A.Fucoidan is a naturally occurring polysaccharide found in the slimy components of seaweeds such as mozuku and kelp. This slimy substance protects seaweed from external stresses such as strong tides, ultraviolet rays, drying, and bacteria. Recent research suggests that these protective properties may also support human health.
A.Due to legal regulations, we cannot describe specific effects or medical claims. We recommend researching fucoidan through published studies and books to understand its characteristics.
A.Fucoidan AF Premium is characterized by a high concentration of active components, the use of high-purity raw materials, inclusion of ascophyllan and fucoxanthin, and manufacturing in ISO-certified facilities. It is also formulated as a nutritional functional food containing amino acids and vitamins such as B1, B2, and B6.
A.Fucoidan Kenkodo has over 30 years of experience in health food sales and more than 15 years specializing in fucoidan products. We continuously research and develop higher-quality formulations, using Okinawa mozuku-derived fucoidan with high purity and incorporating ascophyllan to enhance overall quality.
A.In the past, Tonga mozuku was considered superior due to limited purification technology. However, advancements in refining have shown that Okinawa mozuku-derived fucoidan contains higher levels of fucose and sulfate groups, making it one of the highest-quality fucoidan sources available today.
