Fucoidan Umi No Shizuku's commitment

We make our best efforts in the selection of raw ingredients, quality control, proprietary blending as well as active ingredient research to offer a product that not only helps protect health but also boosts our customers’ confidence.

Our commitments:
Our Fucoidan is different in 6 different ways.
Commitment 1 Commitment 1
Fucoidan MIX AG
(Fucoidan + Agaricus)

Umi No Shizuku is the unique formula known as “Fucoidan Mix AG”. It’s a perfect blend of fucoidan and Agaricus, ingredients harvested from the sea and land, respectively. Agaricus is a fungus in the family of Agaricaceae, called “the mushroom of God” in Brazil. It is rich in health-supporting glucose in the form of polysaccharide β-glucan.

Ingestion of Fucoidan Mix AG (two types of fucoidan and Agaricus mycelium blended in a fixed ratio) yields a greater effect on protecting health without placing a burden on the body than taking fucoidan and Agaricus mycelium separately. Fucoidan Mix AG is the reason why people choose Umi No Shizuku Fucoidan from among many existing fucoidan products.

High quality ingredients of Umi No Shizuku

From raw ingredients to manufacturing, Umi No Shizuku Fucoidan is produced, within Japan, under strict quality control. We make efforts to maintain quality and safety every day.

  • Fucoidan is a rare ingredient, extracted in a ratio of 1 per 100 parts of unprocessed mozuku. Umi No Shizuku Fucoidan contains an extremely high level of fucoidan, extracted from mozuku that can be only be harvested in Okinawa.
  • The number of sulfate groups said to be the “life force” of fucoidan, decrease when fucoidan is extracted from dried mozuku in the manufacturing process. As Umi No Shizuku Fucoidan uses Okinawa mozuku and is processed immediately when harvested, it excels in both its fucoidan and sulfate group content.
