Argan Oil: Uses, Benefits, and Precautions

Argan oil, derived from the kernels of the native Moroccan argan tree (Argania spinosa), is a natural oil rich in fatty acids and antioxidants. It has a wide range of applications, including culinary use and as an ingredient in skin care and cosmetic products. However, before diving into the potential uses and benefits of argan oil, it's important to consider some key points.

Supplement Safety

In the United States, dietary supplements are not subject to the same rigorous regulations as drugs, meaning they aren't FDA-approved for safety and effectiveness before hitting the market. To ensure the quality of a supplement, it's advisable to opt for products tested by reputable third-party organizations like USP, ConsumerLab, or NSF.org. Nonetheless, even with third-party testing, safety and effectiveness can vary among individuals. Therefore, it's crucial to consult with your healthcare provider before taking any supplements, especially if you are on other medications.

Supplement Facts

Argan oil contains several active ingredients, including tocopherols (vitamin E), phytosterols, polyphenols, squalene, and various fatty acids like oleic and linoleic acid. It also contains melatonin and coenzyme Q10. This natural oil goes by alternate names such as Argan nut oil, argania spinosa kernel oil, argania sideroxylon oil, lyciodes candolleanum oil, lyciodes spinosum oil, and sideroxylon argan oil. It is legally available over the counter as a supplement in the U.S., with a suggested dose of 25 milliliters by mouth or ten drops applied to the skin daily for eight weeks. Generally, it is well-tolerated.

Uses of Argan Oil

Supplement usage should be tailored to individual needs and should always be discussed with a healthcare professional. It's important to note that no supplement is intended to cure, treat, or prevent diseases. Argan oil has a variety of cosmetic and therapeutic applications and is also a heart-healthy polyunsaturated oil used in cooking. However, while there is some evidence supporting its benefits in skin care, high cholesterol, and knee osteoarthritis, more scientific research is needed to substantiate these claims.

May Counter Effects of Aging in Skin

Argan oil's high antioxidant content, including oleic and linoleic acid, suggests it may combat aging by neutralizing harmful free radicals. Studies indicate that both oral and topical application of argan oil improved skin hydration and elasticity, particularly in postmenopausal women. Nevertheless, these studies involved small sample sizes and lacked placebo control groups, necessitating further research through randomized controlled trials.

May Lower Cholesterol

A systematic review revealed that argan oil supplementation for at least two weeks had positive effects on cholesterol levels. It reduced total cholesterol, LDL ("bad") cholesterol, and triglycerides while increasing HDL ("good") cholesterol levels. Larger clinical trials are needed to conclusively determine its impact on heart health.

May Improve Knee Osteoarthritis

A study involving people with knee osteoarthritis found that daily consumption of argan oil for eight weeks resulted in improved pain relief, increased function, and enhanced walking distance. However, more extensive research is required before argan oil can be recommended as a standard treatment.

Additional Uses

Argan oil has been studied for various conditions, including diabetes, metabolic syndrome, depression, kidney and liver diseases, and cancer. However, the scientific evidence supporting these applications is limited, primarily based on animal studies, and further research is essential to validate these claims.

Side Effects and Precautions

While argan oil is generally considered safe for topical and oral use, it may cause contact dermatitis in some individuals. Severe side effects are rare, with only one reported case of anaphylaxis associated with argan oil. People with oily skin are advised to avoid oil-based skin products like argan oil.

Dosage and Interactions

Always consult your healthcare provider before taking any supplements, as there are no established guidelines for argan oil dosage. It is worth noting that argan oil may contain tocopherols, a form of vitamin E, which could potentially interact with blood thinners like warfarin, increasing the risk of bleeding.

Storing Argan Oil

To preserve the quality of argan oil, store it in a dark bottle in a cool room, away from direct sunlight. Discard it after one year or according to the manufacturer's recommendations.

Similar Supplements

Several other plant oils and supplements are believed to have anti-aging and osteoarthritis benefits, including olive oil, sunflower seed oil, coconut oil, soybean oil, peanut oil, sesame oil, avocado oil, jojoba oil, almond oil, bitter apricot oil, rose hip oil, German chamomile oil, and shea butter. However, it is crucial to consult your healthcare provider before trying any of these supplements.

Sources and Quality Assurance

Argan oil is available as a cooking oil, cosmetic ingredient, and dietary supplement. When choosing a supplement, opt for those verified by third-party organizations like USP, ConsumerLab, or NSF.org. These agencies ensure label accuracy and product quality, but it's essential to remember that such quality assurance does not guarantee safety or effectiveness.

In conclusion, argan oil has potential benefits in various applications, but more extensive scientific research is required to confirm its efficacy fully. Always prioritize consultation with a healthcare professional before incorporating supplements into your routine, and be mindful of potential interactions and side effects. Additionally, consider other natural oils and supplements that may offer similar benefits.
