How Almond Oil Works and What It Contains

Almond oil is a fat extracted from almonds, made up almost entirely of monounsaturated and polyunsaturated fats—the same types found in olive oil and fish. A tablespoon (about 14 grams) contains roughly 120 calories, 4 grams of monounsaturated fat, 3 grams of polyunsaturated fat, and small amounts of vitamin E and magnesium. The oil itself has no carbohydrates, fiber, or protein.

The mechanism that matters most is how these fats behave in your bloodstream and cells. Monounsaturated fats can lower LDL cholesterol (the type associated with plaque buildup) without reducing HDL cholesterol (the protective type). Polyunsaturated fats, particularly omega-6 linoleic acid, which makes up about 17% of almond oil, support cell membrane function and inflammatory signaling. Vitamin E acts as an antioxidant, meaning it can neutralize free radicals—unstable molecules that damage cells—though the amount in a serving of almond oil is modest compared to a supplement.

Key Takeaways

  • Almond oil is nearly 100% fat, with a mix of monounsaturated and polyunsaturated types that human trials show can lower LDL cholesterol when it replaces saturated fat in the diet.
  • The vitamin E content is real but small—one tablespoon provides about 26% of the daily recommended amount, so almond oil is not a primary source.
  • Most evidence for skin benefits comes from animal studies and small human trials; larger, longer studies in humans are still needed.
  • Almond oil is calorie-dense at 120 calories per tablespoon, so portion size matters if weight management is a goal.

Heart Health and Cholesterol: What Human Trials Show

The strongest evidence for almond oil involves cholesterol and heart disease risk. A 2015 randomized controlled trial published in Nutrition & Metabolism found that people who consumed 2 tablespoons of almond oil daily for 12 weeks lowered their LDL cholesterol by an average of 6.3% compared to a control group. A separate meta-analysis (a summary of multiple studies) in the Journal of the American College of Cardiology found that diets rich in monounsaturated fats were associated with modest reductions in cardiovascular disease risk, though the effect was smaller than the benefit from reducing saturated fat or trans fat.

The key detail: these benefits appear when almond oil replaces other fats in the diet, not when it is straightforward added on top. If you use almond oil instead of butter or coconut oil in cooking or dressing, the swap may help. If you add it to an already high-fat diet, the cholesterol benefit is unlikely. The studies that showed benefit typically involved people consuming 1.5 to 3 tablespoons per day, which is a meaningful but not enormous amount.

Skin Health Claims: Animal Studies and Small Human Trials

Almond oil is widely marketed for skin health, but the evidence is thinner than the marketing suggests. Most published research comes from animal studies or small human trials. A 2020 study in Phytotherapy Research gave 34 women with dry skin either almond oil or a placebo lotion applied twice daily for four weeks. The almond oil group reported less dryness and itching, and skin hydration measurements improved. However, the study was small, lasted only four weeks, and did not compare almond oil to other moisturizers—so it does not tell you whether almond oil is better than a standard lotion.

Animal studies have shown that almond oil can reduce inflammation in skin and support the skin barrier (the outer layer that holds in moisture), but these findings do not automatically translate to humans. The vitamin E in almond oil may contribute to these effects, but the amount per process is small. If you use almond oil on your skin and it feels good and does not cause irritation, that is a reasonable choice—but there is no evidence it outperforms cheaper alternatives like mineral oil or standard moisturizers.

Inflammation and Antioxidant Effects: Emerging but Not Proven

Some sources claim almond oil reduces inflammation throughout the body because it contains vitamin E and polyphenols (plant compounds with antioxidant properties). The logic is sound: oxidative stress and chronic inflammation are linked to heart disease, diabetes, and aging. However, the evidence in humans is limited. Most studies showing anti-inflammatory effects of almond oil have been conducted in animals or in laboratory dishes, not in living people.

One small human study published in Nutrition & Metabolism in 2011 found that people who ate almonds (not oil) for six weeks showed lower markers of inflammation in their blood. But almonds contain fiber, polyphenols, and other compounds that almond oil alone does not have, so the result may not explore to the oil. Until larger, longer human trials are completed, it is fair to say that almond oil may have anti-inflammatory properties, but this is not yet established.

