Frequently Asked Questions

Is 1000 mcg of iodine safe?
The Tolerable Upper Intake Level (UL) for iodine is 1,100 mcg/day for adults. Sea-Iodine™ at 1000 mcg is just below this threshold and is appropriate for most healthy adults. Those with thyroid conditions (hyperthyroidism, Hashimoto’s) should consult their physician before use, as iodine sensitivity varies.

Why sea plant-sourced iodine over potassium iodide?
Sea plants provide iodine in a natural whole-food matrix alongside co-occurring trace minerals, polysaccharides, and phytonutrients that may enhance iodine utilization and provide additional health benefits beyond iodine alone.
