3 Ways to Effectively Take Fucoidan

Fucoidan in Algae

There are different types of algae in the ocean.  Among them, the brown algae that receives a small amount of light contains a unique compound called Fucoidan, a sulphated polysaccharide. Fucoidan has attracted a lot of attention from the public because of its excellent anti-cancer effects.

Anti-Cancer Effects of Fucoidan

Fucoidan has various health benefits, but the reason for its full-fledged attention is that it has been proved that it induces cancer cell-death (apoptosis).

Every cell has its own life cycle, repeating birth and death. However, when a cell undergoes multiple mutations and turns into a cancer cell, the cancer cells continue to divide and multiply and develop into cancer. Cancer never dies but infinitely grows (infiltration growth), which causes fatal damage to the human body.

Many published papers report that Fucoidan has the ability to inhibit the proliferation of cancer cells and induce cancer cell-death. This unique anti-cancer activity of Fucoidan is explained by two strategies: inhibition of the cell cycle and promotion of self-digestion. The mechanism can be explained. Let’s take a closer look at the link below.

How to Take Fucoidan Effectively

1.Take high-purity Fucoidan extract.

You might think that eating a lot of brown algae will be a way to take Fucoidan. However, eating algae does not mean that our body is selectively digesting enough quantity of Fucoidan. As 1 kg of brown algae only contains 1-10g of Fucoidan.  To take 1-10g of fucoidan; the amount known to help support immunity, you need to eat 1kg of brown algae, which is quite difficult to do routinely in daily life.

Therefore, in order to consume enough amounts of Fucoidan, it is more effective to eat high purity Fucoidan products that are purified and purely extracted.

2.Better to take a combination of different types of Fucoidan

Widely used brown algae for Fucoidan extraction are Mekabu, Mozuku, Bladderwrack, Kombu, etc. Fucoidan is a common word for the sulphated polysaccharide extracted from brown algae but according to many research data, the effectiveness of fucoidan varies depending on the type of brown seaweed as the molecular structure of fucoidan is different by algae species. 


Mozuku Fucoidan from Okinawa Japan is best known for cancer apoptosis; Mekabu Fucoidan is the best for preventing cancer angiogenesis; Bladderwrack Fucoidan is best as an antioxidant and in treatment for women’s cancers.

Therefore, it can be inferred that mixing the different types of Fucoidan would have more diverse and better effects than using only one Fucoidan extracted from one type of algae.

3.Quantity matters. Cancer patients need to take 3-6 grams per day to expect benefits from Fucoidan.

According to worldwide research articles and many Fucoidan books from Japan, it is recommended that the average person take 0.5 to 1g continuously, and 3-6g should be taken every day, especially for patients with cancer.

Since our natural immunity increases during the day but gradually decreases toward the night, it is recommended that Fucoidan should be taken four times a day (morning, lunch, dinner, and before bed; taking more before bed) to activate immune cells more effectively.

Conclusion & Fucoidan sample

To sum up, it is recommended to take a consistent daily dose of high purity Fucoidan extract depending on your condition. However, the high purity fucoidan products are not cheap as extracting high purity Fucoidan requires expensive manufacturing and raw material costs.  The higher the purity, the higher the price.  

If you want to take Fucoidan for immunity, 500mg – 1g of Fucoidan would be enough.  However, if you are looking for Fucoidan with critical health concerns, 3-6g of high purity Fucoidan should be considered but these products are expensive, so before making a purchase, it is not a bad idea to compare several companies and request samples if they are offered.
