Argan Oil

Heart health and cholesterol This is the most researched area for culinary argan oil, and the evidence is reasonably compelling — though still limited to small, short-term studies. In multiple human trials, participants who replaced butter or other saturated-fat sources with 15–30 mL of argan oil per day for 3–4 weeks saw reductions in total cholesterol, LDL cholesterol, and triglycerides (blood fats linked to cardiovascular risk). Some trials also reported increases in HDL ("good") cholesterol. One well-cited study in people with dyslipidaemia (abnormal blood fat levels) found that 25 mL per day for three weeks not only improved the lipid profile but also reduced platelet aggregation — the tendency of platelets (small blood cells) to clump together, which contributes to clot formation — and lowered thromboxane B2, a marker related to clotting and arterial inflammation. These are surrogate markers (measurable signs associated with risk) rather than hard outcomes like heart attack or stroke. No large long-term trial has yet confirmed that argan oil directly prevents cardiovascular events, and no major cardiology society has issued specific argan oil guidelines. Its heart-supporting profile is consistent with broader evidence favouring unsaturated plant oils over saturated fats. Antioxidant status and vitamin E Multiple clinical trials have shown that regular consumption of culinary argan oil measurably raises serum vitamin E levels — particularly gamma-tocopherol — in healthy adults and in postmenopausal women. Gamma-tocopherol is especially effective at neutralising reactive nitrogen species, a type of free radical that alpha-tocopherol (the form in most supplements) is less efficient at neutralising. Studies also report reduced TBARS (thiobarbituric acid reactive substances — a standard lab marker of lipid peroxidation, meaning fat damage caused by oxidation). In practical terms, this suggests that regular culinary use may help reduce overall oxidative load, which is a background driver of cellular ageing and chronic disease. Inflammation and joint health Evidence here is promising but early. A randomised controlled trial — the gold standard in research — found that people with knee osteoarthritis (joint wear-and-tear disease) who consumed 30 mL of argan oil daily for eight weeks reported meaningful improvements in pain and functional scores compared to a control group. However, direct inflammatory biomarkers such as CRP (C-reactive protein, a standard blood marker of inflammation) or cytokines (signalling proteins involved in the inflammatory response) were not the primary outcome. Most mechanistic support comes from animal studies and from the known anti-inflammatory roles of tocopherols, phytosterols, and polyphenols. More robust human data is needed before argan oil can be recommended specifically for inflammatory conditions. Blood sugar and metabolism Evidence in this area is emerging and limited. Some clinical work using around 7–8 mL per day reported improvements in surrogate metabolic markers, and the oil's high unsaturated fat content aligns with general dietary patterns associated with better insulin sensitivity. However, no large controlled human trial has specifically targeted fasting glucose, insulin, or HbA1c (a measure of average blood sugar over three months) as primary outcomes. Argan oil's role here is best described as part of an overall strategy of replacing saturated fats with unsaturated ones — not as a targeted glycaemic therapy. Digestive health No well-controlled human trials have specifically evaluated argan oil for gut health or microbiome changes. As a fat, it supports the absorption of fat-soluble nutrients like vitamin E and carotenoids from the rest of your meal, which may indirectly support mucosal (gut lining) health. At high intakes above typical culinary use, some individuals report mild nausea or loose stools — a response common to many oils rather than unique to argan oil. Skin health from within Most documented skin benefits of argan oil — improved hydration, elasticity, and barrier function — come from topical (directly applied) cosmetic-grade oil. There is limited but plausible evidence that oral consumption could support skin health indirectly via improved vitamin E status, which protects skin-cell membranes from oxidative damage. This remains a secondary and less-studied benefit compared to topical use.

This distinction matters and is worth being clear about. Only food-grade (culinary) argan oil should be eaten. Here is why the two differ: | Feature | Culinary (roasted) argan oil | Cosmetic (unroasted) argan oil | | --- | --- | --- | | Kernel preparation | Lightly roasted | Unroasted | | Flavour | Warm, nutty, toasty | Neutral to bland | | Food safety standards | Produced for human consumption | Not always food-grade | | Intended use | Cooking, finishing dishes | Skin, hair, nails | | Suitable to eat? | Yes | Not unless explicitly labelled for food use | Cosmetic argan oil is not produced under food-safety controls and may be oxidised, solvent-treated, or blended — none of which are concerns you want to introduce into your diet. A common question is: "Can I eat the argan oil I use on my hair?" The short answer is no, not unless the label explicitly states it is food grade.

