want to try this out, follow this specific protocol to avoid a midnight stomach ache:

- Select your oil: Check your pantry. Is it Extra Virgin? Is it in a dark bottle? If yes, proceed. If it's "Light Olive Oil" (which just means refined), it won't do much for you.
- The 15-minute rule: Don't drink the oil and immediately dive into bed. Drink it about 15 to 30 minutes before you plan to lie down. This gives your stomach a head start on processing it while you're still upright, reducing the risk of reflux.
- The starter dose: Pour exactly one teaspoon for the first two nights. It's better to be underwhelmed than to spend the night in the bathroom.
- Monitor your morning: Pay attention to how you feel when you wake up. Are you less bloated? Is your skin less dry after a week? Did you have a "productive" morning bathroom visit?
- Adjust the daily balance: If you decide to make the one tablespoon (15ml) dose a permanent habit, reduce your fat intake elsewhere by about 120 calories to maintain your current weight.
Drinking olive oil is a tool, not a magic potion. Used correctly, it’s a powerful way to support your heart and gut. Just keep the bottle in a cool, dark cupboard—never on the counter next to the stove where heat can turn those healthy fats rancid.
