• Supports normal thyroid hormone production* — Low-dose iodine improved thyroid parameters in adults with endemic goiter (double-blind RCT). (NIH/PubMed — Kahaly G, 1997)
• Helps maintain healthy thyroid status within recommended intakes* — Small supplemental iodine doses altered thyroid function in predisposed adults (clinical trial). (NIH/PubMed — Reinhardt W, 1998)
• Supports appropriate thyroid feedback response* — Oral iodide at defined intakes produced expected, reversible effects on thyroid hormone secretion in healthy men (randomized dosing). (NIH/PubMed — Gardner DF, 1988)
• Backed by pregnancy guidelines on iodine sufficiency* — Evidence-based ATA guideline emphasizes adequate iodine intake during pregnancy/postpartum. (NIH/PubMed — Alexander EK, 2017)
• Supports maternal–child health where deficiency exists* — Iodized salt exposure before pregnancy improved iodine status and children’s cognitive outcomes (human data). (NIH/PubMed — Mohammed H, 2020)
• Supports cognitive performance in iodine-deficient youth* — Iodine supplementation improved cognition in mildly deficient schoolchildren (randomized, placebo-controlled). (NIH/PubMed — Gordon RC, 2009)
• Kelp intake supports healthy body composition* — Iodine-reduced kelp supplementation decreased body fat in overweight adults (randomized, double-blind, placebo-controlled). (NIH/PMC — Aoe S, 2021)
• Seaweed (including kelp) shows benefits for metabolic markers* — Human trials indicate improvements in glycemic control, blood pressure, and anthropometrics (systematic review of RCTs). (NIH/PubMed — Trigo JP, 2023)
• Alginate (from brown seaweeds) supports healthy glucose & lipids* — Human intervention lowered fasting glucose and improved lipids. (NIH/PMC — Liu J, 2021)
