Fish Oil and Ox Bile: what the published research says

PubMed indexes 3 records that name Fish Oil and Ox Bile 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.

Read this first

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 Ox Bile. 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

3 studies naming Fish Oil and Ox Bile.

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

Bile salts as semiochemicals in fish.

Chemical senses · 2014 · PMID 25151152

ReviewAnimal study

“Second, we consider the potential role of bile salts as semiochemicals in the contexts of detecting nearby fish, foraging, assessing risk, migrating, and spawning. Lastly, we suggest future studies on bile salts as semiochemicals further characterize release into the environment, behavioral responses by receivers, and directly test the biological contexts underlying olfactory sensitivity.”

Buchinger et al. · From the abstract

Names both Fish Oil and Ox Bile in its title.

Diversity of bile salts in fish and amphibians: evolution of a complex biochemical pathway.

Physiological and biochemical zoology : PBZ · 2010 · PMID 20113173

Research Support, N.I.H., ExtramuralResearch Support, U.S. Gov't, Non-P.H.S.Animal study

“Thus, the bile salt synthetic pathway has become longer and more complex throughout vertebrate evolution. Analysis of the evolution of bile salt synthetic pathways provides a rich model system for the molecular evolution of a complex biochemical pathway in vertebrates.”

Hagey et al. · From the abstract

Names both Fish Oil and Ox Bile in its title.

A novel self-micro-emulsifying delivery system (SMEDS) formulation significantly improves the fasting absorption of EPA and DHA from a single dose of an omega-3 ethyl ester concentrate.

Lipids in health and disease · 2017 · PMID 29037249

Clinical Trial

“PRF-021 is a novel SMEDS formulation of Omega-3-acid EE demonstrating a marked improvement in absorption of a single dose of EPA and DHA EE under fasted conditions. This allows adequate absorption of Omega-3 from the supplement without the requirement of a high-fat meal.”

Qin et al. · Authors' conclusion

Names Fish Oil and Ox Bile 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:

NutriStack

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, Ox Bile, 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.
