HelloPharmacist Scorecard of Borage Oil 1,000 mg EFA by Wonder Laboratories

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.

From our pharmacy team — supplement deep dive

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 5 of its 5 active ingredients.
  • “Approximate Fatty Acid Content” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

Borage Oil 1,000 mg EFA contains 5 active ingredients: borage oil itself, plus gamma-linolenic acid (GLA), linoleic acid, oleic acid, and polyunsaturated fat — all essential fatty acids (EFAs) that your body needs. Borage oil is the main active component and supplies the gamma-linolenic acid; oleic acid is a monounsaturated fat also found in olive oil.

The inactive ingredients are gelatin, vegetable glycerin, and mixed tocopherols (a form of vitamin E used as a preservative).

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: Coronary heart disease (CHD) — rated "Possibly Effective" (Oleic Acid) (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Possibly Effective" (Oleic Acid) (Natural Medicines).

Evidence for borage oil in this product is mixed. For atopic dermatitis (eczema), the data rates borage oil as possibly ineffective.

For ADHD, acute respiratory distress syndrome, and alcoholism, we don't have enough reliable evidence to say whether it works or not. The oleic acid in the blend shows possibly effective ratings for high cholesterol and coronary heart disease when you eat foods rich in it (like olive oil), though this product is a concentrated supplement, not a food source.

The evidence, ingredient by ingredient Oleic Acid Borage

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 1 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Borage seed oil is generally well tolerated by most people orally. The most common side effects are belching, bloating, diarrhea, and soft stools.

The main safety worry is pyrrolizidine alkaloids (PAs) — liver-toxic plant compounds found in borage leaf, flower, and some seed, though seed oil itself contains little to none. This product should be avoided in pregnancy because borage carries a theoretical risk to the uterus and possible liver toxicity from alkaloids.

Breastfeeding safety data is also insufficient, so talk with your doctor or pharmacist before using it if you're nursing. Oleic acid from food sources is considered safe, but concentrated supplement doses haven't been well studied in pregnancy or while breastfeeding.

Side effects, ingredient by ingredient Oleic Acid Borage

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?
  • 2 of the 2 matched ingredients can interact with medications — Borage, Oleic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 313 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 (like warfarin or aspirin) — borage oil may raise bleeding risk. Also flag antipsychotic medications (phenothiazines), diabetes medications that lower blood sugar, and any drugs that induce the CYP3A4 liver enzyme.

If you take any of these, confirm it's okay before you start.

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 worth considering if you're interested in omega-6 fatty acids and don't take blood thinners, antipsychotics, or diabetes medications. If you do take any prescription drugs, run them through the checker below first — borage oil has several moderate interactions.

Steer clear if you're pregnant, planning pregnancy, or breastfeeding. Talk to your own doctor or pharmacist before starting it, especially if you have liver concerns or take multiple medications.

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.

Likelihood Possible Evidence D

Oleic Acid1 drug type · 86 drugs

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.

Borage Oil 1,000 mg EFA by Wonder Laboratories: Common Questions

Does Borage Oil 1,000 mg EFA by Wonder Laboratories interact with any medications?
Yes. Based on its ingredients, Borage Oil 1,000 mg EFA has a known interaction with 312 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Borage Oil 1,000 mg EFA 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.
Can I take this if I'm pregnant?
No — borage oil is rated likely unsafe in pregnancy because of concern about liver-toxic alkaloids and a theoretical risk to the uterus. Oleic acid from food is fine, but supplement amounts haven't been studied well in pregnancy either. Talk to your doctor or pharmacist about alternatives if you're pregnant or planning to become pregnant.
What side effects should I expect?
Most people tolerate borage seed oil well, but belching, bloating, diarrhea, and soft stools are common. Borage plant parts like the leaf and flower can be liver-toxic if they contain pyrrolizidine alkaloids, though the seed oil in this product should have little to none — but look for 'PA-free certified' on the label for extra assurance.
Does this actually help with eczema?
The evidence rates borage oil as possibly ineffective for atopic dermatitis (eczema), so we don't have strong data backing it for that use. For ADHD and other conditions listed, we simply don't have enough reliable research to say whether it works.
Is this a blood thinner?
Borage oil itself isn't a blood thinner, but it may increase bleeding risk if you already take blood thinners or antiplatelet drugs like warfarin or aspirin. If you take either, check with your doctor or pharmacist before starting this product.
What is gamma-linolenic acid, and why is it in here?
Gamma-linolenic acid (GLA) is an omega-6 essential fatty acid that borage oil is naturally rich in. It's included because it's one of the key active compounds in borage. However, it's also the constituent that raises bleeding risk when you combine borage with blood thinners.
Can I take this while breastfeeding?
There isn't enough safety data on borage oil or oleic acid to know either way. Talk with your doctor or pharmacist before taking it while breastfeeding — they can help you decide based on your individual situation.
