Sesame oil has been used for thousands of years in Asian, Middle Eastern, and Mediterranean kitchens, as well as in traditional medicine. Today, it is gaining attention not only as a flavorful cooking oil but also as a functional food rich in bioactive compounds. Its distinctive nutty taste hides a complex profile of unsaturated fats, lignans such as sesamin and sesamolin, and natural vitamin E that may support heart health, blood pressure, blood lipids, and inflammatory balance.

In this guide, you will learn what makes sesame oil different from other vegetable oils, how it is produced, and why its composition matters for your health. We will look at the most studied benefits, from cardiovascular support to metabolic health, and explain realistic expectations rather than marketing promises. You will also find practical advice on how to use sesame oil safely in cooking, how much to take, what to watch out for in terms of side effects, and who should avoid it or speak with a healthcare professional before using it regularly.

Essential insights for using sesame oil

  • Sesame oil provides mostly unsaturated fats plus sesame lignans that may support heart health and oxidative stress balance.
  • Regular use appears to modestly improve blood pressure and blood lipid markers in some people when part of an overall healthy diet.
  • Typical intake for health-focused use is around 10–30 mL (about 2–6 teaspoons) of sesame oil per day from food.
  • People with known sesame allergy or suspected seed allergies should avoid sesame oil, especially unrefined varieties.
  • Individuals on blood-thinning, blood pressure, or diabetes medications should discuss regular sesame oil use with their clinician.

What is sesame oil and how does it work?

Sesame oil is a vegetable oil pressed from the seeds of the sesame plant (Sesamum indicum). Depending on how it is processed, it can be light in flavor and color (from raw or lightly roasted seeds) or deep, aromatic, and dark (from heavily toasted seeds). Refined sesame oil is often pale and neutral, used for higher-heat cooking, while unrefined or cold-pressed oils retain more flavor and bioactive compounds.

Nutritionally, sesame oil is dominated by unsaturated fats. Roughly speaking, it contains a mix of monounsaturated fats (mainly oleic acid) and polyunsaturated fats (mainly linoleic acid), with only a small proportion of saturated fat. This profile is broadly similar to other liquid vegetable oils and is one reason it is often considered “heart-friendly” when it replaces saturated fats such as butter or palm oil in the diet.

What makes sesame oil stand out is its content of unique lignans, particularly sesamin and sesamolin, and related compounds formed during processing (like sesamol). These molecules act as antioxidants and appear to influence enzymes involved in lipid metabolism, blood pressure regulation, and oxidative stress. In addition, sesame oil contains natural tocopherols (vitamin E–like compounds), which further contribute to its antioxidant capacity.

From a physiological perspective, sesame oil may support cardiovascular and metabolic health through several mechanisms:

  • Improving the balance of blood lipids (for example, lowering triglycerides in some studies).
  • Modestly influencing blood pressure when used regularly in place of other fats.
  • Helping to buffer oxidative stress and inflammation by stabilizing cell membranes and lipids.
  • Supporting bile acid and cholesterol metabolism via its lignans and unsaturated fats.

It is important to understand that sesame oil is still an energy-dense fat, providing about 9 kcal per gram. Any health benefit comes from how it fits into the entire pattern of your diet and lifestyle, not from isolated high-dose use on top of an otherwise unhealthy pattern.

Sesame oil health benefits for heart, metabolism, and more

Most modern interest in sesame oil focuses on cardiovascular and metabolic health. Human trials and systematic reviews suggest several potential benefits, although the size of these effects is generally modest and depends on context.

For blood lipids, regular sesame consumption (including oil) can reduce triglycerides and sometimes improve other lipid markers, especially when it replaces less healthy fats or is combined with weight loss and other lifestyle changes. Several controlled trials report better triglyceride levels and small improvements in cholesterol fractions in people with conditions like high blood pressure, dyslipidemia, or non-alcoholic fatty liver disease when sesame oil forms part of the dietary fat pattern.

Blood pressure is another area where sesame oil shows promise. Some intervention studies in hypertensive adults have found that substituting sesame oil for other cooking oils leads to noticeable reductions in systolic and diastolic blood pressure over several weeks. A blend of sesame oil with other oils, such as rice bran oil, has also been studied, suggesting that sesame oil can contribute to improved vascular function and blood pressure control when integrated into a broader heart-healthy regimen.

Sesame oil’s lignans and vitamin E content contribute to antioxidant and anti-inflammatory effects. Clinical and preclinical work indicates reductions in markers of oxidative stress and subtle shifts in inflammatory biomarkers with sesame-based interventions. While these changes may not be dramatic in the short term, they could support long-term vascular and metabolic health when combined with other preventive strategies.

There is also emerging evidence that sesame oil may support aspects of metabolic health, such as fasting blood glucose, insulin sensitivity, and liver fat in individuals with metabolic syndrome or type 2 diabetes. However, results are mixed, and improvements tend to occur when sesame oil intake is part of a structured dietary intervention rather than when added on top of existing calorie intake.

