Published in Food & Nutrition Research
Methodology
Analytical survey of iodine content in commercially available kelp and seaweed products with intake modelling against upper limits
Key Findings
Iodine content varied enormously between products, and a single serving of some kelp products exceeded the tolerable upper intake level many times over.
Conclusions
Kelp supplements deliver unpredictable and potentially unsafe iodine doses.
Limitations
Product survey; no clinical outcomes measured.
Supplements Studied
Iodine content varied enormously between products, and a single serving of some kelp products exceeded the tolerable upper intake level many times over.
