Is Drinking Extra Virgin Olive Oil Safe-or Risky?
Yes, drinking extra virgin olive oil is generally safe for most healthy adults in small to moderate amounts, but it is not a magic health shot and it can cause nausea, stomach upset, or too much calorie intake if you drink a lot at once. Public health and medical references describe olive oil as usually well tolerated by mouth, with extra virgin olive oil commonly consumed in foods and used safely in Mediterranean-style diets; one reference notes use of up to 1 liter weekly in that context, though that does not mean chugging it is advisable.
What "safe" means here
When people ask whether extra virgin olive oil is safe to drink, the practical answer depends on dose, timing, and your health conditions. Olive oil is food, so swallowing a spoonful or using it in meals is normal; drinking it in large amounts as a daily habit is a different question because concentrated fat can trigger gastrointestinal symptoms and add a lot of calories quickly.
Extra virgin olive oil is the least processed form, mechanically pressed without high heat or chemical solvents, which helps preserve phenolic compounds and antioxidant activity. Harvard Health notes that those compounds may provide added benefits, but also emphasizes that definitive evidence proving extra virgin olive oil is superior to refined olive oil for disease prevention is still limited.
Potential benefits
The strongest evidence for olive oil comes from overall dietary patterns, especially the Mediterranean diet, where olive oil replaces saturated fats rather than being consumed in isolation. Harvard Health says observational studies have linked higher olive oil intake with lower risks of cardiovascular disease, some cancers, and even dementia, while Cleveland Clinic similarly describes extra virgin olive oil as rich in healthy fats and antioxidants.
Olive oil is also mostly monounsaturated fat, which can help lower LDL cholesterol when it replaces saturated fat in the diet. That is one reason nutrition experts often encourage using olive oil as part of meals rather than treating it like a supplement or wellness shot.
Possible risks
The most common downside is digestive discomfort. WebMD notes that olive oil is usually well tolerated when taken by mouth, but it can cause nausea in a small number of people, especially if consumed in larger amounts.
Another issue is calories. A tablespoon of oil is energy-dense, so regularly drinking oil on top of normal meals can make weight management harder even if the oil itself is a healthier fat source than butter or lard. This matters because "healthy" does not mean "limitless," and concentrated fats are easy to overconsume.
There is also a medication interaction to consider. WebMD warns that olive oil might lower blood pressure, so combining it with blood-pressure-lowering medicines could push pressure too low in some people.
Who should be cautious
- People with reflux, gallbladder problems, or frequent nausea, because drinking oil can worsen symptoms.
- People taking blood-pressure medicines, because olive oil may have a mild lowering effect on blood pressure.
- Anyone trying to lose weight, because liquid calories are easy to underestimate.
- Pregnant or breastfeeding people, who should stay with normal food amounts rather than using olive oil as a medicinal drink due to limited safety data for that use.
How much is reasonable
For most adults, a small amount with food is the safest and most practical approach. A spoonful over salad, vegetables, or bread is very different from drinking several ounces straight, and the evidence base supporting benefits generally comes from dietary use rather than bottle-drinking rituals.
- Use it as a food ingredient first, not a supplement.
- Start with a small amount, such as 1 teaspoon to 1 tablespoon.
- Take it with meals to reduce nausea.
- Stop if it causes loose stools, cramping, or reflux.
- Talk to a clinician if you take blood-pressure medicine or have gallbladder disease.
Safety snapshot
| Question | Practical answer | Why it matters |
|---|---|---|
| Can you drink extra virgin olive oil? | Yes, in small amounts | It is commonly consumed as food and usually well tolerated |
| Is it healthy? | Potentially, when it replaces saturated fat | Benefits are tied to the overall diet pattern |
| Can it cause side effects? | Yes, especially nausea or stomach upset | Concentrated fat can be hard to tolerate |
| Can it interact with medicine? | Possibly | It may further lower blood pressure |
What the evidence says
Research has long favored olive oil as part of a healthy diet, but it is important not to overstate what the science proves. Harvard Health notes that while studies show associations with lower cardiovascular risk and other health outcomes, there are no definitive trials showing extra virgin olive oil alone prevents heart disease, cancer, or dementia better than other oils.
In plain language, the best-supported claim is not "drink olive oil for miracles," but "use olive oil, especially extra virgin, as a smart replacement for less healthy fats in a balanced diet." That distinction is crucial for anyone trying to separate real nutrition guidance from social-media health trends.

When to stop and get help
Stop drinking it if you develop persistent nausea, vomiting, abdominal pain, diarrhea, or worsening reflux after taking it. Those symptoms are more likely when oil is consumed quickly or in larger quantities, and they are a sign that your body may not tolerate that method of intake well.
If you have fainting, dizziness, or unusually low blood pressure symptoms after adding olive oil regularly, especially alongside blood-pressure medicine, you should speak with a clinician promptly.
Bottom line for readers
For most adults, extra virgin olive oil is safe to consume in food-sized amounts and may support heart health when it replaces less healthy fats. Drinking it in large quantities is more likely to cause nausea, add excess calories, and create problems for people on certain medications or with digestive issues.
Expert answers to Is Drinking Extra Virgin Olive Oil Safe Or Risky queries
Is drinking a shot of olive oil every morning healthy?
It can be safe for many people in small amounts, but it is not necessary for health, and the evidence for special benefits comes mostly from using olive oil in meals rather than taking it as a daily shot.
Can extra virgin olive oil upset your stomach?
Yes. Olive oil is usually well tolerated, but nausea and stomach upset can happen, especially if you drink too much at once.
Does drinking olive oil help weight loss?
Not by itself. Because olive oil is calorie-dense, drinking it can work against weight loss unless it replaces other calories in the diet.
Is extra virgin olive oil better than regular olive oil?
Extra virgin olive oil has more preserved phenolic compounds because it is less processed, but the strongest proof of added long-term health benefits is still not definitive.
