Trace Minerals Research Ionic Iodine from Potassium Iodide 225 mcg
Brand: Trace Minerals Research · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that Trace Minerals Research Ionic Iodine provides 225 mcg of iodine per serving, which is 150% of the Daily Value for adults [NIH ODS]. This is a significant dose, and our assessment is that this amount is appropriate for individuals with a known iodine deficiency or those under a healthcare provider's guidance. For most adults, the RDA for iodine is 150 mcg daily, so this supplement provides a meaningful boost [NIH ODS].
How it works
Iodine is a critical component of thyroid hormones, which regulate your metabolism, growth, and development. Think of iodine as the fuel your thyroid gland needs to produce T3 and T4 hormones, which control how your body uses energy [NIH ODS]. This supplement provides iodine in the form of potassium iodide, which is a well-absorbed source of this essential mineral [NIH ODS].
Safety profile
Data not available for specific adverse event reports from FDA data for this product. However, according to NIH ODS, long-term intake of iodine above 1,100 mcg daily for adults can lead to thyroid dysfunction, including hyperthyroidism or hypothyroidism [NIH ODS]. You should not exceed the tolerable upper intake level unless directed by a physician. The 225 mcg dose in this product is well below that upper limit for most people [NIH ODS].
Our recommendation
Our recommendation: Do not start this supplement without first consulting your doctor to check your iodine levels and thyroid function. This is especially important if you have a thyroid condition, are pregnant, or are breastfeeding [NIH ODS]. If you are cleared by your healthcare provider, follow the dosage on the label and do not double up on other iodine-containing supplements [NIH ODS].
