Frequently Asked Questions

A1 Fucoidan is a slime component peculiar to mozuku, the mekabu portion of wakame, kelp, and other seaweeds, and is a type of water-soluble dietary fiber. It is composed primarily of the sugar fucose sulphate, a high molecular polysaccharide. The highest fucoidan content is said to be found in Okinawa mozuku.

A6 UMI NO SHIZUKU Essential Nutrition does not contain fucoidan. Essential Nutrition contains enzymes, essential amino acids, vitamins, and more that are required to supplement health.
A7 Fucoidan is found naturally in a high molecular state with many bound sugars. When made into a low molecular state, the properties of fucoidan change.
