Does argan oil lower cholesterol?
Yes, according to a meta-analysis of 5 randomized controlled trials involving 292 participants. Argan oil consumption significantly reduced total cholesterol, LDL cholesterol, and triglycerides while increasing HDL cholesterol. [Evidence: A][1]
Is argan oil good for skin?
Research supports argan oil's skin benefits. A 60-day randomized trial in postmenopausal women found that dietary argan oil consumption significantly improved skin elasticity parameters (R2, R5, R7) compared to olive oil, with p-values below 0.002. [Evidence: B][4]
What are the side effects of argan oil?
Argan oil appears to have a favorable safety profile. A toxicity assessment found an LD50 greater than 5000 mg/kg body weight, indicating very low acute toxicity. No significant adverse effects on body weight, organ weight, or biochemical markers were observed after 28 days of supplementation. [Evidence: C][11]
How much argan oil should I take daily?
Clinical studies used 25-30 ml (approximately 1.5-2 tablespoons) daily for health benefits. A meta-analysis found lipid improvements at 25 ml/day, while an osteoarthritis trial used 30 ml/day. Duration ranged from 2-8 weeks depending on the health goal. [Evidence: A][1] [Evidence: B][3]
🔬 How Does Argan Oil Work in Your Body?
Understanding how argan oil works helps explain its wide-ranging health effects. Think of argan oil's bioactive compounds as a team of specialized workers, each tackling a different aspect of cellular health.
The Antioxidant Defense System
Imagine your cells as a fortress constantly under attack from free radicals—unstable molecules that damage cellular structures. Argan oil acts like a well-trained defense force, deploying multiple antioxidant compounds to neutralize these threats. Research demonstrates that argan oil preserves the activity of key antioxidant enzymes including superoxide dismutase (SOD) and glutathione peroxidase (GPx), while reducing markers of oxidative damage like malondialdehyde (MDA). [Evidence: C][7]
At the molecular level, argan oil compounds activate the Nrf2 pathway—your body's master regulator of antioxidant responses. This triggers increased expression of protective enzymes including NQO1, HO-1, and catalase. [Evidence: D][9]
Anti-Inflammatory Mechanisms
Argan oil's unique phytosterols—schottenol and spinasterol—appear to play a key role in reducing inflammation. Cell studies show these compounds decrease intracellular reactive oxygen species (ROS) and nitric oxide (NO) levels while attenuating inflammatory markers triggered by bacterial compounds. [Evidence: C][8]
In animal models, argan oil's anti-inflammatory effects were comparable to diclofenac (a common NSAID) in short-term assessments. [Evidence: C][6] A 2025 review notes that argan oil inhibits the NF-κB pathway, a key driver of inflammatory responses in the body. [Evidence: D][13]
Lipid Metabolism Effects
The cholesterol-lowering effects of argan oil relate to its fatty acid profile—rich in oleic acid (omega-9) and linoleic acid (omega-6)—combined with its phytosterol content. Clinical studies confirm that 4 weeks of argan oil consumption improved lipid profiles by decreasing LDL cholesterol and triglycerides while increasing HDL cholesterol and vitamin E levels. [Evidence: B][2]
Preclinical research suggests argan oil may also support metabolic health by preventing blood pressure elevation and reducing fat accumulation, triglycerides, leptin, glucose, and insulin levels while increasing beneficial adiponectin. [Evidence: C][5]
Protective Effects Across Organs
A comprehensive review of argan oil's protective effects found evidence for reduced toxicity across multiple organ systems, including the liver, kidneys, brain, and immune system. These protective mechanisms involve antioxidant enhancement, inflammation modulation, and mitochondrial function support. [Evidence: D][10]
Traditional Moroccan use of argan oil has been validated by research showing that hand-pressed oil, with its higher polyphenol and tocopherol content, demonstrates superior anti-inflammatory properties compared to mechanically-pressed varieties. [Evidence: C][12]

Frequently Asked Questions
Can argan oil help with diabetes or blood sugar management?
Preclinical research provides preliminary support for metabolic benefits. In animal models of metabolic syndrome, argan oil reduced glucose levels, insulin, triglycerides, and leptin while increasing beneficial adiponectin—a hormone that helps regulate glucose levels and fatty acid breakdown. The study found argan oil outperformed corn oil in most metabolic parameters. [Evidence: C][5] However, these findings are from rat studies, and human clinical trials specifically examining argan oil's effects on blood sugar control in diabetic patients are limited. If you have diabetes, consult your healthcare provider before using argan oil as part of your management plan, and continue all prescribed treatments.
What nutrients are in argan oil?
Argan oil contains a unique combination of bioactive compounds that contribute to its health effects: * Fatty acids: Oleic acid (43-49%) and linoleic acid (29-36%) * Vitamin E: Particularly rich in γ-tocopherol * Phytosterols: Unique schottenol and spinasterol compounds * Polyphenols: Including ferulic acid and other phenolic compounds * Squalene: A natural antioxidant compound Research confirms argan oil's high polyphenol, sterol, and tocopherol content contributes to its antioxidant capacity. [Evidence: C][7]
Is culinary argan oil different from cosmetic argan oil?
Yes, there are important differences between culinary and cosmetic argan oil. Culinary argan oil is made from roasted argan kernels, giving it a distinctive nutty, toasted flavor suitable for consumption. It's the type used in all the clinical studies examining internal health benefits. Cosmetic argan oil is cold-pressed from raw, unroasted kernels and has a lighter color and milder scent. It's formulated for topical application on skin and hair, not for ingestion. Research validating traditional use found that extraction method affects polyphenol and tocopherol content, with hand-pressed oil showing higher levels. [Evidence: C][12] For health benefits through oral consumption, always choose food-grade culinary argan oil.
