HelloPharmacist Scorecard of Evening Primrose with Black Currant Seed Oil by ProCaps Laboratories
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
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
The stated purpose hasn't been mapped to our evidence data yet.
Why this rating?
- We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
Every active ingredient lists its own amount on the label.
Why this rating?

- “Evening Primrose Oil” is listed as a grouped ingredient — the label gives one combined amount (500 mg) without saying how much of each component you get.
- “Black Currant seed Oil” is listed as a grouped ingredient — the label gives one combined amount (900 mg) without saying how much of each component you get.
- “Essential Fatty Acid Profile” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.
Why this rating?
- 2 of the 3 matched ingredients can interact with medications — Docosahexaenoic Acid (dha), Oleic Acid.
- The most serious interaction on file is rated Moderate.
- Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
- For scale: 375 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.
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 2 of the 3 matched ingredients.
- Pregnancy & breastfeeding safety ratings cover 3 of 3.
- General safety write-ups exist for 3 of 3.

General Statements
Andrew Lessman’s EVENING PRIMROSE with BLACK CURRANT SEED OIL provides a concentrated blend of Essential Fatty Acids (particularly GLA) from Evening Primrose and Black Currant Seed oils to gently support women through the menstrual cycle. Just like vitamins, there are certain fatty acids your body cannot produce, yet are essential for optimum health and therefore must be obtained through your diet or supplementation. Used traditionally in America and in Europe to support women’s health, Evening Primrose and Black Currant oils contain high levels of Gamma Linolenic Acid (GLA), an essential Omega-6 fatty acid, and an important precursor to hormone-like substances in the body called prostaglandins. Evening Primrose Oil has been shown to support GLA levels and help to alleviate the mood swings and physical discomfort associated with premenstrual syndrome (PMS) for some women. Since Evening Primrose and Black Currant oils, along with fatty acids in general, are quite unstable and are prone to oxidation, in order to preserve their benefits it is important to deliver them in a manner that reduces oxidation and instability. Accordingly, we have developed our liquid-filled softgel capsules to protect against the damaging effects of oxidation on potency. Our unique, protective softgels also avoid the additives present in ordinary softgel capsules. Our softgels are the perfect way to protect and enjoy the benefits of the delicate oils in Evening Primrose with Black Currant Seed Oil.

For each ingredient in Evening Primrose with Black Currant Seed 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.
Omega-3 Fatty Acids
Anticoagulant/Antiplatelet Drugs
Theoretically, DHA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Although some clinical evidence suggests that DHA might reduce collagen-stimulated platelet aggregation and thromboxane release, most clinical evidence suggests that DHA alone does not affect blood clotting. However, theoretically, when given in combination with EPA as fish oil, concomitant use with anticoagulant or antiplatelet drugs (including aspirin) might increase risk of bleeding.
Antidiabetes Drugs
Theoretically, taking DHA with antidiabetes drugs might reduce the effects of these medications.
In people with type 2 diabetes, including those taking oral hypoglycemic medications, DHA seems to increase fasting blood glucose levels.
Antihypertensive Drugs
Theoretically, taking DHA with antihypertensive drugs might increase the risk of hypotension.
Fish oils containing DHA can lower blood pressure and might have additive effects in patients treated with antihypertensives; use with caution.
Evening Primrose Oil
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.
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.
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.
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.
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.
Black Currant seed Oil
Anticoagulant/Antiplatelet Drugs
Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.
Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet effects.
Phenothiazines
Theoretically, black currant seed oil might increase the risk of seizure in patients receiving phenothiazines.
Black currant seed 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, although there is no evidence that black currant seed oil causes seizures. 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 4 grams daily, which contains GLA, was added. One of these patients had a prior history of seizures.
