HelloPharmacist Scorecard of OmegaFactors Borage Oil by Natural Factors
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
OmegaFactors Borage Oil contains 4 active ingredients: gamma-linolenic acid and linoleic acid (fatty acids from the borage seed oil itself), oleic acid (a monounsaturated fat also found in olive oil), and borage oil as the primary botanical. These are combined with inactive ingredients including the softgel capsule shell and mixed tocopherols (a form of vitamin E used as a preservative).
Does it work?
Not established
The evidence on this product's effectiveness is mixed. Oleic acid is possibly effective for high cholesterol and heart disease prevention.
Borage oil is possibly ineffective for eczema (atopic dermatitis) based on available data. For other uses — including ADHD, acute respiratory distress syndrome, and alcoholism — the evidence we hold is insufficient to rate whether it works.
Talk with your doctor about whether this product fits your health goals.
How safe is it?
Well-documented data
Borage seed oil is generally well tolerated when taken by mouth; the most common mild side effects are belching, bloating, diarrhea, and soft stools. Oleic acid from food sources is considered safe, though concentrated supplements haven't been well studied.
The borage plant does contain liver-toxic alkaloids (pyrrolizidine alkaloids) in its leaf, flower, and seed, though seed oil itself contains little to none. If your product is certified alkaloid-free, that's a better choice.
The safety data advises against borage oil in pregnancy due to possible liver-toxic alkaloids and theoretical risk to the uterus; data on breastfeeding is insufficient — talk with your doctor or pharmacist if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (Moderate interaction risk); diabetes medications like metformin or sulfonylureas (Moderate risk); antipsychotics, especially phenothiazines (Moderate risk); or drugs that induce the CYP3A4 liver enzyme, such as rifampin or St. John's Wort (Moderate risk).
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 help with cholesterol and heart health through its oleic acid content, though the evidence is still preliminary. If you take blood thinners, diabetes medications, antipsychotics, or seizure drugs, you'll want to check with your doctor or pharmacist before starting — borage oil can interact with those medication types.

OmegaFactors Borage Oil by Natural Factors Drug Interactions
HelloPharmacist Interaction Report
OmegaFactors Borage Oil from Natural Factors has documented interactions through its borage oil and oleic acid content.
The most serious concern is a Moderate-severity risk with blood thinners (anticoagulant/antiplatelet drugs): borage oil may increase bleeding risk, since one of its components can reduce how quickly your blood clots by up to 45%.
Read the full breakdown — every affected drug type, severity by severity
Borage oil also carries Moderate-severity interactions with antipsychotics called phenothiazines — there's a theoretical risk it could lower your seizure threshold — and with drugs that speed up a liver enzyme called CYP3A4, which might raise levels of toxic compounds if you're taking borage leaf, flower, or seed (though the seed oil itself contains little of these toxins). Oleic acid, another ingredient here, may theoretically increase the effects of diabetes medications that lower blood sugar.
We couldn't check gamma-linolenic acid and linoleic acid — we hold no interaction data for those. Before you start this product, check your exact medications using the search tool on this page, and talk it over with your doctor or pharmacist, especially if you take blood thinners, diabetes drugs, seizure medications, or antipsychotics.

For each ingredient in OmegaFactors Borage Oil 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.
Borage Oil
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.
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.
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.
Oleic Acid
Antidiabetes Drugs
Theoretically, oleic acid might increase the effects of antidiabetes drugs. Preliminary clinical research in patients with type 2 diabetes taking oral hypoglycemic drugs shows that eating a diet rich in oleic acid from olive oil decreases fasting blood glucose levels when compared to eating a diet rich in linoleic acid from sunflower oil. It is unknown if taking oleic acid supplements would have this effect or if this change is clinically significant. Until more is known, use caution. Dose adjustment may be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.
