Omega-7: The Rare Fatty Acid and Where to Get It
Omega-7 is a monounsaturated fatty acid (palmitoleic acid) that is uncommon in everyday foods. Unlike omega-3 and omega-6, omega-7 is found in meaningful quantities in only a handful of sources. Sea buckthorn berries are one of the richest plant sources. The human body can produce small amounts of omega-7, but dietary sources remain the most reliable way to maintain adequate intake.
Why omega-7 is rare in the diet
Most dietary fat discussions focus on omega-3 and omega-6. Omega-7 receives less attention partly because the research base is smaller. Interest has grown as researchers examine its role in mucosal tissue integrity — the lining of the gut, skin, and mucous membranes. Omega-7 is not an essential fatty acid in the strict sense, but dietary sources provide concentrations the body cannot efficiently self-produce.
Best food sources of omega-7
| Source | Type | Omega-7 level | Notes |
|---|---|---|---|
| Sea buckthorn | Plant | Very high | Also provides omega-3, 6, 9 and vitamin C |
| Macadamia nuts | Plant | High | Rich in monounsaturated fats |
| Anchovies | Animal | Moderate | Also contains omega-3 |
| Sardines | Animal | Moderate | Also contains omega-3 |
For people who do not eat fish, sea buckthorn is the most concentrated plant-based omega-7 source. It also contains omega-3, 6 and 9 simultaneously — rare among plant foods.
Sea buckthorn as a plant source of omega-7
Sea buckthorn pulp is notable because it contains all four omega fatty acids simultaneously. Satvik India sources sea buckthorn from the Leh-Ladakh GI-Tag region of India — a Geographical Indication that legally recognises the region's berries as a distinct, quality-assured product.

How much omega-7 per day
There is no established Recommended Daily Intake for omega-7. Research on omega-7 supplementation has used varying doses. For sea buckthorn pulp as a food supplement, a typical daily serving is 15–30 ml. If you are considering supplementation for a specific health goal, speak to a registered dietitian or doctor.
Frequently asked questions
What is omega-7?
Omega-7 is a monounsaturated fatty acid (palmitoleic acid) found in small amounts in the human body and in certain foods. Sea buckthorn and macadamia nuts are among the richest sources. Unlike omega-3 and omega-6, it is not classified as essential, but is found in very few plant foods at meaningful concentrations.
What is the best source of omega-7?
Sea buckthorn berries are the richest plant source of omega-7. They also contain omega-3, 6 and 9 simultaneously. Macadamia nuts are the next best plant source. Among animal sources, anchovies and sardines contain moderate omega-7 alongside omega-3.
Is omega-7 better than omega-3?
They serve different functions. Omega-3 has decades of clinical research for cardiovascular health. Omega-7 research is newer. They are not in competition — sea buckthorn is distinctive because it provides both from a single plant source.
Does sea buckthorn have omega-7?
Yes. Sea buckthorn is one of the richest plant sources of omega-7. It also contains omega-3, 6 and 9 — making it unusual among plant foods for providing all four omega fatty acids simultaneously.
