Features
- SUPPORT YOUR IMMUNE SYSTEM WITH SEAWEED - Fucoidan is a polysaccharide found in edible seaweeds that grow commonly in Japanese and Patagonian waters. Supplementing with fucoidan has been shown to support healthy immune function—making it important to any longevity strategy.
- LIVING TO 100+ - The residents of Okinawa, Japan regularly consume seaweed, and this region is renowned for its high proportion of people over 100 years old. A single vegetarian capsule of Optimized Fucoidan with Maritech 926 provides 88.5 mg of standardized Undaria pinnatifida extract, equaling the amount of fucoidan typically consumed daily in the traditional Japanese diet.
- INNOVATIVE EXTRACTION PROCESS - Maritech 926 fucoidan is sourced from hand-harvested, wild seaweed from the pristine ocean waters of Patagonia. An innovative water extraction process ensures fucoidan’s delicate molecular structure is delivered intact to provide all the critical nutritional benefits.
