Aakre I, Solli DD, Markhus MW, Maehre HK
Published in Food & Nutrition Research, Vol. 65
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.
