Atorvastatin and Fish Oil: what the published research says

PubMed indexes 8 records that name Atorvastatin 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.

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 Atorvastatin 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.

The research

8 studies naming Atorvastatin and Fish Oil.

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

Pharmacokinetic Comparison Between a Fixed-Dose Combination of Atorvastatin/Omega-3-Acid Ethyl Esters and the Corresponding Loose Combination in Healthy Korean Male Subjects.

Drug design, development and therapy · 2024 · PMID 38352172

Randomized Controlled Trial43 participants

“The FDC of atorvastatin and omega-3-acid ethyl esters showed comparable PK characteristics to the corresponding loose combination, offering a convenient therapeutic option for the treatment of dyslipidemia.”

Khwarg et al. · Authors' conclusion

Names both Atorvastatin and Fish Oil in its title.

Atorvastatin in Factorial with Omega-3 EE90 Risk Reduction in Diabetes (AFORRD): a randomised controlled trial.

Diabetologia · 2009 · PMID 19002433

Randomized Controlled Trial732 participants

“Many community-based diabetic patients without known CVD remain at high CVD risk despite statin treatment and require additional risk-reduction strategies. The impact of omega-3 EE90 on CVD risk will remain uncertain until clinical endpoint trial results are available.”

Holman et al. · Authors' conclusion

Names both Atorvastatin and Fish Oil in its title.

Atorvastatin remodels lipid distribution between liver and adipose tissues through blocking lipoprotein efflux in fish.

American journal of physiology. Regulatory, integrative and comparative physiology · 2023 · PMID 36572553

Animal study

“In general, atorvastatin induced the remodeling of lipid distribution between liver and adipose tissues through blocking VLDL efflux from the liver to adipose tissue of fish. Our results provide a novel regulatory pattern of cholesterol metabolism response caused by atorvastatin in fish, which is distinct from mammals: cholesterol inhibition by atorvastatin activates hepatic cholesterol synthesis and inhibits its efflux to maintain cholesterol homeostasis, consequently…”

Li et al. · From the abstract

Names both Atorvastatin and Fish Oil in its title.

Pharmacokinetic Interaction between Atorvastatin and Omega-3 Fatty Acid in Healthy Volunteers.

Pharmaceuticals (Basel, Switzerland) · 2022 · PMID 36015110

37 participants

“The GMRs (90% Cis) for the co-administration at steady state of atorvastatin, 2-OH-atorvastatin, DHA, and EPA were 1.150 (0.990-1.335), 1.301 (1.2707-1.1401), 0.320 (0.243-0.422), and 0.589 (0.487-0.712), respectively. The 90% CIs for most primary endpoints were outside the range of typical bioequivalence, indicating a pharmacokinetic interaction between atorvastatin and omega-3.”

Kim et al. · From the abstract

Names both Atorvastatin and Fish Oil in its title.

Omega-3 Fatty Acid Based Nanolipid Formulation of Atorvastatin for Treating Hyperlipidemia.

Advanced pharmaceutical bulletin · 2019 · PMID 31380253

“Anti-hyperlipidemic study showed a significant reduction in LDL and TG levels in serum with the orally administered Omega-3 fatty acid based AT loaded NLCs when compared to marketed formulation. Conclusion: The results demonstrated that the omega-3 fatty acid based NLC has the potential to be a promising nanomedicine for the treatment of hyperlipidemia.”

Sreedhar et al. · From the abstract

Names both Atorvastatin and Fish Oil in its title.

Chemopreventive effect of omega-3 polyunsaturated fatty acids and atorvastatin in rats with bladder cancer.

Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine · 2017 · PMID 28218036

Animal study

“However, the combined treatment with both drugs exhibited the major protective effect and nearly corrected the dyslipidemia that has been induced by N-butyl-N-(4-hydroxybutyl)nitrosamine. Collectively, omega-3 polyunsaturated fatty acids and atorvastatin, besides having anti-inflammatory properties, proved a chemopreventive effect against bladder cancer, which nominates them to be used as adjuvant therapy with other chemotherapeutics.”

El-Ashmawy et al. · From the abstract

Names both Atorvastatin and Fish Oil in its title.

Omega-3 fatty acids and atorvastatin suppress ventricular fibrillation inducibility in hypertriglyceridemic rat hearts: implication of intracellular coupling protein, connexin-43.

Journal of physiology and pharmacology : an official journal of the Polish Physiological Society · 2010 · PMID 21224503

Animal study

“Results indicate that antiarrhythmic effects of omega-3 FA and atorvastatin are linked with modulation of expression and/or phosphorylation of Cx43 and protection of cardiomyocyte and cell-to-cell junction integrity. As both compounds are ligands for PPAR, a possible regulation of Cx43 gene expression and pathways involved in Cx43 phosphorylation should be investigated.”

Bacova et al. · From the abstract

Names both Atorvastatin and Fish Oil in its title.

N-3 fatty acid supplementation mediates lipid profile, including small dense LDL, when combined with statins: a randomized double blind placebo controlled trial.

Lipids in health and disease · 2022 · PMID 36050695

Randomized Controlled Trial

“In this group of hyperlipidemic patients on a stable statin prescription, OM3 plus atorvastatin improved small dense LDL concentrations, non-HDL-C, VLDL-C and TG to a greater extent than atorvastatin alone. Further studies are warranted in this area.”

Dogay Us et al. · Authors' conclusion

Names Atorvastatin and Fish Oil 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 Atorvastatin, Fish Oil, 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.
