Home / Kiwifruit Powder ExtractKiwifruit Powder Extract Description DescriptionKiwifruit powder is the dried form of the kiwi fruit, the Actinidia Chinensis. The powder extract contains the same great benefits of eating a kiwi fruit, but it is a few times more powerful than the fruit, and it is very convenient. The high concentration in vitamin C, and one of the key constituents in kiwi, actinidin, make it a great food. It is believed that the polyphenols and vitamin C are responsible for its anti asthmatic properties. However, its great prebiotic properties might have a great role in this, as intestinal health is known to be linked to asthma. Kiwi contains prebiotic soluble fiber, which selectively stimulates good bacteria in our intestine.