Beyond cardiovascular and metabolic outcomes, sesame oil is used traditionally for joint comfort, oral health (oil pulling), and skin care. Limited research suggests potential benefits for oral hygiene and skin barrier function, but these uses are supported more by tradition and small studies than by large clinical trials. They should be viewed as complementary rather than primary treatments.

Overall, sesame oil can be a helpful part of a cardiometabolic support plan when it replaces less healthy fats and is combined with a plant-rich, fiber-rich diet, physical activity, and medical care where needed.

How to use sesame oil day to day

To benefit from sesame oil, think in terms of replacement rather than addition. You are not aiming to pour sesame oil on top of everything you already eat, but to swap it for less favorable fat sources, such as butter, lard, or ultra-processed oils, in everyday meals.

In the kitchen, there are three main types you will encounter:

  • Light or refined sesame oil: Pale, mild, and better suited for higher-heat cooking such as stir-frying or sautéing. Much of the strong aroma is removed, but it still provides unsaturated fats and some bioactive compounds.
  • Cold-pressed or unrefined sesame oil: Stronger in flavor and aroma, usually golden in color. Best for low to medium heat, salad dressings, finishing drizzles, and dips.
  • Toasted (dark) sesame oil: Very aromatic, deep brown, and usually used as a flavoring rather than a primary cooking fat. A small amount goes a long way.

Practical ways to use sesame oil include:

  • Replacing part of the butter or other oils in stir-fries, curries, and sautéed vegetables with light sesame oil.
  • Making salad dressings by whisking sesame oil with lemon juice or vinegar, herbs, and a small amount of mustard or miso.
  • Adding a teaspoon of toasted sesame oil at the end of cooking soups, stews, or grain bowls for flavor.
  • Mixing sesame oil with other oils (such as olive or canola) to balance flavor and fatty acid profile in daily use.

Topically, sesame oil is used as a massage oil, for scalp treatments, and in some traditional practices like oil pulling. When used on skin:

  • Choose a high-quality, preferably cold-pressed oil.
  • Patch-test a tiny amount on the inner forearm to check for irritation or allergy.
  • Use a thin layer rather than large amounts, especially on acne-prone or sensitive skin.

For oil pulling (swishing oil in the mouth), traditional practices often use 1 tablespoon of oil swished for several minutes and then spat out. Evidence for this practice is limited; if you choose to try it, treat it as a complementary oral hygiene step, not a substitute for brushing, flossing, or dental care.

Store sesame oil in a cool, dark place, tightly closed, to slow oxidation. Unrefined and toasted oils are more prone to flavor changes over time, so buy smaller bottles and use them within a few months of opening.

Sesame oil dosage and how much per day

There is no official “recommended dose” of sesame oil, because it is classified as a food rather than a drug. Most health-focused guidance therefore looks at typical amounts used in diets and in clinical studies rather than a single fixed number for everyone.

For general health and cardiovascular support, a common practical range is:

  • About 10–30 mL per day (roughly 2–6 teaspoons, or ½–2 tablespoons) of sesame oil, usually divided across meals.

This range aligns reasonably well with amounts used in many studies and fits within usual recommendations for total daily fat intake for adults when sesame oil is part of, rather than in addition to, overall dietary fat.

When thinking about dosage, keep in mind:

  • Total calories: One tablespoon (15 mL) of sesame oil provides around 120 kcal. Regularly exceeding your total energy needs by adding oil can lead to weight gain, which may offset cardiovascular benefits.
  • Balance with other fats: Sesame oil is relatively high in omega-6 linoleic acid compared with omega-3 fats. It is wise to pair sesame oil intake with sources of omega-3 (such as flaxseed, chia, walnuts, or fatty fish) and to avoid an overall pattern dominated by omega-6-rich oils.
  • Clinical conditions: In some trials involving people with hypertension, type 2 diabetes, or fatty liver disease, sesame oil replaced other cooking oils as the primary culinary fat, sometimes amounting to 20–30 mL or more daily. These protocols were usually supervised and part of comprehensive lifestyle changes.

Practical dosage approaches include:

  1. Culinary replacement strategy
  • Choose one or two meals per day where you replace your usual cooking fat (butter, ghee, other oils) with light or unrefined sesame oil.
  • Aim for a total of 10–20 mL (about 2–4 teaspoons) across those meals.
  1. Flavorful topping strategy
  • Use 1–2 teaspoons of toasted sesame oil as a finishing drizzle on soups, stir-fries, and grain bowls instead of heavy sauces or spreads.
  1. Mixed oils strategy
  • Blend sesame oil with another oil (for example, olive or canola) in a 1:1 ratio to create a versatile cooking and dressing oil, using 1–2 tablespoons of the blend daily.

Higher intakes may be appropriate in some clinical contexts but should be supervised, especially for people with complex medical conditions or those taking multiple medications. If you are considering using sesame oil more aggressively for blood pressure, lipid control, or glucose management, discuss your plan with a healthcare professional who can monitor your overall diet, medications, and lab markers.

