Anthocyanins (Bilberry Extract) and Fish Oil: what the published research says
PubMed indexes 8 records that name Anthocyanins (Bilberry Extract) and Fish Oil together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Anthocyanins (Bilberry Extract) and Fish Oil. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
8 studies naming Anthocyanins (Bilberry Extract) and Fish Oil.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
Biomedical research (Tokyo, Japan) · 2011 · PMID 22199129
Randomized Controlled Trial
“Furthermore, a score of mental fatigue was improved after 4 weeks of supplementation, and no side effects were observed after the 4-week supplementation and a 2-week washout period in the Active group. These results suggest that dietary supplementation with the combination of omega-3 fatty acid-rich fish oil, bilberry extract, and lutein may safely improve subjective symptoms of asthenopia and mental fatigue in humans.”
Names both Anthocyanins (Bilberry Extract) and Fish Oil in its title.
International journal of biological macromolecules · 2025 · PMID 40865820
Animal study
“Among the treatments, the F30 film demonstrated a quick response to pH variations associated with fish spoilage, with a noticeable transition from translucent to an opaque yellowish. These results demonstrate the feasibility of using CAE in intelligent and sustainable systems for monitoring fish freshness.”
Names both Anthocyanins (Bilberry Extract) and Fish Oil in its title.
International journal of biological macromolecules · 2024 · PMID 39147341
Animal study
“When used on fresh carp, the antibacterial indicator card not only indicated the freshness of the carp but also extended the best before date of the fish meat by 1-2 days. The indicator exhibited the most pronounced color transformation and optimal freshness indication performance when the mass fraction of anthocyanins was 2 %.”
Names both Anthocyanins (Bilberry Extract) and Fish Oil in its title.
“These data demonstrate for the first time the direct effects of AvailOm® on resistance arteries. The evidence that the combination of specific vasoactive anthocyanins and AvailOm® further enhanced the vasculoprotective properties of these compounds, may offer new promising perspectives for preventing the onset of cardiovascular and cerebrovascular events.”
Names both Anthocyanins (Bilberry Extract) and Fish Oil in its title.
Journal of agricultural and food chemistry · 2009 · PMID 19845348
Animal study
“Percentage of degradation of anthocyanins and anthocyanidins in jams is highly dependent on degrees Brix: 64-76 degrees Brix led to 20-30% degradation, whereas 80 degrees Brix resulted in degradation between 50 and 60%. Percentage of degradation of anthocyanins in whole blueberries cooked in stuffed fish ranged between 45 and 50%, however, for anthocyanidins, the percentage of degradation was significantly lower, between 12 and 30%, indicating that this cooking procedure can…”
Names both Anthocyanins (Bilberry Extract) and Fish Oil in its title.
Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.
