Vitamin C, also known as ascorbic acid, is a water-soluble nutrient found in some foods. Humans are unable to make Vitamin C in their bodies and need to obtain this essential nutrient through their diets.


Permitted health claims for Vitamin C include:

  • Vitamin C contributes to the protection of cells from oxidative stress
  • Vitamin C contributes to the normal function of the immune system
  • Vitamin C contributes to normal functioning of the nervous system
  • Vitamin C contributes to normal collagen formation for the normal function of blood vessels
  • Vitamin C contributes to normal energy-yielding metabolism


The table below shows that the fresh haskap berries along with oranges are considered to be Vitamin C high foods compared to other fruits.

Pronounced an-tho-sigh-an-ins (from the Greek anthos, a flower, and kyanos, dark blue).
Anthocyanins in food are naturally occurring plant pigments that give fruit and vegetables their deep purple, blue and red colours.
Haskap berries contain up to four times more anthocyanins than blueberries.
Haskap berries have a unique anthocyanin profile, with one specific anthocyanin called cyanidin-3-glucoside, known as C3G, making up around 85% of the total anthocyanin content.

This image compares the green flesh of the blueberry with the deep crimson flesh of the haskap berry. It's the combination of blue skin and juicy red flesh that give haskaps such a high anthocyanin content.


Antioxidants in food 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. The mismatch of 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. It is thought antioxidants in our diet can help fight chronic oxidative stress associated with the development of these 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.

The graph below shows the antioxidant capacity of haskap berries compared to other fruits using the FRAP method:

The nutritional content of the haskap berry has created significant scientific interest. Investment in high level research studies investigating nutrition, health benefits and farming have been commissioned by Haskapa at top universities.  
The first peer reviewed haskap berry pilot clinical study was published by a team from the University of Reading in the European Journal of Nutrition in December 2018.

Haskapa is currently working with a UK university sports nutrition department to research the effect of haskap berry supplementation on exercise endurance.
Haskap berries contain a range of phytochemicals which have the potential to mitigate the development of exercise-induced oxidative stress and improve exercise performance.
