There are products that claim to contain 60%, 80% or 100% pure Fucoidan. What do these percentages mean? Well, it depends. Sometimes they just claim that it is 100% natural and other times that it contains 80% Fucoidan per weight and not precisely based on purity. Until now, there is no official definition for Fucoidan. Fucoidan does not refer to a single molecule or compound. Instead, it refers to the many compounds (sugars) that are bonded together and sulfated to form the Fucoidan polysaccharide complex.  

The main components in Fucoidan include the monosaccharides, fucose, galactose, xylose, mannose, uronic acid, glucuronic acid and sulfated groups. Still, there is no official method established to measure the total Fucoidan content. Thus, each company that produces their own Fucoidan brand can claim their purity based on their own standards. So far, the best suggested method to calculate the Fucoidan amount is by combining the percent of the total carbohydrates, sulfate, cations and acetylation.

NatureMedic^® Fucoidan is the best product that utilizes Japan’s Okinawa Mozuku Fucoidan and Mekabu Fucoidan with approximately 85% purity. The Mekabu Fucoidan is Certified Organic from Australia. It is also suggested that if you are unsure of what you are buying, you consider requesting a copy of their Certificate of Analysis to verify that the Fucoidan being claimed is the same as the one being analyzed.

Even when a product contains 85% Fucoidan, it is necessary to check the actual grams of the Fucoidan that is included in each serving size. For example, even when a product utilizes 85% Fucoidan, it is not possible to refer that product as a good Fucoidan product if the content of a capsule is very low. 

This is not necessarily true. From what is known until now, the molecular structure and activity of Fucoidan varies depending on the type of brown algae used to extract it. Meanwhile, the Fucoidan extracted from different species has different functions.  For instance, there is a significant amount of sulfated groups in Fucoidan from Mekabu (Wakame). Results of numerous experiments and studies demonstrated that although this type of Mekabu Fucoidan offers effects that help to enhance health, other Fucoidan extracts such as Mozuku Fucoidan offers other type of positive health benefits. 

The results from the studies conducted to this day seem to indicate that the unique and complex combination structure of each of the Fucoidan engage through a synergistic interaction. Likewise, products that are combined with Mekabu Fucoidan and Mozuku Fucoidan just like ones in NatureMedic® Fucoidan are known to help enhance your health in a relatively broader and positively way. 

Effectiveness of Fucoidan was proven by numerous experiments and research papers as well as by many people who experienced Fucoidan and its benefits. However, there are many people who feel as if something is lacking. AHCC that has many data on the clinical studies administered on actual people and that which recommended by and utilized at numerous hospitals in Japan and US presents the health related benefits that are not offered by Fucoidan as the polysaccharides substance such as Fucoidan. Synergy between Fucoidan and AHCC gives birth to the best health product in the world.
