How to choose good Fucoidan

Beginning from the conclusion - How to choose good Fucoidan

Don't be concerned with the "raw materials" of Fucoidan.
Any raw materials are always "purified" and "extracted", meaning there won't be any huge difference between them.

It's important not to choose products that don't list the "purity".
*In general, anything over 85% should be fine.

The dosage guideline should be over 1g of a product with 85% purity or more per day, at least around 3g.
Be careful of products that suggest you take much less than this.

The functionality of sulfate groups is the same as long as they exceed 13%. There is no difference in functionality at anything above this.

Don't worry about high-polymers and small molecules.

High-polymers don't have great absorption but have a full effect inside the body
Small molecules have good absorption but have low functionality inside the body

Preface... About iodine

Before we touch on how to choose Fucoidan, women in particular should take some time to learn about "iodine"

There is one thing you must not forget when it comes to iodine.

"Thyroid gland malfunctions"

Names of these diseases are Grave's disease (hyperthyroidism) and Hashimoto's disease (hypothyroidism).
Symptoms of Grave's disease (hyperthyroidism) include feeling sluggish, lacking motivation, sexual dysfunction, and excessive hunger.
A symptom of Hashimoto's disease is immediately gaining weight despite not eating much. In general, there are many cases where someone doesn't feel "sick" and goes their whole life not realizing that they have a thyroid gland malfunction.

One thing that you should absolutely avoid excessive intake of when inflicted by this is "iodine".
*In the case of hyperthyroidism, symptoms worsen when taking excessive amounts of iodine, which is a raw material of thyroid hormones.
*In the case of hypothyroidism, excessive intake of iodine causes the body to over-exert itself in trying to process it, resulting in becoming fatigued and symptoms worsening.

Women especially should avoid products that don't list how much iodine they contain.
All of our products won't cause any problems if you have a thyroid gland malfunction.

Be especially careful of products that use seaweeds besides mozuku as raw materials, such as kombu or mekabu.

This is something that is not generally well known, so women especially should take this opportunity to get a checkup at a medical facility and also deepen their knowledgeable about the thyroid gland and iodine.

POINT 1 Is there a difference in the characteristics of Fucoidan depending on the raw materials?

There is mostly no difference depending on the raw materials, so don't worry about it.

In Japan, the origins of raw materials are largely split into three choices.
Fucoidan doesn't have any clear standards like electronic products, and as we will touch upon later, since it is sold based on image and title, it should be noted that a high price does not mean a quality product.

Origin of Okinawan mozuku

Fucoidan was actively discussed in publications around 1995 and mostly used materials that were purified from Okinawan mozuku.
Fucoidan from other sources underlays the foundation of these publications.
It therefore is a raw material with as few mistakes as there can be.
It also has little alginic acid making it possible to purify Fucoidan at a lower cost than mekabu. This allows us to produce products with high purity at low cost.

Mekabu, kombu, etc.

There are companies that claim to be successfully making Fucoidan with few contents and quality higher than that of mozuku, but they have few samples which doesn't lend much to the veracity of this.
Basically, no matter where you get it from, calcium is calcium and won't be any different.
There are many people that can't digest iodine the more there is, and products that eliminate iodine tend to be higher in price.

When considering the raw materials of "Fucoidan" functional food products

Which raw materials are best based realistically on quality and price when wanting to effectively give your body Fucoidan as a functional food product?

There are some very important things that should be noted here.
No matter which raw materials it is produced from, Fucoidan is Fucoidan.
The required costs for the purity and amount of Fucoidan included in one product are important.

For example, a Fucoidan product made because it has five times the concentration of Okinawan mozuku will have low purity (in which case, the amount is naturally not displayed the majority of the time), and just one of these products will have a low amount of Fucoidan. There's no meaning if the price is the same or higher.
There's no meaning if the merit of being derived from high content materials is not reflected by high content and low price.

POINT 2 Don't buy products that say they "only" contain Xg of Fucoidan.

To put it simply, in the case of Fucoidan, if 10% or more overall contains Fucoidan, then there would be no issue with indicating that it is "Fucoidan Xg" overall. Therefore, products that only tell you the contents in grams without mentioning the purity rate are likely to have a low concentration. Point 2 is to be weary of this.

There are products that claim to be 100% Fucoidan even if their quality is like that seen in the illustration to the right.
On the right is the quality of technology around the time in 1995 when Fucoidan research began to flourish in Japan.

Don't trust it when you only see expressions such as "high purity" or "concentrated".

"The Fucoidan used in all of our products has a high purity of 93% (approximate value of 85%)."

*In addition, we can only measure the primary component "frucose" of Fucoidan.

This is because it would be false to write Fucoidan and would be illegal.

The more sulfate groups contained in Fucoidan, the better?

Watch out for Fucoidan products that contain a very low amount of sulfate groups, and also be wary of websites and products that claim to have a high functionality due to having a lot of sulfate groups.

It may feel like it must be a good product if the amount is high, but this is incorrect.
The important number for Fucoidan sulfate groups is "13%". Anything more doesn't improve functionality.

POINT 3 Functionality requires "absorption"

Something that's been dried and put into a capsule is the best and general form of a supplement.
Liquid-type Fucoidan products melt this down to a liquid.
Since this form will have negative ions, a liquid is a bit better at absorption than a solid.

However, if the stomach is in a normal state, there won't be that much of a difference in absorption for a solid object (capsule-type) compared to liquid-type one.

What's the difference between Fucoidan and Fucoidan extract?

Actually, they are the same thing.
"Extract" gives off the impression that it is concentrated, but it actually is defined as a "liquid".In other words, a solid object is called Fucoidan, while a liquid-type one is called Fucoidan extract.

Care must be taken since the "dosage guideline per day" is different depending on the company.

Overlooked POINT

We have had a customer that once mistakenly thought that a higher priced product was cheaper than our 93% purity Fucoidan.

This was because while the Fucoidan contained in one capsule was a mere 400mg, that company's "dosage guideline per day" was listed as "one capsule".

We recommend based on Fucoidan research that all dosages be 1g to 3g per day.

The recommended dosages for supplements that aren't pharmaceutical products don't adhere to research materials and can be freely decided by a company, so you need to be careful.
