HelloPharmacist Scorecard of Black Currant Oil by Health From The Sun

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

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.
  • “Black Currant seed Oil” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This softgel contains five active ingredients sourced from black currant seed oil: gamma-linolenic acid, linoleic acid, oleic acid, alpha-linolenic acid, and stearidonic acid. These are all fatty acids — building blocks that play roles in how your body handles inflammation and cholesterol.

The capsule itself is made from vegetable-based material, and the formula includes inactive ingredients like corn starch, carrageenan, glycerin, sorbitol, and water to hold everything together.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Omega-3 and omega-6 fatty acid source.
  • We looked for evidence on: Atopic dermatitis (eczema), Coronary heart disease (CHD), Dry eye, Hypercholesterolemia, Hyperlipidemia, Hypertension — and 4 related terms.
  • The strongest evidence on file: Oleic Acid is rated "Possibly Effective" for Coronary heart disease (CHD) (Natural Medicines).
  • Also on file: Oleic Acid is rated "Possibly Effective" for Hypercholesterolemia.
  • Also on file: Oleic Acid is rated "Insufficient Reliable Evidence To Rate" for Hypertension.

Oleic acid — one of the active components — is rated possibly effective for high cholesterol (hypercholesterolemia) and coronary heart disease. The evidence we hold doesn't establish how well the other ingredients in this product work on their own.

The evidence, ingredient by ingredient Black Currant 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 from food sources like olive oil is generally well tolerated. Concentrated supplements haven't been studied thoroughly in pregnancy or while breastfeeding, so there isn't enough data to know either way.

Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or breastfeeding. No serious side effects were reported in the data we reviewed.

Side effects, ingredient by ingredient Black Currant 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 any antidiabetes drug — including insulin, metformin, or sulfonylureas — double-check with your doctor or pharmacist before starting this product. Oleic acid may increase how well these medications work, which could lower your blood sugar more than intended.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

This product may be worth considering if you're interested in oleic acid's possible benefits for cholesterol and heart health. If you take any diabetes medication, check with your doctor or pharmacist first — oleic acid might strengthen its effects.

It's a good idea to discuss this supplement with your healthcare provider before adding it, especially if you're on any prescription medications.

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.

Likelihood Possible Evidence D
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.

Black Currant Oil by Health From The Sun: Common Questions

Does Black Currant Oil by Health From The Sun interact with any medications?
Yes. Based on its ingredients, Black Currant 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?
Black Currant Oil contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 are gamma-linolenic acid and the other fatty acids in here?
They're fatty acids sourced from black currant seed oil. Oleic acid is the one we have effectiveness data for — it's possibly effective for high cholesterol and heart disease. The others (gamma-linolenic acid, linoleic acid, alpha-linolenic acid, and stearidonic acid) are active ingredients too, but we don't have established effectiveness ratings for them yet.
Can I take this if I'm on diabetes medication?
Not without checking first. Oleic acid may increase how well your antidiabetes drugs work, which could drop your blood sugar lower than expected. Talk with your doctor or pharmacist before starting — they'll know your exact medication and whether it's safe to combine.
Is this safe to take while pregnant or breastfeeding?
The safety data for supplement-level doses isn't solid enough to know either way. Food amounts of oleic acid are considered fine, but concentrated supplements haven't been well studied in pregnancy or lactation. Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding — they can give you personalized advice.
Does this have any side effects?
No serious side effects were reported in the data we hold. Oleic acid from food sources is generally well tolerated.
How many active ingredients are in each capsule?
Five: gamma-linolenic acid, linoleic acid, oleic acid, alpha-linolenic acid, and stearidonic acid. The rest of the formula is inactive ingredients that help hold the capsule together.
