Haskap nutrition

With three times the antioxidant capacity of the high-bush blueberry1, packed with vitamin C2 and high levels of anthocyanins and other phenolic compounds3, we believe haskaps are one of the most important and exciting new berry discoveries. We have compiled information from the scientific literature, are undertaking our own research into the berry’s health properties and constantly improving our processes to maintain the bioactive compounds in our value-added products. The information on this page is taken from a number of scientific studies and shows analysis of the fruit, not of any value-added or processed products. It is also important to note that nutritional properties vary with cultivar, degree of ripeness, growing location and practice,and soil.

What are antioxidants?

As the name implies, antioxidants are substances that are capable of counteracting the damaging, but normal, oxidative effects of free radicals in the body. There are different types of antioxidants found in the diet, e.g. vitamins (C and E), micronutrients (zinc), and polyphenols (flavonoids). Antioxidants are found in high concentrations in haskap berries.

So what are free radicals?

Free radicals are by-products generated in our body as a result of normal physiological processes. They are beneficial at low or moderate concentrations and are involved, for example, in our defense against infectious diseases. However, the overproduction of free radicals associated with low concentrations of antioxidants, has negative effects on health and is believed to play a role in the development of degenerative diseases such as cancer, heart disease, stroke, Alzheimer’s disease, Rheumatoid arthritis, and cataracts4.

Why should I consume Vitamin C?

Vitamin C is recognized as an essential micronutrient due to the important role it plays in human health. In addition to its action as an antioxidant, it is involved in synthesis and maintenance of a protein called collagen, which helps to speed up the recovery of healing wounds and injuries and promotes less visible scars5. Research has indicated that some haskap berry varieties can have higher content of vitamin C than oranges and blueberries6.

What about Potassium?

Potassium works with sodium to balance the vascular fluid and promote vasodilation, which can have a beneficial effect by lowering blood pressure and reducing the risk of cardiovascular diseases7. Haskap is also a great source of potassium, a very important nutrient for heart, kidney, and bone health.

what are Polyphenols?

Polyphenols are metabolites produced by plants. They have strong antioxidant activity and are an integral part of our diet. Among polyphenols, flavonoids (such as anthocyanins and flavonols) are an important class of bioactive compounds that have been associated with several health-promoting benefits.


Anthocyanins are red, blue, and purple natural pigments with significant biological activity, found in high concentrations in haskap berries; up to 13 times more than blueberries. The main anthocyanin in haskaps is called cyanidin-3-glucoside, known as C3G.6 There is growing evidence from large prospective cohort studies that eating a diet rich in anthocyanins is beneficial in reducing the risk of heart attacks, non insulin dependent diabetes, high blood pressure and even erectile dysfunction.8-10
