  NIH/PubMed — Murray M, 2021)
• Helps reduce daily energy intake — Daily pre-prandial sodium alginate (seaweed fiber) reduced mean energy intake in free-living adults (randomized trial).
  (
  NIH/PubMed — Paxman JR, 2008)
• May enhance satiety during meals — Alginate-based preload increased post-meal satiety and influenced gastric emptying in normal-weight adults (randomized trial).
  (
  NIH/PubMed — Jensen MG, 2012)
• Provides dietary iodine that influences thyroid indices — A sushi/seaweed meal increased urinary iodine and transiently altered thyroid markers within normal ranges (randomized dinner study).
  (
  NIH/PubMed — Noahsen P, 2020)
• Adjunctive support for weight-management programs — Alginate supplementation alongside calorie restriction improved weight loss in obese adults who completed a 12-week program (DB-RCT).
