Which is better, omega-3 or omega-7?

While omega-3 fatty acids have been widely researched for decades, a 2025 study highlighted the distinct metabolic and anti-inflammatory roles of omega-7. The question of which is better, omega-3 or omega-7, depends entirely on your specific health goals and needs, as these two fatty acids offer unique and complementary benefits.

Quick Summary

This guide compares omega-3 and omega-7 fatty acids, outlining their distinct benefits, sources, and functional differences. It provides a detailed comparison of their effects on heart health, skin, and metabolism to help you determine which fatty acid best suits your nutritional needs.

Key Points

• Essential vs. Non-Essential: Omega-3s are essential fatty acids and must be obtained from your diet, whereas omega-7s are non-essential but beneficial to consume.

• Primary Health Benefits: Omega-3s are known for broad systemic benefits, including heart health, brain function, and overall inflammation reduction. Omega-7s are primarily known for specialized benefits in skin hydration, mucous membrane health, and metabolic support.

• Dietary Sources: Omega-3s are abundant in fatty fish, flaxseed, and walnuts. Omega-7 is primarily found in sea buckthorn oil and macadamia nuts.

• Inflammation Management: Both fatty acids have anti-inflammatory effects, but omega-3s offer a powerful systemic reduction, while omega-7 provides localized support, especially for mucous membranes.

• Synergistic Action: For comprehensive wellness, many experts recommend ensuring adequate intake of both omega-3 and omega-7, as they offer complementary benefits rather than competing ones.

• Supplementation: Supplements often provide a blend of omegas, but vegetarian and vegan options are available, such as algae oil for omega-3 and plant-based sources like sea buckthorn oil for omega-7.

Omega-3 vs. Omega-7: Understanding the Core Differences

Omega-3 and omega-7 fatty acids differ fundamentally in their chemical structure and biological function. Omega-3s are essential polyunsaturated fatty acids (PUFAs) the body cannot produce. Omega-7s, specifically palmitoleic acid, are monounsaturated fatty acids (MUFAs) that the body can produce, though dietary intake is beneficial.

Synergistic Benefits: Combining Omega-3 and Omega-7

Omega-3 and omega-7 offer complementary benefits. Focusing on heart or brain health means prioritizing omega-3s, while addressing dry skin or metabolic concerns may benefit from adding omega-7. Many supplements now blend various fatty acids for broader support. A diet with fatty fish provides both. Vegetarians and vegans can find options in algae-based omega-3s and plant-based omega-7 sources like sea buckthorn oil. The best approach is ensuring adequate intake of both, based on individual needs. For more information, the National Institutes of Health Office of Dietary Supplements is a valuable resource.

Conclusion: A Complementary Relationship

Neither omega-3 nor omega-7 is inherently "better"; they serve different, valuable roles. Omega-3s are essential for broad systemic health, including heart and brain function, while omega-7s provide specialized support for skin and metabolic health. Optimal wellness often involves ensuring sufficient intake of both through diet or supplements. Consult a healthcare professional to personalize your approach.

The Takeaway

Omega-3 is essential for systemic health, while omega-7 targets skin and metabolism. They are complementary and can be taken together.

Important Note: Always consult a healthcare provider before starting any new supplement, especially with existing conditions or medications.

Frequently Asked Questions

Can I take omega-3 and omega-7 together?

Yes, you can take omega-3 and omega-7 supplements together. They have different, yet complementary, health benefits. Many supplements offer a blend of both fatty acids to provide a more comprehensive nutritional profile.

What is the primary difference between omega-3 and omega-7?

The main difference is their classification and function. Omega-3s are essential polyunsaturated fats vital for broad systemic health, while omega-7s are non-essential monounsaturated fats that offer specialized benefits for skin, mucous membranes, and metabolism.

Which omega is better for heart health?

Omega-3 is the more established and heavily researched fatty acid for heart health. It is proven to help lower triglycerides, reduce blood pressure, and decrease the risk of irregular heartbeats. Omega-7 can also support heart health by enhancing fat metabolism.

Which omega is better for skin health?

For targeted skin hydration and elasticity, omega-7 is often considered superior and is sometimes called the “beauty omega.” It actively promotes collagen production and protects the skin and mucous membranes. Omega-3s contribute to overall skin health through their anti-inflammatory effects.

Are omega-7 supplements necessary if the body can produce it?

While the body can produce omega-7, dietary intake through supplements or food sources like sea buckthorn oil can still be highly beneficial, especially for targeting specific concerns like dry skin or supporting metabolic health.

What are the best dietary sources for these fatty acids?

For omega-3, excellent sources include oily fish (salmon, sardines), flaxseed, and walnuts. For omega-7, the richest sources are sea buckthorn oil and macadamia nuts.

Do vegetarians and vegans have access to these omegas?

Yes. Vegetarians can get the ALA form of omega-3 from nuts and seeds. For direct EPA and DHA, algae-based omega-3 supplements are available. Plant-based omega-7 sources include sea buckthorn oil and macadamia nuts.
