Blackcurrants contain anthocyanins, which are compounds naturally found in berries. They are very potent antioxidants and are responsible for the colour of blackcurrants. Around 300 different types of anthocyanins have been discovered.
Anthocyanins inhibit the enzymes Cyclo-oxygenase 1 and 2, and reduce inflammation and the effects of arthritis in the body. The effect is similar to aspirin or ibuprofen, so many people are choosing the healthier blackcurrant juice over these drugs.
In particular, blackcurrants are renowned for their high content in Vitamin C (a powerful antioxidant), GLA (Gamma-Linoleic Acid, a very rare Omega-6 essential fatty acid) and potassium. They have been shown to have twice the potassium of bananas, four times the vitamin C of oranges, and twice the antioxidants of blueberries.
