How are we different?

Our unique brown algae extract is derived from wild Ecklonia bicyclis growing in the natural coastal regions of South Korea. Our partner farm ensures the careful handling of the wild brown algae throughout its entire production: the algae is first gently harvested by hand from March through June, then gently extracted using pure water at low temperatures in a 25:1 ratio. This enables the producer to standardise the polyphenol content to 50% and to guarantee the preservation of the brown algae's phlorotannins. No other solvents (e.g., methanol or acetone) are used.

This particularly pure Ecklonia bicyclis extract is complemented by the addition of our Hawaiian spirulina (Spirulina platensis pacifica). We are the only supplier on the market that offers spirulina without the introduction of any additives throughout the entire production process.

The tropical climate and the near-constant unclouded sunlight guarantees high-quality spirulina all year round, and the sophisticated, biologically balanced and constantly controlled equilibrium in the open-air cultivation tanks prevents the growth of foreign algae. The Ocean-Chill spray drying, a very gentle process conducted at low temperatures, ensures that the spirulina remains raw. The raw spirulina is then immediately packed into airtight amber glass bottles. Contrary to many other manufacturers, our spirulina is not preserved via irradiation.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.

Ecklonia bicyclis

Ecklonia bicyclis, also known as arame or Eisenia bicyclis, is a species of brown algae found mainly in the Pacific Ocean in the coastal regions of southwestern Japan and Korea as well as of southeastern China. Growing beneath the surface of the water, of course, this species can sprout a stem up to one metre long, from which two frond-like leaf structures extend into the air. These leaf structures grow annually and are usually harvested and processed by hand from March through June. Ecklonia bicyclis is a well-known and popular ingredient in Japanese and South Korean cuisine.

Brown algae from the Ecklonia genus are rich in polyphenols, of which their phlorotannins are particularly noteworthy. Phlorotannins are natural polyphenols that are found in large amounts in brown algae. What is special about the bicyclis species is the structure and complexity of its phlorotannins. While they share the phlorotannins eckol, bieckol, dieckol and phlorofucofuroekol with other Ecklonia species, they also harbour another rare phlorotannin called phloroglucinol.

Spirulina platensis from DaWu Mountain

This Spirulina platensis is the only one in the world grown in the clean, fresh, mineral-rich mountain spring water of DaWu Mountain. The non-GMO algae is cultivated without the use of plant protection products or chemical fertilisers, and the warm, tropical climate and fresh air provide optimal growing conditions all year round. Instead of relying on artificial fertilisers or the addition of synthetic minerals, the fresh spring water from DaWu Mountain provides a rich supply of minerals and trace elements, which accumulate organically in the algae.