Sesame oil side effects and who should avoid it

For most healthy adults, culinary amounts of sesame oil are well tolerated. However, as with any concentrated food, there are important caveats.

The most serious concern is allergy. Sesame is a well-recognized allergen, and reactions can range from mild skin symptoms to severe anaphylaxis. While highly refined oils may contain fewer allergenic proteins, cold-pressed and unrefined sesame oils can carry enough protein to provoke reactions in sensitive individuals. Anyone with a known sesame allergy, or a history of serious reactions to seeds, should avoid sesame oil altogether unless they have been specifically cleared by an allergist.

Because sesame oil is calorie-dense, overuse can contribute to weight gain if overall calorie intake is not adjusted. This is particularly relevant for people managing obesity, type 2 diabetes, or fatty liver disease. Health benefits seen in research typically occur when sesame oil is integrated into a calorie-appropriate, structured diet, not when it is simply added on top.

There are also potential interactions with medications. Clinical trials have noted improvements in blood pressure, lipid levels, and sometimes blood glucose when sesame oil is used regularly. While these are generally positive changes, they can theoretically interact with:

  • Blood pressure medications (risk of additive hypotensive effect).
  • Diabetes medications or insulin (modest changes in glycemic control).
  • Anticoagulant or antiplatelet drugs (because of changes in lipid and inflammatory status, though direct effects on coagulation are not well established).

People taking these medications should not stop or adjust their prescriptions on their own. Instead, they should inform their clinician if they plan to significantly increase sesame oil intake so that blood pressure, glucose, and other markers can be monitored and medications adjusted if necessary.

Digestive side effects are usually mild and may include loose stools or stomach discomfort when oil intake suddenly increases. Introducing sesame oil gradually and consuming it with meals rather than on an empty stomach can reduce these effects.

Groups that should be especially careful or seek medical guidance before regular high intake include:

  • Individuals with known or suspected sesame allergy.
  • People on multiple cardiovascular or diabetes medications.
  • Those with gallbladder disease or fat malabsorption syndromes.
  • Pregnant or breastfeeding women considering intake well above typical culinary amounts (normal food use is generally considered acceptable, but high-dose supplementation is less studied in these groups).

If you notice new symptoms such as itching, swelling, shortness of breath, marked blood pressure changes, or unusual bruising after increasing sesame oil intake, seek medical help promptly.

Research evidence on sesame oil

The scientific literature on sesame and sesame oil has grown significantly over the last two decades. While older work often focused on basic chemistry and animal models, more recent research includes human clinical trials and meta-analyses. Together, they provide a clearer picture of how sesame oil may influence cardiovascular and metabolic health.

Comprehensive reviews of sesame seed oil describe its composition and highlight its high content of unsaturated fatty acids, lignans, and tocopherols, along with their antioxidant and potential health-promoting actions. These reviews underline that sesame oil’s effects arise from both its fatty acid profile and its unique non-fat components.

Systematic reviews and meta-analyses of clinical trials have evaluated the impact of sesame oil on metabolic biomarkers such as blood lipids, blood pressure, and markers of oxidative stress. Overall, they report:

  • Modest reductions in triglycerides and sometimes small improvements in other lipid fractions when sesame oil or sesame-rich interventions are used regularly.
  • Small but meaningful improvements in blood pressure, especially in individuals with hypertension or metabolic abnormalities, particularly when sesame oil replaces other dietary fats.
  • Favorable changes in oxidative stress markers and some inflammatory biomarkers, suggesting an antioxidant and anti-inflammatory influence, though effect sizes vary between studies.

Additional meta-analyses looking at sesame consumption more broadly (including seeds, oil, and sesame-derived products) support these findings. They indicate consistent triglyceride-lowering effects and small improvements in cardiovascular risk markers, with less consistent changes in total or LDL cholesterol. Importantly, some subgroup analyses suggest that sesame oil interventions may sometimes yield clearer triglyceride benefits than whole or ground seeds, though both can be useful within an overall diet pattern.

Beyond cardiovascular and metabolic endpoints, reviews also explore sesame’s possible roles in liver health, bone metabolism, and neuroprotection, but these areas are less well established and rely more on animal and mechanistic studies than on large human trials.

A few important themes emerge from this body of evidence:

  • Benefits typically arise when sesame oil is integrated into a balanced diet, often alongside weight management and other lifestyle changes.
  • Most trials are relatively small and short-term, so we have better evidence for intermediate markers (lipids, blood pressure) than for hard outcomes like heart attacks or strokes.
  • Safety in culinary amounts appears good, but high-dose, long-term supplementation, especially in vulnerable populations, has not been extensively studied.

Taken together, the research supports sesame oil as a reasonable choice among plant-based oils, particularly when used to replace saturated fats and ultra-processed fats, with potential added advantages from its lignans and antioxidant content.
