Dr. Lisa Ann,
I don't know much about fucoidan gel and its relative potency compared to ingesting fucoidan as part of a whole food in its live form. I checked out the NIH for research studies on fucoidan and that's when I decided to become a distributor for Original Limu. I know people who are taking the liquid form (my own dad included)and are using an unofficial dietary protocol that starts with 4 ounces a day and progressives to 12 ounces at the peak of ingestion, for a minimum of 90 days.
We have thankfully seen good results but I know this is largely dependent on each individual's body chemistry. Sorry I don't have any information about fucoidan gel.Have you checked the web for information aoubt the natives of Tonga in the South Pacific? I know this has been a staple in their diet for over 3000 years, and I recently met a fellow who grew up in Samoa and remembers harvesting limu moui (the seagrass in its native form) with his brother as children and selling it to their neighbors.
Good luck.
Sharon
