Fucus Nodosus seaweed

Fucus is a genus of seaweed found on the Atlantic coasts of Europe and North America. Fucus Nodosus may be a synonym for Ascophyllum nodosum (Linnaeus) Le Jolis.

Fucus nodosus product
As of 2009, Good'N Natural Fucoxanthin supplement says on the middle panel of their product label "Fucoxanthin." However, when you read the supplement fact panel, there is 1000 mg of the brown seaweed fucus nodosus and they do not say how much fucoxanthin is present in the 1000 mg of fucus nodosus. We found one site with the identical product under a different label that says the 1000 mg of the fucus nodosus seaweed has 0.25 mg to 0.5 mg of fucoxanthin. That's right. You are buying plain brown seaweed. Plus, there is 650 mcg of iodine in each capsule which is more than 400 percent of the daily value required by adults. In addition, this product has 35 milligrams of sodium. If anything, the label should say sodium on it since it appears to be the ingredient with the highest amount in this " Fucoidan " supplement.

Antidiabetic properties of polysaccharide- and polyphenolic-enriched fractions from the brown seaweed Ascophyllum nodosum.

We screened seaweed species from Atlantic Canada for antidiabetic activity by testing extracts for alpha-glucosidase inhibitory effect and glucose uptake stimulatory activity. An aqueous ethanolic extract of Ascophyllum nodosum was found to be active in both assays, inhibiting rat intestinal alpha-glucosidase and stimulating basal glucose uptake into adipocytes during a 20-minute incubation. All 3 Ascophyllum nodosum preparations improved blood antioxidant capacity.
