What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 6 active ingredients.
  • “CLA/Omega 3-6-9 Blend” is a proprietary blend — the label gives one combined amount (2 Gram(s)) without saying how much of each component you get.

Censor contains six ingredients. The active components are a blend of polyunsaturated fats and omega oils—safflower oil, fish oil, flaxseed oil, evening primrose oil, and borage oil.

These are all fatty acid sources meant to deliver omega-3, omega-6, and other lipid compounds. The product also contains inactive ingredients: gelatin (the capsule), glycerin, and vitamin E (d-alpha-tocopherol).

Does it work?

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: support fat loss and healthy body composition.
  • We looked for evidence on: Dyslipidemia, Cardiovascular disease (CVD), Coronary heart disease (CHD), Atherosclerosis, Weight management, Metabolic health — and 1 related terms.
  • The strongest evidence on file: Fish Oil is rated "Possibly Effective" for HIV/AIDS-related dyslipidemia (Natural Medicines).
  • Also on file: Fish Oil is rated "Possibly Ineffective" for Atherosclerosis.
  • Also on file: Safflower is rated "Insufficient Reliable Evidence To Rate" for Coronary heart disease (CHD).

The evidence for these individual ingredients is mixed and often limited. Fish oil shows effectiveness for high triglycerides, and possibly helps with cachexia (severe weight loss), heart failure, and fatty liver disease.

Safflower, flaxseed, evening primrose, and borage oil all show insufficient or possibly ineffective evidence for their marketed uses—including weight management, cholesterol, rheumatoid arthritis, and skin conditions. The data we hold doesn't establish that this combination works for any specific condition.

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 5 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.

Fish oil is generally well tolerated at typical supplement doses, though it can cause abdominal pain, bad breath, fishy aftertaste, heartburn, loose stools, nausea, and rash in some people. At doses of 3 grams or more daily, it may thin the blood and increase bleeding risk.

Safflower oil in food amounts is well tolerated, but concentrated supplements have less safety data; there are rare case reports of liver failure linked to high-dose safflower use. Flaxseed oil is generally well tolerated but may cause loose stools, diarrhea, dry mouth, or upset stomach at high doses.

Evening primrose and borage oils are generally well tolerated short-term, though they can cause abdominal upset, diarrhea, bloating, and belching. Borage oil raises a concern: some borage plant parts contain liver-toxic alkaloids, though borage seed oil certified as alkaloid-free is considered safer.

For pregnancy and breastfeeding, fish oil is often used but requires doctor oversight; safflower is possibly unsafe in pregnancy and should be avoided in medicinal amounts; flaxseed is possibly safe but lacks full data; evening primrose is possibly safe; borage is likely unsafe in pregnancy and lactation.

Each ingredient & the kinds of drugs it affects

For each ingredient in Censor 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.

Fish Oil9 drug types · 327 drugs

Antihypertensive Drugs

Theoretically, taking fish oil with antihypertensive drugs might increase the risk of hypotension.
Clinical evidence indicates that fish oils can modestly lower blood pressure and might have additive effects in patients treated with antihypertensives.

Likelihood Probable Evidence B
Contraceptive Drugs

Theoretically, taking fish oil with contraceptive drugs might decrease the triglyceride-lowering effects of fish oil.
There is some evidence that contraceptive drugs might interfere with the triglyceride lowering effects of fish oils.

Likelihood Probable Evidence B
Cyclosporine (Neoral, Sandimmune)

Taking fish oil with cyclosporine might increase levels and adverse effects of cyclosporine.
In kidney transplant recipients on a general immunosuppressive regimen, taking omega-3 fatty acids daily seems to increase peak blood levels of cyclosporine when compared with placebo. This increase was as much as 20% after one month. However, the area under the curve was not significantly affected.

Likelihood Probable Evidence B
Orlistat (Xenical, Alli)

Theoretically, taking fish oil with orlistat might decrease the absorption of fish oil fatty acids.
Orlistat binds lipase in the gastrointestinal tract and reduces fat absorption. Theoretically, taking fish oil with orlistat might decrease absorption of fish oil fatty acids. To avoid this potential interaction, recommend separating administration of orlistat and fish oil by at least 2 hours.

