What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 6 of its 6 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Nature's Way Organic Flax Oil is a liquid supplement containing 6 ingredients. The active components are flaxseed oil, omega-3 fatty acids (primarily DHA), omega-6 fatty acids, polyunsaturated fat, and monounsaturated fat—all healthy fats derived from flax and seed sources.

The product also contains inactive ingredients (sunflower seed oil, rosemary leaf extract, mixed tocopherols, ascorbic acid, and citric acid) that serve as carriers, preservatives, and stabilizers.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Hyperlipidemia — rated "Possibly Effective" (Docosahexaenoic Acid (dha)) (Natural Medicines).
  • On file: Preterm labor — rated "Possibly Effective" (Docosahexaenoic Acid (dha)) (Natural Medicines).

The evidence for flaxseed oil is mixed. It's rated possibly ineffective for obesity, rheumatoid arthritis (RA), bipolar disorder, and high cholesterol (hyperlipidemia).

The omega-3 fatty acids (DHA) in this product show more promise: they're rated possibly effective for preventing preterm labor and possibly effective for high cholesterol, but possibly ineffective for cognitive function and ADHD. Overall, the research doesn't strongly support this product for most common health goals—talk with your doctor about whether it fits your needs.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Flaxseed oil is generally well tolerated when taken by mouth. A small number of people report mild side effects like changes in bowel habits, dry mouth, or indigestion at typical doses of about 5 grams daily.

High doses (30 grams or more per day) are more likely to cause loose stools or diarrhea. Severe allergic reactions are rare but possible.

DHA is also generally well tolerated at supplement doses up to 3 grams daily; the most common side effects are belching, fishy aftertaste, loose stools, and nausea. Quality and dose vary by product, and the safety data for this oil is limited, so check with your doctor before starting.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 3 matched ingredients can interact with medications — Docosahexaenoic Acid (dha), Flaxseed Oil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 379 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check your medications before taking this product if you're on any of the following. Blood thinners or antiplatelet drugs (like warfarin or aspirin)—flaxseed oil and DHA may increase bleeding risk.

Blood pressure medications—both ingredients may lower your blood pressure further. Diabetes medications—DHA may raise blood sugar.

The cholesterol drug ezetimibe (Zetia)—it blocks flaxseed oil's absorption. No interactions are documented for the ingredients we could not check.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product is a source of plant-based omega fatty acids, but the research doesn't strongly support it for weight loss, joint health, mood, or cholesterol. It matters most if you take blood thinners, blood pressure medication, or diabetes medication—those all need a conversation with your doctor or pharmacist first.

If you have no medication interactions and want to try it, it's generally well tolerated, though some people notice mild digestive changes. Talk with your own healthcare provider about whether it's right for you.

Omega-3 Fatty Acids3 drug types · 375 drugs

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.

Likelihood Unlikely Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Probable Evidence B

Flaxseed Oil3 drug types · 293 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, using flaxseed oil in combination with anticoagulant or antiplatelet drugs might have additive effects and increase the risk of bleeding.
Small clinical studies show that consuming flaxseed oil might decrease platelet aggregation and increase bleeding time.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, combining flaxseed oil with other antihypertensive drugs might have additive effects and increase the risk of hypotension.
Some clinical evidence suggests that long-term consumption of flaxseed oil can modestly lower systolic and diastolic blood pressure, while other clinical research shows no effect.

Likelihood Possible Evidence D
Ezetimibe (Zetia)

Concomitant use of flaxseed oil and ezetimibe reduces the absorption of alpha-linolenic acid from flaxseed oil.
In one clinical study, concomitant consumption of ezetimibe 10 mg daily with flaxseed oil 2 grams providing 1 gram of alpha-linolenic acid daily blocked the absorption of alpha-linolenic acid, resulting in an overall reduction in alpha-linolenic plasma levels from baseline.

Organic Flax Oil by Nature's Way: Common Questions

Does Organic Flax Oil by Nature's Way interact with any medications?
Yes. Based on its ingredients, Organic Flax Oil has a known interaction with 379 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Flax Oil contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe to take while I'm pregnant?
Flaxseed oil is rated possibly safe in pregnancy, but the safety data isn't complete. DHA is rated likely safe and is often recommended prenatally. Talk with your doctor about whether this product and its dose are right for you and to confirm you're taking a purified, low-mercury source.
Can I take this if I'm breastfeeding?
DHA passes into breast milk and is generally considered acceptable with medical guidance on dose and source. Safety data for flaxseed oil during breastfeeding is limited, and one rating for omega-6 fatty acids indicates possibly unsafe. Check with your doctor about the safety of this specific product while nursing.
Will this help with high cholesterol?
Flaxseed oil is rated possibly ineffective for high cholesterol, while DHA is rated possibly effective. The evidence is mixed, so this product alone may not be enough—talk with your doctor about your cholesterol goals and whether it fits your plan.
What side effects might I notice?
Most people tolerate it well. A small number report mild digestive changes—loose stools, dry mouth, or indigestion—especially at higher doses. The fishy aftertaste and belching are common with fish oil products. Severe allergic reactions are rare.
Can I take this with my blood pressure medication?
Both flaxseed oil and DHA may lower blood pressure on their own, so combining either with blood pressure medication could increase dizziness or fainting risk. Talk with your doctor or pharmacist before starting this product.
What happens if I take this with a blood thinner like warfarin?
Flaxseed oil and DHA may both increase bleeding risk when used with blood thinners or antiplatelet drugs. Confirm with your doctor or pharmacist before taking this product alongside any blood thinner.
