The sea buckthorn berry, which is grown in the Himalayan mountains, has hit shop shelves as a new superfruit to rival broccoli, apples and blueberries.
The berry, which contains vitamins A, B1, B2, E and up to 10 times the amount of Vitamin C found in oranges, is said to boost the brain function.
Antioxidants in the berries also help to fight obesity, teeth problems, acne, ageism, poor digestion and constipation. It is also said to keep the heart healthy.
Aside from the berry, the leaves and stem can be used to treat skin diseases.
Known to be the healthiest berries available, it is already a huge hit in the US where it has been hailed as a slimming aid.
It is now available in the UK as the drink Pep.
"The grocery trade has been asking us to innovate. This ingredient is new to the UK market," the Daily Express quoted Simon Hardy, of Drinks Brokers, as saying.
Tony Ferguson of food product manufacturers The Ingredients Consultancy, said: "You can, perhaps, classify sea buckthorn as a new superfruit."
