Let us single out six useful properties of black currant for human health, which have scientific evidence.

1. Black currant is rich in anthocyanins

Black currant contains a large number of different anthocyanins, and some studies show that it contains up to 15 unique types.

In addition to their role as a plant pigment, anthocyanins also have many health promoting properties. Studies have shown that anthocyanins can play a role in cancer prevention, heart health, obesity, and even diabetes.

They also act as antioxidants – compounds that neutralize harmful free radicals that damage cells and also prevent the development of chronic diseases.

Like black currants, other products rich in anthocyanins include berries, eggplants , red cabbage, and grapes. Inclusion of a large amount of these products in your diet will undoubtedly have a beneficial effect on your health.

Vitamin C also works as an antioxidant that helps prevent tissue damage caused by the effects of harmful free radicals, and may even reduce the risk of developing tumors, heart disease and stroke.

An extract of 10% concentration is able to block 95% of these viruses from sticking to the surface of cells in the human body.
