Trace Minerals Research Ionic Iodine from Potassium Iodide 225 mcg
Brand: Trace Minerals Research · Form: LIQUID, SUPPLEMENT FORM [E0165] On Market
Our assessment
The evidence shows that Trace Minerals Research Ionic Iodine from Potassium Iodide provides 225 mcg of iodine per serving. This amount is above the Recommended Dietary Allowance of 150 mcg for most adults, but well below the Tolerable Upper Intake Level of 1,100 mcg per day. For most people, this supplement can help fill a dietary gap, but it is not a one-size-fits-all solution [NIH ODS].
How it works
Iodine is a critical component of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). Think of it as the raw material your thyroid gland uses to regulate your metabolism, growth, and development. The 225 mcg dose in this product is designed to support normal thyroid function, particularly if your diet is low in iodine-rich foods like seafood or iodized salt [NIH ODS].
Safety profile
Data not available on specific adverse event reports for this exact product from the FDA data provided. However, for iodine supplements generally, side effects can include a metallic taste, mouth and throat burning, and gastrointestinal upset. Those with pre-existing thyroid conditions, such as Hashimoto's disease or hyperthyroidism, should be especially cautious, as excess iodine can trigger or worsen these conditions [NIH ODS] [FDA data].
Our recommendation
If you have a known iodine deficiency or follow a strict vegan diet, this supplement may be appropriate. However, we recommend you first check your iodine levels with a healthcare provider. Do not take this supplement if you are already using a multivitamin or prenatal vitamin containing iodine, as you may exceed safe levels without realizing it [NIH ODS].
