Plant-based omega and the shift toward whole-food nutrition
Most plant-based omega sources cover omega-3 or omega-6. Omega-7 is rare in plants, and sea buckthorn is one of the few natural sources that carries it, alongside 3, 6 and 9, in a whole berry rather than an isolated capsule.
This article compares fatty acid sources for general education. It does not claim any product treats, cures or prevents disease.
The short answer
Plant-based omega sources are becoming more visible as an alternative to fish oil, but most only cover omega-3 or omega-6. Omega-7 palmitoleic acid is naturally rare across the plant kingdom, and sea buckthorn is one of the few sources where it occurs in meaningfully concentrated form, alongside omega 3, 6 and 9 in a single whole berry rather than an isolated capsule.

Why fish oil is not the only option anymore
Fish oil has long been the default omega-3 source, concentrated in EPA and DHA, the two marine forms most studied for general cardiovascular and cognitive research. Interest in plant-based alternatives has grown for several reasons: dietary preference, sustainability concerns around fish stocks, and a broader shift toward whole-food nutrition over isolated supplement capsules.
Not all plant omega is the same fatty acid
This is where the comparison gets specific. Flax and chia seeds are rich in ALA, a plant form of omega-3 that the body converts, inefficiently, into the EPA and DHA forms fish oil delivers directly. Algae oil is a marine-independent source that supplies DHA directly, without fish. Both are useful, well-studied options, but neither covers omega-7.
Omega-7, specifically palmitoleic acid, is naturally uncommon across the plant kingdom. It shows up in trace amounts in a handful of plants, but sea buckthorn berries and their oil are one of the few sources where it occurs in meaningfully concentrated form. That is part of why sea buckthorn draws research attention beyond its well-known vitamin C content, it is a rare plant source of a fatty acid usually associated with animal sources like macadamia oil or deep-sea fish.

Whole berry versus isolated capsule
There is a second axis to this shift beyond which fatty acid a source covers: whether it arrives as a whole food or an isolated extract. A whole-food puree made from the entire berry carries its full natural compound profile, fatty acids alongside vitamin C, flavonoids and more, eaten as food. A supplement capsule is engineered to deliver one nutrient at a concentrated, isolated dose. Both have a legitimate place in nutrition, but they are structurally different products, and Human Renaissance's puree sits in the whole-food category, not the isolated-supplement one.
The plant itself is worth noting too. Sea buckthorn used for compounds like these grows wild at high altitude on the Tibetan Plateau and across Inner Mongolia, frequently above 3,000 meters, conditions no backyard shrub experiences. That growing environment is part of the plant's story, not a claim about what eating the berry does inside the body.
Key takeaways
Plant omega, in three points
- Most plant sources are partial. Flax, chia and algae oil cover omega-3, not the full 3-6-7-9 range.
- Omega-7 is genuinely rare in plants. Sea buckthorn is one of the few natural sources carrying it in meaningful concentration.
- Whole food versus isolated capsule is a separate, equally important axis from which fatty acid a source covers.

From the journal shelf
Sea Buckthorn Puree
A whole-food sea buckthorn puree with 190+ naturally occurring compounds, omega 3-6-7-9, 201 mg vitamin C per serving and 0 g added sugar. It is a nutritional food, not a supplement, and not the same as the isolated berry extract studied in the research discussed above.
- 190+ compounds
- Omega 3-6-7-9
- 201 mg vitamin C
- 0 g sugar
190+ naturally occurring compounds including omega 3-6-7-9, 201 mg vitamin C per serving and 0 g added sugar, made from the whole berry as a nutritional food, not a supplement.
What is plant-based omega?
Plant-based omega refers to omega fatty acids sourced from plants rather than fish or marine oil. Most plant sources are rich in omega-3 or omega-6, but very few plants naturally carry meaningful omega-7, which is why sea buckthorn is notable.
How does plant-based omega compare to fish oil?
Fish oil is concentrated in EPA and DHA. Plant sources vary: flax and chia carry ALA omega-3, algae oil supplies DHA directly, and sea buckthorn is unusual for carrying omega-7 alongside 3, 6 and 9. Each source has a different fatty acid profile.
Why is omega-7 harder to find in plants?
Omega-7 palmitoleic acid is naturally uncommon in the plant kingdom. Sea buckthorn berries and their oil are one of the few sources where it occurs in meaningfully concentrated form.
What does whole-food nutrition mean, compared to a supplement?
Whole-food nutrition means eating a food close to its natural, minimally processed state, rather than an isolated capsule engineered to deliver one nutrient. Both have a place in nutrition science, but they are structurally different products.
Is sea buckthorn a supplement or a food?
Sea buckthorn puree, made from the whole berry, is a nutritional food product, not an isolated supplement capsule. It is eaten as part of a diet, carrying its full natural mix of compounds.
