How does fucoidan work and what are the benefits

Fucoidan is a potent wellness extract found in various species of brown seaweed, including kelp and wakame. This substance has been attracting attention due to its potential health benefits, particularly in the context of Okinawa, Japan, which is renowned for its high concentration of centenarians.

The exact reasons why people in Okinawa live so long are not fully understood, but their diet is considered to be a major factor. This diet is rich in plant-based foods, including seaweed, which is a major source of fucoidan.


This prompted us to take a deep dive into fucoidan – and we found that it has an impressive range of health benefits:

Immune system

Studies have shown that fucoidan can stimulate the immune system to produce antibodies, that help to neutralize harmful pathogens and protect against infection.


Fucoidan has been shown to suppress the production of pro-inflammatory molecules which helps to reduce overall inflammation to cut the risk of chronic diseases, including heart disease, cancer, and arthritis.

Anti-cancer properties

Fucoidan has been the subject of research for its potential anti-cancer properties. Some studies have shown that fucoidan can inhibit the growth of cancer cells and induce cell death in certain types of cancer, such as breast cancer and colon cancer. Additionally, fucoidan has been shown to enhance the efficacy of certain chemotherapy drugs and reduce their toxicity, making them more effective and less harmful.

Gut health

One of the key ways in which fucoidan is thought to promote health and longevity is by supporting the gut microbiome. The gut microbiome is a complex ecosystem of bacteria and other microorganisms that play a critical role in overall health and well-being. Fucoidan has been shown to support the growth of beneficial bacteria in the gut, while suppressing the growth of harmful bacteria, which can contribute to chronic health problems.

Cardiovascular health

Another potential benefit of fucoidan is its ability to support cardiovascular health. This is likely due to its anti-inflammatory and blood-thinning properties, which can help to reduce the risk of heart disease and stroke.

Skin health

When applied topically - fucoidan can help to improve the health and appearance of the skin.

Skin nourishment formulations containing fucoidan have been shown to support the skin by reducing inflammation, boosting collagen production, and improving blood circulation.

Collagen is a protein that is essential for maintaining skin elasticity and firmness, and reducing its production can lead to wrinkles and sagging skin. By boosting collagen production fucoidan has been seen to improve the appearance of the skin, leaving it looking smoother, firmer, and more radiant.