Likelihood Probable Evidence D
Sirolimus (Rapamune)

Taking fish oil with sirolimus might increase levels and adverse effects of sirolimus.
Pharmacokinetic research shows that omega-3 fatty acids increase exposure to sirolimus in kidney transplant patients on a calcineurin inhibitor-free immunosuppressive regimen. A 25% dose reduction in sirolimus was required to keep patients within the expected trough-concentration window. Researchers hypothesize that this may be due to inhibition of cytochrome P450 3A4 (CYP3A4) by fish oil, although this has not been confirmed in clinical research.

Likelihood Probable Evidence B
Tacrolimus (Prograf)

Taking fish oil with tacrolimus might increase levels and adverse effects of tacrolimus.
In a small group of patients, taking fish oil 2.6 grams (Omacor) daily for 4 weeks increased the 8-hour area under the curve of tacrolimus by 25% when compared with baseline. Peak levels were increased by approximately 22%. Researchers hypothesize that this may be due either to an increase in bioavailability or to inhibition of cytochrome P450 3A4 (CYP3A4) by fish oil, although this has not been confirmed in clinical research.

Likelihood Probable Evidence B
Anticoagulant/Antiplatelet Drugs

Fish oil may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, evidence is conflicting.
While fish oil may not be a potent inhibitor of platelet function, high doses of fish oil might have antiplatelet effects. Theoretically, concomitant use of fish oil with anticoagulant or antiplatelet drugs may increase the risk of bleeding. However, the most rigorous research shows that short-term doses of fish oil 10 grams daily or long-term doses of 1.5 grams daily for up to 52 weeks does not increase the risk of bleeding or affect coagulation parameters in chronically ill and vulnerable patients. Other controlled research shows that fish oil does not affect platelet function or increase the risk of bleeding. Some research even suggests that perioperative fish oil use decreases bleeding risk. Some research suggests fish oil does not have additive antiplatelet effects when combined with aspirin, but other clinical evidence suggests that adding fish oil to low-dose aspirin treatment increases antiplatelet effects in patients who are aspirin-resistant. Also, some clinical research seems to show that fish oil has additive antiplatelet effects when used with aspirin and clopidogrel compared to aspirin and clopidogrel alone.

Likelihood Unlikely Evidence B
Platinum Agents

Theoretically, taking fish oil with platinum agents can cause resistance to platinum agents, potentially decreasing their effectiveness.
Platinum-induced fatty acids (PIFAs) are fatty acids secreted from human and mouse stem cells when exposed to platinum-based chemotherapy. Animal research suggests that PIFAs cause resistance to chemotherapy by stimulating lysophospholipid production in the spleen, which interferes with the DNA damage caused by certain chemotherapy drugs. One PIFA, known as 16:4(n-3), has been found in both raw fish and some commercially available fish oil products. Mackerel and herring have high PIFA concentrations, while salmon and tuna have low PIFA concentrations. Levels of PIFA in commercial fish oil products ranged from 0.2- 5.7 microMol. Animal research shows that PIFA-containing fish oil products cause resistance to cisplatin, fluorouracil, irinotecan, and oxaliplatin. It is unclear if all commercially available fish oil products contain PIFAs. Additionally, it is argued that levels of PIFA found in some fish oil products are too low to be of clinical concern. Furthermore, a lack of chemotherapy resistance in countries with high fish intake, such as Greenland, Japan, and Norway, suggest that this interaction may not be clinically significant.

Likelihood Unlikely Evidence D
Warfarin (Coumadin)

Fish oil may have antiplatelet effects and might increase the risk of bleeding if used with warfarin.
Fish oil has antiplatelet effects at high doses. Case reports show elevated INR in patients taking warfarin and fish oil 1-2 grams daily. However, some clinical research shows that taking fish oil 3-6 grams daily does not significantly increase INR in patients taking warfarin.

Likelihood Unlikely Evidence B
Fish Oil full monograph & interactions

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
Flaxseed oil full monograph & interactions

Evening primrose 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
Evening primrose oil full monograph & interactions

Borage oil3 drug types · 226 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, borage seed oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In healthy individuals, borage seed oil supplementation does not seem to affect platelet aggregation. However, gamma-linolenic acid, a constituent of borage seed oil, seems to decrease platelet aggregation by 45% and increase the risk of bleeding by 40% in animal and clinical research.

