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 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 5 active ingredients: canola oil, evening primrose seed oil, organic flaxseed oil, black currant seed oil, and pumpkin seed oil — a blend of plant-based oils rich in omega-3, omega-6, and omega-9 fatty acids. Each softgel also contains inactive ingredients: gelatin (capsule), glycerin, purified water, and caramel for color.

Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Anti-aging support.
  • We looked for evidence on: Skin health, Joint health, Cardiovascular aging.
  • The closest evidence on file: Flaxseed Oil is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD) (Natural Medicines).

The evidence for these oils varies. Canola oil is possibly effective for heart disease but possibly ineffective for weight loss; there's insufficient evidence to rate it for familial high cholesterol.

Evening primrose oil is possibly ineffective for asthma and likely ineffective for breast pain (mastalgia), with insufficient evidence for ADHD, acne, and other uses. Flaxseed oil is possibly ineffective for weight loss, rheumatoid arthritis, bipolar disorder, and high cholesterol.

Black currant seed oil has insufficient evidence to rate for Alzheimer disease, liver disease, respiratory infections, cough, and eczema. Pumpkin seed oil is possibly effective for benign prostate enlargement but has insufficient evidence for hair loss, bladder issues, parasites, and urinary tract infections.

Overall, the evidence for this blend's specific health claims isn't well established in our data.

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 4 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Evening primrose oil is generally well tolerated short-term but long-term safety data are limited; the most common side effects are abdominal pain, diarrhea, indigestion, gas, nausea, and vomiting. Rare reports include dizziness, headache, skin rash, and acne.

Flaxseed oil is generally well tolerated; a small number of patients (about 3%) reported changes in bowel habits, dry mouth, or indigestion at typical doses, and high doses (30+ grams daily) can cause loose stools or diarrhea. Black currant seed oil caused only mild diarrhea in 8 out of 2,154 patients in one study.

Pumpkin seed oil is generally well tolerated but may cause abdominal discomfort, diarrhea, nausea, or vomiting; rare severe reactions include anaphylaxis. Evening primrose oil should be avoided during pregnancy unless your doctor directs otherwise; it's possibly safe during pregnancy and lactation but safety data are limited.

Flaxseed oil and pumpkin seed oil are possibly safe in pregnancy with limited data; flaxseed oil safety during breastfeeding isn't well studied. Black currant seed oil has no pregnancy or lactation data on file.

Canola oil is likely safe in pregnancy and safe in normal food amounts during breastfeeding, though concentrated supplement doses aren't well studied.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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

Why this rating?
  • 4 of the 5 matched ingredients can interact with medications — Pumpkin, Flaxseed Oil, Evening Primrose, Black Currant.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 389 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.

Before taking this product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (such as warfarin, clopidogrel, or aspirin) — evening primrose oil, flaxseed oil, and black currant seed oil all carry Moderate risk of increased bleeding. Also check if you take lithium, phenothiazines (antipsychotics), antihypertensive (blood pressure) medications, ezetimibe (Zetia), or any CYP2C9 substrate drugs.

No interactions are documented in our data for canola oil alone among these ingredients.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you're interested in omega-3, omega-6, and omega-9 fatty acids from plant sources, but it's essential to check all five ingredients — especially evening primrose oil, flaxseed oil, and black currant seed oil — against your current medications before starting. If you take blood thinners, antipsychotics, lithium, or cholesterol medications, talk with your own doctor or pharmacist first, because the interactions can be significant.

Long-term safety data for these oils as concentrated supplements are limited, so personalized medical advice is especially important.

For each ingredient in Omega 3-6-9 with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

organic 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.

Likelihood Probable Evidence B

Evening Primrose seed Oil5 drug types · 233 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, evening primrose oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Evening primrose oil contains gamma linolenic acid (GLA). There is preliminary clinical evidence that GLA can reduce platelet aggregation and prolong bleeding time.

Likelihood Possible Evidence D
Lithium

Theoretically, concomitant use of lithium with evening primrose oil might decrease lithium levels and effects.
In a case report, a patient on a stable dose of lithium for 10 years experienced a reduction in lithium levels after taking evening primrose oil 500 mg daily. Baseline levels were 0.69 mmol/L, which decreased to 0.37 mmol/L after 2 months and 0.23 mmol/L after 3 months of use. Lithium levels increased within 6 weeks of discontinuing evening primrose oil, to 0.73 mmol/L; no clinical effects were noted.

