Research has shown that Haskap helps fight chronic oxidative stress which is associated with the development of many chronic diseases because they are rich in antioxidants.

Antioxidants are natural compounds found in certain foods, which can help our bodies fight the damage caused by potentially harmful chemicals called free radicals.

These free radicals are generated as a result of normal biological processes occurring every day in our cells. Too many free radicals and too few antioxidants can lead to a state known as oxidative stress, when damage can occur to DNA and other structures in our cells.  Oxidative stress is believed to play a role in the development of many chronic diseases.


Scientists have used different tests to measure the antioxidant content of Haskap berries compared with other fruits. They found that Haskap berries have up to three times the antioxidant content of blueberries, and higher levels than many other berries.

Haskap contains particularly high levels of antioxidants due to its thin double purple-blue skin.  This high antioxidant content helps Haskap berries survive harsh northern winters which are exceptionally challenging in Canada.  In addition, it is thought that by producing nutrient rich fruit the Haskap plants are better able to procreate and spread in search of less inhospitable climates.  This is the same principle as grape vines that struggle – they consequently produce some of the best wine.
