Blackcurrants (Ribes nigrum L.) are small, black, berry-like fruits native to central Europe and northern Asia. Today, they are cultivated in parts of the world with a temperate climate (1).

The fruits are rich in vitamin C, organic acids, and essential oils besides the other micro and macronutrients. Hence, they taste acidic but sweet. Moreover, they have phenolic compounds with antioxidant and antimicrobial properties (1).

The leaves of blackcurrants contain unique quercetin derivatives. These active molecules also contribute to the anti-inflammatory, antiviral, and antiseptic effects (1).

Traditional medicine uses its extracts to manage a variety of disorders, including cancer. Today, there is a volume of clinical studies that show positive effects of blackcurrants on heart, brain, and kidney diseases (1), (2).

What Are The Benefits Of Blackcurrants?

Blackcurrants can protect your digestive, circulatory, nervous, and excretory systems. These fruits have been extensively studied for their properties that support cancer prevention.

1. Have Anti-inflammatory Effects

Inflammation may cause heart, liver, and kidney diseases. It may also induce arthritis, urinary tract infections (UTIs), and neurodegenerative disordersi  Diseases that are caused due to damage to the cells of the nervous system and affect specific body functionalities. (Alzheimer’s disease, dementia, etc.). Including foods rich in anti-inflammatory compounds in your diet can prevent/reduce the severity of this phenomenon.

Anthocyanins are a class of polyphenols predominantly found in blackcurrants. Blackcurrant extracts suppress the activation of pro-inflammatory components in your immune system (3).

These molecules target specialized cells like macrophages. This prevents several inflammatory disorders from worsening (4).

2. Soothe The Stomach And Aid Digestion

These berries are abundant in flavonoids. These phytochemicals have been shown to cause smooth muscle relaxation. Blackcurrant extracts could relax contractions in the GI tract, according to animal studies (5).

Studies confirm the antispasmodic activity of these fruits. Quercetin, myricetin, and other flavonoids inhibit spasms in the stomach and intestines. Also, blackcurrant leaves have been used in folk medicine to treat diarrhea (6).

3. Boost Kidney Health

The antioxidant and anti-inflammatory effects of blackcurrants prevent chronic kidney disorders. They protect your excretory system from inflammation and infections. The extracts also inhibit the formation of kidney stones (7).

Blackcurrant juice/tea makes your urine more alkaline (increases its pH). It also promotes the excretion of excess citric acid and oxalic acid from your body. If not, these two acids can react to form kidney stones when left to pile up (8).

A hundred grams of black currants has about 4.3mg of oxalate. That makes these fruits safe for individuals with kidney disorders and bladder stones (9).

4. Lower Blood Cholesterol Levels

High levels of LDL (bad) cholesterol elevate the risk of cardiovascular, liver, and other metabolic disorders. Research shows that diets rich in anthocyanins cause a decrease in total cholesterol and LDL levels. They also increase serum HDL (good) cholesterol levels and improve cardiovascular health (10). 

Animal studies with blackcurrant extracts are supporting evidence to this effect. Subjects treated with this extract showed significantly lower cholesterol levels than the untreated/control ones (11).

Moreover, blackcurrant juices are abundant in antioxidants. These juices prevent the oxidation of lipids in your body (12). This way, they can prevent/delay the onset of obesity and chronic conditions like atherosclerosisi  Narrowing of the artery walls due to the deposition of fats and other substances, which can lead to heart attack or stroke. and Alzheimer’s.

5. Have Antidiabetic Effects

Blackcurrant has anthocyanins like cyanidin 3-rutinoside, delphinidin 3-glucoside, and peonidin 3-rutinoside. When consumed in fair amounts, these phytochemicals improve insulin sensitivity, particularly in individuals with type 2 diabetes (13).

Carbohydrate-metabolizing enzymes (like α-Glucosidase and pancreatic α-amylase)  are the targets of anthocyanins. They block the activity of these enzymes. As a result, the rapid breakdown of carbohydrates is slowed down. Ultimately, anthocyanins can prevent sudden spikes in your blood sugar/glucose levels (14).

6. May Help Manage Eye Disorders

The black currant anthocyanins improve the functions of your eyes/vision. These molecules increase the blood flow in the optical nerves and eyes. Regular consumption of such foods and supplements may decelerate the loss of vision or related symptoms in patients with glaucomai  Eye disease caused due to progressive damage to the optic nerve and increasing pressure on the eyeball, leading to loss of vision. (15).

