Black currant seed oil is a nutrient-rich plant oil made by pressing or extracting the tiny seeds of the black currant berry, scientifically known as Ribes nigrum. Unlike black currant juice or fruit extract, the seed oil is especially valued for its fatty-acid profile, including gamma-linolenic acid (GLA), alpha-linolenic acid (ALA), and linoleic acid.
Because of this unique composition, black currant seed oil has attracted interest for skin health, inflammatory conditions, cardiovascular wellness, and general nutrition. However, many of the commonly advertised benefits still require stronger and larger human studies.
This guide explains what black currant seed oil is, its nutritional composition, potential benefits, possible side effects, dosage, uses, storage, precautions, and what current research actually tells us.
What Is Black Currant Seed Oil?
Black currant seed oil is an edible vegetable oil extracted from the seeds of the black currant fruit (Ribes nigrum), a small dark-purple berry native to parts of Europe and Asia.
The oil is different from black currant fruit juice because it contains concentrated amounts of polyunsaturated fatty acids rather than the fruit’s water-soluble compounds.
Research shows that black currant seed oil commonly contains approximately 40–48% linoleic acid, around 11–18% gamma-linolenic acid, and roughly 10–15% alpha-linolenic acid, although the exact composition can vary depending on the variety and extraction method.
It may also contain smaller amounts of oleic acid, stearidonic acid, tocopherols, carotenoids, and other naturally occurring compounds.
One of its most interesting components is gamma-linolenic acid (GLA), an omega-6 fatty acid that is also found in oils such as evening primrose and borage oil. Black currant seed oil is available as a liquid oil or in softgel capsules. It may be marketed as a nutritional supplement or as an ingredient in skincare products.
Nutrition Facts of Black Currant Seed Oil
Black currant seed oil is almost entirely fat, so it does not provide meaningful amounts of protein, carbohydrates, or fiber. Its nutritional value comes primarily from its fatty acids and minor bioactive compounds. The following is an approximate nutritional profile; actual values vary by product and extraction method.
| Nutrient | Approximate Amount |
|---|---|
| Calories | About 120 kcal per 1 tablespoon |
| Total Fat | About 14 g |
| Saturated Fat | Generally less than 2 g |

Studies have found that the fatty-acid profile can vary considerably between samples, but linoleic acid, GLA, and ALA are consistently among the major components.
20 Proven Benefits of Black Currant Seed Oil
1. Provides Essential Fatty Acids: Black currant seed oil supplies polyunsaturated fatty acids, including linoleic acid and alpha-linolenic acid, which contribute to normal cellular and physiological functions.
2. Provides Gamma-Linolenic Acid: Black currant seed oil is a natural dietary source of GLA, an omega-6 fatty acid that the body can metabolize into other fatty acids involved in signaling pathways.
3. Supports Skin Barrier Function: Its fatty acids may help support the lipid structures involved in maintaining the skin barrier, although clinical evidence for treating specific skin diseases remains limited.
4. May Support Dry Skin: Oils rich in essential fatty acids may help moisturize and improve the feel of dry skin when appropriately incorporated into topical products.
5. May Help Maintain Skin Comfort: The oil’s fatty-acid composition has generated interest in its potential to support irritated or sensitive skin, although it should not replace dermatological treatment.
6. May Support Joint Comfort: Some research has investigated GLA-rich oils for rheumatoid arthritis symptoms, and a clinical trial specifically involving black currant seed oil reported some improvements in disease activity measures, although overall clinical responses were not clearly superior across all outcomes.
7. May Have Anti-Inflammatory Potential: GLA can participate in biochemical pathways related to inflammatory mediators, which is one reason black currant seed oil has been studied in inflammatory conditions.
8. Supports Normal Cell Membranes: Polyunsaturated fatty acids are incorporated into cell membranes and contribute to their normal structure and function.
9. May Support Cardiovascular Health: Early research has investigated black currant seed oil in relation to blood-pressure responses and lipid metabolism, but the evidence is not strong enough to consider it a cardiovascular treatment.
10. Provides Plant-Based Omega-3 ALA: Black currant seed oil contains alpha-linolenic acid, a plant-based omega-3 fatty acid that is an essential dietary fat.
11. Contains Antioxidant-Related Compounds: Black currant seed oil can contain tocopherols and other minor compounds that contribute antioxidant activity, although its composition varies among products.
12. May Support Normal Immune Function: Research has examined black currant seed oil’s influence on immune responses, including a controlled study in older adults, but this does not establish that supplementation prevents infections.
13. May Support Skin Research in Atopic Conditions: Black currant seed oil has been investigated in relation to atopic dermatitis, including a randomized trial in mothers and infants that found a temporary reduction in atopic dermatitis prevalence at 12 months but not at 24 months.
14. May Influence Fatty-Acid Metabolism: Supplementation has been shown to alter the levels of certain fatty acids in blood lipids, including GLA-derived fatty acids.
15. May Complement a Balanced Diet: Used in appropriate amounts, black currant seed oil can provide additional unsaturated fats as part of an overall balanced eating pattern.
16. May Support Normal Skin Lipid Balance: Linoleic acid is an important component of skin lipids, making oils containing substantial linoleic acid of interest for maintaining healthy skin.
17. May Be Useful in Plant-Based Nutrition: Black currant seed oil provides ALA and GLA without relying on animal-derived oils, making it an option for people seeking plant-based sources of fatty acids.
18. May Support Healthy Aging Research: Its fatty acids and minor antioxidant compounds have prompted research into cellular and inflammatory processes associated with aging, although human evidence for anti-aging effects is still limited.
19. May Support Overall Fatty-Acid Intake: Because it contains several unsaturated fatty acids, the oil can contribute to dietary fatty-acid diversity when used appropriately.
20. May Have Potential for Future Therapeutic Research: Black currant seed oil continues to be studied for inflammatory, dermatological, cardiovascular, and nutritional applications, but larger and better-designed clinical trials are needed before specific medical claims can be made.
10 Side Effects of Black Currant Seed Oil
Black currant seed oil is generally well tolerated when used appropriately, but supplements can still cause unwanted effects, particularly at higher amounts.
