Anthocyanins are associated with reducing the risk of developing chronic cardiac diseases such as high blood pressure and heart attacks.

Lifestyle changes such as increasing physical activity, managing stress, stopping smoking and eating a healthier diet can prevent, treat and even sometimes reverse heart and circulatory diseases. There is growing evidence to suggest a diet containing anthocyanins may help reduce the risk of developing chronic cardiac diseases, such as high blood pressure and heart attacks.

Large population studies have shown that a higher anthocyanin diet was associated with:

  • 32% reduction in the risk of suffering heart attacks in young and middle-aged
  • 14% reduction in risk of developing non-fatal heart attacks in men
  • 8-12% reduction in the risk of developing high blood pressure

In addition, a major review published in 2017 concluded that eating a diet rich in anthocyanins was associated with a reduced risk of dying from all causes, and specifically from heart and circulatory diseases.

A 2019 study from King’s College London demonstrated that anthocyanins have a major role to play in how blood vessels in our bodies function, helping to lower blood pressure and improve blood flow.


The first pilot clinical study on Haskap berries was published by a team from the University of Reading in the European Journal of Nutrition, December 2018: A pilot dose–response study of the acute effects of Haskap berry extract (Lonicera caerulea L.) on cognition, mood, and blood pressure in older.

The study had a double-blind crossover design and looked at the acute effects of three Haskap berry doses and a sugar matched placebo on 20 older adults, age 62-81 years. Results showed improvements in cognition (word recall and recognition i.e. episodic memory effects) and diastolic blood pressure, with higher doses appearing more effective. The researchers wrote that the positive blood pressure result was probably caused by dilation of blood vessels, as observed in previous anthocyanin research.
