This page explains the major differences between Fucoidan AF Premium and ultra-low molecular weight fucoidan, based on ingredient content, purity, added functional compounds, manufacturing standards, and disclosed test data.
In addition to FFucoidan AF Premium, we are also an authorized distributor of ultra-low molecular weight mozuku-derived fucoidan. Many customers ask about the differences between these products, so we provide a structured and data-based comparison.
The main comparison points include fucoidan content, fucose level, raw material purity, additional functional ingredients, amino acid content, manufacturing certification, and product transparency.
A fair fucoidan comparison uses fucose content as a reference indicator. Based on third-party laboratory reports, Fucoidan AF Premium shows significantly higher fucose levels when equal liquid amounts are compared.
Fucoidan AF Premium achieves 3.45 times the fucose content compared with ultra-low molecular weight fucoidan. (Based on an equal liquid volume comparison.) This value is based on analytical reports issued by the Japan Food Analysis Center, an independent third-party organization, ensuring a fair and objective comparison. If you want to choose a product that contains more fucoidan, it is important to select one with a higher fucose content.
Fucoidan AF Premium uses Okinawa mozuku and achieves purification levels above 85%. Higher purity is widely recognized as an important factor in fucoidan quality.
Fucoidan AF Premium contains fucoxanthin.
Fucoxanthin is a carotenoid that has been widely studied and is said to offer health-supporting benefits similar to fucoidan.
Because only a small amount can be extracted from seaweed, fucoxanthin is considered a rare and valuable ingredient.
Fucoxanthin is naturally oil-soluble and does not dissolve easily in water. However, the fucoxanthin used in Fucoidan AF Premium liquid is a water-soluble form developed in Japan, designed to dissolve in water for improved usability.
When taken together with fucoidan, these ingredients are expected to complement each other, providing enhanced combined support.
Fucoidan AF Premium contains the notable ingredient Ascophyllan.
Ascophyllan is a functional component extracted from the seaweed Ascophyllum nodosum and has a different structural formula from fucoidan derived from mozuku.
This seaweed is also highly nutritious. Compared with kelp, it contains about twice as much calcium, five times as much iron, and more than twice the amount of vitamin A.
Fucoidan AF Premium is the first product in the industry to combine three beneficial seaweed-derived components — fucoidan, fucoxanthin, and ascophyllan — achieving a well-balanced formula designed to provide stronger overall health support.
Fucoidan AF Premium is formulated with a rich amount of essential amino acids needed by the body.
Especially for those who want strong daily health support, it is designed with a generous blend of key nutritional ingredients.
Compared with low-molecular-weight fucoidan products, it contains about 1.8 times more essential components, including amino acids and vitamin B6.
Because this is something you take every day, safety and reliability are extremely important.
Fucoidan AF Premium Liquid is manufactured in a safe and reliable facility certified under the international ISO (International Organization for Standardization) standards.
Only raw materials that have passed strict quality inspections are used.
