Black Seed Oil and Fish Oil: what the published research says

PubMed indexes 6 records that name Black Seed Oil 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 Black Seed Oil 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

6 studies naming Black Seed Oil and Fish Oil.

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

RETRACTED: Shen et al. Cold-Pressed Nigella Sativa Oil Standardized to 3% Thymoquinone Potentiates Omega-3 Protection against Obesity-Induced Oxidative Stress, Inflammation, and Markers of Insulin Resistance Accompanied with Conversion of White to Beige Fat in Mice. Antioxidants 2020, 9, 489.

Antioxidants (Basel, Switzerland) · 2025 · PMID 40539260

Retraction Notice

“The journal retracts the article "Cold Press Nigella Sativa oil standardized to 3%, thymoquinone Potentiates Omega-3 Protection against Obesity-Induced Oxidative Stress, Inflammation and Insulin Resistance via Conversion of White to Beige Fat in Mice" [...].”

Shen et al. · From the abstract

Names both Black Seed Oil and Fish Oil in its title.

Dietary Black Seed Effects on Growth Performance, Proximate Composition, Antioxidant and Histo-Biochemical Parameters of a Culturable Fish, Rohu (Labeo rohita).

Animals : an open access journal from MDPI · 2020 · PMID 33383700

“The present study showed that tested black seed levels are safe for rohu. Black seed is cheaply available in local markets of Pakistan; therefore, based on the results of the present study, it is suggested that black seed has potential to be used as natural growth promoter and antioxidant in the diet of rohu.”

Latif et al. · From the abstract

Names both Black Seed Oil and Fish Oil in its title.

Hepatic Regeneration and Reno-Protection by Fish oil, Nigella sativa Oil and Combined Fish Oil/Nigella sativa Volatiles in CCl(4) Treated Rats.

Journal of oleo science · 2018 · PMID 29459508

Animal study

“Conclusion; Oral administration of oil emulsions of native fish oil, Nigella sative crude oil and combined fish oil/Nigella sative volatile oil reduced liver and kidney injury in rat model of CCl4 through exerting anti-inflammatory and antioxidant activity. Fish oil/Nigella sative volatile oil emulsion was the most promising hepato-regenerative and reno-protective formula among the different groups.”

Al-Okbi et al. · From the abstract

Names both Black Seed Oil and Fish Oil in its title.

Comparing Nigella sativa Oil and Fish Oil in Treatment of Vitiligo.

Iranian Red Crescent medical journal · 2014 · PMID 25068060

“Nigella sativa oil and fish oil were effective in reduction the size of patient's lesions; however, Nigella sativa was more effective in comparison to the fish oil. Therefore, using Nigella sativa with the major drugs in the treatment of vitiligo is recommended.”

Ghorbanibirgani et al. · Authors' conclusion

Names both Black Seed Oil and Fish Oil in its title.

Lindane-induced biochemical perturbations in rat serum and attenuation by omega-3 and Nigella sativa seed oil.

Indian journal of biochemistry & biophysics · 2011 · PMID 21793310

Animal study

“Co-administration of omega3 and N.O reversed the hazardous effects induced by gamma-HCH on the liver and kidney and also protected acetylcholinesterase from the inhibitory action of gamma-HCH as well as suppressed the lipid peroxidation. Thus, the results show that omega3 and N.O might prevent oxidative stress and attenuate the changes in the biochemical parameters induced by gamma-HCH in male rats.”

Attia et al. · From the abstract

Names both Black Seed Oil 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:

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 Black Seed Oil, 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.
