Fucoidan 50% is a particular algae polysaccharide found at the coastal areas of Korea and Japan. The supplement made from extracted seaweed kelp is rich in minerals. Research show it may improve diabetes and reduce the risk for blood clots.


Fucoidan 50% Polysaccharides is found in Asia at the coastal areas of Korea and Japan. The supplement made from extracted seaweed kelp has several nutritional and therapeutic advantages, as it is rich in minerals, such as iodine, along with fibers, proteins, antioxidants, and various carbohydrates. Research show it may improve diabetes and reduce the risk for blood clots.

Various studies suggest the polysaccharide can boost the immune defense mechanisms, for instance by increasing antibody production after vaccination. Other studies show it possess anti-inflammatory properties, which may help prevent infections due to inherent antiviral properties. Some researchers believe that fucoidan may be partly responsible for the extraordinary longevity observed in the Japanese population of Okinawa.

Fucoidan (sulfated alpha-L-fucan) is a complex polysaccharide found primarily in the cell walls of the brown seaweed (kombu, limu moui, wakame, hijiki). The supplement is rich in fucose, which is one of only eight known bioactive sugars essential for cell to cell communication.

Several types of marine algae polysaccharides exist, such as fucoidan, laminarin, ulvan, carrageenan, agar, and alginate. However, fucoidan remains the by far most studied, the most expensive, and the most valued for its health benefits.

Immune System

The ability of fucoidan to stimulate the production of white blood cells, the body’s primary defense against infections and pathogens, is a key factor in its immune-boosting properties. It also enhances the activity of macrophages, specialized immune cells that engulf and destroy harmful microbes. This dual action strengthens the body’s defenses against various infections and illnesses.

Cardiovascular Health

The potential of fucoidan to reduce blood pressure, cholesterol levels, and platelet aggregation makes it a valuable ally for cardiovascular health. By lowering blood pressure, fucoidan reduces the workload on the heart, reducing the risk of hypertension, heart attack, and stroke. Additionally, the ability to lower cholesterol levels may help prevent atherosclerosis, a buildup of plaque in arteries that can lead to heart attack and stroke.


The anti-inflammatory properties of fucoidan stem from its ability to inhibit the production of inflammatory molecules called cytokines. This action can help reduce inflammation associated with various conditions, such as arthritis, allergies, and autoimmune diseases. Additionally, it may help protect cells from damage caused by excessive inflammation, potentially slowing the progression of chronic diseases.

Antitumor Potential

Several studies indicate the fucoidan has antitumor properties, but more research may be needed. A study in overweight and obese adults suggests that it can decrease diastolic blood pressure and LDL cholesterol levels when used over a sustained period. Laboratory studies also suggest that fucoidan extract powder bulk has anticoagulant and antithrombotic properties.

Suggested use

The suggested daily amount varies, but it is generally between 100 mg to 4,000 mg once or twice daily. Please note that the substance may interfere with blood-thinning medications, as it has a similar effect….The phytochemical is non-toxic, biodegradable, and approved by FDA as Generally Recognized As Safe (GRAS) ingredient.
