The Omega-7 Oil Powerhouses
When seeking the richest plant-based sources of omega-7, two oils stand out: sea buckthorn and macadamia nut oil. While other oils like olive and avocado contain small amounts, their concentrations are significantly lower.
Sea Buckthorn Oil: Nature's Omega-7 Champion
Sea buckthorn oil, from the berries and seeds of the sea buckthorn shrub, is known for its high concentration of omega-7 (palmitoleic acid). Some extracts have over 30% omega-7. It also contains other omegas (3, 6, 9) and antioxidants.
- Source: Extracted from the pulp and seeds of the sea buckthorn berry.
- Benefits: Supports skin hydration, dry eyes, and digestive and cardiovascular health.
- How to use: Available as capsules or topical oil.
Macadamia Nut Oil: The Delicious Option
Macadamia nut oil is another source of omega-7, with up to 36% palmitoleic acid. It has a mild flavor and is versatile in cooking.
- Source: Cold-pressed from macadamia nuts.
- Benefits: Supports skin elasticity and may help balance cholesterol.
- How to use: Use in cooking, as a drizzle, or on skin.
The Health Benefits of Omega-7 Fatty Acids
Omega-7s, particularly palmitoleic acid, are monounsaturated fats linked to several health benefits. While the body produces some, dietary intake provides concentrated benefits.
Supporting Skin and Mucous Membranes
Omega-7 significantly benefits skin and mucosal health. It's a natural skin component and improves hydration, elasticity, and appearance. It's used in skincare and as a supplement for dry eyes, dry mouth, and vaginal dryness.
Aiding Metabolic and Cardiovascular Health
Research suggests omega-7's role in metabolic regulation. It may benefit insulin sensitivity, blood lipid levels, and appetite control. Diets rich in omega-7 may increase HDL and lower LDL cholesterol.
Comparison of Omega-7 Oil Sources
Here's a comparison to help choose the best oil for you.
| Feature | Sea Buckthorn Oil | Macadamia Nut Oil |
|---|---|---|
| Omega-7 Concentration | Very high (up to 38% palmitoleic acid) | High (up to 36% palmitoleic acid) |
| Flavor Profile | Distinctive, tart, or earthy taste | Mild, buttery, and slightly nutty |
| Culinary Use | Best uncooked | Excellent for low-to-medium heat cooking |
| Antioxidant Content | Exceptionally high | Rich in antioxidants |
| Full Spectrum Omegas | Often a source of omega-3, 6, and 9 | Contains omega-6 and 9 |
| Primary Use Cases | Supplements for mucosal dryness, skin, and internal health | Culinary use, topical skin care, and dietary supplementation |
Conclusion
Sea buckthorn oil and macadamia nut oil are the primary sources of omega-7. Sea buckthorn oil offers the highest concentration for targeted benefits, while macadamia nut oil is a delicious dietary source. Both provide significant health benefits from palmitoleic acid. Incorporating either into your routine through supplements, cooking, or topical use can boost your intake. Choose high-quality, organic, and cold-pressed oils for maximum benefit.

Frequently Asked Questions
Which oil is the single best source of omega-7?
Sea buckthorn oil, particularly from the berry pulp, is considered the richest natural source of omega-7 (palmitoleic acid).
Can I get omega-7 from fish oil?
Some fatty fish and fish oils contain omega-7, but in much lower concentrations than sea buckthorn and macadamia nut oils.
Is omega-7 an essential fatty acid?
No, the body can produce omega-7 from other fatty acids. However, dietary intake of concentrated sources can be beneficial.
Are there any side effects from taking omega-7 oil?
Most people have no side effects from sea buckthorn omega-7. High doses might cause mild stomach upset. Follow recommended dosages and consult a doctor if concerned.
How does omega-7 benefit skin health?
Omega-7 fatty acids moisturize and regenerate skin and mucous membranes. They improve elasticity, hydration, and can help with wound healing and reducing wrinkles and dryness.
Is macadamia nut oil a good cooking oil for omega-7?
Yes, macadamia nut oil is an excellent culinary source of omega-7. It's suitable for low-to-medium heat cooking, dressings, and topical skin application.
How is sea buckthorn oil processed to get omega-7?
