HelloPharmacist Scorecard of Borage Super GLA 300 by Planetary Herbals

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
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 4 of its 4 active ingredients.
  • “Borage seed Oil” is listed as a grouped ingredient — the label gives one combined amount (1.30 Gram(s)) without saying how much of each component you get.

Borage Super GLA 300 has four active ingredients, all fatty acids derived from borage seed oil. Gamma-linolenic acid and linoleic acid are omega-6 polyunsaturated fats; oleic acid is a monounsaturated fat; and palmitic acid is a saturated fat.

The softgel also contains gelatin, glycerin, and purified water as inactive ingredients to hold everything together.

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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Rich source of Gamma-Linolenic Acid.
  • We looked for evidence on: Atopic dermatitis (eczema), Rheumatoid arthritis (RA), Neurodermatitis, Skin inflammation, Joint inflammation.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Oleic acid, the one ingredient we have effectiveness data for, is rated possibly effective for high cholesterol (hypercholesterolemia) and coronary heart disease — suggesting it may help cholesterol levels and heart health, though the evidence is preliminary. We don't have established effectiveness ratings in our data for the other three active ingredients, so we can't speak to what borage oil as a whole does beyond what oleic acid shows.

The evidence, ingredient by ingredient Borage Oleic Acid

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Oleic acid is generally recognized as safe in the amounts you'd get from foods like olive oil. At supplement-level doses, though, the safety picture in pregnancy and breastfeeding isn't well studied.

If you're pregnant, breastfeeding, or planning to be, talk with your doctor or pharmacist about whether this product is right for you, since concentrated supplement amounts of oleic acid haven't been thoroughly tested in these groups.

Side effects, ingredient by ingredient Borage Oleic Acid

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?
  • 1 of the 1 matched ingredient can interact with medications — Oleic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

If you take antidiabetes drugs (blood sugar medications), check with your doctor or pharmacist before using this product — oleic acid may increase how well these drugs work, which is a Moderate concern. No other medication interactions are documented for the ingredients we could check.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Borage Super GLA 300 may appeal to you if you're interested in fatty acid supplementation for heart health and cholesterol support — oleic acid has some preliminary evidence for both. If you take blood sugar medications, you should double-check this product with your doctor or pharmacist first, since oleic acid may enhance their effects.

Discuss it with your own healthcare provider before starting.

Borage seed 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.
