Quick Summary
Sea Buckthorn is one of very few plant sources of omega-7 (palmitoleic acid)—a fatty acid that supports mucous membrane and skin health. Contains 10x more vitamin C than oranges. A premium functional ingredient indicating thoughtful formulation, particularly in skin/coat products.
What Is Sea Buckthorn?
Bright orange berry from sea buckthorn shrub, exceptionally rich in omega-7 fatty acids, vitamin C, antioxidants, and nutrients.
Compare to Similar Ingredients
- vs. blueberries: Both are antioxidant-rich berries. Sea buckthorn is unique for omega-7 fatty acids and exceptional vitamin C content (10x more than oranges), while blueberries focus on anthocyanins and cognitive support.
- vs. fish oil: Sea buckthorn provides rare omega-7 plus omega-3, 6, and 9 in one plant source, while fish oil specializes in marine omega-3s (EPA/DHA). Both support skin and coat but through different mechanisms.
- vs. pumpkin: Both support digestive health. Sea buckthorn provides omega-7 for mucous membrane health plus antioxidants, while pumpkin offers fiber and beta-carotene. Sea buckthorn is more nutrient-dense but less common.
Why Manufacturers Add Sea Buckthorn to Dog Food
Sea buckthorn is used in premium dog supplements for its rare omega-7 (palmitoleic acid) content, which supports skin and mucous membrane integrity, alongside an extraordinarily high vitamin C concentration and a full spectrum of omega-3, 6, 7, and 9 fatty acids in a single plant source.
- Rare source of omega-7 (palmitoleic acid) for skin and mucous membrane health
- Extremely high in vitamin C and antioxidants
- Supports skin, coat, and digestive health
- Anti-inflammatory properties
- Omega-3, 6, 7, and 9 fatty acids in one source
Sea Buckthorn Quality Considerations
When evaluating sea buckthorn in dog products, it's important to understand antioxidant content, phytonutrients, and whole food nutrition. Sea buckthorn is unusually nutrient-dense — it contains vitamins C and E, carotenoids, and omega-7 fatty acids (palmitoleic acid) in meaningful concentrations. Unlike most plant ingredients in pet food, it can contribute real nutritional value even at modest inclusion rates.
Superfood ingredient with exceptional nutritional profile. One of the only plant sources of omega-7 fatty acids. Particularly beneficial for skin, coat, and digestive tract lining. Quality varies by berry vs. seed oil and extraction method. Premium ingredient that justifies higher cost.
Sea Buckthorn: What the Research Shows
Sea buckthorn (Hippophae rhamnoides) is a nutrient-dense berry rich in vitamins, antioxidants, and omega fatty acids. It has traditional use in herbal medicine and is increasingly included in pet supplements for skin, immune, and digestive support.
Key Research Findings
- Sea buckthorn is exceptionally rich in vitamin C (higher than oranges), vitamin E, carotenoids, and flavonoids with antioxidant properties
- Contains a rare plant source of omega-7 fatty acids (palmitoleic acid) alongside omega-3, -6, and -9, supporting skin and mucous membrane health
- Research suggests potential benefits for skin health, wound healing, and immune function
- May support digestive health through anti-inflammatory effects on mucous membranes
- Most research is in humans or laboratory studies; canine-specific clinical evidence is limited
- Oil and berry forms have different nutrient profiles; whole berry includes fiber and additional phytonutrients
- Generally considered safe based on traditional use and preliminary research
Evidence Level: Moderate evidence for antioxidant and skin-supporting benefits based on nutrient composition and preliminary research. Limited canine-specific studies. Safe based on traditional use.

It's typically found in skin/coat formulas.
Where should sea buckthorn appear on the ingredient list?
Sea buckthorn typically appears in positions 15-30 in specialty supplements and skin/coat formulas. In general pet foods where it's added as a premium ingredient, expect positions 25-40. Its positioning depends on the form used - oil concentrates appear lower than whole berry inclusions due to potency differences.
Is sea buckthorn necessary in dog food?
Sea buckthorn is not nutritionally essential - dogs can be healthy without it.