Likelihood Possible Evidence D
Lopinavir/Ritonavir (Kaletra)

Theoretically, evening primrose oil might increase the levels and effects of lopinavir.
In a case report, an HIV patient who took evening primrose oil (Efamol) along with lopinavir/ritonavir experienced an increase in serum levels of lopinavir to 15.2 mg/L. Six weeks after discontinuing evening primrose oil, levels of lopinavir returned to the normal range of 5-10 mg/L. When re-challenged with evening primrose oil for a week, the patient's lopinavir levels increased from 6.69 to 8.11 mg/L. It is suspected that evening primrose oil increases levels of lopinavir by inhibiting cytochrome P450 3A4 (CYP3A4), which metabolizes lopinavir. However, this effect has not been reported in other research.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, taking evening primrose oil with phenothiazines might increase the risk of convulsions.
Evening primrose oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure. In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose oil 4 grams daily was added. One of these patients had a prior history of seizures. It is unclear whether evening primrose oil had any additive epileptogenic effects with the phenothiazines; there is no evidence that taking evening primrose oil alone causes seizures.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, evening primrose may increase the levels and clinical effects of CYP2C9 substrates.
In vitro research shows that linoleic acid, a constituent of evening primrose oil, inhibits CYP2C9.

Likelihood Possible Evidence D

Black Currant seed Oil2 drug types · 140 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.
Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet effects.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, black currant seed oil might increase the risk of seizure in patients receiving phenothiazines.
Black currant seed oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines, although there is no evidence that black currant seed oil causes seizures. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure. In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily, which contains GLA, was added. One of these patients had a prior history of seizures.

Likelihood Possible Evidence D

Pumpkin seed Oil1 drug type · 1 drug

Lithium

Pumpkin might reduce excretion and increase levels of lithium.
Pumpkin is thought to have diuretic properties. Theoretically, this might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Omega 3-6-9 by Indiana Botanic Gardens: Common Questions

Does Omega 3-6-9 by Indiana Botanic Gardens interact with any medications?
Yes. Based on its ingredients, Omega 3-6-9 has a known interaction with 389 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Omega 3-6-9 contains 5 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 if I'm pregnant or breastfeeding?
The safety data vary by ingredient. Canola oil is likely safe in pregnancy and safe in normal food amounts during breastfeeding. Evening primrose oil, flaxseed oil, and pumpkin seed oil are only possibly safe in both pregnancy and lactation, with limited data. Black currant seed oil has no safety information on file for pregnancy or lactation. Because concentrated supplement doses aren't well studied and there's uncertainty, talk with your doctor or pharmacist before starting if you're pregnant or nursing.
Can this help with heart health or cholesterol?
Canola oil in this product is possibly effective for coronary heart disease but possibly ineffective for weight loss. The other oils have insufficient evidence or are possibly ineffective for cholesterol and related concerns, so the evidence for this blend improving heart health or cholesterol specifically isn't well established in our data.
What are the most common side effects?
Evening primrose oil most commonly causes abdominal pain, diarrhea, indigestion, gas, nausea, and vomiting. Flaxseed oil may cause changes in bowel habits, dry mouth, or indigestion in a small number of users. Black currant seed oil caused only mild diarrhea in a small number of patients in one study. Pumpkin seed oil may cause abdominal discomfort, diarrhea, nausea, or vomiting. Overall, digestive upset is the most frequent reported side effect.
Is there anything in this product that won't interact with medications?
Canola oil showed no documented interactions in our data. However, the other four ingredients — evening primrose oil, flaxseed oil, black currant seed oil, and pumpkin seed oil — do carry documented interactions with various medications, so you'll want to check those against your specific prescriptions.
What is pumpkin seed oil supposed to do in this blend?
Pumpkin seed oil is possibly effective for benign prostate enlargement. The data are insufficient to rate it for hair loss, bladder issues, parasites, and urinary tract infections, so its role in this multi-ingredient blend for general wellness isn't clearly established.
Should I worry about long-term safety?
Quality evidence and long-term safety data for these concentrated supplements are limited. Evening primrose oil is generally well tolerated short-term but long-term effects are unclear. Flaxseed oil, black currant seed oil, and pumpkin seed oil are generally well tolerated, but extended safety isn't well studied. If you plan to take this regularly, discussing long-term use with your doctor or pharmacist is a good idea.
