HelloPharmacist Scorecard of Borage Oil by Vital Nutrients

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Borage Oil by Vital Nutrients contains two active ingredients: gamma-linolenic acid and borage seed oil, cold-pressed. Both are derived from the borage plant seed and deliver essential fatty acids your body uses for cell function and inflammation control.

The softgel capsule itself is made from gelatin, glycerin, water, and mixed tocopherols (a form of vitamin E that acts as a preservative).

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

This is a single-ingredient Borage product and its label doesn't state a use — see Borage's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for borage oil is mixed and limited. For atopic dermatitis (eczema), the data we have rates it as possibly ineffective — meaning current studies don't support its use for that condition.

For attention deficit-hyperactivity disorder (ADHD), acute respiratory distress syndrome (ARDS), and alcoholism, there isn't enough reliable evidence to know either way. If you're considering this product for a specific health goal, talk with your doctor about whether the current evidence supports it for your situation.

The evidence, ingredient by ingredient 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 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.

Borage seed oil is generally well tolerated when taken by mouth. The most common side effects are mild digestive ones: belching, bloating, diarrhea, and soft stools.

The bigger safety concern is pyrrolizidine alkaloids (PA), naturally occurring compounds in some borage plant parts — while borage seed oil contains little to none, other parts of the plant can damage your liver, especially with long-term use. Look for a product certified PA-free to lower that risk.

During pregnancy and breastfeeding, borage oil is rated as likely unsafe because of the possible liver-toxic alkaloids and theoretical risks, so avoid it during these times — talk with your doctor if you're pregnant, planning pregnancy, or nursing.

Side effects, ingredient by ingredient 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?
  • 1 of the 1 matched ingredient can interact with medications — Borage.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 227 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 (warfarin, aspirin, clopidogrel) — Moderate risk of increased bleeding. Also verify if you're on phenothiazines (antipsychotics like chlorpromazine) or drugs that induce the liver enzyme CYP3A4 — both carry Moderate theoretical interaction risks.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Borage oil may be worth considering if you're interested in essential fatty acids, but it's not proven effective for the conditions most people ask about (eczema, ADHD). If you take blood thinners, antipsychotics, or certain liver-enzyme-inducing drugs, you'll need to clear it with your doctor or pharmacist first.

Pregnant or breastfeeding — skip it. Make sure any product you choose is certified free of pyrrolizidine alkaloids.

Borage Seed Oil, Cold-Pressed3 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 by Vital Nutrients: Common Questions

Does Borage Oil by Vital Nutrients interact with any medications?
Yes. Based on its ingredients, Borage Oil has a known interaction with 226 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Borage Oil contains 2 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.
What's gamma-linolenic acid, and why is it in this product?
Gamma-linolenic acid (GLA) is a fatty acid your body uses to manage inflammation and cell function. It's a natural component of borage seed oil, so it comes along when you take this supplement. We don't have separate safety or interaction data for GLA on its own, but it's one of the active compounds that makes borage oil work.
Can I take this if I'm on a blood thinner like warfarin?
Not without checking first. Borage seed oil may increase your bleeding risk when combined with blood thinners or antiplatelet drugs — the gamma-linolenic acid in it can reduce platelet clumping. Talk with your doctor or pharmacist before adding this product to your routine.
Is this product certified free of pyrrolizidine alkaloids?
The product facts don't specify whether this particular brand is PA-certified. Borage seed oil itself contains little to none of these toxic compounds, but it's smart to look for a PA-free certification on the label or contact the manufacturer to confirm.
What are the most common side effects?
Belching, bloating, diarrhea, and soft stools are the most common side effects when taken by mouth. These are usually mild and digestive in nature. The serious concern is liver damage from pyrrolizidine alkaloids in other borage plant parts, which is why seed oil that's PA-free is the safer choice.
Does borage oil really work for eczema?
Not according to the evidence we have — it's rated as possibly ineffective for atopic dermatitis (eczema). If you're looking for a supplement to help with eczema, talk with your doctor about treatments with stronger evidence behind them.
Can I take this while pregnant or breastfeeding?
No — borage oil is rated as likely unsafe during pregnancy and lactation because of the possible liver-toxic alkaloids and theoretical risks to the uterus and nursing infant. Avoid it during these times and talk with your doctor if you have questions about alternatives.
