Brown seaweed family includes fucus (bladderwrack), undaria (wakame), and laminaria (kelp). Contains fucoidan (see fucoidan.md), iodine, alginate, and fucoxanthin. Alginate forms a gel in the stomach that reduces fat absorption (Slendesta). Fucoxanthin is a carotenoid that activates UCP1 in white adipose tissue (fat browning). HIGH iodine content — monitor thyroid function. Used in traditional Japanese medicine and Nordic folk medicine. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
