The first time I stood in a Canadian health food aisle staring at a bottle of fish oil, I remember thinking, "There has to be a way to get these nutrients without the fishy burps." You know the ones—that lingering aftertaste that reminds you of a pier at noon.
For years, we’ve been told that if we want healthy skin, a sharp brain, and a happy heart, we have to look to the ocean. But lately, I’ve found myself reaching for something much brighter, much more orange, and—honestly—much more pleasant.
We’re talking about sea buckthorn. Specifically, the wild-harvested variety that grows in the harshest climates, concentrating its power into tiny, tart berries. If you’ve been loyal to your fish oil but feel like something is missing (or you're just tired of the heavy processing), it's time we talk about how these two stack up.
More Than Just "Plant-Based Fish Oil"
Comparing sea buckthorn to fish oil isn't exactly apples-to-apples. It’s more like comparing a high-performance multivitamin to a specialized supplement.
Fish oil is legendary for its Omega-3 content (EPA and DHA). We need those for brain health and reducing systemic inflammation. But sea buckthorn is the overachiever of the plant world. It doesn't just give you one Omega; it brings the whole family to the party: Omegas 3, 6, 9, and the elusive Omega-7.
Omega-7 (palmitoleic acid) is the secret sauce here. While fish oil focuses on the "big picture" of inflammation, Omega-7 is like a targeted repair crew for your mucous membranes and skin. It’s why people swear by it for dry eyes, digestive health, and that "lit-from-within" skin glow.
I started adding Human Renaissance wild-harvested sea buckthorn puree to my morning smoothies about six months ago, and the difference in my skin hydration during a dry Canadian winter was enough to make me a believer.
The Vitamin C Heavyweight Champion
If we’re going to talk about vitamin C, we have to talk about sea buckthorn. Most people think of oranges when they need an immune boost. But per 100 grams, sea buckthorn berries can contain anywhere from 400mg to 800mg of vitamin C—that’s roughly 12 times more than an orange.
Fish oil, by its nature, contains zero vitamin C.
When you choose a berry-based source like sea buckthorn, you aren't just getting healthy fats; you're getting a massive hit of antioxidants that help your body actually use those fats while protecting your cells from oxidative stress. It’s a synergistic relationship that a refined oil just can’t replicate.
What the Science Says
I’m a big fan of "trust but verify." We don't just want to feel better; we want to know why we feel better.
1. Cardiovascular Support
While fish oil is the gold standard for heart health, sea buckthorn is proving to be a formidable peer. A study published in International Journal of Food Sciences and Nutrition highlighted that sea buckthorn berries have a positive impact on risk factors for cardiovascular disease, including lipid metabolism and platelet aggregation. You can read the full review on PubMed here.
2. Skin and Mucosal Healing
This is where sea buckthorn truly leaves fish oil in the dust. Because it contains such a high concentration of flavonoids and fatty acids, it acts as a "multi-target" anti-inflammatory agent. Research suggests it helps restore the skin barrier and even helps with internal "dryness" (think gut health and dry eyes). A recent 2025 review in Frontiers in Pharmacology breaks down exactly how sea buckthorn helps with tissue repair and inflammatory cascades.
The Sustainability Factor: Wild-Harvested vs. Farmed
I often think about where my supplements come from. The fish oil industry is massive, and even "sustainable" brands put a significant strain on marine ecosystems. Plus, fish oil requires intense heat and chemical processing to remove heavy metals and toxins like mercury.
On the other hand, sea buckthorn—especially when it’s wild-harvested—is a miracle of permaculture. These hardy shrubs actually help fix nitrogen in the soil and prevent erosion.
When you use Human Renaissance wild-harvested sea buckthorn puree, you’re getting a product that hasn’t been stripped down or "purified" with harsh chemicals. It’s the whole fruit, which means you get the fiber, the pulp, and the bioactive compounds that are often lost in clear oils.

The Breakdown: Sea Buckthorn vs. Fish Oil
| Feature | Human Renaissance Sea Buckthorn Puree | Standard Fish Oil Supplements |
| Omega Profile | Full Spectrum: Omegas 3, 6, 9 + Omega-7 | Primarily Omega-3 (EPA & DHA) |
| Vitamin C Content | Extremely High (12x more than oranges) | None |
| Key Benefit | Skin hydration, mucosal health, & immunity | Brain health & systemic inflammation |
| Flavor Profile | Tart, citrusy, and bold | Neutral to "fishy" (often causes burps) |
| Processing | Minimally processed, wild-harvested fruit | Heavily refined, deodorized, and distilled |
| Antioxidants | Loaded with Flavonoids & Phenols | Usually none (unless added synthetically) |
| Sustainability | Carbon-sequestering wild shrubs | Potential strain on marine ecosystems |
Why the "Full Spectrum" Matters
When you look at that table, the Omega-7 and Vitamin C are the real "aha!" moments. While fish oil is a specialist focusing on heart and brain inflammation, sea buckthorn acts more like a generalist that specializes in your body’s "infrastructure"—your skin, your gut lining, and your immune response.
Using the Human Renaissance wild-harvested sea buckthorn puree means you aren't just getting an isolated fat; you're getting the co-factors that nature intended to come with it. It’s the difference between eating a whole orange and taking a vitamin C tablet—the "whole food" version is almost always more bioavailable.
How to Choose from Options
If you’re dealing with a specific brain-health issue where high doses of DHA are required, fish oil still has its place. But for the average person looking for better skin, a stronger immune system (thanks to that vitamin C), and a sustainable way to fight inflammation, sea buckthorn is the winner.
The best part? You don't have to swallow a giant, plastic-feeling pill. I love the ritual of the puree. It’s tart, bold, and feels like a real food because it is a real food. Adding a spoonful of Human Renaissance wild-harvested sea buckthorn puree to a bowl of yogurt or a glass of sparkling water is a much more vibrant way to start the day than chasing a pill with coffee.

Frequently Asked Questions
Q: Is sea buckthorn better than fish oil for dry eyes?
A: Many people find sea buckthorn more effective because of the Omega-7 content, which specifically targets the lubrication of mucous membranes. While fish oil (Omega-3) helps with general inflammation, sea buckthorn works on the "moisture" side of the equation.
Q: Can I take both?
A: Absolutely. They don’t "clash." However, many people find that once they switch to a high-quality sea buckthorn puree, they no longer feel the need for a separate fish oil supplement because of the broad-spectrum omegas provided by the berry.
Q: What does it taste like?
A: Imagine a cross between a very tart orange and a passionfruit, with a slightly "creamy" finish because of the natural oils. It’s a zingy wake-up call for your taste buds!
Q: Does it have more Vitamin C than supplements?
A: Because the vitamin C in sea buckthorn is food-based, it comes with bioflavonoids that help your body absorb it more efficiently than synthetic ascorbic acid found in many cheap supplements.
