Fucoidan Force® FAQs

What is Fucoidan?

Fucoidan is a complex polysaccharide made up of fucose and other important elements that has the potential to modulate a healthy immune systems as well as increase your body’s overall health and well being. It exists in different kinds of brown seaweed which go through an extraction process, resulting in a powder, pill, or liquid extract.

How is Fucoidan Extracted?

First the seaweed extract is extracted from the seaweed. Then the Fucoidan compound, one of several contituents of the seaweed is isolated from the crude extract. These are the processes by which Fucoidan is obtained and standardized. The extraction process itself varies from producer to producer, but Fucoidan Force®’ uses a gentle and proprietary cold-water extraction process that protects the fucoidan molecule to ensure maximum nutritional benefits.

Why is it important to only buy standardized Fucoidan?

If you don’t see the word “standardized” on the Supplement Facts label, then you won’t know how much actual fucoidan you are getting. Standardization is the process of determining the exact concentration of a substance in a crude material. For example, 300 mg of crude seaweed such as Undaria pinnatifida and Fucus vesiculosus, standardized to 75% fucoidan, means you get 225 mg of guaranteed fucoidan.  During our standardization process, fillers, salts, impurities, and other matter is gently removed from the seaweed through a patented cold water extraction process, leaving the delicate fucoidan molecules in tact to do their incredible work in the body. In this same example,  if 300 mg of seaweed was not standardized, all you would know is that you are getting 300 mg of seaweed, and nothing of the actual fucoidan content.

Should I be concerned about the iodine content in Fucoidan Force®?

Fucoidan Force® contains  20mcg (micrograms) per gram of product. It uses fucoidan from the wakame seaweed (Undaria pinnatifida) and Sea Kelp (Fucus vesiculosus). There is 300mg of extract in one single capsule of Fucoidan Force® which means each capsule contains 6 mcg of iodine, less than 5% of the recommended daily allowance.


mcg and ug are used interchangeably

The recommended daily value for iodine is 150 mcg, though the U.S. National Academy of Sciences lists the maximum tolerable level of iodine intake as 1.1 mg (1100 mcg) of iodine per day. To surpass this amount, you would have to take over 55 capsules of Fucoidan Force® a day.

Iodine is necessary for the human body to function properly. Fucoidan Force® provides a small dose of iodine on a daily basis. Always consult with your doctor before making changes to your diet, supplements, or medication.

What is the sodium content of Fucoidan Force®?

The amount of sodium in the wakame seaweed (Undaria pinnatifida) and Sea Kelp (Fucus vesiculosus) extract used to make Fucoidan Force is approximately 3.5%. Each Fucoidan Force® capsule contains 300mg of Undaria Pinnatifida and Fucus vesiculosus extract. This means you get about 14 mg of sodium per capsule. Keeping in mind that the RDA (recommended daily allowance) of sodium is 2,400 mg, 14 mg is a mere drop in the bucket.

Can I take Fucoidan together with other medications?

Fucoidan is 100% natural and does not contain harsh chemicals that can cause complications with other chemicals. Because of the blood-thinning properties of fucoidan, you should consult with a licensed physician is always recommended when adjusting medications or supplements.
