Fucoidan AF Premium vs Nano Fucoidan – Key Differences Explained
This page explains the key differences between Fucoidan AF Premium and our former Nano Fucoidan product, including ingredient strength, added functional compounds, analytical verification, taste, and overall value.

We have sold three fucoidan products to date, including formulas containing low molecular weight fucoidan and nano fucoidan.
We are continuously developing new products with the goal of delivering something even better than our existing lineup. A truly good product is one where customers can genuinely feel the difference.
In every case, we have released products that significantly outperform our previous formulas.
Even when comparing only the fucoidan content, Fucoidan AF Premium greatly exceeds the earlier products.
It is designed to deliver a higher level of beneficial ingredients throughout the body and support overall health more effectively.
According to third-party analysis by the Japan Food Research Center, the fucose level — a key indicator of fucoidan — increased by 38.1% compared to the previous finished product.
Newly Added Ascophyllan Ingredient
Ascophyllan from Ascophyllum nodosum
Ascophyllan is rich in minerals and is considered nutritionally important. Compared to kelp, it contains about twice as much calcium, five times as much iron, more than twice the amount of vitamin A, and about fifteen times as much vitamin E, clearly demonstrating its superior nutritional value.It provides a well-balanced range of nutrients that are often lacking in daily diets.
Research on the effects of ascophyllan on cells and biological systems is currently being conducted at universities and other research institutions. Ascophyllan has been reported to show stronger activity than fucoidan, and combining ascophyllan with fucoidan is expected to provide enhanced overall benefits. Fucoidan AF Premium uses high-quality ascophyllan materials jointly developed by well-known universities, including faculties of medicine and pharmaceutical sciences.
The structural formula of ascophyllan differs from that of Okinawa mozuku-derived fucoidan. The diagram below is simplified for clarity, although the actual structure involves many additional components. While mozuku-derived fucoidan is primarily composed of fucose, ascophyllan is mainly composed of glucuronic acid. Fucoidan AF Premium Liquid type (900 ml) contains 900 mg of ascophyllan.
Verified by Third-Party Analytical Testing
Japan Food Research Center Analysis
Finished products are tested by the Japan Food Research Center, an independent third-party laboratory. This confirms ingredient content after manufacturing, not only at the raw material stage.
Post-production testing improves transparency and supports product reliability and customer trust.
Improved Taste for Daily Use
Designed to Be Easier to Drink
Because fucoidan supplements are taken daily, taste matters. Fucoidan AF Premium was refined through repeated prototype testing to achieve a smoother and more pleasant flavor than earlier products.
Balanced Formula and Natural Sweetness
The formula uses a carefully balanced ingredient ratio and natural sweet components such as erythritol to reduce seaweed aftertaste. No artificial fragrance is added.
Value Compared with Other Fucoidan Products
When comparing the amount of fucoidan, other beneficial ingredients, and overall quality, Fucoidan AF Premium is actually very cost-effective.
Some customers feel that the price is higher compared to other companies’ fucoidan products.
If you compare only the retail price, it may appear expensive at first glance.
However, the conclusion changes when you closely compare the ingredient content and formulation details.
Fucoidan AF Premium contains three key seaweed-derived components.
-
1.Okinawa mozuku–derived fucoidan extract (over 85% purity)
2.Water-soluble fucoxanthin (first developed in Japan)
3.Ascophyllum-derived ascophyllan — highly bioactive and rich in nutrients
Each of these ingredients is rare and highly valuable.
In addition, the formula contains high levels of amino acids, including essential amino acids and vitamins.
The total amount of functional ingredients reaches 466,108 mg per 900 ml, a level not commonly found in other products.
Raw material costs are more than five times higher than fucoidan products made from only one type of seaweed, such as mekabu, low-molecular, high-molecular, or kelp fucoidan.
In other words, even when taking the same volume, Fucoidan AF Premium delivers a greater amount of beneficial ingredients.
When you evaluate these factors carefully, you will see that this product offers excellent value for its cost.
Rather than focusing only on price or company size, we recommend checking ingredient amounts, purity, and formulation details when selecting a product.
We place strong importance on both the blending amounts during manufacturing and the verified ingredient levels in the finished product.
To eliminate customer concerns about whether the advertised ingredients are truly included, we conduct analytical testing through the Japan Food Research Center, a third-party organization.