Human trials have used between 15 mL (about 1 tablespoon) and 30 mL (about 2 tablespoons) per day for periods of 3–8 weeks, with no serious adverse events reported at these doses. Traditional Moroccan culinary use tends toward 1–2 teaspoons per meal as a finishing drizzle, which aligns with the lower end of the studied range. A sensible starting framework: Start with 1 teaspoon (about 5 mL) per day as a finishing drizzle to assess tolerance, particularly if you are not accustomed to higher-fat foods. A daily target of 1 tablespoon (about 15 mL) represents a practical, evidence-aligned amount for most healthy adults, consistent with the dose used in several clinical trials. Up to 2 tablespoons (30 mL) per day was used in trials without safety concerns, but this is a significant calorie contribution (around 240 calories) and should comfortably replace, not supplement, other added fats in the diet. Supplement capsules exist but are less well-studied than culinary oil and offer no practical advantage for most people who can easily incorporate the oil into food. There is no established official recommended intake for argan oil specifically. The general guidance from nutrition bodies to replace saturated fats with unsaturated plant oils is the framework into which argan oil fits most naturally.

The everyday Mediterranean or Moroccan-style cook Already relies on plant oils, pulses, and whole grains as dietary staples Wants a flavourful finishing oil that brings culinary interest and a vitamin E boost Can easily substitute argan oil for butter in dishes like couscous or grain bowls without changing cooking habits significantly Gains additional antioxidant diversity compared to using olive oil alone Adults with mildly elevated LDL cholesterol or triglycerides seeking dietary support Has been advised to reduce saturated fat intake and is actively replacing butter or margarine Is looking for a practical, food-first strategy rather than or alongside supplementation Can use 1–2 tablespoons per day as a direct butter substitute in sauces, spreads (amlou), and finishing drizzles Should continue to monitor cholesterol levels with their healthcare provider and understand that argan oil alone is not a treatment

Argan oil is rich in oleic acid (43–49%) and linoleic acid (29–36%), which are monounsaturated and polyunsaturated fats that support heart health. It also contains high levels of gamma-tocopherol (vitamin E), rare phytosterols like schottenol, and antioxidant polyphenols.

Culinary argan oil is best used as a finishing oil rather than a frying fat to preserve its delicate flavor and nutritional compounds. You can drizzle it over cooked couscous, tagines, or roasted vegetables, and it is a key ingredient in the traditional Moroccan almond spread called amlou.

Argan oil contains unique plant sterols called schottenol and spinasterol that compete with dietary cholesterol for absorption in the intestine. Studies suggest that consuming 1–2 tablespoons daily may improve cholesterol profiles and lower LDL ("bad") cholesterol.

Individuals with tree nut, seed, or sesame allergies should be cautious, as argan oil is derived from a tree nut family. It may also interact with blood-thinning medications like warfarin or aspirin due to its vitamin E content and effects on blood platelets.

Argan oil is an excellent source of gamma-tocopherol, providing roughly 600–900 mg per kilogram of oil. This specific form of vitamin E acts as a potent antioxidant that neutralizes free radicals in cell membranes and helps protect blood lipids from oxidation.

Amlou is a traditional Moroccan breakfast spread made by blending toasted ground almonds, raw honey, and culinary argan oil into a thick paste. It is typically served with flatbread and provides a concentrated dose of unsaturated fats, polyphenols, and vitamin E.

Culinary argan oil is widely available at specialty grocers like Whole Foods Market and through major online retailers like Amazon. While less common in standard supermarkets, you can often find high-quality, USDA Organic certified versions in the international or health food aisles.

When buying argan oil in the US, look for the USDA Organic seal and ensure the label specifies the oil is 'culinary' or 'food grade.' Because argan oil is an imported specialty product, the USDA Organic certification helps ensure the oil was produced without synthetic pesticides or GMOs.

Argan oil is not produced in the United States; it is exclusively imported from the Arganeraie Biosphere Reserve in southwestern Morocco. The argan tree (Argania spinosa) is endemic to this specific North African region, meaning all authentic culinary argan oil found in US stores is an import.

In the US, culinary argan oil is most commonly used as a gourmet finishing oil in Mediterranean-style diets or as a plant-based alternative to butter. Its popularity has grown within the American 'food as medicine' movement, where it is prized for its high vitamin E content and heart-healthy monounsaturated fats.
