What Exactly is Omega-7?
Omega-7 fatty acids are a group of monounsaturated fats, with palmitoleic acid being the most prominent. Unlike omega-3 and omega-6, omega-7 is not considered an "essential" fatty acid, as the human body can produce it endogenously. However, obtaining it through dietary sources or supplementation is thought to offer significant health benefits. Interest in omega-7 is growing due to research linking it to improvements in skin hydration, metabolic function, and inflammation. Two main forms are available on the market: whole-food sources like sea buckthorn oil and purified palmitoleic acid supplements. The key differences lie in their composition, concentration, and potential effects.
Natural Omega-7 from Sea Buckthorn Oil
Sea buckthorn oil, derived from the berries of the Hippophae rhamnoides plant, is a renowned source of omega-7. Its use dates back centuries in traditional Ayurvedic and Chinese medicine for its healing properties. It is an excellent whole-food option for those who prefer their nutrients in their natural state.
Benefits of Sea Buckthorn Oil
- Comprehensive Nutrient Profile: In addition to omega-7 (palmitoleic acid), sea buckthorn oil provides a complete spectrum of omega fatty acids (3, 6, and 9) along with a rich supply of vitamins (C and E), carotenoids, and other antioxidants. This synergistic blend supports overall wellness beyond just omega-7's effects.
- Exceptional for Skin and Mucous Membranes: Due to its unique composition, sea buckthorn oil is particularly effective for soothing and moisturizing skin, eyes, and other mucous membranes. It is often used to combat dry skin, eczema, and to aid in wound healing.
- Anti-inflammatory Properties: The oil's potent antioxidant content contributes to its anti-inflammatory effects.
Drawbacks of Sea Buckthorn Oil
- Palmitic Acid Content: As a whole-food source, sea buckthorn oil naturally contains palmitic acid, a saturated fat that some research suggests may have pro-inflammatory effects. The presence of this fatty acid could potentially counteract some of the benefits of palmitoleic acid, especially in certain individuals.
- Varying Concentration: The concentration of omega-7 can vary depending on the specific product, processing method, and source of the berries. High-quality extraction methods, like supercritical CO2 extraction, are necessary to preserve the potency of the oil.
Purified Palmitoleic Acid Supplements
Purified omega-7 supplements are refined concentrates of palmitoleic acid, often sourced from fish oil (like anchovies). The purification process removes palmitic acid, resulting in a product with a high concentration of the beneficial omega-7 fatty acid.
Benefits of Purified Palmitoleic Acid
- Targeted Effects: The main advantage is the high concentration of palmitoleic acid with the saturated palmitic acid removed. This allows for a more targeted therapeutic effect, particularly concerning metabolic health.
- Supports Metabolic Health: Purified omega-7 has been shown to support healthy cholesterol levels (increasing HDL and lowering LDL), promote a healthy inflammatory response, and improve insulin sensitivity.
- Consistent Potency: Unlike natural oils, purified supplements offer a standardized and consistent dosage of palmitoleic acid per serving.
Drawbacks of Purified Palmitoleic Acid
- Lacks Additional Nutrients: Purified supplements lack the wide array of complementary vitamins, antioxidants, and other omega fatty acids found in whole-food sources like sea buckthorn oil.
- Less Beneficial for Skin: While purified omega-7 has benefits, it does not offer the same comprehensive support for skin and mucous membranes as the whole-food profile of sea buckthorn oil.
Comparison: Sea Buckthorn Oil vs. Purified Palmitoleic Acid
To help determine what is the best form of omega-7 for your needs, here is a direct comparison.
| Feature | Purified Palmitoleic Acid | Sea Buckthorn Oil (High-Quality) |
|---|---|---|
| Source | Fish Oil (e.g., Anchovies) | Sea Buckthorn Berries |
| Palmitic Acid | Removed | Present, but balanced with other nutrients |
| Concentration | High, standardized palmitoleic acid | High, but part of a whole-food complex |
| Additional Nutrients | Often fortified with omega-3s | Rich in Omegas 3, 6, 9; Vitamins C, E; antioxidants |
| Primary Benefits | Targeted metabolic, inflammatory, and cardiovascular support | Broad skin, mucous membrane, and wellness support |
| Purity | High, with undesired fats removed | Dependent on extraction process and brand |
How to Choose the Right Form of Omega-7
The decision between a purified supplement and a whole-food oil depends on your specific health goals.
For those primarily seeking metabolic support, such as improving cholesterol levels, insulin sensitivity, and managing internal inflammation, purified palmitoleic acid is often the superior choice. The removal of palmitic acid ensures you are only ingesting the beneficial omega-7 without potential mitigating saturated fats.
For individuals targeting skin, eye, or mucous membrane health, high-quality sea buckthorn oil is the best form of omega-7. The comprehensive nutrient profile, including other omegas and antioxidants, provides a more holistic approach to cellular hydration and repair.
Ultimately, a healthy diet rich in nuts, seeds, and oily fish provides a foundation for good fatty acid intake, but targeted supplementation may be necessary to achieve specific health outcomes. Consulting with a healthcare provider can help determine the best approach for your individual needs.

Conclusion
There is no single "best" form of omega-7 for everyone, as the ideal choice hinges on your specific wellness objectives. Purified supplements offer targeted, high-potency palmitoleic acid for metabolic and cardiovascular support. In contrast, whole-food sea buckthorn oil provides a broader, nutrient-rich profile that is exceptionally beneficial for skin and mucosal health. By understanding the distinct advantages of each form, you can make an informed decision and effectively incorporate this powerful fatty acid into your routine.