Anthocyanins may have positive effects on chronic eye ailments. These include diabetic retinopathyi  Impairment or loss of vision caused due to the damage of retinal blood vessels in diabetic patients. , retinal vein occlusioni  A condition that can cause sudden or permanent loss of vision due to clot formation in the veins that carry blood back from the retina. , and retinal artery occlusion (15).

These active molecules are absorbed and transferred beyond the blood-retina barrier when taken orally. They reach various parts of the ocular tissues and preserve their function. Thus, blackcurrants or their extracts can slow down the effects of aging and disease on eyes (15).

7. Protect Your Brain

Like vitamin C, black currant extract inhibits lipid peroxidation in your body. Experimental studies report about 65% inhibition, thanks to its antioxidant capacity. This activity is most beneficial in protecting your central nervous system (CNS) and improving brain function. (16), (17).

In the absence of this effect, free radicals accumulate in your system. Free radicals are known to trigger neurodegenerative diseases, including Alzheimer’s, Huntington’s, and Parkinson’s diseases (18).

Usually, the accumulation of free radicals leads to inflammation of the brain cells (neurons). Blackcurrants reduce neuroinflammation because they contain anti-inflammatory molecules. A cumulative effect of these properties causes improved memory, learning, and cognitive abilities (18).

8. May Promote Liver Health

Alcohol abuse causes permanent changes in the structure and function of liver cells. The proteins and phospholipids get structurally modified. This may have a direct effect on the liver’s functionality (19).

Another problem that stems from alcohol abuse is the formation of free radicals/reactive oxygen species (ROS). These ROS can react with phospholipids in the liver cell membranes and trigger inflammation (19).

Adding polyphenol-rich foods like blackcurrants to your diet can pause/stop such detrimental effects. Blackcurrants protect the structural lipids and proteins from the attack by ROS (19).

In several animal studies, the skins of these berries show anti-proliferative effects on cancerous liver cells (20).

9. Repair And Nourish Skin

Various skin diseases arise due to inflammation, infections, or aging. They leave you with dry skin, lesions, itching, redness, scabs, etc. Atopic dermatitis is an example of a serious skin condition seen in children and adults (21).

Your skin would need intense repairing and conditioning in such cases. Clinical studies discovered a specific polysaccharide in blackcurrants that exerts anti-inflammatory effects. This molecule controls the production of inflammatory compounds by your immune system (21).

Blackcurrant seeds contain good amounts of fatty acids, like linolenic acid. Their oil suppresses the inflammation mediators in your skin. So, blackcurrants and the seed oil can nourish and nurse your skin to health without any side effects (21), (22).

10. Possess Antimicrobial Properties

Recent studies have reported potent antiviral properties in the leaves of wild blackcurrants. Their extracts can particularly eliminate Influenza A viruses (IAV) that cause highly contagious human diseases. The typical symptoms of IAV infections are fever, sore throat, headache, muscle pain, and nasal inflammation (23).

The leaf extracts prevent the entry and internalization of these viruses at the molecular/genetic level. The essential oil of these leaves also has antibacterial and antifungal properties.

Active compounds like caryophyllene, sabinene, terpinolene, ocimene were identified in this oil. Escherichia coli, Streptococcus faecalis, Staphylococcus aureus, Candida albicans, and Trichophyton mentagrophytes are a few microbes susceptible to blackcurrant seed oil treatment (24).

Joannan, a lifestyle blogger, shared how much she loved drinking blackcurrant juice to treat the flu. She said, “In Finland when you have flu you take homemade hot black currant juice with brown sugar. When I came to Ecuador there were no black currants.And I missed my hot black currant juice with brown sugar with its terrible tart taste that would instantly make me feel better (i).”


  • By weight, black currants contain 3-4 times more vitamin C than oranges. The levels of antioxidants are twice that of blueberries (25).
  • Blackcurrant and its derivatives are said to ease menstrual discomfort. Issues like PMS can be effectively treated with these products. However, there is not enough practical evidence supporting this application.
  • Blackcurrant seed oil is known for its anti-inflammatory effects. It contains essential fatty acids that help in managing debilitating conditions like rheumatoid arthritis and morning joint stiffness (26).

 It is equally important to know the nutrients responsible for these mind-blowing benefits. A powerful phytonutritional composition is the answer.