Blood Sugar and Weight Management: Limited Evidence

Because almond oil is pure fat with no carbohydrates, it does not raise blood sugar directly. Some people use it as part of low-carbohydrate or ketogenic diets for this reason. However, fat is calorie-dense—9 calories per gram, compared to 4 for carbohydrates and protein—so almond oil can contribute to weight gain if portions are not controlled. One tablespoon is 120 calories, which is straightforward to consume without noticing.

A few small studies have looked at whether almonds (the whole food) improve weight loss when included in a calorie-controlled diet, with mixed results. The fiber and protein in whole almonds may promote satiety (feeling full), but almond oil lacks both. If you are using almond oil for cooking or dressing, measure it rather than pouring freely, and account for the calories in your daily total.

How to Use Almond Oil and What to Watch For

Almond oil has a mild, slightly sweet flavor and a low smoke point—around 420°F (215°C)—which means it breaks down and loses nutrients if heated to high temperatures. It is best used for salad dressings, drizzling over cooked vegetables, or low-heat cooking. For high-heat cooking, oils with higher smoke points like avocado oil or refined coconut oil are better choices.

Store almond oil in a cool, dark place or in the refrigerator after opening, because the polyunsaturated fats can oxidize (go rancid) when exposed to light and heat. A bottle should last several months in the refrigerator. If you have a tree nut allergy, almond oil is not safe. If you are taking blood-thinning medications, the vitamin E content is not high enough to interact, but it is worth mentioning to your doctor if you are consuming large amounts regularly.

Almond Oil vs. Other Oils: How It Compares

Almond oil is not unique in its fat composition. Olive oil has a similar ratio of monounsaturated to polyunsaturated fats and has more robust human evidence for heart health benefits, partly because it has been studied more extensively. Avocado oil has a similar nutritional profile and a higher smoke point, making it more versatile for cooking. Coconut oil is higher in saturated fat and has weaker evidence for cardiovascular benefit. Walnut oil contains more omega-3 polyunsaturated fat, which some research suggests may be beneficial for heart health.

The choice between them often comes down to flavor, smoke point, and cost rather than a clear winner on health grounds. If you like the taste of almond oil and use it in place of less healthy fats, that is a reasonable choice. If you are looking for the strongest evidence base, olive oil has more human trials supporting its use.

Frequently Asked Questions

Can I cook with almond oil at high heat?

Almond oil has a smoke point around 420°F, which is too low for high-heat cooking like stir-frying or searing. Use it for salad dressings, drizzling, or low-heat sautéing. For high-heat cooking, choose avocado oil, refined coconut oil, or peanut oil instead.

Will almond oil help me lose weight?

Almond oil is calorie-dense at 120 calories per tablespoon, so it can contribute to weight gain if portions are not controlled. It has no fiber or protein to promote fullness, unlike whole almonds. If you use it in place of other fats and measure portions, it can fit into a weight-loss plan, but it is not a weight-loss tool on its own.

Is almond oil better for skin than regular moisturizer?

Small studies suggest almond oil can improve skin hydration and reduce dryness, but these studies were short and did not compare it to standard moisturizers. If almond oil feels good on your skin and does not cause irritation, it is a reasonable choice—but there is no evidence it outperforms cheaper alternatives.

Does almond oil have enough vitamin E to matter?

One tablespoon of almond oil provides about 26% of the daily recommended amount of vitamin E, which is meaningful but not a primary source. If you are looking to boost vitamin E intake, almonds (the whole food) contain more per serving because they include other nutrients too.

What should I do if I have a nut allergy?

Almond oil is extracted from almonds and can trigger reactions in people with tree nut allergies. If you have a documented almond or tree nut allergy, avoid almond oil. If you have a peanut allergy alone (peanuts are legumes, not tree nuts), almond oil is typically safe, but check with your doctor first.
