3/5 Evidence Score

B-Romega is a branded herring roe (caviar) oil developed by Groupe Berkem with the Norwegian marine specialist Arctic Bioscience. Unlike standard fish oil, where omega-3s are carried as triglycerides or ethyl esters, much of the EPA and DHA in herring roe oil is bound to phospholipids, the same form found in cell membranes, which may aid absorption. The oil is upcycled from wild-caught, MSC-certified herring and naturally contains precursors of specialized pro-resolving mediators. It is positioned for heart, brain, eye, and skin health across the lifespan.

Studied Dose Herring roe (caviar) oil has been studied in human trials at doses providing a few hundred milligrams of combined EPA and DHA per day, mostly in phospholipid form.
Active Compound Herring roe (caviar) oil providing omega-3 fatty acids (EPA and DHA) largely bound to phospholipids, plus naturally occurring precursors of specialized pro-resolving mediators (SPMs).

Benefits

Heart Health

The EPA and DHA in herring roe oil support cardiovascular health, including healthy triglyceride and lipid levels, a well-established benefit of marine omega-3s.

Well-Absorbed Omega-3 Status

Because much of its EPA and DHA is bound to phospholipids rather than triglycerides, herring roe oil delivers omega-3s in a form that is efficiently taken up and incorporated into cell membranes.

Anti-Inflammatory and Resolution Support

Herring roe oil naturally contains precursors of specialized pro-resolving mediators, signaling molecules that help the body switch off inflammation once it is no longer needed.

Brain and Cognitive Support

DHA is a major structural fat in the brain. Supplying it in phospholipid form supports normal brain function and cognition across life stages.

Eye and Skin Health

DHA is concentrated in the retina, and omega-3s support tear-film and skin-barrier quality, underpinning the eye- and skin-health positioning of B-Romega.

Mechanism of action

1

Phospholipid-Bound Omega-3 Delivery

EPA and DHA carried on phospholipids integrate readily into cell membranes, which may improve incorporation compared with some triglyceride or ethyl-ester fish oils.

2

Specialized Pro-Resolving Mediators

Herring roe oil supplies precursors the body converts into resolvins and related mediators that actively resolve inflammation rather than simply blocking it.

3

Membrane and Triglyceride Effects

Marine omega-3s lower circulating triglycerides and improve membrane fluidity and receptor signaling in heart, brain, and vascular tissue.

4

Retinal and Neural DHA Supply

DHA is selectively enriched in photoreceptors and synaptic membranes; dietary supply supports visual and neural membrane function.

Clinical trials

1
Omega-3 Bioavailability From Herring Roe Oil (RCT)

Randomized human bioavailability study of phospholipid-rich herring roe oil.

Men and women with mildly elevated triglycerides.

EPA and DHA from herring roe oil were bioavailable and raised omega-3 status, confirming absorption of the phospholipid form.

2
Herring Roe Phospholipids, Blood Lipids and Glucose (Clinical Trial)

Clinical trial of herring roe phospholipids in healthy young adults.

Healthy young adults.

Supplementation improved plasma lipids and glucose tolerance compared with baseline, supporting cardiometabolic benefits.

3
Herring Roe Oil and Skin (Psoriasis RCT)

Randomized, double-blind, placebo-controlled trial of herring roe oil in people with psoriasis.

Adults with psoriasis.

Herring roe oil improved skin outcomes versus placebo, reported here as structure/function support for skin health rather than a treatment claim.

Side effects and drug interactions

Common Potential side effects

Fishy aftertaste or burps (mild, common with marine oils).
Mild digestive upset such as nausea or loose stools.
Caution in people with fish or shellfish allergy.
Theoretical additive bleeding risk at high doses.
Quality and oxidation vary by product; choose a fresh, tested oil.

Important Drug interactions

ANTICOAGULANTS / ANTIPLATELETS - high-dose omega-3 may add a mild blood-thinning effect with warfarin, clopidogrel, or aspirin.
ANTIHYPERTENSIVES - omega-3s can have a small additive blood-pressure-lowering effect.
FISH / SHELLFISH ALLERGY - herring roe oil is a marine product and may not be suitable.
Discuss high-dose use with a clinician before surgery.
