Fish Oil and Fucoxanthin: what the published research says

PubMed indexes 8 records that name Fish Oil and Fucoxanthin 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.

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Fish Oil and Fucoxanthin. 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.

The research

8 studies naming Fish Oil and Fucoxanthin.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Characterization of the produced electrospun fish gelatin nanofiber containing fucoxanthin.

Food science and biotechnology · 2022 · PMID 36778089

“Further, these nanofibers showed the antibacterial properties against bacteria. Based on the results, the fish gelatin nanofibers containing fucoxanthin can be proposed as a suitable coating for using in the food packaging industry.”

Azarshah et al. · From the abstract

Names both Fish Oil and Fucoxanthin in its title.

Differential responses in EPA and fucoxanthin production by the marine diatom Stauroneis sp. under varying cultivation conditions.

Biotechnology progress · 2021 · PMID 34337902

“The fucoxanthin yield was the highest when cells were subjected to blue LEDs (5.9 mg g-1 ), a fourfold increase compared to the nitrogen-limited treatment under white LEDs. These results indicate that a two-stage approach to the batch cultivation of this diatom can be used for enhancing the production of the high-value metabolites fucoxanthin and EPA post-stationary phase.”

Parkes et al. · From the abstract

Names both Fish Oil and Fucoxanthin in its title.

Dietary combination of fucoxanthin and fish oil attenuates the weight gain of white adipose tissue and decreases blood glucose in obese/diabetic KK-Ay mice.

Journal of agricultural and food chemistry · 2007 · PMID 17715888

Animal study

“These results suggest that dietary fucoxanthin decreases the blood glucose and plasma insulin concentration of KK- A(y) along with down-regulating TNFalpha mRNA. In addition, the combination of fucoxanthin and fish oil is more effective for attenuating the weight gain of WAT than feeding with fucoxanthin alone.”

Maeda et al. · From the abstract

Names both Fish Oil and Fucoxanthin in its title.

Dietary fish oil and Undaria pinnatifida (wakame) synergistically decrease rat serum and liver triacylglycerol.

The Journal of nutrition · 2002 · PMID 11925471

Animal study

“Because the decrease in the concentration of triacylglycerol in the liver was greatest when rats were fed wakame and fish oil at the same time (W + FO diet), we conclude that there was a synergistic process affecting fatty acid beta-oxidation in the liver. These results suggest that the simultaneous consumption of fish (fish oil) and wakame decreases the concentration of triacylglycerol in the serum and liver.”

Murata et al. · From the abstract

Names both Fish Oil and Fucoxanthin in its title.

Effect of carotenoids on gut health and inflammatory status: A systematic review of in vivo animal studies.

Critical reviews in food science and nutrition · 2024 · PMID 37450500

Systematic ReviewAnimal study

“This is the first systematic review to address the effects of carotenoids on gut health. Further studies are needed to better understand the effects of carotenoids on gut health.”

Silva Meneguelli et al. · From the abstract

Names Fish Oil and Fucoxanthin together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Fish Oil, Fucoxanthin, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
