Role in the formula: Marine polysaccharide component
Fucoidan is a sulfated polysaccharide extracted from brown seaweed. Lab and early clinical work has looked at antioxidant and immune-related signals — not memory restoration.
Within Phytomem One it pairs with fucoxanthin as part of the marine side of the 10-ingredient list.
Do not interpret seaweed research as evidence that the finished chewable tablet reverses cognitive decline.
Practical caution: People with shellfish/seaweed allergies or thyroid concerns should ask a healthcare professional first.
Individual milligram amounts for Fucoidan inside Phytomem One are not published on the materials we reviewed. Always read the bottle label you receive.
