HelloPharmacist Scorecard of Omega Twin by Barlean's
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
Barlean's Omega Twin is a 4-ingredient capsule built around omega-3 and omega-6 fatty acids. The omega-3 content comes from docosahexaenoic acid (DHA), one of the long-chain fats your brain and eyes use.
The other named active is Gamma-Linolenic Acid, an omega-6 fat. The product also contains Polyunsaturated Fat and Monounsaturated Fat, which are additional sources of these essential fats.
Each capsule is housed in a light-resistant gelatin shell.
Does it work?
Moderate evidence
For omega-3 (DHA), the evidence suggests it may be effective for preterm labor prevention and high cholesterol (hyperlipidemia), though the evidence is not conclusive. DHA does not appear to help with cognitive function or ADHD based on the data we have.
Omega-6 fatty acids in this product show possibly ineffective ratings for high cholesterol, cardiovascular disease, multiple sclerosis, and child development — meaning the evidence does not support their use for these purposes. The overall evidence base for omega-6 supplement benefits remains uncertain.
How safe is it?
Well-documented data
DHA is generally well tolerated at typical supplement doses. The most common side effects are belching, a fishy aftertaste, loose stools, and nausea.
Rare serious effects include a potential increased bleeding risk at high doses. A small number of people have reported rash, acne, or hair loss in studies, though it's unclear whether DHA was the cause.
The safety data advises that DHA is likely safe in pregnancy and lactation, though you should use only a purified, low-mercury source and check with your doctor on dose. Omega-6 supplements present a more uncertain safety picture — while omega-6 from food is fine, the safety of concentrated supplements is not well established, and the data rates it possibly unsafe in some pregnancy contexts.
Meds to double-check
Moderate interaction found
Before taking Omega Twin, double-check with your doctor or pharmacist if you take blood thinners (anticoagulants or antiplatelet drugs) — DHA may increase bleeding risk. Also flag any blood pressure medications or diabetes drugs, since DHA may lower blood pressure further or raise your blood sugar levels on medication.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Omega Twin is built on two essential fatty acids that your body needs, and DHA has some evidence for helping prevent early labor and managing cholesterol. However, if you take blood thinners, blood pressure medications, or diabetes drugs, you'll need to check with your doctor or pharmacist before starting, since DHA may interact with all three.
The omega-6 side of the product shows little benefit for most conditions and carries uncertain safety as a concentrated supplement.

Omega Twin by Barlean's Drug Interactions
HelloPharmacist Interaction Report
Barlean's Omega Twin contains omega-3 fatty acids (DHA) and omega-6 fatty acids, and DHA has documented interactions with several medication types.
The most serious concern is with blood thinners (anticoagulant or antiplatelet drugs) — DHA may theoretically increase bleeding risk, a Moderate severity interaction. You'll also want to watch for interactions with blood pressure medications and diabetes drugs.
Read the full breakdown — every affected drug type, severity by severity
DHA can add to the blood-pressure-lowering effect of antihypertensive medications, potentially causing your blood pressure to drop too low. Similarly, if you take diabetes medications, DHA may theoretically reduce how well they work by raising your fasting blood sugar levels.
Both of these are rated Moderate severity.
Omega-6 fatty acids in this product were checked and no interactions are documented in our data. We could not check Gamma-Linolenic Acid or Omega-9 Fatty Acids, as we hold no interaction data for them.
Altogether, these interactions span 375 individual medications. Before you start Omega Twin, use the search tool below to check your exact medications.

Omega-3 Fatty Acids
Anticoagulant/Antiplatelet Drugs
Theoretically, DHA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Although some clinical evidence suggests that DHA might reduce collagen-stimulated platelet aggregation and thromboxane release, most clinical evidence suggests that DHA alone does not affect blood clotting. However, theoretically, when given in combination with EPA as fish oil, concomitant use with anticoagulant or antiplatelet drugs (including aspirin) might increase risk of bleeding.
Antidiabetes Drugs
Theoretically, taking DHA with antidiabetes drugs might reduce the effects of these medications.
In people with type 2 diabetes, including those taking oral hypoglycemic medications, DHA seems to increase fasting blood glucose levels.
Antihypertensive Drugs
Theoretically, taking DHA with antihypertensive drugs might increase the risk of hypotension.
Fish oils containing DHA can lower blood pressure and might have additive effects in patients treated with antihypertensives; use with caution.
