Supplementation with black currant seed oil has been shown to improve the functioning of the immune system by a moderate amount . This effect can take some months to appear. As we age, the production of prostaglandin E 2 in our body increases. This leads to a decline in immune function because of lower T cell function. Black currant seed oil provides our body with gamma linolenic acid and alpha linolenic acid ( omega -3 ) which reduces prostaglandin synthesis. As a result, the performance of immune system boosts up. As a result, regular supplementation with black currant seed oil can help our body deal with pathogens, like infections caused by bactera, virus and fungi. One can recover faster from flu and cold.

Black currant seed oil contains about 15 – 20 gm of gamma linoleic acid and about 12 – 14 gm of alpha linoleic acid ( omega -3 ). These two nutrients are strongly anti-inflammatory and impart the most health benefits. Linoleic Acid is omega – 6 and it is the principal fatty acid in this oil. Omega-6 is about 44 – 51 %. This fatty acid is pro-inflammatory. Therefore, intake of higher amount of black currant seed oil may aggravate inflammation in the body, whereas when taken in small amount, it is strongly anti-inflammatory. In most commercial black currant seed oil, gamma linolenic acid concentration is increased using a process called refinement.
Vitamin E in Black Currant Seed Oil
This oil has significant amount of Vitamin E. However, it is disproportionately divided among tocopherols and tocotrienols. Most of the Vitamin E in black currant seed oil is found only in tocopherol forms .
- α – Tocopherol – 36.9 g/kg
- γ – Tocopherol – 55.4 g/kg
- δ – Tocopherol – 6.9 g/kg
Due to presence of Vitamin E, it provide the health benefits of this Vitamin. Black currant seed oil thus acts as an antioxidant. It protects the nerves from damage and also safeguards gene expression, which are all functions of Vitamin E.
Sterols in Black Currant Seed Oil
This oil also contains small amounts of plant sterol compounds, also known as phytosterols. These provide health benefits even in small concentrations. These are the phytosterols found in black currant seed oil .
- Campesterol – It is strongly anti-inflammatory and lowers the degeneration of cartilage in arthritis.
- Stigmasterol – Anti-cancerous compound. It also lowers blood glucose and exerts an effect on the thyroid hormone.
- β – Sitosterol – This phytosterol reduces cholesterol levels in blood.