Likelihood Possible Evidence B
Cytochrome P450 3A4 (Cyp3A4) Inducers

Theoretically, taking borage with drugs that induce CYP3A4 might increase levels of pyrrolizidine alkaloid (PA) toxic metabolites.
Although borage seed oil contains little to no PAs, some borage plant parts, such as the leaf, flower, and seed, can contain hepatotoxic PAs. Hepatotoxic PAs are substrates of CYP3A4, which converts these chemicals into toxic metabolites. Tell patients to avoid borage preparations that are not certified and labeled as hepatotoxic PA-free.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, taking borage sed oil with phenothiazines might increase the risk of seizures.
Borage seed oil contains gamma-linolenic acid (GLA). There is concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines. This is based on limited data from two reports published in the 1980s. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with evening primrose, another source of GLA. However, none experienced an actual seizure. In the other report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily was added. One of these patients had a prior history of seizures. It is unclear whether evening primrose had any additive epileptogenic effects with the phenothiazines, but there is no evidence that taking GLA-containing supplements alone can cause seizures.

Borage oil full monograph & interactions

Safflower oil3 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

High doses of safflower oil might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Small clinical studies show that taking safflower oil, approximately 55 grams daily for 2-3 weeks, decreases platelet aggregation. However, taking lower doses of safflower oil, such as 5 grams daily for 4 weeks, does not seem to affect platelet function. In one case report, a 74-year-old male stabilized on warfarin developed urinary tract bleeding and an elevated INR after taking a safflower extract 20 grams daily for 14 days.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, safflower oil might alter the effects of antidiabetes drugs.
Some clinical research shows that taking safflower oil 10 grams daily for 3 weeks can increase fasting blood glucose in patients with type 2 diabetes. However, clinical research in patients with metabolic syndrome with or without impaired glucose tolerance shows that taking safflower oil 8 grams daily for 12 weeks reduces fasting glucose levels by around 8 mg/dL. Some clinical research also shows that taking safflower oil 8 grams daily for 16 weeks does not affect fasting glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence B
Warfarin

Theoretically, safflower oil might increase the risk of bleeding when taken with warfarin.
In one case report, a 74-year-old male stabilized on warfarin developed urinary tract bleeding and an elevated INR after taking a safflower extract 20 grams daily for 14 days.

Censor by NDS Nutrition Products: Common Questions

Does Censor by NDS Nutrition Products interact with any medications?
Yes. Based on its ingredients, Censor has a known interaction with 574 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Censor 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.
Does Censor help with weight loss or managing triglycerides?
Fish oil in this product has evidence supporting its use for high triglycerides. For the other oils (safflower, flaxseed, evening primrose, borage), the evidence shows they're possibly ineffective or insufficient for weight loss and cholesterol—so Censor as a combination isn't established to work for those purposes.
Can I take Censor if I'm on warfarin or another blood thinner?
No—not without talking to your doctor or pharmacist first. Safflower oil, fish oil, flaxseed oil, evening primrose oil, and borage oil all have documented interactions with blood thinners and can increase bleeding risk. Your medications and dose may need adjustment.
What are the most common side effects?
Fish oil commonly causes abdominal pain, bad breath, fishy aftertaste, heartburn, loose stools, and nausea. Borage, flaxseed, and evening primrose oils can cause bloating, diarrhea, and abdominal upset. These effects happen in a small number of people at typical doses.
Is Censor safe to use during pregnancy?
The safety data varies by ingredient. Fish oil is often used in pregnancy but requires doctor guidance. Safflower should be avoided in medicinal amounts during pregnancy. Flaxseed is possibly safe, evening primrose is possibly safe, and borage is likely unsafe. Talk with your doctor before starting.
What does borage oil do, and should I worry about liver damage?
Borage oil is included for its gamma-linolenic acid content, an omega-6 fatty acid. Borage seed oil certified as free of hepatotoxic alkaloids is generally well tolerated. However, some borage plant parts can contain liver-toxic compounds, so quality and certification matter. Choose a product that specifies alkaloid-free borage seed oil.
Can I take this with blood pressure medication?
Fish oil and flaxseed oil can both lower blood pressure, so combining them with antihypertensive drugs theoretically increases the risk of blood pressure dropping too far. Check with your pharmacist—your blood pressure or medication dose may need monitoring.
