Science and Health
The rapid spread of computers and cellular phones in the home and workplace has led to an increase in eye fatigue and discomfort, blurred vision and myopia. Scientific studies have shown that the consumption of blackcurrant extracts containing high amounts of rutinoside anthocyanins will reduce eye fatigue.

Many people suffer from poor circulation. An important scientific study showed that blackcurrant anthocyanins might lessen muscle stiffness by increasing peripheral blood flow and reducing muscular fatigue.
